Edible sedimentary layers activity instructions:

You will need: a bowl, a few spoons, a glass or tumbler, 2 or 3 biscuits or cookies of your choice, custard or chocolate pudding, chopped fruit and sprinkles.

Note: You don’t have to use all of these ingredients to make the sedimentary layers. You might have some tastier ideas you’d like to try.

  1. Place the biscuits or cookies on a chopping board or in a bowl and make biscuit crumbs by crushing the biscuits with the back of a large spoon.
  2. Make layers of the ingredients in the glass or tumbler, by adding the ingredients one layer at a time. Start by covering the bottom of the glass with biscuit crumbs. Add a layer of custard or pudding, a layer of chopped fruit and a few sprinkles.
  3. Repeat the layers, starting again with biscuit crumbs, and keep adding layers until you are happy with your sedimentary layer dessert.
  4. Use a small spoon to dig into the layers and eat your dessert. You can travel back in time to a few minutes ago when you added the first layer of biscuit crumbs!

    5. Sedimentary layers form when small pieces of rock, sand, and soil settle on top of each other. The layers can also include left over material from plants and animals. As more and more layers are buried, pressure and time causes solid rock to form, and this type of rock is called ‘sedimentary rock’.
