Cornstarch gloop (6 months and older)

Non-Newtonian fluids 101

Home Learning

You will need

  • 2 cups cornstarch
  • water
  • medium sized container
  • food colouring

What to do

In order to form the ‘gloop’ consistency, add the cornstarch into the container and slowly add in water - mixing it until it reaches a firm but moveable state. Add in a couple drops of food colouring and allow your child to explore the mixture with their hands and spoons. This activity is excellent for little hands as the strange consistency encourages play as it changes from a solid to a liquid, whilst the consistency, being thicker than water, strengthens the muscles they will one day use for tasks such as writing.

Note: To avoid blockages, when you are finished with the gloop, be sure to dilute the gloop with plenty of water before tipping it into the drain.

Learning outcomes

  • Understanding the world: developing their sensory processes
  • Fine motor skills: strengthening their hands and arms
  • Experimentation: observing the mixture change between states as they manipulate it

Ask your child

  • What does it feel like?
  • Can you stir the mixture?
  • What colours can you see?
  • Is the mixture hard or soft?
