Today you will be carrying out some investigations into density of liquids. You will need the following for each investigation. If you can only do one, that's fine. If you don't have the ingredients needed, don't worry, they will be shown on the video for you to watch.
Investigation 1: some golden syrup, some vegetable oil, some maple syrup or honey, some food colouring (any colour), a large clear plastic cup or pint glass, a spoon, and some washing up liquid.
Investigation 2: some vegetable oil, an effervescent tablet like a vitamin C fizzy tablet, a torch, some food colouring, a 500ml bottle, a spoon and some water.
