100

This property of water allows a pin to float on the surface of water.
What is cohesion at the surface (surface tension)?

100

This is the number of hydrogen atoms in a water molecule..
What is two?

100

How do we calculate the density of an object or substance?
What is divide it mass by its volume?

100

A student is recording the volume of a liquid. What unit of measurement will she use?
What is liters?

100

After swimming, you leave your towel out in the sun. An hour later, the towel is dry. What part of the water cycle best describes this process?
What is evaporation?

200

This property of water demonstrates the attraction of one water molecule to another.
What is cohesion?

200

This is the number of oxygen atoms in a water molecule.
What is 1?

200

In the lab, what tools are commonly used to measure mass?
What is a scale or double beam balance?

200

In the lab, what tools are commonly used to measure volume?
What is a beaker or graduated cylinder?

200

Snow, rain, sleet, hail. These are all examples of what part of the water cycle?
What is precipitation?

300

This property of water allows water to "climb" up substances.
What is capillary action?

300

This is the chemical formula for water.
What is H20?

300

This is the smallest particle of matter.
What is an atom?

300

This unit of measurement is used to label mass.
What is grams?

300

Clouds and fog are examples of what part of the water cycle?
What is condensation?

400

Water molecules tend to "stick" together because of positively and negatively charged "ends" of the molecule. So, we say it is what kind of molecule?
What is a polar molecule?

400

This refers to the movement of molecules from an area of higher concentration to an area of lower concentration. We observed it in the "All Mixed Up" lab.
What is diffusion?

400

This is formed when two or more atoms combine. For example, water is one.
What is a molecule?

400

This is how density is labeled.
What is g/ml or g/cm3?

400

Lakes, rivers, streams and puddles are examples of what part of the water cycle?
What is accumulation?

500

This property describes tightness across the surface of water, caused by the polar molecules pulling on one another.
What is surface tension?

500

In the "All Mixed Up" lab, we found that this variable influences the rate of diffusion.
What is temperature?

500

When two or more atoms bond together, what us made?
What is a molecule?

500

This system of measurement is used in science.
What is the metric or SI system?

500

What part of the water cycle is not visible?
What is water vapor or evaporation?
