Science fair (DrBacchus/flickr/CC-BY-2.0)

If you've got advice on how to achieve middle school science fair glory, one of our listeners could use a little help...

The fair's around the corner, and he's stumped:

I have to think of a science fair project and i cant think of one, so i thought that i could email radiolab. will you please send me some ideas? if you can, please reply to this ASAP. You don't have to do this, and i know that you are busy, but if you have the time, could you please do this? THANK YOU!!

All right all you science enthusiasts out there! If you're feeling inspired, and want to help this kid come up with a great idea, post away!

Hello!

Do you have a computer? Do you like using it? Do you have information about your classmates, or a particular animal or band you like? You could answer a geographic question about the relationship between two things using a new technology called GIS. You can download a free trial copy of ArcGIS and compare two geographic relationships like: how many of my classmates live near a river and how many of my classmates prefer water parks versus amusement parks? First, you give them a survey using the Likert 5 scale. Next, you put the results in an Excel table. Then, you have statistics about your class! Now, you will use Geospatial Science (the act of putting your class' information onto a map using ArcGIS so you can compare who lives near water, and also who prefers waterparks.) ~H.

Does the human body obey Hooke's Law? Most students have learned that for some materials, extension is proportional to applied force. If you hang someone from a bar above the ground and place their feet on a weighing scale and move the scale up and down so that the downward extending force is their weight minus the scale reading and then measure their length from knuckles to heels, I reckon you could plot a F-ext graph which might be quite straight (don't exceed the elastic limit!).

I teach kids about energy, including small group projects. A couple favorites are:

1. Taking the I-V curve of a solar cell. You need a small solar panel, a handheld digital multimeter accurate to millivolts and fractions of milliamps, and a handful of different sized resistors.

2. Building a wind turbine or water wheel with a generator built by the students. I found instructions online for building the generator and it doesn't have to be geared down the way a store-bought motor does-just attach the turbine blades directly to the generator axle. Once it is built, you can graph how much voltage you get at different wind (fan) speeds or water heights. Again, you need a small hand-held digital multimeter to measure the voltage.

Homunculus man!

Our frontal Lobe has a disproportionate somatosensory and motor distribution in the cortex. It has to do with dexterity with the more dextrous a part of the body having a larger distribution.

It's a really weird looking distribution when you make a 3D model of it and its informative on how our brain works. Probably wont win anything but it is interesting and educational.

Like everything in medicine understanding the physiology is a prerequisite of understanding the illness. Strokes, Demyelinating Disorders, head injury etc, all stem from the very important somatosensory and motor distribution in our brains!

Go forth and educate yound one!

1. You could do a project about why things ripen the way they do. It is due to ethylene gas. Compare unripened fruit left in brown paper bags vs. in the refrigerator, white light vs. color varied light, and so on.
2. I did another project on proving the claim that 7 numbers/symbols are the limit to an individual's short-term memory bank. I used my science class as participants and had them try to remember sets of 3,5, and 7 numbers&letters.
Gave them an amount of time to try and memorize, removed the sequence, waited a little, and then told them to write down what they remember.
Made a table and graphed.
3. Maybe figure out a project about synesthesia. A condition in which one type of stimulation evokes the sensation of another, as when the hearing of a sound produces the visualization of a color. (free online dictionary)
Create a project that stimulates how a certain combination would affect your life. Or create a way to demonstrate one of the many types of synesthesia.

For any project do research so your introduction is well-written. I am not sure if this is a contest but it always helps judges to really enjoy your presentation.

Darryl from Canada eh?

I saw a very simple, yet ingenious, science fair project years ago. This kid had several toy cars, and he fixed various pieces of cardboard on top of them to make them more aerodynamic. He attached a rubber band to the front of each car and, using an electric fan, measured how far the band stretched - the longer the stretch, the less aerodynamic the car. Another method could be to run the cars down a track (like "Hot Wheels") and see which goes further.

