100

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

100

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

100

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

100

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

100

What is evaporation?
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?

200

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

200

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

200

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

200

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

200

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

300

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

300

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

300

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

300

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

300

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

400

What is a polar molecule?
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?

400

What is diffusion?
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.

400

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

400

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

400

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

500

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

500

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

500

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

500

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

500

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