PROBLEM: Does more magnification increase solar energy?

PREDICTION:   

PROCEDURE: Put a leaf on aluminum foil. Try and burn the leaf using 1, 2 and 3 lenses. (If you burn a leaf put it out immediately.) Your teacher will give you instructions how to perform this experiment outside. Describe how long it takes for the leaf to begin to burn. (Count: 1 thousand 1, 1 thousand 2).

 

DESCRIBE WHAT HAPPENS TO YOUR LEAF

1 LENS

 

 

 

 

2 LENS

 

 

 

 

3 LENS

 

 

 

 

Put your finger on the Fickle Foam and describe what happens.

 

CONCLUSION: Can you control the use of solar energy?
