I did this project with PK to teach them how to mix primary colors into secondary colors. Each day they’d make a new color. We started on the carpet and I’d find someone wearing the color of the day (green, orange, purple). Make a big deal abut that color! Today we are painting with green (or orange or purple) but oops! I ran out of green paint! What do I do?! Amazingly some PK students will tell you to mix blue and yellow together, if not show them a magic trick! Put yellow all over the page, making sure to use a lot of paint to keep it nice and juicy. Now I will make magic, adding only a little but of blue and spreading it around. The kids will be very excited to see the magic happen. Talk about all the things that are green (orange, purple) and make a list. You can also add texture to the green paper by using scratch brushes or a pencil point and talk about texture. This will give them something to do when they’re done making the color.
Each child receives a new paper that I previously had written their names on the back and taped to either a covered table or whatever you use to keep the table clean because this will get messy. Taping the paper down really helps because then the kids don’t have to touch the paper.
Give them cups of yellow paint and tell them to cover the whole paper yellow. remind them to keep the paint nice and juicy because if it dries you can’t make magic. Walk around the room and as you see the papers turn yellow hand out the blue cups. Remind them to only dip the tip of the brush into the blue so the magic will work. Blue is a strong color so you only need a little.
As the papers turn you can hand out some tools for scratching and they love to do this. By the third color the kids get the process and do it on their own. I recommend big fat brushes for the kids who don’t have the grip yet.
I keep a table set up with the color of the day crayons and paper so that as they finish and clean their hands they can go there and continue to color in the color of the day. This will give you time to get the paintings on the drying rack.
Before you let them leave show two versions of the color. So if you’re doing green show a green that is more yellow and one that is more blue. Ask what the differences are and let them tell you. Ask why they think they are different. They can see how to achieve a darker blue green by adding more blue, or a lighter yellow green by adding less blue and talk about what you’d use these colors for!
Last day, assembling the sunsets. Purple is for the background, orange for the sun, green for the grass. Show them how it is done on the carpet first. I make a half circle on the back of all the oranges for them to cut and follow the line. The rays can be done 2 different ways. Kids can cut them or rip them, depending on their ability with scissors. Show them to add glue to the back of their pieces first, then glue it down on the purple paper. Show them how to cut the grass, by ripping or cutting a strip and ripping or cutting halfway along the strip. Glue it all together and done!
