•Two treatments that you think help the seeds to sprout.•Two treatments that you think prevent or are not so good for the seeds to sprout.

1rst weekWe check how many seeds have sprouted in

each treatment and we measure the lenght of the sprouts.

We write down the treatments in 4 different charts ad take a picture of the results.

• Continue the treatments that were Ok and change the ones that went wrong.

ConclusionsGermination is the process by which seeds sprout. When seeds are ready to be planted, warmth,

water, and oxygen are all needed for a seed to germinate.

The seed contains the plant embryo, which stores enough food to give the baby plant all the energy it needs to sprout.

After the seeds sprout and use up all the stored food, they do need light to grow. The light is needed for photosynthesis, which provides the plant’s food source.
