This ILS can be used as an introduction of “Machines and mechanisms” with 12 – 13 year old students. Videos capture the attention of the students; hypotheses make them think about the relationship between sizes, and rotation speed, about the way gear trains are connected and how they spin. Also gear sketch lab allows them to build gear trains and check their hypotheses.

Finally they upload their work and discuss what they have learnt in the classroom.
