a meaningful experiment

Today, the teacher told us to go home and use the cup to do a small experiment: understand the germination of raw and cooked seeds.

After I went home, I discussed with my mother and decided to use the soy seeds to do this experiment.

After dinner, my mother prepared four seeds for me: two raw seeds, two cooked. I took two transparent glasses and went upstairs to put some sand in each cup, then put two raw seeds in one cup, two ripe seeds in another, and in the seed There was a thin layer of sand on it, and I poured a little water on each cup. After doing this, in order to distinguish between raw and mature seeds, I asked my mother to take two labels and indicate on them: raw seeds and cooked seeds, and put them on the outside of the corresponding cup.

Every day after school, I will go to see the seed, see if there is any germination, and record the observed situation in the diary. I hope that through this experiment, I can know whether the seeds are cooked and have no effect on seed germination.
