Grade 2 · Unit 1: Going outside

Caring for our environment

Small actions can keep our world clean.

Our shared home

People, plants and animals share the environment. What we do can help it or harm it.

Ponds give us water for fish, ducks and crops. Keeping them clean helps everyone.

Litter harms living things

Litter makes places dirty and ugly. Plastic bags can block drains and cause floods. Animals can eat plastic and get sick.

Plastic does not rot away. It can stay in rivers and seas for hundreds of years.

Dirty air and water

Smoke from cars and factories makes pollution. Dirty water in rivers harms fish and people.

Dirty air can make people cough and feel ill. Trees help by cleaning the air.

Reduce, reuse, recycle

Reduce: take a cloth bag to the market. Reuse: use a jar again to keep pencils. Recycle: old paper can become new paper.

Before you throw something away, ask: can I use less, use it again or recycle it?

What I learnt

• I know that litter and pollution harm the environment.
• I can say how to reduce, reuse and recycle.
• I know how people can care for the environment.
