Today we used what we learned yesterday about construction and friction in our projects. After doing some activities to learn more about gears and pulleys, we put everything together with a device which spins one or more of the figures (LEGO people). Once this task was complete, the campers used their knowledge of gears and pulleys along with a motor to construct a solar powered vehicle. (Thank goodness for sunny weather!) Then we used solar panels to power a trolley car that traveled along a suspended string. Today we began to see the emerging creativity in construction of devices and vehicles along with excellent team work.
