Description

This lesson is about gears (translation of the space 'Tandwielen Ontdekken'). By helping Stef to design his bicycle, you will learn which side gears turn and how you can use them to accelerate.

The lesson starts with an introduction of Stef's bicycle. Thereafter, hypotheses (expectations) will be created. The hypotheses will be tested in an online lab in which you can draw gears. Finally, it will be concluded that gears turn in opposite direction when they are placed directly to each other, but in the same direction when they are connected by a chain. The other conclusions is that you can use a combination of large and small gears to accelerate. These conclusions will be used to give Stef advice.

This online lesson was translated from Dutch with the help of Evelien Mulder.
