Year 4 had a wonderful ‘potions day’ filled with experiments and activities that launched our new science topic ‘states of matter’. We started the day sorting a variety of materials into solids, liquids and gases and learning about their particle arrangement. Next, we answered the investigation question “Is custard a liquid?”. Our class science ambassadors helped lead a series of experiments that led to children questioning the matter classification and properties of custard. We finished the day creating gas reactions within our own potions, and children made their own colourful fizzing lava lamps.
