1pktMini Starburst Fruit Chews,or normal sized starbursts
Large white plate
Small microwavable plate
Zip lock bag
Microwave or a hairdryer
For this experiment, we used a packet of mini starburst fruit chews which we purchased from Amazon, though you could use the normal sized starbursts and cut them into four cubes.
Caution - Don't touch hot candy, let it cool first.
Sediment - If you are using normal sized starbursts, carefully cut them in half and then in half again - making four squares roughly the same size. Place the small pieces of candy onto the large white plate - we used 8 pieces. Cut out the label and place it or next to them.
Sedimentary Rock - To do this, we used 8 pieces of starburst and pushed four pieces on top of each other, then repeated this and then squashed them gently together. Cut out the label and place it or next to them.
Metamorphic Rock - When you apply heat and pressure to the sedimentary rock, you get a metamorphic rock. To do this, place 8 pieces of starburst candy into a ziplock bag. Push the candy pieces together to create a ball. This will take some time as it needs the heat of your hands and pressure to create. If you have young children, they may find it easier to stand on them, creating a flatter rock. We did this three times, creating three different metamorphic rocks - two to use later on. Cut out the label and place it or next to them.
Magma - To make the magma, cut a small piece of baking paper and place it on the small plate. Place one of the 2 extra metamorphic rocks on top of the baking paper and place the plate in the microwave for 30-40 seconds. Remove from the microwave. It will be hot, so don't let children touch it. Cut out the label and place it or next to them.
Igneous Rock - When the magma is cooled, it becomes igneous rock. We repeated the instructions for the magma rock and let it cool, so that we could so the different parts of the rock cycle on the plate. Cut out the label and place it or next to them.
When the igneous rock is weathered and erosion happens, it will turn back into sediments and the cycle starts all over again.
If you can't use candy, you could try completing this experiment with clay or playdough. Though, you can't heat these, it will give you an idea of what is happening.
