Summary Blow paint-coloured bubbles in a tray and make a print on paper. Science content Chemistry: States of Matter, Properties of Materials (K-7) Lessons activity is in Bubbles Materials Bubble solution (1/2 cup) with tempura paint mixed in (2-5 Tbspns). Test and increase tempura if bubble prints are not coloured enough Tray or stable cup for each student Straw for each student Paper Procedure Pour some coloured bubble mix in a tray/cup. A cup will need less mix, but a tray is more stable. Blow bubbles in the paint/bubble mix with the straw. Lay the paper over to make a bubble print. Repeat in another colour paint/bubble mix. Prompt students with questions to help them observe the bubbles closely if necessary: What shapes are the bubbles on their own and when next to each other? What happens to the shapes if a bubble is popped? Science of bubbles can include: the shapes of the bubbles (separated and attached) and how they fall into the most stable configuration; the structure of bubbles - the skin is a layer of water molecules between two layers of detergent molecules, which encloses a pocket of air molecules.
