Get your friends to help you act out gears with different ratios!

A great engineering experiment where students can build and test the strength of different bridges.

Test the strength of different construction techniques in this engineering experiment.

Experiment with using buttresses to strengthen walls.

In this investigation students experiment with diagonal bracing for strengthening stuctures.

In this Simple Machines science experiment your students are introduced to levers.

There are 3 different kinds of levers.  In this engineering science experiment you can build them and learn how they work.

A great hands on simple machines experiment about the simplest of all machines - an inclined plane.  Students will genuinely be able to see the difference an inclined plane makes to the amount of effort needed to raise a load and will be able to compare a long inclined plain with a shallow slope with a short, steep inclined plane.

While a winch is not often included in a list of simple machines, it is a great experiment to include in this unit as it starts a discussion about what simple machines are and how they help us.  A winch is part wheel and axle, part pulley, part lever!

I bet you never thought you could build your own clock, but you can, of sorts!  This version of a sand clock works in exactly the same way as traditional hour glasses and is a fun engineering experiment for your students.

In this very easy experiment your students will create rollers from pencils and investigate reducing friction.
