Shredding paper changes its size and shape but not this property.
What is weight (or mass)?
When air cools, it takes up less space because the particles move closer together.
What is contraction?
This formula is used to calculate speed.
What is distance ÷ time?
In a race, the object or person with the ____________ is the winner.
What is the least amount of time.
Breaking an object into smaller pieces does not change its total weight.
What is true?
When a sheet of paper is shredded, the total weight of all the pieces does this.
What is stays the same?
A balloon looks deflated in cold weather because the air inside does this.
What is contracts?
If an object travels the same distance in less time, it has this.
What is a greater speed?
A material that experiences a smaller temperature change is better at doing this.
What is blocking heat or being an insulator.
Melting ice changes the state of matter but not the substance.
What is true?
Ice and liquid water are the same substance because they are both made of this.
What is water (H₂O)?
A material that heats up the least would be best for making this item.
What is a glove or oven mitt?
An object that moves 40 centimeters in 10 seconds has this speed.
What is 4 centimeters per second?
If two materials start at the same temperature, the better insulator is the one with this.
What is the smaller temperature change?
A ball left in the cold looks deflated because it lost heat, not because this happened.
What is air escaping?
This action would best show that ice and liquid water are the same substance.
What is weighing them?
What does metal do when it heats up?
What is it expands (gets longer)?
On a motion graph, a steeper line represents this.
What is a faster speed?
A cyclist who travels the same distance every 10 minutes has this type of speed.
What is constant speed?
To find speed from a graph, you must calculate change in distance divided by this.
What is change in time?
Shredding paper is an example of this type of change.
What is a physical change?
To choose the best material for a project, the most important value to compare is this.
What is temperature change?
When a graph line is flat, the object has this speed.
What is 0 centimeters per second or the object is stationary.
To compare how fast something moves (its speed) using a table, you must compare distance and this.
What is time?
When choosing a material that stays cool, the best data to use comes from this.
What is temperature over time?
