This week, we have learnt two new words: absorbent and waterproof. If something is absorbent, it will soak up water and if something is waterproof, water will not go inside the object and will drip off. In groups, we tested different objects made from a variety of materials to see if they are absorbent or waterproof. After that, we did a rainbow water test. We made 3 colours of water and used an absorbent tissue to dip into each cup. The tissue soaked up the water and changed colours, which was very exciting.
