In Miss Crawford’s class the experiment was to make a lava lamp using different materials. We looked at the materials and suggested how the lava lamp would work.
The children discussed what they thought would happen when we put the ingredients into the bottle, lots of them quickly realised that the oil was a much denser liquid and therefore wouldn’t mixed with the water. They made suggestions like ‘The oil must be the lava’. We discussed the importance of the Alka Seltzer and children made sensible predictions about what might happen when it was added to the liquid.
The children were fascinated to see the effects when carrying out the experiment and made some super observations. We then discussed what we might do differently next time. The children made suggestions such as; changing the temperature of the water and adding more Alka Seltzer.
