…and the science of FIZZING PANCAKES!

This is a recorded LIVE LABS session from the 16th of February 2021

You will need: A plate, 1 lemon plus some extra lemon juice, baking powder or bicarbonate of soda, food colouring, a teaspoon, and a tray

Erupting Lemons:

  1. Before you cut your lemon gently squeeze and press your lemon to release some juice inside.
  2. Ask an adult to carefully cut your lemon in half.
  3. Place both halves (juice side facing upwards) on the plate so they sit flat.
  4. Add a few drops of food colouring to each lemon half (a different colour for each half if you have it) and mix with a spoon or fork.
  5. Add a teaspoon of baking powder/ bicarb to each half and gently mix it in with the lemon juice and watch the lemon react.

Fizzy Tray:

  1. Evenly cover a tray with Bicarbonate of soda
  2. Pour some lemon juice into 2 pots and use food colouring to make them different colours
  3. Using a Calpol or a similar medicine syringe, draw up some of the lemon juice and drop some over the tray.
  4. Watch the fizzy eruptions and make some fizzy patterns
