Physical Science Ideas

Use a spectroscope to analyze the light spectra produced by burning different elements. Do you expect compounds that contain some of the same elements to have similar spectra?

Build your own light bulb, and then experiment with what materials make the longest-lasting or brightest filament.
E
xperiment with the most effective materials and design for propellers or model airplanes.

What kind of substance (metal, ceramic) conducts heat the best? Do a thermal conductivity study to discover which substance works best for a pot handle and which works best for a teapot.

Find out how increased mass affects velocity and acceleration by doing a project with dynamic carts. You can also experiment with the resulting velocities after a collision between a moving object and unmoving one, or between two objects moving in opposite directions.

Experiment with the best way to build a solar oven to cook your own food.

Chemistry Ideas

Try distilling drinkable water from salt water using the sun. What materials can you use to speed up the rate of evaporation?

Make your own ink using different substances and compare how each withstands the effects of heat, light, or moisture. For example, does one type fade faster than another when they are heated or when exposed to strong light?

Use pennies to copper-plate an iron nail. See if pennies minted before 1982 (when they were 95% copper) make a thicker coating than newer pennies do (they only have 2.5% copper).

How does the number of pennies you use affect the time it takes to plate the nail?

Use a semi-permeable membrane to experiment with osmosis. What kinds of substances pass through the membrane, and what substances don’t? What is a common property that prevents substances from passing through the membrane?

Which retains heat longer, salt water or fresh water? Design an experiment to find out.

There's a PBS show called Dragonfly TV. It's all about kids performing scientifc experiments. I'll bet they have plenty of good ideas. http://pbskids.org/dragonflytv/.

Also, check out the Mythbusters website - they do quite a few simple experiements. http://dsc.discovery.com/fansites/mythbusters/mythbusters.html

Good luck!

My personal favorite is boiling water in a paper cup. You must write about boiling point of water and the flash point of paper.

Give it a try....at least it is fun. I even used to cook spaghetti.

Make sure you keep the cup full. :)
