Homemade Lava Lamp Experiment
Science is so much fun! What’s great about these science experiments is that you can enjoy them in the classroom as well as at home with friends and family. You are able to do these experiments at home by looking around in the cupboard and finding materials that you can use to create a science experiment out of! This blog will be giving you fun and creative ideas to incorporate science activities for the whole family to enjoy!

Indoor Activity: Homemade Lava Lamps
Purpose: This experiment models what’s happening inside an active volcano. Children will use and learn the scientific method. Children will be using their cognitive, physical fine motor, collaborative, and linguistic skills.
For ages: 5-12
Time: 5-10 minutes prep time, 10-15 minutes for experiment, 5-10 minute discussion with observations, 5-10 minute clean up.
-clear container (plastic bottle or jar with lids)
Safety: Make sure that the child does not eat anything from the experiment. Although all of the materials are edible, they may not taste good together. Also make sure the child does not touch their eyes or face after touching the materials, to avoid irritation.
Reasoning/Discussion: When you add water and oil together, we know that they don’t mix. It’s kind of like when you put to magnets together on their opposite sides; they don’t want to cling together. The water and oil doesn’t want to mix, they want to stay separated. The Alka-Seltzer tablet releases a gas into the solution which creates the bubble like motion of the lava, as if you were blowing bubbles underwater with a straw. Just like in a volcano where gases are released inside and liquid gets pushed up and down inside the volcano and bubbles.
