 | How are ladybugs affected by insecticides? The purpose of this experiment was to determine the effect of insecticide on ladybugs. I became interested in this idea because I know that ladybugs are beneficial insects. They live around insect pests, which leads to accidental spraying of the ladybugs. Farmers need the ladybugs to help keep down pest population, and need to avoid killing them accidentally.

| What is the effect of light on a Crayfish? The purpose of this experiment was to determine if Crayfish are attracted to light or repelled by light. I became interested in this idea when I had Crayfish for a class pet in fourth grade, and didnít know weather to leave the lights on around them or to leave them in a dark area.

 | What does a barometer do? Make your own barometer to demonstrate how it can be used What is air pressure? Did you know you can make something that will measure air pressure? You can actually do a bit of weather predicting from a simple made-at-home piece of equipment. | ||

| What is "weathering"? Demonstrate how it happens to mountains When rocks are worn down by water, wind, or other means, that is weathering. Soil is made up of weathered rock particles, so without weathering, there would be no soil. Try the following activities to see how rocks can weather. | ||

| How to create an electrostatic charge using a handheld electrophorus A hand-held electrophorus can produce significant amounts of charge conveniently and repeatedly. It is operated by first frictionally charging a flat insulating plate called a "cake". In Volta's day, the cake was made of shellac/resin mixtures or a carnauba wax film deposited on glass. Nowadays, excellent substitutes are available. TeflonTM, though a bit expensive, is a good choice because it is a | ||

 | Does the particle size of sand used to make bricks matter? The purpose of this experiment was to determine which size of the sand particles used to make bricks would be the strongest. | ||

 | How do oil spills affect marine life? To demonstrate what happens in an oil spill, fill a glass bottle two-thirds full of water. Add blue food coloring to make the "ocean." | ||

| Do plants grow at different rates when given different plant foods? I wanted to know the growth difference in plants when different plant foods were being fed to them. I believed that if I used Miracle-Gro the plants would grow taller than the others, I believed this because Miracle-Gro seems to be the most popular nationally known plant food in the United States of America. I hoped that this investigation would tell me what plant food makes plants grow the fast | ||
