Cress growing investigation

Welcome to our Cress Growing Investigation page! 

Here we will add daily photos of the growing progress of our cress seeds - the pot growing inside in the warmth, and the pot growing outside where it's cooler.

Will one grow faster than the other? Which one will best fill my sandwich by the end of the week?!

What do you conclude from this investigation? Which pot of cress seeds grew the fastest? What was it that helped them to grow faster compared to the other pot? 


The pot of cress growing inside had a constant warm temperature. Despite it being warm outside during the day, the temperature at night dropped and was cold for those outside growing seeds. The coldness slowed down the life processes of the seeds, so they were slower to grow than the pot of seeds growing inside. 


In conclusion, the cress seeds grew faster and more healthily in the warmth - temperature has an important role in the growing of plants! I think I will carry on growing the outside seeds inside now to ensure we have more delicious sandwiches sooner rather than later! 


Yummy! 1
