Grade 5 Unit 3 Lesson 3

3 properties that you can see are:

• color, magnetism, conductivity

• reflectivity, hardness, brittleness

• brittleness, texture, smell

How much light bounces off a material describes:

• magnetism

• color

• reflectivity

Copper has higher ......... than plastic.

• shininess

• brittleness

• electrical conductivity

The point at which no more solute can dissolve into a solution is called.....

• disappearing

• saturation

• solvent

When wood burns,

• no new substances are created.

• nothing happens.

• ash, water vapor, and carbon dioxide result.

Plastic usually covers power cords because

• it has low electrical conductivity

• it's inexpensive

• it's brittle

If material rusts, it must contain

• wood

• plastic

• metal

Whether a substance can be shaped or not, is a substance's

• brittleness

• hardness

• ability to change

You know that a substance is changing into a new substance if it

• bubbles, smells, tastes sour

• rusts, burns, dissolves

• burns, bubbles, rusts

Light and metal materials are more

• soluble than others

• brittle than others

• reflective than others
