This science tool is used to measure mass. 

What is triple-beam balance or two-pan balance?

100

This is a push or pull that causes an object to move, stop, or change direction.

What is force?

100

This is the amount of time it takes Earth to make one full rotation.

What is 24 hours or 1 day?

100

What powers the water cycle?

What is the sun?

100

This is the term for organisms that create their own food, typically through photosynthesis.

What are producers?

200

This is the amount of three-dimensional (3D) space an object takes up.

What is volume?

200

This is a type of non-contact force of attraction, most notably between objects with larger masses.

What is gravity?

200

This is what causes the day/night cycle and the apparent movement of the sun across the sky.

What is Earth's rotation?

200

This is the term for a liquid turning into a gas.

What is evaporation?

200

This is the term used for living components in an ecosystem. Some examples are leopards, orchids, mushrooms, and toucans.

What are biotic factors?

300

These are the three physical states of matter.

What is solid, liquid, and gas?

300

This is a contact force of resistance between objects that touch. This slows down or stops motion.

What is friction?

300

This is the cardinal direction that the sun sets.

What is west?
300

This is the term for when vapor turns into a liquid. In the water cycle, it's the part that is responsible for clouds in our atmosphere.

What is condensation?

300

This is the term used for organisms in a food web that break down dead matter and help cycle matter back into Earth.

What are decomposers?

400

This is the acronym you can use to remember magnetic metals. Bonus points if you can name each metal in addition to the acronym.

What is SINC? 

(Steel, Iron, Nickel, Cobalt)

400

This type of force is equal in magnitude and opposite in direction. The net force (total sum of forces) is equal to zero.

What is balanced forces?

400

This is the time of day that shadows are typically the shortest.

What is noon or midday?

400
This is the largest source of surface salt water on Earth.

What is the ocean?

400

Beneficial or Harmful: releasing an invasive species, like Burmese pythons into the Everglades

What is harmful?

500

This explains whether an object sinks or floats compared to water or another substance.

What is relative density?

500

This is the type of variable that the scientist purposefully manipulates or changes in an experiment.

What is an independent variable?

500

This is the imaginary line on which Earth tilts that runs through Earth from the north to south pole. Bonus points if you can remember the angle (in degrees) of the tilt.

What is Earth's axis? (23.5 degrees)

500

List the steps of the water cycle, starting with evaporation.

What is evaporation/transpiration, condensation, precipitation, (runoff) accumulation and it starts over?

500

This is the term for the type of consumer who eats both plants and animals.

What is an omnivore?