I never came up w/ a good science project while in school which has often irked me - enough to start a list of potential research ideas, which I'm happy to share w/ U. Like a lot of things I have been taught, I didn't really 'get' the scientific method until later, after things stewed around in my head & mixed with 'real life' experience. There are a lot of great suggestions & advice already posted. Here's a list of my more scientific (as opposed to sociological, to some degree) research ideas:
- Maximum utility of water temp vs amount used, i.e., what's the best temp to set UR water heater? Take into acct the cost of the water & the fuel to heat it, how long it tends to wait, heated, to be used. Does the pressure of hot water coming out of the faucet 'squeeze out' any of the output of the cold water? Vice versa? If you turn up the temp of the water at the water heater, do you use less of the hot water at the faucet? Save money?
- How is sea salt better than regular table salt? Or is it? It's touted everywhere lately.
- Study demographic patterns of the order in which people board buses (or other forms of public transit; using school buses will limit the demographic variables, like age, that U have available to U). Is there a detectable pattern? Does it vary based on how crowded the bus already is, the demographics of the neighborhood the stop is in, AM vs PM rush hour, etc.?
- Is there a placebo effect when pills are larger or contain more overall mg's, but are otherwise equal in potentcy (at least in vitro) or the amount of active ingredient it contains?
- Do indoor house plants know when it's raining outside? Maybe instead there's a correlation with the amount of sun / clouds? Put as identical as possible plants inside & out where they'll get the same amount of light (does the filtering of sunlight by the window skew the results? The air temperature, etc?), measure the amount of rain (& its chemical make up, duration, temperature - or collect some of it for use w/ your indoor plants instead of tap water), then water some of your indoor plants at the same time, duration, etc. as the rain falls on the outdoor plants, & water (using the same water, same amount, & keeping all else equal) the other indoor plants on a different schedule, like when it's sunny outside, or the full week's worth of rain all at once, for ex. After a few weeks is there any measurable difference btwn the difft sets of plants? As in any study, if there's a possible effect from a variable you aren't able to keep from varying, state it as an alternative explanation for your findings.
- What makes a weed a weed? Who decides? Based on what? Is it different in different cultures or climates? Is one person's rose another's dandelion - or not?

The purpose of a Science Fair project is to explore a question that hasn't been answered before. If you are going to various websites and copying the questions and procedures, you aren't doing science, you are following directions. I recommend that my students find a topic they are interested in and ask a question that would help them to understand that topic better. The best science fair questions tend to be the simplest ones. Some of the best projects I've seen were "What's a chicken's favorite color?"; "Which soccer shin guards offer the best protection?" and "Do expensive sports shoes help you perform better than less expensive brands?". I've had other students inspired by radiolab posts in the past. This past year, I had a student that wanted to explore the placebo effect and so decided to test how much longer people were willing to hold their hands in ice water wearing a glove that claimed to have a new form of insulation vs. a regular glove (both gloves were identical).
Choose a topic you want to know more about and then ask your question. Once you have your question, your teacher should be more than happy to help you design an experiment. Remember, your teacher's want you to do well and will help you in any way they can. If you let your teacher know that you are interested in exploring a particular question, but don't know where to begin, he or she will gladly give you guidance.
If you have a question and your teacher is not willing to give guidance on how to explore it, please feel free to email me and I can give you assistance.

Great comments (maybe we should be mining middle school science fairs for show ideas). I just wanted to add my favorite (an oldie but goodie):

In 1997 Nathan Zohner did his middle school science fair project on the dangers of Dihydrogen Monoxide.

He got a bunch of people to sign a petition to ban DHMO because:

-it is a major component of acid rain
-causes corrosion of certain metals
-contributes to the erosion of our natural landscape
-can cause sever burns on contact with skin
-may cause death when ingested

Despite all this, DHMO is currently used:

-in numerous industrial processes
-as an additive in many food products
-as a fire retardant

And it has been found in rivers and lakes across the country.

All true, but since Dihydrogen Monoxide is really just water (H2O), Zohner's project was actually a lesson in gullibility and critical thinking and the way the truth can lead to different conclusions.

For one of my projects I took the pH of water samples from various points of creeks throughout my town, then tried to correlate differences to natural phenomena (half of the samples were taken downstream from a limestone ridge which made them more acidic).

If your interested, here is a link displaying a guide on how to build your own Theremin. If you didn't know a Theremin is a musical instrument that creates a pitch and tone depending on the position of hands (this one works a little differently as you will see in the link)

The assembly is real easy (I built it in about a day) and it the parts will set you back about $15.00US

The project would highlight concepts in electronics, physics, and just plain awesomeness.

