K'NEX Education Levers and Pulleys Set - Sailboat, Block & Tackle and Flagpole models

We had two 3rd grade classes in the library for 45 minutes. They worked in groups of two and three. Half of the groups worked on the Sailboat model, while the other half worked on the Block & Tackle model. The students enjoyed the activity and were engaged the entire time. We learned that these models were too complex to complete in 45 minutes. We had the remaining classes build the Flagpole model. The simpler design allowed students to complete the activity and demonstrate the mechanics of a pulley system.
