Germinating seeds in Petri dishes


This activity provides pupils with the opportunity to observe seeds germinating. Pupils will prepare seeds for germination and observe the process over a short period of time using simple equipment and are given the opportunity to use units of measure to compare seed germination. An ideal activity to consolidate numeracy skills.

This activity uses a method that was modified from a popular technique where a plastic water bottle is used to grow seedlings. You can see this for yourself here.


What examples of seedlings can I use for this activity?

As well as mustard seeds, you could use cress, pansy, radish or tomato.

Do I have to use Petri dishes?

No. Petri dishes have been tried and tested but you could use old plastic takeaway containers. You would need to ensure that whatever you decide to use it is transparent and that graph paper / acetate can be applied.
