of valves. This relates to the concept of automation and how mechanical
control systems work in real-life machines.

Observations

In the IC Engine Valve Model activity, students will observe how the model
simulates the function of engine valves. They will notice that the movement

of the valves is controlled by mechanical components powered by the battery.
This activity provides an understanding of how engines work, highlighting the
role of valves in controlling the fuel and air mixture in combustion.
