Multiple Choice

What do you call the amount of space an object takes up? Measured by length, width, and height.

• Mass

• Matter

• Volume

• Density

Volume

The amount of space an object (in this case, the water) takes up

Multiple Choice

This determines an objects ability to sink or float

• density

• mass

• volume

• weight

Density

determines an objects ability to sink or float

Multiple Choice

The Scientific Method

Let's look at the steps...

Scientific Method

• Make observations

• Form hypothesis

• Design an experiment

• Gather data

• Draw conclusions

Multiple Choice

What is a variable in an experiment?

• changes and affects the outcome of the experiment

• a prediction made before the experiment

• a careful watching of something using the 5 senses

Variable

independent vs. dependent

Multiple Choice

What do we call a prediction that we make that can be tested about how an experiment will turn out?

• data

• outcome

• hypothesis

• variable

Multiple Choice

What is data?

• information or facts collected

• the result of something

• a decision or realization
