Slime Time Halloween STEAM Play
Slime is an amazing exploration of solid to liquid and a sensory feast, but introducing different colours can stimulate even more STEAM elements, with prediction, cause and effect and change added to the mix.
The sensory experience also supports fine motor development, strengthens hand muscles, and helps build focus and concentration.
What you need:
Large mixing bowl
Measuring jugs and spoon
500g cornflour
1 1.2 cups water
food colouring (or natural alternative)
What to do:
Add colour to the water, allow children if they like to practice their numbers to count the number of drops as they colour the water.
Pop the water into the bowl and then add the cornflour.
If the mix is too liquid, add more cornflour, if too stiff more water.
Stick your hands in the slime and experience how it feels and how it changes consistency.
You can cover this mix and refrigerate for use again, don't dispose down the drain, find a patch in the yard!
Messy play like this encourages curiosity, creativity and confidence.
