For this experiment you will need an egg, a glass bottle with a mouth a little narrower than the size of the egg and matches. Hard-boil the egg; once it cools peel the shell. Place the bottle upright on a table or counter. Light three matches and put them in the bottle simultaneously. Place the egg on the mouth of the bottle.
Materials needed to complete this experiment include a limestone rock, a bowl and an acidic liquid like vinegar, lemon juice or cola. Place the rock in the bowl and pour in your acidic liquid. Let it sit for three days and then record your results. You can also make adjustments to the experiment by changing the type of rock and acidic liquid, and then compare your results.
You will need liquid soap, water, corn oil, a toothbrush and a feather for this experiment. Create a chart with three rows and three columns. Label the columns "Absorbed," "Repelled" and "Changes," and the rows "Water," "Oil" and "Soap." Dip the feather in the water and then in the oil, and record the results. Wash the feather with a toothbrush and liquid soap and record the results.
Materials for this experiment include three of the same type of plant; three boxes or cabinets to use as test rooms; three different light sources, which will be mounted inside the test rooms; and three light bulbs, one each of 25 watts, 60 watts and 100 watts. Put one plant and one light in each box or cabinet. Each box must be properly ventilated, and the light should be fixed on the side of the box but not close enough to burn the plant. Water and inspect the plants for 10 days. Record your results.
