Question

The pictures to the right show some common baking ingredients: butter, flour, oil, egg, sugar, and milk. Suppose someone wanted to sort these ingredients into two groups, with at least two items in each group. Which of the properties below could be used to sort the ingredients?

Check all of the boxes that apply.

edible or inedible

solid or liquid

white or not white

dissolves in water or does not dissolve in water

Answer 1

Check:
- edible or inedible — no. All six items are edible, so you cannot make two groups with at least two items each.
- solid or liquid — yes. (Solids: butter, flour, sugar; Liquids: oil, milk, egg (raw egg contents).)
- white or not white — yes. (White: flour, sugar, milk; Not white: butter, oil, egg.)
- dissolves in water or does not dissolve in water — no. Only sugar clearly dissolves; the others (butter, flour, oil, egg, and milk as an emulsion/colloid) do not truly dissolve, so you would not get two groups with at least two items each.
