What Levee Construction Holds the Most Force?
Grade Level: 4 thru 9
Category: Physics
Awards Won: 3rd Place, 8th Physical Science, ACSI Science Fair
Hypothesis: Levees constructed of rock will probably hold the most force because rock is strong.
Primary Materials Used: Fine Particle Dirt, Play Sand, 2.5 Centimeter Rocks, Wood, Nails, Shot Put Ball, Ruler
Details: Click Here to see the complete free science fair project "What Levee Construction Holds the Most Force?" By using different combinations of rocks, sand and dirt, several different levees were built, each exactly the same size. The strength of each levee was tested by rolling a shot put down a ramp and recording the number of times it took to break through the levee.

This project is literally dirt cheap to do, easy to create and yet the results are very interesting!
