Physical Properties Activity
Children should be able to recognize different sizes, textures, colors, and consistencies of all objects. Explain that combining some substances together makes each substance change its physical properties.
You can give the example of salt dissolving in water. Let the children taste the water to prove that salt still exists in the water, but it just appears different.
Then, create cotton clay. This physical properties activity is perfect because it shows how something as light and fluffy as cotton can turn into something squishy and moldable. Molding the cotton clay also improves fine motor skills and finger dexterity.
- 1 1/2 cups of cotton balls
- 1 cup of water
- 1/3 cup flour
Tear the cotton balls up into pieces. Then, dump the cotton balls, water, and flour together into a pot. Cook over a stove on medium heat, stirring constantly. Once all the ingredients combine, the mixture will become thicker, like clay. Remove from the heat and let cool for about 15 minutes. Let the children touch, play, and mold the clay. Of course, adjust the ingredients depending on your class size. The provided recipe is for two children.
