Properties and Changes of Matter (Utah SEEd Science, 5th)

(Fill in the blank. Both blanks are the same word, you only need to type it once.)

________ is anything that takes up space. Everything you can see and touch is made of _______. It is the "stuff" in the universe. It is NOT like the following: love, peace, ideas.

There are three states of matter. They are _____, _______, ______. (Type each one separated by a comma but no other punctuation.)

You have learned that matter is made of particles too small to be seen. Would you be able to draw models to demonstrate the particle nature of 1) solids, 2) liquids, and 3) gases on your own?

• Yes, definitely

• One or two, but not all three

• Probably not. I need more help or practice.

You have learned that all matter is made up of tiny particles too small to be seen. If you could zoom in 10,000,000+ times to actually see the particles, what would the particles in the penny most likely look like?

• 
• 
• 
• None of these

These diagrams best represent:

(Select ALL that apply)

• marbles in different containers

• the concept that all matter is made of tiny particles too small to be seen

• a gas, a liquid, and a solid

Which statements explain why the balloon increased in size? (Select ALL that apply.)

• The balloon was being inflated with more air

• Balloons are solid and fill the shape of their container

• Gases will always fill the shape of their container

• When air (gas) was removed from the clear vacuum chamber, the gases (air) in the balloon expanded to fill the container.

What about the particle nature of matter explains why food coloring dropped in water will change the color of the water, EVEN WITHOUT being stirred?

• Food coloring and water are liquids and particles of liquids always spread to take the space of their container.

• Food coloring is permanent.

• Liquid particles do not move or change shape.

• Water is a liquid. It is always evaporating on a scale that can be observed over several days.

Use your understanding of the particle nature of matter. What is likely causing this balloon to inflate when baking soda is mixed with vinegar to produce a bubbly, foaming new substance?

• The balloon has properties like malleability, pink, non-magnetic, a little reflective, and smooth.

• The air in the bottle fills the balloon too.

• A gas was produced when the substances were mixed. Gases spread to fill the space of their containers causing the balloon to fill with gas and inflate.

• Solids and liquids mixed together do not produce new substances and therefore the inflating balloon cannot be explained.

Energy (heat) is added to an ice cube (a solid). What happens to the particles in the ice cube?

• The particles do not change.

• The particles form a tightly compacted solid.

• The particles begin to move more freely and change into a gas.

• The particles begin to move more freely and change into a liquid.
