Changes and color mixing

This week we are learning about color mixing in school. We are doing a walking water color experiment and colored ice cubes mix. The children will color on coffee filters with markers and then wet the filters to let the colors bleed together. We are also doing rainbow writing with their names and sorting pom poms by color.

Water walk color experiment: You fill cups with water (I used 9 cups) set the cups in sets of three. Put color into the outside cups and leave the middle cup with just water. Then put paper towel “bridges” between the cups. The water will begin to wick up from the colored water cup into the plain water cup. Then the two colors will mix together. This took a LOT more food coloring than I expected. I ended up having to put food coloring right at the top of the “bridge” to get it to mix. But in the end, it worked and the children got to see yellow and blue make green, red and blue make purple, and red and yellow make orange.

Colored ice melt: Fill and ice cube tray with water. Add a few drops of food coloring to the sections to color the ice red, blue and yellow. Once frozen, you can put the ice into clear cups and then let the ice melt together. As it melts you should see the colors begin to mix. When we do this I will also add a cup that has red, yellow and blue so they can see it mix together into brown.

Coffee filter color mixing. This is a process based art activity. The children draw on coffee filters with markers. Then you have them use pippets to drop water onto the filter a few drops at a time. The marker colors will then begin to bleed and blend. Often times you will also see the colors separate. This is really cool when the black starts to separate into other colors.

Rainbow writing is a great way to help children master writing words. You write a word in one color, pencil or black works best. Then you have the children choose 3 or more crayons. The children have to write on top of the word you wrote with each of the three crayons, layering each on top of the last color. The more you write it the more colorful it becomes, and writing in layers of crayon helps build up the “feel” of the paper. (I often had my first graders use this method to practice spelling words)

Our poem this week is very simple and the children are already mastering it. I wrote it out on chart paper writing each line in the color word at the beginning. I then added quick illustrations to help them remember the last word. The children then had to illustrate their copy of the poem for their poetry journal.

Brown is a bear.

Purple is a plum.

Blue is the sky.

  1. Sounds like a fun week! I’ve seen the colour walking experiment but haven’t done it.
    I do a similar art project to the coffee filters, but use paper towels instead as we don’t have to buy them.
