Description

"Observing the Growth of Mung Bean Sprouts" Biology and Environment PPT Courseware 3

Teaching goals and requirements

1. Name the main environmental conditions that affect plant growth and be able to give examples;

2. Be able to explain some of the changes that plants may undergo to adapt to the environment when the environment changes;

3. Design an experiment on whether mung bean sprouts need sunlight during their growth process; be able to explain the impact of the amount and direction of water on the growth of plant roots.

Do mung bean sprouts need sunlight to grow?

Mung bean sprouts do not need sunlight to germinate, but do they need sunlight to grow?

Design our experiment:

What is our problem?

Our guess?

What conditions should be the same?

What conditions should be different?

What is our experimental approach?

How to design the record sheet?

Experimental plan on the relationship between the growth of mung bean sprouts and sunlight

Our question is: Do mung bean sprouts need sunlight to grow?

Our guess: Mung bean sprouts need sunlight to grow.

The same conditions: water, air, temperature and germinated mung bean seeds

Different conditions: sunlight

Experimental method: Give the mung bean sprouts in the experimental group full sunlight, cover the mung bean sprouts in the control group with black plastic bags, but open a few small holes on the sides so that air can enter, and observe them for a period of time.

Water requirements for the growth of mung bean sprouts

The length of the mung bean sprout roots depends on the amount of water in the environment where the mung bean sprouts grow.

Why is this?

plants and environment

Plants need a certain environment to grow. When the environment changes, they will try to adapt to the changes in the environment.

think

Where do bananas, pine trees, and cacti live? And why?

What other examples do we know that illustrate the idea that plants should grow to suit their environment?
