Year 4 Lava Lamps!

To celebrate British Science Week, both Birch and Ash took on the task of making their own lava lamps!

With water, oil, food colouring, and an effervescent tablet, year 4 managed to create an amazing display of colourful bubbles due to the sodium bicarbonate reacting with the water.

This experiment demanded reciprocity between pairs which both classes demonstrated superbly.
