Distance to the moon
This is a student practical activity that allows students to use the concept of ratios to determine an experimental value for the distance to the moon.
This activity also introduces the idea of sources of experimental error.
It is necessary for the moon to be visible in the sky for students to obtain their measurements. The calculations can be done anytime afterwards.
Note: The measurements should be made with the moon high in the sky to prevent refraction due to the Earth's atmosphere giving an incorrect result due to the moon appearing larger than it really is.
