Caring for Our Environment · Semester 2

Waste Management and Circular Economy

Examining Singapore's comprehensive waste management strategies, including incineration, landfill, and the transition towards a circular economy model.

About This Topic

The Problem with Litter focuses on the negative impact of waste on our environment, wildlife, and public health. Students learn how litter can clog drains (leading to floods), harm animals (who might eat it or get tangled in it), and make our shared spaces unpleasant. The topic emphasizes that littering is a choice that affects the whole community.

This topic is a key part of the MOE Social Studies and Character and Citizenship Education (CCE) curriculum. It aims to build a sense of social responsibility and environmental ethics. Students grasp this concept faster through 'cause and effect' simulations and by investigating the journey of a piece of litter from the street to the sea.

Active Learning Ideas

Simulation Game: The Clogged Drain

Use a model of a drain (or a tray with a hole). Students add 'litter' (bits of paper/plastic) and then 'rain' (water). They observe how the litter blocks the water and discuss how this causes floods in our streets.

Inquiry Circle: Litter and Wildlife

In small groups, students look at photos of animals affected by litter (e.g., a bird with a plastic ring). They discuss how the litter got there and what could have been done differently to keep the animal safe.

Think-Pair-Share: Why Do People Litter?

Students think about why someone might throw rubbish on the ground even when there is a bin nearby. They share with a partner and then brainstorm three ways to encourage people to use the bin instead.

Watch Out for These Misconceptions

Common Misconception

Students might think that 'small' litter, like a sweet wrapper, doesn't matter.

What to Teach Instead

Teachers can use a 'Pile Up' demonstration: if every student in the school throws one wrapper, how big is the pile? This helps students see that many small actions add up to a big problem.

Common Misconception

Students may believe that litter only stays on the ground where it was dropped.

What to Teach Instead

Through a 'Journey of Litter' map, teachers can show how wind and rain carry litter into drains and eventually to the ocean. This surfaces the idea of interconnectedness in the environment.

Frequently Asked Questions

Why is littering a problem in Singapore?

Littering makes our beautiful city look messy and can attract pests like rats and cockroaches. It can also block our drains and cause flooding during heavy rain. Most importantly, it can harm our wildlife and pollute our waters, which is bad for everyone.

What happens if I get caught littering?

In Singapore, there are strict laws against littering to keep our city clean. People who litter can be fined or even asked to do 'Corrective Work Order' (CWO), where they have to spend time cleaning public areas to learn why it's important not to litter.

How can active learning help students understand the impact of litter?

Active learning, like the 'Clogged Drain' simulation, provides a visual and practical demonstration of a complex problem. When students see the 'flood' happen because of the 'litter' they added, the lesson becomes much more memorable than just being told that littering is bad. This 'hands-on' cause-and-effect experience helps them internalize the responsibility of keeping their environment clean.

How can I help stop littering?

The best way is to always lead by example and put your own rubbish in the bin. You can also remind your friends and family politely to do the same. If you see litter on the ground and it is safe to do so, you can pick it up and put it in the nearest bin.