Here is the link and the best of luck to you

Science fair veteran here! I did science fair projects every year in middle school and I managed to collect a few medals for them at the county science fair. Probably one of the highlights of my career :P
One good idea is to find something that somebody says is true and then test to see if they're right or if they're just making it up. For example, there's a type of honey from New Zealand called manuka honey which lots of people say is very good at killing bacteria. For one of my science fair projects, I plated some (non-dangerous) bacteria and tested to see if the manuka honey would keep it from growing, plus how it compared to local honey (from near where lived), bleach, and water. When I did this, I found that the local honey was a lot better at killing bacteria than the manuka honey! It was not the result I expected, but it was important because it showed that you can't always trust labels. There are lots and lots of other things which claim to be good for you or work better in some way but don't have a lot of science backing those claims up. It's always interesting to see what is and isn't true. So I suggest finding a product and testing its claims - does this one work better than that one, does this really do what it says it does, etc.
An example of this I was thinking about recently was the lactase pills they sell at the drugstore for lactose intolerant people. To work well, those capsules can't dissolve too quickly in acid, because then the lactase enzyme would just get denatured (messed up) in the stomach acid and wouldn't be able to help digest lactose in the small intestine. So a good project might be testing a whole bunch of different types of these pills - vegetarian (cellulose) ones, gelatin ones, "fast acting" ones, etc. and seeing how fast they dissolve in an acid like white vinegar heated up to body temperature. Based on how they fast they dissolve, you can figure out which type is the best. You're welcome to have this idea if you want, but the important thing is to make sure that the project you do answers a question that is interesting to YOU! Good luck :)

A friend of mine once raised three rats (I think they were rats) feeding one only milk, one chocolate milk, and one coca-cola for a few weeks or a month. She weighed them and kept track of weight gain or loss, and she observed them on how fit each seemed after an extended period on each diet.

Choose something you care about, or find interesting... What's your favorite product, and why do the advertisements "claim" that it's better?

In middle school I did a project to determine if Bounty paper towels really were the "Quicker Picker Upper" as they claimed-- measured for time and efficiency of dye absorption. Easy to measure, fun to demonstrate, useful to know. Bounty-- and the project-- both won! Good luck!

Do an analysis of various social media forums (fora) for the quality of answers you get to this same question. You would analyze the volume and quality of responses. Quality, of course, is a tricky matter. I'd suggest two complementary approaches.

First, recruit several impartial people with science backgrounds; you might find some local professors willing to help, if you ask nicely. You would give them each all or a random sample of the suggestions, removed from their source (with source-identifying info removed), and ask them to rate the quality of the suggestion, providing some guidelines for quality using one or more metrics based on those guidelines. The guidelines might be yours, or you could solicit guidelines from them, but they should all use the same guidelines. You'd then average the scores for for each posting, and compute the aggregate scores for the social media where they were suggested.

The other approach is more computational, though not necessarily more objective. That would be to do a textual analysis of the suggestions. You're not, here, looking for length, which you would have already included in the volume analysis I mentioned a the top. Rather, you'd look for linguistic complexity (there are tools around that do this) and for frequency of quality-signifying words or phrases. The quality-signifying terms could be positive or negative indicators, and choosing them is the difficult and subjective part of this approach.

Frankly, if you do the other things I'm suggesting, you don't really have to do this last bit at all. Instead, you could use the other measures to identify quality-signifying terms. That is, use volume, linguistic-complexity, and expert opinions to identify good suggestions. Then you could use that to teach a machine learning system (open source versions exist) to identify good suggestions.

Build a cloud chamber! It lets you see the paths left by cosmic particles as they whiz through -- you can even use a magnet to see their charge. My dad helped me build one when I was a kid and it was quite awesome.

I'm a biology teacher and it never ceases to amaze others how much bacteria can be found on surfaces, air vents, body parts etc. YOu have to get some nutrient agar, and maybe some help pouring plates. Pick a variety of things to swab, or try the same surface before and after cleaning. One year my students tested my keyboard and it was horrifying!

