Third Grade Is Catapulting Away!

In 3-205E we are continuing to study motion, mechanical energy, and simple machines.  We learned about kinetic energy and potential energy in various ways.  To culminate these studies, in teams, we worked to built tiny catapults.  We had to show that our catapult had both kinetic and potential energy.  We made a plan before building of how we could show both forms of energy, as well as how to make sure we launched accurately and for distance.  Then it came time to build.  We chose from various materials and worked together to build an accurate catapult.  We tried it out, modeling the two forms of energy, and launched candy chicks to try out our teams accuracy and distance.
