Could someone please look at following text for grammar mistakes and weird sentence, and add something, if they feel any need?
Activity
This week the students did an interesting activity about how to sow. All the children brought a jam-bottle, about 6 to 7 seeds, and some cotton with them. At first they filled the bottles with some water, and then capped them with some cotton. In the end they put the seeds on it. Throughout the whole week the students observed how the seeds germinated, as the rate of the experiment was quite slow.
Aim
The experimental activity aims at introducing the children to planting and germination, and helping them understand how they can preserve the environment from pollution, plus reinforcing their observation skills.

I hope I haven't changed your context too much.

Won't there be "the" before "week", i.e. Throughout (the) week?
Throughout the week....