For your display, make sure it looks good, and it doesn't hurt to hand out candy.

Good luck!

It might be fun to measure biodiversity and abundance in people's backyards. Use insects, it's easy to collect bugs for 2 hours then figure out which insect 'orders' they belong to. Count both the number of different orders (diversity) and the number of bugs in each order(abundance). Do not try to figure out the family, genus or species, you will not be able to. Then repeat in somebody else's yard which is similar (in the suburbs, sometimes exactly the same) except for 1 variable, say... do they get lawn treatments of fertilizer or (even better) pesticides? Maybe they differ by species of grass or number of shrubs. But pick some variable that you can *hypothesize* would correlate with insect diversity. Use a field guide (Peterson's, by Borror et al., is probably the best/easiest to use) to id your orders. Good luck, happy bugging.

If there is a college near you, look at professors' web pages and see if they are doing something that interests you. Then email them (you may have to email more than one to get a response). Ask if they have any projects that would be reasonable for a student of your age or if they have any suggestions for science fair project that is related to their area of research (almost ALL professor like to talk about their research!). I study polymers and might suggest to a middle school science student that he/she look at how they are recycled or how much plastic (polymer) is used in water or soda bottles. Or study why polymers are so different than regular (small) molecules. You could make some polymers to illustrate the point.

The best thing to do is find a general area or areas that interest you first. I've always been interested in chemistry, food, and consumer products.

In junior high I did one project on microbiology. I got petri dishes and coated the agar with 2 kinds of bacteria strains commonly found on hands, one more harmful than the other. I put hole punch circles of paper that were soaked in different germ killing products on each dish (for example, hand soap, laundry detergent, bleach). After incubation, I measured the surface area covered with visible bacteria.

Another year I did a project kind of on psychology/human behavior. I got clear koolaid and dyed it different intensities of red. Had people rate how sweet each was, when only the color changed and not the taste.

Other questions you could consider:
Do foods containing preservatives stay fresh longer than foods without them?
Does ripening deplete the nutritional content of fruits/vegetables?

May. 03 2012 03:08 PM

How about the effects of music devices on hearing? Survey different age groups, their experiences with loud music or noisey work environments and the impact. How people can protect their hearing and the impact of hearing loss (which is tragic).

Or, space dust. Tons of it fall to Earth. You can actually collect it from your houses other building gutters! Safer at the bottom spout of course. What's it made of and what impact does it have on us? Can it be collected to benefit us in some way?

The effects of lighting on people at work and students. I'm convinced those florescent lights hindered my concentration as a student. How does the type of lighting effect people and their brains?

In middle school, I modeled all physical systems in a cutaway of a worm with colored plasticine and won third prize. I supported the segments on a looped wire armature on a cardboard base and rolled out smooth plasticine coverings with a rolling pin. The value was in the detail of the model and the accompanying writeup which demonstrated that I had learned the nomenclature of the structures and functions of each. The result was exactly like the picture in the Biology book from the library. A little too perfect since I was suspected of having adult help. Make the model large enough to be impressive.

I built a camera obscura once when I was younger out of foam core poster board and used an old magnifying glass as the lens to demonstrate how our brains invert the image and display it to our brain to "see" it correctly. The image on the screen projected from the lens will be upside down and backwards. The mind is always a facilitating topic for discussion. Perhaps you could modify it to "see" different kinds of images.

Psychology and Economics come together to make a fairly new science: behavioural economics. This process of gaining input from so many people around the world is a great example using a new type of "heuristic" (which is a fancy way of describing common-sense, or rule of thumb), which some people call "crowd-sourcing". In previous generations, a heuristic was probably formed through reading books, listening to experts, growing up in a certain family, and learning through school. It took most of your life to form a heuristic and was unlikely to change very often. But in these modern times, technology can bring together a huge number of diverse opinions to turn someone into an expert in next to no time. You might even frequently change your heuristic in the face of a sudden, gigantic input of new information (an example would be the KONY stuff in the news recently ... how much did any of us know about Joseph Kony before Facebook?). Thanks to technology, you get the benefit of a million brains all tuning in together. An example of this is wikipedia ... in your parent's day, an encyclopedia was handed down by some professors, and it remained the authority on fact as long as that book remained on the shelf. These days, a million people can chip in to form a consensus on any given subject on wikipedia, and it might change next week! This has strengths and weaknesses ... you could spend some time thinking about the pro's and con's of this new way of establishing facts and definitions. Is it fairer? Is it actually correct?

