Christmas Flowers – Transpiration Activity

We’ve done a few transpiration activities before, and if you followed our Spectacular Summer Science  series you might remember I struggled to get the flowers to change colour with natural food colourings. I was so disappointed as this activity is such a great way to learn about transpiration.

The lovely Lindy from Squidgyboo came to my rescue, bringing me some non natural food colouring back from America. It worked a treat!

What do you think of our Christmassy Carnations?

  1. Make sure your flowers are healthy and in an early budding state to ensure saturation. Other general tips are to ensure hydration and trim the stem a bit during the process.

    Also consider dying colored flowers or composing your own dyes for interesting results.
