Is it possible to build a car out of cardboard, wooden rods, and rubber bands?  The Girlstart girls of Caraway Elementary proved it is possible by investigating the relationship between physical forces and mechanical energy.  Each group built a working car and some even discovered ways to make it travel longer.






Modeling the most effective design.

The girls from Gilbert Elementary traveled back into time and communicated with each other using international Morse Code! They created circuits using buzzers to learn about transferring electrical energy to sound energy. They learned how to receive and send messages using a switch they fastened onto their buzzer circuit. It was quite the chit-chat!



While trying to make their buzzer work, the girls realized a closed circuit is necessary in order for it to conduct electricity.
