10 of the best colorful science experiments

Colorful science experiments They are often much more appealing to younger children than less colorful activities. Adding color to a lava lamp, volcano, or density demonstration makes the activity seem even more special.

I have made a list of my 10 Favorite Colorful Science Experiments for Kids Of all ages.

10 colorful science experiments for kids

Create a rainbow of Skittles

The infamous Experiment with Skittles It will never let you down. It's affordable, simple and looks fantastic.

Kids can turn it into an investigation by using water at different temperatures and arranging the Skittles in different ways.

Colorful potions

Baking soda and vinegar potions can be made colorful by adding food coloring or using Red cabbage indicatorThe purple cabbage indicator is especially fun to use as it changes color depending on whether an acid (vinegar) or alkali (baking soda) is added.

Adding a little dish soap creates an extra foamy potion.

Color density jar

TO multicolour density jar It can be made with water, salt and food coloring!

Blue water contains salt, which makes it denser than orange water, which contains no salt. The denser liquid stays at the bottom and does not mix with the less dense liquid on top. If the glasses were placed with the salt water on top, it would sink to the bottom and the colors would mix.

Two glasses, one on top of the other, filled with water, food colouring and different amounts of salt. One colour floats on top of the other.

Colorful flowers

White flowers can be colored by placing them in a vase with colored water. The colored water runs up the stem to the white petals, filling them with color.

This is a great science activity for demonstrating perspiration.

If you have snow this winter, snow volcanoes are easy to make and leave virtually no residue. A couple of years ago we made four volcanoes in different colors.

Paper chromatography with markers

Colorful paper chromatography This is a simple science activity that can be done using paper towels if you don't have filter paper.

The different inks in the markers move across the tea towel at different speeds, separating the colors.

Black pens often contain more different colored inks and are a great example of how this technique can be used as a separation method.
