Growing Balloons

Balloon Greenhouse | Activity | Education.com.

I found this on pinterest and am so intrigued to see how well this works. Ellen, the author, suggests using radish seeds, but I’m wondering if in a STEM environment it might be more useful and cost effective to use cress seeds. We’ll have to try it out with that.

I love the fact that you tie off and make a contained “world” within the balloon. I can imagine asking a group what a plant needs to grow and then asking them if the seeds have all of that inside of the balloon.

I also love the idea of also growing the plant outside of the balloon, to see how the balloon affects the growth.

Could this also work on a larger scale to demo phototropism? Paint the balloon all over, or on one side. Or just use a dark coloured balloon.

I seriously cannot wait to try this!

And of course, this experiment is perfectly suited to be done at home – that’s what Ellen did. We’re just going to adapt it for inside of education. Or try to!
