KRCS students celebrated International Dot Day.

Pre-K scientists experienced how blacklight (ultraviolet light) can change the way things look. We drew dots with highlighters on one side of yellow paper and wrote our names on the other side, but they were hard to see. Then we took those papers into my walk-in science closet. When I turned on the blacklight bulbs, our dots appeared! We also noticed that other things in the closet seemed to be glowing, like the fluorescent stars on the ceiling. It was a pajama dress down day too.
