In the noise pollution recording experiment, kids will learn that noise is one type of pollution that is often overlooked. Use this simple activity to focus on the noise around you -- and maybe cut out some pollution, too.
What You'll Need:
- Tape recorder (optional)
Step 1: Walk around your neighborhood and listen for as many sounds as possible: cars, trucks, birds, dogs, lawn mowers, and all other noises.
Step 2: Think about how many of these sounds you normally notice. How many do you usually ignore? You may be so used to the noises that you don't notice them anymore.
Step 3: If you have a tape recorder, take it with you as you listen. Record as many sounds as you can find.
Step 4: Make recordings of any sounds that you consider noise pollution. Is your neighborhood too loud?
Step 5: Think about the types of noises that bothered you the most. Then decide what you can do about them. The best place to start is at home, with the noises that your own household produces.
Some communities have banned leaf blowers because they are too noisy and cause pollution. If you have a leaf blower, consider using a broom to clean your sidewalks and a rake to collect leaves from your yard. It takes about the same time and doesn't take that much effort.
Gas-powered lawn mowers are also very noisy. Some people use push mowers instead -- and get their exercise while they mow!
Talk to your neighbors about ways you are reducing noise pollution. Maybe they'll follow your example.
