We’re big fans of STEM activities and love trying STEM projects for elementary, STEM activities for kindergarten and everything in between. But when kids go back to school and the air starts to cool, it’s fall STEM activities that we’re interested in trying. This year, I created some fun fall STEM challenges that you can print out and use to make your STEM learning fall-themed!
These fall STEM projects will delight kids of all ages, but are particularly designed for kids in elementary school. Each easy STEM challenge for fall can be adapted to suit the learning needs and interest level of kids between the ages of 5 and 12.
When we put our fall STEM challenge cards into a jar and selected one at random to try, we pulled out the fall lava lamp card!

OUR FALL STEM PROJECT- FALL LAVA LAMP
For our fall STEM project we pulled out the lava lamp card.
For this project, we used vegetable oil, water, orange food coloring, a mason jar, and Alka-Seltzer tablets.
Fill the jar about 1/4 of the way with water and dye it orange.
Fill the jar the rest of the way with vegetable oil.
Drop in an Alka-Seltzer tab and watch the science happen!
THE SCIENCE BEHIND THE FALL LAVA LAMP
Alka-Seltzer contains baking soda and citric acid. When the tablet hits the water, a chemical reaction between the acid in the citric acid and the base in the baking soda causes carbon dioxide gas to form.
When this happens, the gas makes small bubbles in the water that rise to the surface of the jar because gas is lighter than water and oil.
But as the gas rises, it takes a small amount of the colored water with it, creating a lava-like effect as the bubbles travel through the oil layer, which slows their movement.
You can learn quite a bit with a lava lamp science project!
