STEM Learning: Growing Egg and Cress Heads

Tasked with coming up with some interesting crafts and things to do with three children during the half term, I thought we’d start our week by making some egg and cress heads. I thought it would be interesting to watch them grow over the week. They’re easy to put together and all three had great fun making them and watching them grow over the week.

This activity is perfect for my 7 year old who is in Year 2. Cress grows incredibly quickly, and almost before your eyes. This fast growing crop was really exciting for the children to watch growing. Each day they found a new thing to be excited about. The best day was when they got to try eating the peppery cress, it’s a rare sight watching three children delightedly eating their greens!

STEM Learning: Growing Egg and Cress Heads

Growing egg and cress heads is a great opportunity for children to talk about their observations about how the seed grows into a plant and guessing what will happen next. It can also help to promote scientific thinking and helps with linking science to real life experiences.

How to make your egg and cress heads:
Hard boil your eggs and get a grown up to carefully take the top off and scoop out the egg inside.

Gently decorate your egg however you want. We drew pictures of cats and dogs on ours, but you could do almost anything.

Fluff up some cotton wool and put it inside the egg. Then pour some water over the cotton wool. Sprinkle some cress seeds on the top of the cotton wool and put on a windowsill in an egg cup.

Check the progress of your seeds every day, sprinkle more water on the seeds every so often. Within a week all of your seeds should have sprouted and your egg head should have a thick crop of cress hair!

  1. Inlove this idea! We’ve started growing some veg and herbs bit they’re growing quite slowly so the kids have lost interest. Dress is quick and my lot would love growing it in an egg she’ll. Thanks for sharing
