I love easy experiments that make science cool! This rainbow colored celery experiment is simple to set up and really makes transpiration come alive for kids.
Celery Science Experiment
- celery (the leafy parts show the color the best)
- jars
- water
- food coloring
We have been doing a lot of rainbow activities lately so we made our water rainbow colored by mixing colors. It was a fun way to extend the learning for my preschooler, but you can use any colors you want.
The kids put the celery in the colored water and then recorded their observations in their science notebooks. This helps to encourage them to think like scientists and helps them track the changes.
We left the celery in the colored water overnight and saw that the stems and the leaves of the celery started to turn the same color as the water that it was in.
This is the process of transpiration. The xylem in the plant suck up water like a straw and the colored water moves throughout the celery. The cool thing about this experiment is that you can actually see the capillaries once they are colored.
The kids recorded their observations and we noticed that the celery stalks with more leaves “drank” more of the water than the ones with less. We concluded this was because the leaves needed water too.

This is an awesome one for kiddos!! Evan is actually did this yesterday for his science fair project!
How FUN!!! Go Evan!
Ya in 1-2 minuts it starts to cange color
Love this science experiment. Can’t wait to try this at home!! Thanks so much for including us in your list of other experiments!
Yay! Thanks Katie!
ok you do good girl
Valerie–Don’t you remember doing this in 2nd grade bc I remember teaching it.
My kids would love this! Such a simple but fun and educational project to do with them. We just got some celery, too, so this is perfect. Thanks for sharing. 🙂
Yay! It is so cool to see the colored xylem in the celery! I hope they love it!
Perfect! I have celery in the fridge that is getting wimpy… I think it’s time for some science!
Pinned it!
That’s perfect!
I just wanted to mention a misconception that might be best to clarify. This is not actually an example of transpiration. It is an example of capillary action in which the water molecules travel up the tiny ‘capillaries’ against gravity because of waters unique bonding properties. Transpiration is when plants give off water back into the atmosphere.
Helpful explaination!
Actually, complete transpiration happens when both ideas are put together. It is the water moving through the roots, up into the plant and then being released into the atmosphere.
Thank you!!! I was about to comment this as well.
