Description

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

Part I: Organizing and analyzing experimental information

Have the mung bean seeds we planted sprouted? What about mung bean seeds from other groups?

Collect experimental information from groups doing the same experiment and analyze it together.

What is the difference between the data for the experimental group and the control group?

Can we draw conclusions from the experimental data?

Are the experimental conclusions consistent with our pre-experiment guesses?

Seed germination experiment PPT, part 2: communicating experimental information

Listen carefully to groups doing different experiments describing their experimental methods and the information they obtained.

Communicate with students in other groups to learn about their findings and how they use the data in the experiment to explain the experimental results.

Are their experimental results consistent with their pre-experimental predictions?

Seeds generally need to absorb 120-140% of the dry weight of the seeds before they can germinate.

Seed germination also requires sufficient oxygen.

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

Seed germination experiment PPT, part three: planting mung bean sprouts

Plant the mung bean seeds that have sprouted in the experiment into a flower pot, place them in a suitable place, and let the mung bean sprouts grow for a period of time.

Planting Instructions:

1. Fill the pot with soil to 1/3, and use tools to take out the sprouted mung beans from the planting box (cup), being careful not to damage the roots.

2. Gently loosen the soil in the flower pot, place the mung bean sprouts in the middle of the flower pot, add the soil in the flower pot to two or three centimeters away from the mouth of the flower pot, and gently press the soil around the mung bean sprouts.

3. Water the flower pot thoroughly until the water flows out of the drainage hole, and then place the flower pot on the balcony.
