When water is spilled at the top of a slide, what does it do?
flow down the slide.
100
How do you change a liquid to a gas?
add heat
100
Give three examples of precipitation
Snow, sleet, hail, rain
100
When water gets hotter, it ________________.
Expands

Define solid and give three examples of it.
A solid is something that keeps its shape.
200
What is the difference between absorbing and beading?
Absorbing means that it is sucked up (or some equivalent answer). Beading means it stays on the surface.
200
How do you change a gas to a liquid.
take heat away.
200
What does it mean to evaporate, and give the number of where it is on the diagram of the water cycle.
Evaporation is when water turns to water vapor.
200
When water gets colder, it ______________
contracts
200
Define liquid and give 3 examples of a liquid.
Something that takes the shape of the container. water, milk, lemonade, honey, oil, etc.
300
What is surface tension.
It is the skin-like surface of water that helps it stay together.
300
What is the freezing point of water in celsius and fahrenheit?
32 degrees Fahrenheit 0 degrees celsius
300
What does condensation mean, and tell the number of where it takes place on the diagram of the water cycle.
Condensation is when water vapor turns into a liquid.
300
Which is denser (heavier), hot or cold water?
Cold water is heavier.
300
Give a simple definition of a gas and two examples of it.
A gas expands to fill the entire space it's in. Air, Helium.

Mikki spilt her coffee all over her desk. What material would she want to use to clean it up: aluminum foil, paper towel, white paper or wax paper? Why?
Paper towel, because it is the most absorbent.

In the morning there is a puddle is on the sidewalk in front of the school. When you go out for recess, it's gone. What happened to it?
It evaporated
400
Give the numbers of run off and accumulation on the diagram?
teacher discretion

Look at the chart your teacher has. What type of precipitation would you expect in Saskatoon, Canada?
snow

Tammy had the same amount of water in a bowl and in a flower vase (see picture your teacher has). She left for the weekend and when she came back to school on Monday, she noticed that the water in the bowl was gone, but that there was still water in the vase. She thought Noah must have come in and drank the water in the bowl while she was gone. Do you think she was right? Why or why not?
No, the water in the bowl would have evaporated faster because it had more area exposed to the air.

What happens when water turns from a liquid to a solid? Use the vocabulary contract and expand.
Water contracts as it cools, until it gets to 4 degrees celsius or 35 degrees fahrenheit. At that point it begins to expand.
500
It's a hot summer day. Your glass of lemonade has water droplets on the outside. Explain why.
The cold glass comes in contact with the water vapor in the air. The coldness changes the vapor back into water.
500
Draw a picture of the water cycle. Include accumulation, evaporation, condensation, precipitation and run off.
teacher discretion

How does a thermometer work?
When liquids get warmer they expand and take up more space. Because of this the liquid goes higher in the tube. When the liquids get colder they contract and take up less space so the water gets lower in the tube.
500
Does all matter have the same boiling and freezing points? Why is this important?
No they don't. If they did every thing would be a liquid, solid or gas at the same time. Life on Earth wouldn't work that way.
