Home School Science 101 - Lava Lamps

As a homeschooling photographing mom, we get to do a lot of cool things for science. On this day, we were seeing the weight difference between water and oil, simple right? But we upped the fun with a little food color and Alka Seltzer tablets. So we followed these instructions: http://www.stevespanglerscience.com/experiment/bubbling-lava-lamp

But then we made a few changes which made it easier for us :) after we had finished the first home made lava lamp.

1. Fill the bottle of your choosing about 1/4 full of water.
2. Add food coloring to your liking for color, and yes you can mix colors to create your own personal favorite. Mix thoroughly to infuse the water with color.
3. Fill the bottle the rest of the way with cooking oil. We used Canola and it worked just fine.
4. Split the Alka-Seltzer tablets into fourths.
5. Drop one at a time, let dissolved completely to prevent cloudiness.
6. Have lots of fun and it can be reused a lot!

We did this for a science experiment with our home school group, and the kids loved it!  I hope you get out there and have fun schooling your kids!
