A Yellow Lunch (Tuesday):
Soft Pretzel with Honey Mustard Dip, Egg Salad, Banana, Lemonade.
A Green Lunch (Wednesday):
Split Pea Soup, Quesadillas on Spinach Tortillas, Green Grapes, and a Key Lime Float. (Limeade mixed with sparkling water, topped with a scoop of vanilla ice cream.)
We're having such fun with our rainbow experiments. First we did an experiment about sunlight, putting a black piece of paper and a white piece in the sun for 20 minutes, and feeling them. The black piece was hot because black absorbs all the light (and therefore heat), rather than reflecting any of the waves back. The white reflects ALL of the waves back (all the colors together make up white light), and because it reflects the light rather than absorbing it, the white paper stayed cool.
This experiment used a few drops of each of the primary colors in milk, a drop of dish soap in the middle. We checked on the bowl every 15 minutes, and the kids made drawings of their observations at each checkpoint.
The kids loved playing with primary colored (transparent) paddles, combining them to see the secondary colors they made. They recorded their observations by drawing overlapping squares.
Squeezing a bit of mathematics into this week, we played with Skittles ("Taste a Rainbow!"). We opened our packs, made predictions about the color ratios, then counted each color and made bar graphs to visualize which had more. We did addition, subtraction, and averaging, to figure out how many we'd have to give or take to make us all have equal amounts of each color.
This has been a great tool for playing with color - the little wooden blocks are magnetic. Great for pictures, patterns, color combinations, etc.
And I'll end today's post with this fun display of sugar and artificial colors... but it was just too fun NOT to make. A Jello Rainbow.
