60ml of water
60ml of baking soda
Sheet of white paper
Purple grape juice
1. To make the paint, dissolve the baking soda in the water.
2. Dip the cotton swab in the cup and paint a picture. Hard to see?
3. Simply brush over the picture purple grape juice. The picture mysteriously appears in blue-green colors.
All teachers know how much kids love activities which involve magic and surprise!!! My suggestion is that they paint a picture and hand it to the teacher. After, when all pictures are mixed up, they have the revelation moment altogether. Students then, have to find out who painted and the author has to explain why he chose to paint that. Lots of surprise and interaction in your lesson!!!
