Connect a lead to the motor and the solar panel.
The motor goes around when there is sun on the solar panel.
See what part can be covered to slow down the motor but not stop it.
Outside works better than in a window. A lamp can be powered by sunlight.
There are over four volts generated by the solar panel.
One new battery is over 1.5 volts.
How many batteries does it take to match the solar panel?

The energy from the solar panel can be saved in a capacitor then it can be used to move a wheel.
Or a wheel can be turned to store energy in the capacitor.
Full power is indicated by the red light.
The energy from the capacitor can run the motors for a very long time.
She did a project on electricity.
Now they are building projects that can run on the saved up electricity.
