Science day in Year 5
Making lava lamps and slime
On science day, we learned how to make lava lamps and slime. We learned that cornflour, food colouring and water makes a non-newtonian fluid which is neither a solid or a liquid. It was both runny and solid when we were playing with it! We explored solids and liquids by studying the oil and salt in the lava lamps. The oil was less dense that the water so it stayed on top whereas the salt was denser and dragged droplets of oil down with it! When the oil reached the bottom, it then floated back up to the top. These activities helped us understand more about the properties and changes of materials which is our science topic for this half term..
