Moon Rover – Building a solar powered rover

Brief description:

In this activity, students will compare the advantages and disadvantages of renewable energy sources and non-renewable energy sources and study simple electrical circuits.

Using the Moon as context, students will build a small motor and a solar cell. They will also identify the main features their rover must have in order to go to the Moon, and improve their inital rover design.

Subject: Science, Physics, Technology, Arts

Activity 1: Powering a Lunar Rover

In this activity, students learn about the advantages and disadvantages of renewable sources of energy. They will learn about the Moon environment and consider which is the best power source for a lunar rover. The students will also sketch simple electrical circuits.

Equipment

Student worksheet printed for each pupil.

Pen/pencil

Activity 2: Build a Solar-powered Rover

In this activity, pupils will build a solar-powered rover using a solar cell, a motor, and craft supplies.

Equipment

Hot glue

Double-sided adhesive tape (optional)

Additional craft materials for decoration

Did you know?

A Moon rover will have to be designed to travel to unfamiliar rocky terrain, covered with regolith and with unkown slopes. The rover should have specially designed wheels that can overcome these conditions wihtout having any problems. It will also have to carry scientific instruments such as cameras and drills to take samples. The rover should also have autonomy and power to cover long distances.
