Unit 1 Review

A student examined a patch of mud and recorded

several statements about footprints in the mud.

Which statement is most likely an inference?

• The footprints were pointing North and South

• The depth of the footprint is 2cm deep

• The footprints were made by a cat

• There are 12 footprints in the mud

Which event is most predictable?

• How the Adirondack Mountains were formed

• When a volcano will erupt

• When a seagull will poop on your head

• The moon phases

A student is asked to classify several minerals. For

best results, the classification should be based on

• inferences

• observations

• guessing

• interpretations

Science investigators initially use classification

systems to...

• organize information in a meaningful way

• tell one inference from the next

• clarify observations

• make comparisons

How do you measure the volume of an irregularly shaped object?

• Measure with a ruler

• Measure with a measuring tape

• Measure with water displacement

• Measure with a meter stick

What is the density of an object with a mass of 20g and volume of 4mL

• 80 g/mL

• 5 g/mL

• 4 g/mL

• 16 g/mL

A direct relationship the variables would be

• one decreasing and the other increasing

• both increasing

• one staying the same as the other increases

• both staying the same

What transfers energy through differences in density?

• conduction

• convection

• radiation

• sublimation

What transfer of energy comes from molecules touching molecules?

• convection

• conduction

• radiation

• seagulls pooping on your head

Does density change if an object is broken in half?

• It gets cut in half

• It doubles

• It stays the same

• WHY ARE WE BREAKING THINGS??
