"Seed Germination Experiment (2)" Biology and Environment PPT Courseware 4

Communication and reporting

1. I am doing an experiment on the requirements ( ) for mung bean seeds to germinate.

2. The germination status of my mung bean seeds is...

Organize statistics

Collect experimental information from the same experimental group and fill in the statistical table.

Experimental records of whether mung bean seeds need to germinate ( )

think:

(1) What information does the experiment bring us?

(2) Are the experimental results consistent with the guesses before the experiment? What does it mean?

(3) What are the necessary conditions for mung beans to germinate?

Basic conditions for seed germination

One is temperature. The lowest temperature for seed germination is 6-7°C, and normal germination can occur at 12-14°C. The optimal temperature is 20-25°C, and the highest is 35°C.

The second is moisture. Generally, it needs to absorb 120-140% of the water equivalent to the dry weight of the seed itself to germinate.

The third is sufficient oxygen.

Challenge tasks:

Planting mung bean sprouts

1. Plant mung bean sprouts in a flower pot, place them in a suitable place, and let the mung bean sprouts grow for a period of time.

3. Predict which conditions will affect the growth of mung bean sprouts.

4. Observe and record the growth of mung bean sprouts. (Workbook 3 sides)
