G5 UNIT 1 SCIENCE COLD TASK MATTER

How are you able to determine the physical properties of a substance?

• By using the senses to smell, taste, hear, feel, or see it

• By comparing it to the substances that surround it

• By determining its placement on the periodic table of elements

• By observing how it reacts with other substances

Compare the following containers:

Container 1 is clear, bends easily, and quickly melts when near a flame.

Container 2 is not clear, difficult to dent, and does not melt near a flame.

Which container is most likely metal? Support your answer with evidence based on the

given properties.

• Container 1

• Container 2

What is a colloid?

• A colloid is a type of solid that dissolves in water.
• A colloid is a gas that can be compressed easily.
• A colloid is a pure substance with uniform composition.
• A colloid is a mixture with small particles that do not settle out.

Define a heterogenous mixture?