By asking Radiolab to contact their vast audience, you've used crowd-sourcing to answer your question. I would simply show this process in action! It would be a very impressive science project. Good luck!

You could make a few winogradsky columns with water and sediment from different water sources near where you live, or with different things the microorganisms could eat in them (newspaper, vegetable peelings... anything organic, basically.) You can also try covering parts of the tube up with construction paper to create environments without light. Set them up for a couple weeks and see what grows!

http://en.wikipedia.org/wiki/Winogradsky_column

If you need more information, Betsey Dyer's "A Field Guide to Bacteria" has a section on them, as well as good descriptions of all the sorts of bacteria you might find growing in them.

Not an idea, but some advice:

I recently judged a science fair at the middle school level and I can tell you that the projects that stood out were the ones that asked a reasonable question and performed an experiment that tried to answer it. It doesn't have to be complicated or sciencey, but try to make sure it's original and testable. The most important thing is that you have a hypothesis (your guess at what you think is true).

One student thought that colder hockey pucks would have less friction when sliding than warmer hockey pucks and that they wouldn't bounce as well, so he conducted three different experiments to test it. For the first one, he pushed three pucks of different temperatures with the same force to see which one would go farther. He did this many times to make sure he had an actual pattern (repetition) and he did his best to make sure there were no other factors influencing the outcome (controlled experiments).

There are questions we can ask about things we see every day which we don't have answers for. Try thinking about your hobbies - sports, music, video games, chess, photography. Start asking questions about them.

My son once won with a project demonstrating chaos. We got a big hamster wheel, hung little tilty cups on it -- making a miniature water wheel -- ran a hose over it from above (keeping the angle and flow constant) and clocked the reversals. Then he charted it out on graph paper taped together, which we reduced down at Kinkos for the display. I think I got the idea from a description of water wheel behavior in James Gleich's famous book, Chaos. (GREAT science read.) Fun, cheap, smart and we got to play in water.

Good luck!

Do something that interests you. Do you have a hobby, or play a sport? Like playing video games? You can think of a question to test that is related to something you're already familiar with. Video games- do something on reaction times. Music- how different music affects heart rate or blood pressure. Sport-(golf) what golf balls travel the farthest? Are they the more expensive balls? These are just a few examples to get you thinking. Good luck!

It is spring and people are starting to clean up their gardens. I think it would be really cool to do something on invasive species of plants. Many people do not know what types of plants are invasive and they can quickly takeover an entire garden or plot of land, stealing all the nutrients and sunshine.

I imagine there is a local park that might have a walk on invasive species or a guide you could use. You can then identify the biggest problems in the area and provide guidance on how to get rid of them and stay rid of them.

Are any of your friends or people in your school/neighborhood bilingual? See if they perform a certain task differently than people who are monolingual.

Something involving the Gulf of Mexico, recovery of the oil spill, chemicals still present, etc. would be interesting. You may live really far from there though, but I am personally drawn to read about every independent study done there. I currently live in Oregon, but I grew up on the coast of Mississippi and that spill is often on my mind.

I helped a friend's little brother do their science fair project with dry ice and making bubbles. Dry ice isn't the safest thing... but it looks really cool!

I made some videos on youtube. it's pretty easy to do in a round lipped bowl with warm water, dry ice, and a rag soaked in dish soap. Look up: How to make a dry ice bubble, or Dry ice Music Video.

The science involves sublimation and catching the released CO2.

I can't think of something off the top of my head, but it is Spring, so I bet there are some really great biology projects you could do about stuff creatures do when the cold weather is finally over. You could see it happening as you study it and do some field research of your own!

Nice little wizard to help you choose a project depending on grade, time and interests.

something about insect behavior might be really interesting and unique ie I've always wondered why rolly pollys roll up for the period of time that they do, is it different for different individuals etc..
I recomend you observe the world pasivly until you notice something intersesting that leads you to ask a question. Then collect some data..
