c) plasma
d) liquid

When baking soda and vinegar mix, what is released?
a) oxygen
b) water
c) carbon dioxide
d) grease

When baking soda and vinegar were mixed in a closed system, the balloon inflated. Why?
a) Because air has no mass.
b) Because air is partly made of carbon dioxide.
c) Because air is invisible.
d) Because air takes up space.

When a full balloon (closed system) and an empty balloon (open system) were placed on a balance, the full balloon sank and the empty balloon rose. Why?
a) Air has mass.
b) Air is invisible.
c) The empty balloon was heavier.
d) The full balloon had the same mass as the empty balloon.

When we let air out of the balloon and put it on the scale, the amount of weight went down. Why?
a) Less air in the balloon means more mass.
b) Less air is the balloon means less mass.
c) Less air in the balloon makes the particles bigger.
d) Less air in the balloon takes up more space.

You compare the mass of a full balloon and an empty balloon. Which statement is true?
a) The empty balloon will weigh more than the full balloon because of the mass of the air.
b) The 2 balloon will weigh the same because they are both balloons.
c) The full balloon will weigh more than the empty balloon because of the mass of the air.
d) The full balloon will weigh less because of the tiny particles inside it.

When baking soda and vinegar were combined, the gas of carbon dioxide was released because...
a) there was magic taking place.
b) there was an explosion taking place.
c) there was a physical reaction taking place.
d) there was a chemical reaction taking place.

Some matter does not take up space.
a) TRUE. If you can't see it, it can't take up space.
b) FALSE. All matter takes up space, even if we can't see it.
c)
d)

Some matter is made up of large particles.
a) TRUE. The bigger the object, the bigger the particles.
b) FALSE. All matter is made of tiny particles no matter how big the object is.
c)
d)

An example of where we can see the movement of air particles is...
a) water condensation on the side of a glass.
b) the sky during dark at night.
c) when plants photosynthesize.
d) a fan blowing a paper off the desk.

Which statement is TRUE?
a) If you combined baking soda and vinegar inside any closed container, it would not fill with air because it's not a balloon.
b) If you combined baking soda and vinegar inside any closed container, nothing would happen because it is closed.
c) If you combined baking soda and vinegar inside any closed container, it would fill with air because of the chemical reaction.
d)
