Make a motorized working model to sow how Solar and lunar eclipse occur. 

Assembly instructions are inside the kit

Useful for age 10+

You will need 2 AA type pencil cells - They are not included in the kit

The model has a tilted Earth in the middle. Moon is orbiting the earth around its equator. Sun (torch) is to be places away from this model. One can adjust Moon position by moving it up and down, so that its shadow is not cast on the earth. This will explain why eclipses do not occur during every orbit. You can explain this natural pehnomena with this model
