Squirrel and I have been talking about matter and classification in science. Here is an easy recipe for a "mystery substance" you can make and then experiment with.
2 cups (or four bottles) white school glue
1 1/2 cups room temperature water
1 cup warm water
3 teaspoons borax powder
Add the room temperature water to the glue in a large mixing bowl. Dissolve the borax powder in the warm water and slowly pour it into the glue and water mixture, stirring constantly. Knead the material until it is smooth and has lost its stickiness. Store the mystery substance in a plastic bag with a zipper for preservation. This is not edible.
Using the mystery substance we talked about properties and classified the properties. We used simple objects, like a wooden spoon, a metal spoon, a glass and a plastic cup, to increase our understanding of this substance.
