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

Part I: Communicating findings from experiments

1. How are my mung bean sprouts growing?

2. Why do everyone’s mung bean sprouts grow differently?

3. How can we make mung bean sprouts grow better?

4. What are the necessary conditions for the healthy growth of mung bean sprouts?

Necessary conditions for seed germination: temperature, moisture and air

Necessary conditions for the healthy growth of mung bean seedlings: temperature, moisture, air, soil, sunlight, etc.

Observing the growth of mung bean sprouts PPT, Part 2: Classroom experiment

Experiment 1: Do mung bean sprouts need sunlight to grow?

1. What conditions do we change? Which conditions should not be changed?

2. Do the two groups need the same amount of mung bean sprouts?

3. How can we know whether changing conditions has an impact on the growth of mung bean sprouts?

4. How to record? What should be written down?

Experiment 2: Water requirements for the growth of mung bean sprouts

Spread several layers of absorbent paper on a plate, place 5 newly sprouted mung beans side by side on the absorbent end, and keep one end of the absorbent paper moist.

1. What are the differences in the living environments of these five mung bean seeds?

2. What effects will different environments have on mung bean seeds?

3. Why do we speculate this way?

Observing the growth of mung bean sprouts PPT, part three: multiple choice questions:

1. The most basic conditions required for mung bean seeds to germinate are ( )

A. Certain moisture, suitable temperature and air

B. Light, moisture, temperature, air and soil

C.Light, moisture, temperature and air

2. In which direction will the mung bean sprouts grow? ( )

A. There is water directionality

B. Direction without water

C. The direction of growth has nothing to do with the presence or absence of water.

3. Place two groups of well-growing mung bean sprouts in the same greenhouse, and add an appropriate amount of water at the same time. Let one group receive light and the other group be covered with opaque things. The conditions changed in this experiment are ( )

A.Temperature B.Water C.Light

4. The leaves of cactus evolved into needles for ( )

A. Reduce the evaporation of water B. Protect yourself C. Both A and B are correct

5. The reason why seeds sown in the soil cannot germinate is ( )

A. The seeds are incomplete B. The soil is too dry C. All of the above are possible

6. During the experiment, put tissue paper in the box. The correct statement about the function of paper towels is ( )

A. Prevent the seeds from rolling B. Allow the seeds to obtain the appropriate amount of moisture C. The role of heat preservation
