Summary Use the "Bubble Thing" to make giant bubbles. Students make their own large bubbles with a home made bubble frame. Science content Chemistry: States of Matter, Properties of Materials (K-7) Lessons activity is in Bubbles Colours in light Materials Bubble thing/Giant bubble maker (Klutz carries it) Bucket of bubble mix with glycerol in it (1/2 baby shampoo, 1/2 water, a tablespoon or two of glycerol) Loop of string through two straws for home made giant bubble maker Tray to dip home made bubble maker into Procedure Giant bubbles outside as demonstration. Students make frame from a loop of string and two straws. Make own bubbles. Watch the changing shape and colours in the giant bubbles. The colours are due to the structure of the bubble skin - two layers of molecules, which separate white light into its colours. Notes Students did not get to make their own bubble maker - just showed them. DI Science workshop looked at the colours in giant bubbles with a lesson on light.
