We are homeschooling Rosa again this year and also continuing Carlyn's and Enzo's education in a very casual and fun manner. Basically we take normal everyday moments and turn them into teachable moments.
This morning's activities started with Carlyn putting the silverware away (which is a great sorting activity for toddlers). She found a medicine dropper in the drawer and asked what it was....
So the idea hit me, I will show her how the dropper works (fine motor skills) and let her experiment with colored water.
What I used for this experiment: (amazon affiliate links)
5 clear/white containers
Red, Yellow & Blue food coloring
Crayola 24 pack of twistable crayons
Science notebook or paper
For a two to three year old, the activity of figuring out how the dropper works and mixing colors to get a new color is challenging enough. I gave her five containers. Three I filled with about 1/2 cup of water and added two drops of food coloring (blue, yellow and red) to the containers.
The last two containers were used for mixing. I showed her how to use the dropper and pull the water into the tool, then place it into an empty container. She chose the colors and we talked about what was happening as she experimented.
Rosa, at age six cam along and wanted to experiment too. Since she is a bit more advanced I asked her to record her experiments in a journal. We have a great pack of Crayola Twistable Crayons for this activity. The crayons provide a variety of hues for her to match up to colors.
So, I asked her to find the crayons that matched the colors she was adding, then record how many droppers she used in her mixture. Once she was done mixing, she recorded the result on the far right.
Her first experiment was two droppers of blue and four of yellow which resulted in a teal color.
She then mixed red with the teal and got brown in her second experiment.
You can modify this activity several ways.
Older children can write the names of the colors rather than use crayons.
Younger children can record simple color mixtures with their crayons or markers.
Older children can try to figure out which combinations will create a certain hue or color.
More advance students can record the liquid amounts in mL (found on the side of the dropper)
