For our science project this week, we made colors using water and food coloring. My son loves making colors and he especially loves rainbows so he was excited when I told him we were going to make the colors of the rainbow.
The are very few materials for this project. Here’s the list:
- red, yellow and blue food coloring
- several clear jars or clear plastic cups
- pitcher of water (you may need to fill this up several times while experimenting)
- towels (for clean up!)
- bucket (to dispose of the liquid)
- Formula sheet with 3 equations (we used the printable I created for our Los Colores lesson; you can find it here Los Colores)
Before we started mixing colors, we reviewed the formula sheet and made predictions about the colors that would be created when we mixed red and yellow, red and blue and blue and yellow.
The next step was pouring the water. I let my son pour the water himself. He did a great job pouring!
Once the water was poured, the real fun began. We started making colors. First, we made the three primary colors. I explained to him that red, yellow and blue are primary colors and that next we would make secondary colors.
To make the secondary colors, we used the liquid from the primary color jars and poured a little red and then a little yellow into a new jar to make orange, and we did the same to make green and purple. We had to throw out a few batches since the proportions didn’t create the right colors. We had orange that looked too red and green that looked too blue. But after a little experimenting , we were happy with our secondary colors.
When we were all done creating our colors, we put them together to make a rainbow of colors.
Then we mixed them all together to see what happens and my son excitedly said “look, we made black!”
This experiment was fun and easy and teaches the following:
- primary colors
- secondary colors
- pouring (an important preschool skill!)
- making a prediction
Have fun color experimenting!
