When you think of Easter, what do you think of?
I think of bunnies, eggs, carrots, and Easter science experiments for kids!
You might not think of Easter STEM activities as one of the staples of Easter, but hang out with us for a few weeks and you’ll start to come around.
This week, we made an Easter lava lamp science experiment and it was so much fun! This Easter twist on the classic lava lamp science project was super cute and the kids absolutely loved it. If you haven’t tried making an Easter lava lamp yet, make this your year! It’s such a fun and simple addition to Easter science activities.

WHAT ARE EASTER SCIENCE EXPERIMENTS?
Science experiments can get a bit boring if you do them over and over again. But if you bring in seasonal elements for each holiday, then even common science experiments become fresh again. With Easter science experiments, kids are learning scientific concepts and expanding their knowledge of science, but the use of Easter themes keeps these experiments fresh and fun.

WHY DO EASTER SCIENCE EXPERIMENTS?
I like to do Easter science experiments because my kids love using seasonal themes in their science experiments. Adding a seasonal twist to any science experiment keeps it fresh, and you can focus on learning a new element of the science experiment when doing it multiple times. Maybe the first time you focus on chemical reactions, but the next time you do the Easter lava lamp science experiment you focus on acids and bases. There is always more to learn with every science experiment!

WHAT DO KIDS LEARN WITH THE LAVA LAMP SCIENCE EXPERIMENT?
When you make an Easter lava lamp, kids can learn a lot!
A lava lamp made with Alka-Seltzer tablets is a lesson in chemical reactions. Alka-Seltzer contains citric acid and baking soda, which react together when added to water. This reaction creates carbon dioxide gas, which travels to the surface of the oil. The colored water gets carried up with the gas, making the jar bubble with colored lava lamp bubbles!
Use our science experiment worksheet to guide kids through the scientific method when completing this activity.

EASTER LAVA LAMP STEM ELEMENTS
Science: Learn about endothermic reactions, acids and basics, and carbon dioxide.
Technology: What is an Alka-Seltzer tablet made of?
Engineering: Does changing the size of the container or amount of water or oil change the reaction?
Art: Lay a piece of paper across teh top of the jar and see if you can capture the colored bubbles as they rise to the surface.
Math: How long does the reaction take from start to finish? How many bubbles does each tablet make?

DOING THE EASTER LAVA LAMP SCIENCE EXPERIMENT
Decide how many colors you want to make. We did a green, a pink, and a purple, but Easter colors also include light orange and light blue, and yellow. You could divide your class up into groups of 3-4 and give each one a jar to experiment with.
Fill the jar 1/4 of the way with water. Add a few drops of food coloring.
Fill the jars 2/4 of the way full of oil. Don’t fill it all the way up with oil or when you add the tablets, the jars will overflow.
Break the Alka-Seltzer tablets into 4-6 pieces.
Drop one piece into the jar and watch the carbon dioxide gas carry the colored water to the top of the jar.
The more tablets you add, the stronger the bubbling reaction is. If you add too many tablet pieces, the jar can bubble up and overflow, and the lava lamp bubbles will break apart. Adding less Alka-Seltzer tablet pieces will produce a truer “lava lamp” experience.
