Learners build a lever and use it to lift a load. With the load on one end of the ruler, learners add coins to the effort cup at the other end until the load is lifted.

In this physics activity, learners experiment with pulleys and find that they can decrease the effort needed when using a pulley to lift or move different loads.

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.
