Cool Green Ideas for Our Earth
How can we help our Earth? Look at these two cool ideas!
Idea 1: The "Energy" Playground
Can playing games make electricity? Yes! Some schools have a special playground. When students run, jump or play in it, the floor collects their energy. It turns this energy into power. We can use it to light our classrooms. This is a great way to save energy!
Idea 2: The "Eco" Brick(环保砖)
What can we do with plastic(塑料的) bags and bottles? We can follow the "3R" rules! First, we can recycle them. Just push(压) clean plastic bags hard into a bottle to make a strong brick. Then, we can reuse these bricks to build desks, chairs, and even small houses. This will help us reduce waste(浪费)!
