The Conscious Classroom

Simple, sustainable STEM ideas that reduce waste, spark curiosity, and inspire young minds.

Hi Reader,

Earth Day is tomorrow.

Need a last-minute activity that’s free, science-focused, and uses just a few things you already have at home or in your classroom?

Try this simple photosynthesis experiment.

All you need:
a leaf, water, a clear cup, a small rock, and sunlight.

That’s it.

Within minutes, kids can actually see photosynthesis happening—tiny oxygen bubbles forming on the leaf right in front of them.

I also created a free student printable to go along with this experiment—perfect if you want to turn it into a quick lesson or activity.

It’s one of the easiest ways to connect Earth Day to real science in a way that sticks. Because at the heart of it, Earth Day is about something pretty incredible: plants give us the oxygen we need to breathe.

It’s a small reminder of how connected we are to the natural world.

Let me know if you try this experiment!

Sustainably yours,

— Jessica

The Conscious Classroom Simple, sustainable STEM ideas that reduce waste, spark curiosity, and inspire young minds. Hi Reader, This week’s newsletter is all about seeing “waste” in a completely new way. I was paging through my son’s latest edition of The Week Junior magazine when I stumbled upon a fascinating article in the Science & Technology section. It was all about a company creating fiber from… wait for it… potatoes. Naturally, I had to learn more. A UK company called Fibe is...
