This material soaked up the most water in our first experiment.
What is a paper towel?
100
Cold water is __________ dense than warm water.
What is more?
100
The process by which liquid water turns into water vapor is called ____________ ?
What is evaporation?
100
This is how you could tell that your water was getting cleaner when we filtered it.
What is the color got clearer, there was less gunk in the cup, or it smelled better?
100
This is the property of water that causes it to collect in drops on a surface.
What is beading or surface tension?
200
This property of water causes it to form a sphere held together with a skin-like surface.
What is surface tension?
200
Ice is _________ dense than both cold and warm water.
What is less? That's why it floats!
200
These two factors will effect how quickly water evaporates.
What are surface area and temperature? The more of these there are, the more evaporation will occur.
200
This material filtered out the big chunks best. Was it the screen, cotton ball, or the sand?
What is the screen?
200
This is the property of a material in water that describes how it stays at the top.
What is floating?
300
Water will always flow in this direction.
What is downhill?
300
When water freezes into ice, it will _____________ .
What is expand? We saw this happen with the syringes and the vials.
300
When water vapor collects on a cool surface and becomes liquid water again, it is called ___________ .
What is condensation?
300
This material soaked up color best. Was it the screen, cotton ball, or sand?
What is the cotton ball?
300
This is what liquid water becomes when heat is added and it is exposed to the air.
What is water vapor?
400
More mass and more slope will make water run ________ .
What is faster? The more water that there is and the steeper the slope that it is on, the faster it will run down.
400
After ice melts, the cold water from it will ________ .
What is sink? This is because the cold water is more dense, but the ice is less dense than the water it is floating in.
400
If you put one cup of water in the refrigerator, and pour one cup of water on the sidewalk in the summer, which will evaporate first?
What is the cup spilled on the sidewalk? More surface area and higher temperature!
400
A terrible smell would tell you this about the water quality.
What is that it is BAD? Don't drink stinky water!
400
This is the property of water that causes it to go from water vapor to liquid water.
What is condensation?
500
This is the chemical formula for water.
What is H2O?
500
This is why do pipes in unheated building have to be emptied before the winter.
What is the water will freeze, expand, and break the pipes?
500
This causes rain to form. (Hint: there are at least two words needed here :)
What is evaporation (up to the sky), and condensation (to form clouds). Next, precipitation happens when the water can not stay up there any longer.
500
This is one reason that we could not get the water clean enough to drink.
Name anything that makes sense. There were many reasons!
500
This is the shape that water will take on a surface because of surface tension and gravity.
What is a dome?
