unflavored gelatin
food coloring

Mix many packets of gelatin with half of gelatin manufacturer recommend amount of water. Cook according to manufacturers directions. Chill in a deep bowl – the more depth and gelatin, the better. After it has set, for at least 12 hours, release from bowl, place upside down on a cookie sheet – it should look like a hill. Fill pipettes with food coloring. Insert pipettes into gelatin mold and squeeze out the coloring. The children love to experiment with this. You might want to use smocks, the food coloring can squirt out of the mold. The gelatin can be reheated and molded again.

To teach my students about mixing colors to create new ones, I paint one of their hands one color and the other hand another color. I then make handprints in the upper left-hand corner and the lower right-hand corner. I then have the children rub their hands together and when the new color is created, they make two handprints in the center of the paper to show what happens when the two original colors are mixed. I then make a book of their colors, laminate it and hang it on the easel so that they can create colors while they are painting, coloring, etc. This is very helpful in teaching children how to create secondary colors. For example: Left hand yellow, right hand red, two hands in the middle make orange.

In our sensory table we place a muffin tin filled with different colors of water( use food coloring to make the colors), a large empty container, a clear plastic cup for each child working in the area, and one medicine dropper for each child working in the area. The children take the water with the medicine dropper and add it to the cup to explore the results of mixing colors. When their cup is full or they want to start over they simply empty it into the large container. This activity is fun and easy to clean up.

This is a fun color mixing experiment that we do at our preschool. We take four clear film containers and four different color water (food coloring) that are also in a clear plastic cup and we give the children eye droppers and have the children mix the colors. The children are amazed at the colors that they make. A good story to read with this experiment is Mouse Paint and Little Blue and Little Yellow. Happy mixing!

For pink week we added red water to white corn starch. (You could use any color) This made pink goop and we talked about mixing red and white to make pink. Then my 3’s really loved playing in the pink goop. We also got to talk about liquids and solids since this stuff looks like a liquid but sort of acts like a solid.

Color Mixing Discovery Bottles-Color water with food coloring (primary color) and pour into clear soda bottle. Color vegetable oil with powdered tempra (2nd primary) and add to bottle. Super glue the top onto bottle to prevent opening. Colors will mix to form secondary color when shaken, then separate again when undisturbed. My kids also enjoy colored water and clear baby oil and colored Karo syrup with colored beads or small trinkets.
