Lava Lamps


Remember the groovy days? ..or maybe you are too young to actually remember them but still appreciate that era in time. Anyway, here is a fantastic and easy science activity to do with preschoolers or even school age kids for that matter!  This project would work well for a class demonstration. I did this with my kids at home and they totally loved this project. I guarantee that kids (and adults too!) will go crazy for this activity! Extra fun tip: Do this activity dressed up in Groovy clothing and end the session with a dance party complete with music from the 60’s and 70’s!

To make a lava lamp all you need is:

Clear container  ( can use glass jars or empty pop bottles)


Food colouring

Cooking Oil

Alka Seltzer tablets

Directions:  Fill the container 3/4 full of cooking oil. Fill the rest of the way with water. Add a few drops of food colouring. Let the children drop in the alka seltzer tablets to watch the lamps sizzle! For added effect turn off the lights and put a flashlight behind the jar!
