"Exploring the Method of Life" PPT

Part One: Exploring the Impact of Light on the Life of Rat Women

It mainly relies on the moist body surface to breathe and relies on muscles and bristles to move.

On what surface do earthworms crawl quickly?

(1) Ask the question: On what surface do earthworms crawl quickly?

(2) Make a hypothesis: Earthworms crawl quickly on wet cardboard surfaces.

(3) Experiment: division of labor and cooperation, designing experiments

(4) Experimental conclusion: Earthworms crawl quickly on wet cardboard surfaces.

Methods of exploring life PPT, part 2: making assumptions

A hypothesis is a possible explanation for a problem. Although the hypothesis is not a fact, it is not a baseless conjecture either.

1. Assume that maggots come from rotting meat.

2. Assume that maggots are produced by flies.

3. Assume that maggots did not come from rotting meat.
