What is used to show movement in scientific models
?
(What is) Arrows
100
The definition of matter is:
1. Takes up space (has volume)
2. Has mass (weight)
3. Made of tiny particles we can't see
100
What did we see happen when we mixed together baking soda and vinegar on an aluminum plate?
Bubbles (gas)
100
True/False
We can "see" the evidence of air when we see the fan move papers on a table.
TRUE
200
What is missing from the model of the windmill?
Arrows
200
An object that measures weight (mass) by comparing objects
Double pan balance
200
How did we investigate that air has weight? (Must be a specific investigation)
200
True/False
Air only takes up space when we mix together baking soda and vinegar to make bubbles.
FALSE.
Air is a mixture of gasses so it can take up space even if we aren't creating bubbles.
300
What do the arrows and dots show in the inflated balloon?
Answer must include:
1. small particles, air (gas) particles and
2. movement
300
A tool to measure weight (mass) of an object with a number display
A digital scale
300
In science class, we observed that the air cannon knocked over cups.
What did this teach us about air, a gas, and matter?
Gas is matter because it can knock over solid objects. Air takes up space and has weight.
300
True/False
Tiny particles make up all types of matter.
TRUE
400
What should be added to the investigation step by step model to show how we know air, a gas, is matter?
1. Tiny particles that we can't see
2. Arrows to show movement
400
A quantity that expresses a type of measurement that is used in science
A metric unit
400
How can we connect solid objects knocking over cups to our air cannon investigation? 
Air is made of tiny particles we can't see, just like solid objects are made of tiny particles we can't see.
400
True/False
Gas is not a type of matter because it does not have weight (mass).
False.
Gas is a type of matter because the tiny particles that we can't see take up space and have mass
500
How could you enhance the model for someone blowing bubbles?
Response should include:
1. Air (gas) particles
2. Arrows to show movement
500
What are the metric units we use in science class?
Meter, for length
Gram, for weight (mass)
Liter, for liquids

1. Max stated that the deflated basketball weighs less than the inflated basketball.
2. Mylie stated that the players who hit the ball can change the weight of either basketball.
3. Ishaan stated that because air is weight, the deflated basketball weighs more than the inflated basketball.
Who do you agree with?
1. Max is correct because air, a gas, has weight because it takes up space, has mass, and is made of tiny particles we can't see. Because the inflated volleyball has more air inside than the deflated volleyball, that must mean it has more weight.
500
True/False
We can smell onions because tiny particles we can't see move through the air, which is a gas.
True
