Today we learned about levers, wheel and axle, and belts and pulleys. This section of the course is very heavy in theory so some of the children don’t like to listen however it is crucial that they do so. We discussed the three different classes of levers, and pulley ratios. We will be continuing with simple machines next week as well before moving onto a more complex build. Please ask the students to take apart their kits completely and put the components into the right sections we’ve had several instances of this not happening and as such I had to repair a box latch. Additionally I am finding a lot of pieces on the floor after each class, as such I ask that the parents help make sure the kids clean up after themselves.
