Description

"The Choice of Earthworms" Biology and Environment PPT Courseware 3

teaching objectives

1. Experience the experimental design and discussion of what kind of environment earthworms choose to live in.

2. Observe the demonstration experiment of what kind of environment earthworms choose to live in, and explain it.

3. Can explain the certain environmental conditions required for animal life.

Earthworms and the environment

Discuss in groups and design our experiment:

Do earthworms prefer dark environments or bright environments?

Do earthworms prefer humid or dry environments?

Experimental design one

Our research question: Do earthworms like to live in a bright or dark environment?

Our guess: I think earthworms like to live in dark environments

Experiment preparation (materials): long box, earthworms, lights

Experimental method: Place the earthworms in the middle of a long box, let one end of the box be illuminated and the other end remain dark. After a few minutes, open the box and see which end the earthworms have gone to. Repeat several times.

Experimental design two

Our research question: Do earthworms like to live in humid or dry environments?

Our guess: I think earthworms like to live in humid environments.

Experiment preparation (materials): earthworms, strip box, water, soil

Experimental method: Put the earthworms in the middle of a long box, let one end of the box dry and the other end stay moist. After a few minutes, open the box and see which end the earthworms went to. Repeat several times.

summary

Like earthworms, various animals like to live in certain environments, and different animals have different needs for the environment.
