Rainbow in a Jar
Get ready for a WOW spring science experiment for kids of all ages!
ThisRainbow in a jarexperimentis a great way to teach density for kids in a meaningful and memorable way!
Thisdensity rainbowis a funspring science.
Basically density i s how tigh the molecules are in a substance.
The balls are more densly packed than you are.
Stir to make a purple color liquid.
Now carefully pour the most dense liquid into a clear glass or plastic container.
Rainbow in a jar science experiment
In a seperate container mix water and green food coloring.
Carefully add the green liquid to your density jar.
Again, be very careful when pouring in the liquid so the colors dont mix.
Finally mix rubbing alcohol with red food coloring in a small container.
Now carefully pour the red liquid into the density jar.
Again go slowly or the food coloring will mix together and you wont get a pretty rainbow.
The rubbing alcohol is the least dense liquid in your density in a jar experiment.

Isnt this spring science project so fun!
I love seeing the kids faces when they watch it all come together and the concept of density clicks!
