Over the past few weeks Cohort A has been taking an interest in 'designing' activities, such as building roadways for towns, snow sculptures, ice art, etc. For one activity this week our children worked with water, dry erase markers and a glass plate. The idea was to see if the water could get the design they made with the dry erase marker to dance on the plate.
The children were encouraged to draw shapes, stick people, or any idea they had on the glass plate. After they drew the image, I asked them if they thought the picture they drew would dance on the plate. A few of them decided to make predictions and see if they were right.
They all said it wasn’t going to work.
The best part was when they questioned the activity... how did it work? Why did it work?
So, we had a discussion about the different steps they needed to take to see how it worked and how the ink floated in the water. We talked about how the marker was leaving behind a mixture of pigments and a type of alcohol together. After the alcohol dissolve, all that’s left is the pigment of colour as a solid. With the plate being smooth, when you pour the water on the plate the coloured drawing should slide off the plate and float in the water. One of the kids said, “oh that’s how it works?" and another, “that’s so cool”.
Seeing the expression on the children’s faces as they realized that they have done magic was priceless. I say magic because one of the kids said, “I’m doing magic”, as they kept on dumping the water off the plates and drawing different pictures to see if each one would lift off the plate.
Come back to see what we have planned next!
