Set up Fill the up with 1 cup of water. Add 5 different drops of food coloring. Write down what five color drops you put into the cup.
Discussion Present the cup of colored water to the kiddos, then show them the four colors from the food coloring. Tell them how many drops of coloring you put in and ask them if they think they can figure out the matching combination. Inform then that today they are color detective and their job is to crack the case of mystery color.
How To Fill clear cups with 1 cup of water (The amount of water in the cup may affect the outcome so its better to measure). I asked the kids to write down what combination they thought was in the cup. I had them record it on this printable data tracking sheet. With the older kids I allowed to mix their own combinations, but with the younger ones I had them wait for assistance. After the first try if the kiddos are unsuccessful have them analyze the colors, comparing them to original water color. Is it lighter? Darker? what could be changed?
Dump out the old water, fill the cup once again with 1 cup of water and have them try again. Kids could have done this all day if they were allowed. All the children ages 5-12 enjoyed this. An fun and affordable STEM activity for kids!
