For Mothers' Day, the Junior Science Club cut out paper flowers and coloured them. Then we folded in their paper petals and floated them in water. After a while, the paper soaked up some of the water and that made the paper swell up and the petals started to open by themselves.
The Senior Science Club diluted different coloured dyes and poured them carefully into test tubes using plastic funnels. Then we placed white flowers in the dye. The flower sucked up. The flower sucked the liquid up the stem, so that after a day of two, the white petals changed colour . . . just in time to present to our Mums for Mothers' Day.
