This science activity came about during lunch with my curious kiddo. While eating, Isaac had his head resting on the table and began looking at everything through my empty glass, making comments like: "It looks like an oval," "It looks bigger," and "It looks taller."
We then filled the glass with water and looked again. Things seemed to change! Isaac was fascinated at seeing for the glass and the water made objects look different. We experimented with different objects and glasses. We'll call it a learning lunch hour! It's all about refraction my dear little one!
