Legos - goal kicker

'Goal Kicker' was fun!
I like how it kicked!

I programmed the legos to move.
The computer runs the program and sends it through the wire to the motor.
That is electrical energy.
When the motor turns and moves the leg and kicks the ball, 
that is called mechanical energy.

Then I guessed how far the kicker would kick the ball. 
It wasn't very far at first.
I found that a bigger ball did better.
 I even made a bull's eye! 
woohoo!!!
