STEM Activity: Jar Terrariums



This fun activity was part of our mini-biology / earth sciences “unit” (so to speak). I found the activity here at Don’t Mess with Mama.  Here’s what you will need to make these lovely things in your home or group:

  • small gravel or pebbles (1/4 cup for pint sized jar)
  • activated charcoal (1/4 cup for pint sized jar)
  • potting soil (1/2 cup)
  • tools to position plants (chopsticks, tweezers) and a small spoon if your jar is really small
  • spray bottle with water

The supplies cost us about $2 per person, plus we had everyone bring their own jar or container to build their terrariums in. We set the supplies up assembly-line style, and had the kids do a scoop of each item before choosing the plant/s they wanted in their miniature garden. We also brought some little figures to decorate their finished product.

This was an excellent and inexpensive project to do to continue our biology unit. Hope you try it out! Send us pictures of your results!
