Introduction to Solid Waste

Age group: 6-15

This page provides you with a snapshot of this activity that allows students to learn about the different types of batteries that power of every day lives. You can find batteries almost everywhere. They help us speak on the phone, get us places on bikes and in cars, and give us light when the power is off. Because batteries are so widely used and do not last forever, many batteries are thrown away. Batteries contain heavy metals like lead, mercury, nickel and cadmium which are dangerous to the environment. This is why we need to take special care when we have finished using them. Spot everyday items that use batteries and colour them in, while learning about the different types of batteries and how you can make conscious changes to save the environment from pollution.

We recommend that you use the ‘Introduction to Solid Waste’ activity before any of the other activities as it is a good starting point for students to learn about waste and provides a comprehensive overview of how waste is generated and its impacts on animals, the environment and us.
