Science Challenge - Make a Jelly Scab
*You will need adult help for this*
Resources:
- Red Jelly
- Crushed Weetabix or other cereal
- Baking paper
- Spoon
Instructions:
- Make the jelly according to the instructions and leave to cool until it is just starting to set (ask an adult to help you with this).
- Lay the baking paper on a flat surface and use the spoon to drop the jelly onto it.

- Once the scab is hard, gently peel it off the baking paper and place it onto your arm/leg.
Please send a photo on Class Dojo to your teacher. All entries will receive a sticker.
The Science
As soon as you cut your skin, platelets jump to the rescue. They stick together around the damaged skin to form a clot. The clot becomes a scab and it stops harmful bacteria from getting into the opening of your skin. It’s important not to pick scabs as new skin cells are being made and damaged vessels repaired.
Science of the Month: Human body
Choose one of the following topics to investigate:
- Can you find out 5 facts about the human body? Here is one to get you started….You lose around 4kg of skin cells every year!
- Using different types of pasta, can you make a human skeleton?
- Record your resting heart rate and then exercise for 2 minutes. Record your heart rate for three minutes after exercising to see how long it takes to return to its normal rate. Can you make a graph to show your results?
