In the mind lab kenza from the MOTAT helped us make electric cars we used motors and battery packs as the engine for the car and we also use some scrap pieces of cardboard for the body of the car and we also used skewers to hold up the wheels. when we were making the wheels we had to test that the wheels spun freely so that when we made our car it would move around.
Flash Lights
when we finished making our cars we then had to make a flash light using motor cogs and connective building parts. we were given a LED light and we had to use the motor so that it would turn of but there was a little cog that you had to spin and you had to spin it very fast just for a little flash of light.
