As we are learning all about volcanoes during our Natural Disasters topic, we thought we would create our very own lava lamps to mimic how lava bubbles before it erupts.
Making our lamps used our maths skills as we had to measure out the correct quantities, and we looked at the separation between the water and the oil during the experiment. When we added the effervescent tablet, it was amazing watching the bubbles create and then slowly move up and down. We worked out that the more of the table you added, the bigger and faster the bubbles became!
