First grade electrical engineers continued their study of circuits. In this lab, we learned how to use an insulator (clay) between conductive playdoh to prevent short circuits. Each pair of collaborative partners made a flashlight and an octopus. Can you identify the insulator in the circuits below? Next week, they will apply what they’ve learned to create original designs.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

At the end of lab, we added a propeller to the circuit. Why is there a difference in speed in the two circuits below?
