More Student Science Project Ideas

Dear Dr. Shawn,

I did a project on oil pollution in the water. We all know that lots of oil gets spilled into the water each year but no effective method for cleaning it up has surfaced. So I took put water in a few containers and poured motor oil into them. I used the heaviest grade. Then I chose three ways to try to remove the oil from the water. I used a spoon (scooping), cheesecloth (straining), and sand to see if I could make the oil sink to the bottom, combine with the sand and make to easy to scoop or vacuum out. You can use any methods you want though. The great thing about this project is that it applies to real life and will therefore be easy to find connections of how to use this. I did this in 7th grade and got an A!

Dear Dr. Shawn,

My idea is "How fast does temperature affect mold growth?"

Mold is dark spongy patches that sometimes appear on bread. My project was to put one slice of bread in two sandwich bags. I put a little warm water in each of them. I put one in a warm place (above the stove) and one in a cold place (the fride). When I took them out 6 days later, the sandwich in the cool spot looked fine while the sandwich in the warm spot had dark patches of mold.

Dear Dr. Shawn

I got 2nd place with this project!

Question: Does temperature effect the way a musical instrument sounds?

You need a tuner (machine used for finding out what note your instument is playing), a flute, and a violin (you can use any other instrument), and a thermometer. Play your instruments in room temperature seeing and recording the temperature, date and the tune theyre in (make sure you remember the note you played). At night when its cold out put the thermometer and instruments outside all nite, in the morning go out and play the same note, again recording the tune, date, and temperature. then put a hairdrier in a small room, put the thermometer and instrument in the room and turn on the hair drier, close the door and keep it closed for about 3-4 hours. After that go back into the room & close the door turn off the hairdrier and play the instruments recording the time, date and tune.

Repeat this about 6 times.

Dear Dr. Shawn,

In the fifth grade I got second place with this topic.

Is the reach of a magnet affected more by cardboard, glass, or plastic. Place a sheet of one of these materials between the magent and a magnetic weight. Find out how thick the material has to be before the magnet is not strong enough to hold it any longer. Plot this on a bar graph and compare the results. The less thickness you need to break the magnet's hold on an object, the more strongly that material affects the magnetic field.

i am in desperate need to find an experiment within 2 weeks. i am ordered to do an experiment that invovles , the different kinds of diseases that can occur within our body. for instance, i initialy chose to do a research based on the chimera syndrome: when a person inhabits two different dna; one located in the body cells and another kind in the plasma cells. i was to no avail able to come up with an experiment of such magnitude. i was hoping you may have an idea on what kind of human- related diseases that i may experiment on.

I think that the BBC are right on this.
