Unit 4: Physical Properties of Matter

Juan has three different sized blocks of copper. She made observations and measurements of each block. Which of her measurements would be different? (SC.8. P.8.4)

• The density of each block.

• The electrical conductivity of each block.

• The melting point of each block.

• The volume of each block.

You have a toy that is green, made of iron (metal) and weighs 52 grams. If you drop the toy in a grassy field, how could you find the toy? (SC.8. P.8.4)

• Use a magnifier lens to find the car by its color.

• Place a sample of the field in water to find out its density.

• Weight samples of the area to find a sample that is 52g

• Place a magnet over the area to attract the car.
