Our Science lesson began with a story today. We read "Harry the Dirty Dog" by Gene Zion. In this story, Harry the dog is a white dog with black spots who does NOT like to take baths. In fact, he dislikes them so much he buried his scrub brush and ran away from home. After being gone for awhile and getting really dirty, he returns home only to realize his family does not recognize him! He finally digs up the scrub brush, begs for a bath and is reunited with his family!
So now, it was time to dye our fabric. We have soiled it and washed it. Now we were curious about how to change the color of fabric. First, we prepared the dye. We used 1/3 cup of warm water, two teaspoons of vinegar and 10 drops of food coloring. We used red, blue and yellow.
Next, we had to fold or crumple our piece of fabric. Then we dipped it in the dyes and blotted it on paper towels. Then we got to unfold our fabric samples and guess what we discovered??
When we opened up our fabric, we saw red, yellow and blue. But we also noticed that there were colors that we didn't even use! We saw green, orange and purple too! How did this happen? We discovered that when you mix some colors, you actually get another color. For example, if you mix blue and yellow, it makes green. Red and yellow make orange. Red and blue make purple. We were so surprised to see this and learned something new and cool today.
