Treatments

• 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.

9
1rst week

• We 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.

Conclusions

• Germination 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
  plants food source.

Questions
