A Clean Environment | Science Lessons for Grade 4 Students

What does environment mean? Environment means the surroundings in which a person, animal, or plant lives. In the case of a human being, the environment can be his surroundings such as the classroom, school, home, office or the town in which he lives. It also means the nature around us, water and air, and the earth itself. In a dirty environment, it is very easy to catch diseases, so it is imperative that one lives in a clean environment.

A school is very important to any child because he spends a great amount of time there. Let us look at how we can keep the school and the classroom clean.

What are the other ways to keep your school clean?

  • Do not spill food in the corridors or in the classroom. If any is spilled, clean up immediately.

What are the ways in which we can keep our surroundings clean?

Our surroundings mean the nature around us. It can include the parks and beaches we go to, the roads and walkways that we use etc. It also refers to the rivers and oceans.

Some people throw rubbish anywhere they like. This is littering. It is because of littering that our rivers are so dirty. The wind and water can also wash rubbish from the land into rivers and seas. This negatively affects the animals and plants that live there. Do you know that 9 billion tons of litter end up in the ocean every year? About 70% of this sinks straight to the bottom. Ocean-dwelling animals are incapable of distinguishing between trash and food. Therefore it is estimated that around 100,000 marine mammals die each year either by ingesting litter or getting entangled in it.

There are many ways in which students can help reduce littering. First of all, throw rubbish in the proper place, which is the rubbish bin. Do not litter in the rivers and oceans. In schools, you can have a beach cleaning campaign.

You may be surprised to know that the most common object found during litter clean-up is fast food litter. What you can do is to reduce your consumption of fast food because much of it comes in single use plastic.
