TN COMPONENT OF SCIENCE: Habits of Mind

TN GOAL:

To enable students to demonstrate ways of thinking and acting inherent on the practice of science; and to exhibit an awareness of the historical and cultural contributions to the enterprise of science.

3.5 SCIENCE AND TECHNOLOGY - Science and technology are separate but independent entities.

3.5a Science and technology change the environment in beneficial and detrimental ways

BENCHMARK: Developments in science and technology can improve our quality of life, yet may have a negative impact on the environment

TIME REQUIRED:

45 minutes

Tape player and tapes, poster board, magazines, glue, scissors

I am going to play the tape. I will play the tape very softly at first and then I will play the tape loudly. If the music hurts your ears, show me thumbs up. If it doesn't hurt your ears, show me thumbs down. Today we will learn about sounds that are harmful to the environment.

There are lots of things in our world that make noise. Some sounds are pleasant and we like to hear them. But some sounds are too loud and are harmful. A whisper is a soft sound. A fire truck horn makes a loud sound. (Teacher directs a group of students to talk to their neighbor, sing a song, make a sound like a fire truck, turn on the radio, television, or the tape player.) This is an example of sound pollution. Any one of these alone is acceptable, but not when all happen at one time. There is too much NOISE. Noise is a sound that is considered unpleasant. It may be too loud, too harsh, or just too much at once. It can also be harmful to your ears. Some machinery makes loud noises. The workers need to wear earplugs to protect their ears from these noises. Music that is too loud can also hurt your ears. The volume on earphones should not be turned up too high.

Let's look at our ABC chart. I want you to see if you can name one noise maker for each letter of the alphabet. (Lead the children through the alphabet naming noise makers. Write them on the board.) Let's go through our list again and this time show me thumbs down if the noise maker makes a harmful sound.

Turn to your neighbor and tell them an example of sound pollution. Have several children share. Point to the part of your body that is damaged by sound pollution.

Students work in groups to make a collage of noise makers. Cut pictures out of magazines. Some groups find pictures that make soft noises, other groups find pictures of loud noises.
