what are some cool science experiments?

Question

i am trying to get a head start on the science fair in the summer and i want to do a cool experiment.

Answer 1

It's kind of pricey, but I came across something called the Hydrodynamic building set. It looks like a lot of fun, and you can learn about fluid dynamics which is pretty cool, and you probably be a good subject that's unique and stands out. The only problem is it's about $90. Maybe you could come up with something in the same vein. A subject other than the same old boring things, making a vinegar and baking soda volcano, etc.

Some interesting fields that come into my head that would probably be fairly easy and fun are:
jet propulsion
energy transformation
electro-magnetics
*fluid magnetics* super fun.
if you have time, how about plant trophisms. (such as phototrophism and gravitrophism.)
*non-newtonian fluids*

Slightly harder would be:
quantum physics investigation
fluid dynamics
sub atomic particles

good luck

Answer 2

Well, the old baking soda/vinegar volcano is always good.

Also, there was one I did in high school where we pulverized some Total cereal and then mix it with water then took a magnet through it. The point was to illustrate that the magnetic iron in the cereal can't be used by the body so Total's claim to having lots of iron in the cereal is kinda bogus.

Burning a peanut under a small beaker of water to heat it up a little bit it illustrates calories and how much energy a peanut actually has in it. It can heat the water several degrees.

I don't know how advanced you are but if you have the resources there's a good experiment involving synthesizing aspirin if you can get the right things.

Google science experiments and see what you get.


The volcano can utilize the scientific method if you approach it from an acid-base interaction standpoint. Plus it doesn't have to be a literal volcano....when you mix those together it just might as well be.

Answer 3

Whatever you do, make sure it uses the scientific method. That means you have to make an educated statement, called a hypothesis, then design an experiment that tests that statement, then report your findings. So if you just mix baking soda and vinegar and make a model of a volcano, you're not really using the scientific method.

You could determine which wavelengths of visible light (colors) are most absorbed by plants. Look up the wavelength of light in various colors, red is 620–750 nanometers, for example. Do some research and hypothesize which colors are absorbed and which are reflected by plants.

Sprout some bean plants outside, then, just after they've sprouted, put plastic wrap of various colors above them to filter the sunlight. The plant that grows the most over a certain period of time absorbed the most light. The best way to measure growth would be to weigh the plants after digging them up and washing the soil off them, but height or number of leaves would probably work as well. Compare the plants that grew under various colored plastic wrap to plants grown in natural sunlight.
