When you think of a pyramid, you probably most often think of the pyramids in Egypt that are the resting places of many of the Pharaohs. There are many different ideas for science projects that students can do using the pyramids. Students can answer questions about how strong the structure of a pyramid is, how to build a pyramid and if pyramids really do have special power for growing and preserving plants.

## Strength of Pyramids

Test the strength of a pyramid. Build a pyramid using wooden blocks and wood glue. Place the blocks so that they form a pyramid with a point at the top. Allow the glue to dry completely. Fill sandwich bags with regular play sand. Test the strength of the pyramid by setting one sandbag at a time on top of the pyramid. See how many bags you can set on top of the pyramid without the pyramid breaking. Use some heavier items if necessary. You could even cut a square in a board that fits over top of the pyramid (make sure to have a parent help you). Stack evenly weighted items on the sides of the board and see how much weight the pyramid can hold. Make sure to weigh any of the items you place on top of the pyramid. This project works well for middle school age students.

## Build a Pyramid

Allow your first and second grader to attempt this project. A student can build an Egyptian pyramid. Buy some sugar cubes and some glue. You might want to get a cardboard base to set your pyramid on. The child needs to figure out the best way to build a pyramid. It might require some trial and error on his part. The student should figure out the idea of building a strong base to build a strong building. Do not tell him, but the base should be a square, such as 10 cubes by 10 cubes. Each subsequent layer of sugar cubes will be one less; such as layer two will be nine cubes by nine cubes, etc. After building the pyramid, he can paint the pyramid with paints that represent the colour of the pyramids.

## Pyramid Power

Perform an experiment to see if plants grow better under a pyramid. This project requires some research, which makes it more appropriate for high school students. Research the theories of pyramid power. Build your own pyramid using plexiglas. You need to cut plexiglas with a saw, so make sure to have adult supervision when performing this part of the experiment. You can also buy these at science supply stores. Plant some seeds and place them under the pyramids. Make sure to have a control group of seeds that are not under the pyramid. Take notes of when you water, but make sure to water both groups at the same time. Find out which plants grow better.
