Physical Properties of Materials

5th Grade Science

When you mix materials, you add their masses together.

In the picture, the baker is mixing 15 grams of milk with 30 grams of flour. ​

The mixture makes 45 grams of dough.

(30 + 15 = 45)​

Mass is measured in grams.

Multiple Choice

Cady is completing an experiment in science. She mixes 1 cup of hot milk with 2 cups of cocoa. What will most likely happen to the substances?

• The substances will blend and their properties will be changed.

• The substances will not blend and their properties will be changed.

• The substances blend and form another liquid that appears as a solid.

• The substances will not blend and their properties will be the same as the individual substances.

For example, the mass of the trail mix is equal to 25 grams.

​

The nuts are 10 grams, the raisins are 5 grams, the chocolate ​is 10 grams. When you add them all together, you get the same total of the mixture - 25 grams.

If you measure the mass of individual materials and add them together it will be equal to the mass of the mixture. ​

Multiple Choice

Ms. Shivers wanted to make a salad for lunch. She weighed each individual ingredient before placing it in the salad. Which best describes the weight of the salad compared to the total weight of the vegetables?

• The total weight of the vegetables will be the same as the weight of the salad because the vegetables did not lose or gain weight.

• The total weight of the vegetables will be more than the weight of the salad, because cutting the vegetables increased their weight.

• The total weight of the vegetables will be less than the weight of the salad, because the vegetables weigh less when they are cut

• The weight of the salad will be more than the total weight of the vegetables, because the vegetables were chemically changed.
