What is a slanted surface that we created with wax paper and trays.
What is a slope.
100
In this experiment we learned that water can be absorbed or beads with different materials.
What is dropping water on aluminum foil, paper towel, wax paper and plain paper.
100
When doing the penny and salt/soapy water experiment, we found out that salt/soapy water does what to the surface tension?
What is it lessons the surface tension.
100
In our reading about surface tension, what examples did give?
What is water striders, "overflowing" glass of water, water from a faucet, water on a penny.
100
What are the titles of the other three stories we have read about water?
What is Heat Wave, Trapped by the Ice, The Island below the Star.
200
This is a substance that makes up or comes from the earth.
What is earth materials.
200
In this experiment, we learned about density and how hot and cold water do different things when put into room temperature.
What is putting hot (red water) and cold (blue water) into room temperature water.
200
When water is falling down a slope (slanted surface), which water molecules go faster?
What is the bigger drops of water move faster.
200
When does water move faster, going down a waterfall or out in open water? Why?
What is water moves faster down a waterfall because it is moving downhill.
200
In Trapped by the Ice, what is the large crack in the ground that Ernie Holness almost fell into called?
What is a crevasse.
300
This happens with hot water. It takes up more space or.... This happens with cold water. It takes up less space or....
What is expands and contracts
300
In this experiment, we learned about surface tension and how soapy and salty water have different effects on surface tension.
What is dropping water on a penny.
300
Is cold water more dense or less dense than hot water?
What is cold water is more dense because it sinks.
300
How can you get an egg to float in the middle of a glass? Hint: has to do with salt water.
What is you mix salt with fresh water and then take some of it out. Then you put the egg in and then add more fresh water.
300
In Trapped by the Ice, what is the large monstrous wave called?
What is a Graybeard.
400
This causes the water to stick together and forms a dome over a glass of water. This causes the water not to over-spill.
What is surface tension.
400
In this experiment, we learned that water contracts when cooled and expands when heated.
What is building our own thermometer.
400
Back in the day people used this to move rocks in order to turn grain into flour. Now we use them to create electricity.
What is a waterwheel.
400
When camping on a hill, is it better to put the tent down toward the river or up by the trees?
What is up by the trees because if it rains water flows downhill and could flood the tent.
400
If I said my boat is not seaworthy what would I mean?
What is the boat is not safe for sailing in
500
This is the ability for an object to float.
What is density
500
In this experiment, we learned that when water is poured through two different earth materials it does different things. One absorbs more water than the other. What were these two earth materials?
What is soil and gravel
500
When using the earth materials, soil and gravel, which one absorbed more water?
What is soil because it had less water at the bottom of the cup.
500
During the video we watched about a scientist doing an experiment, he told us he was going to fill the jar with water and then put a screen lid on it. What will happen when the scientist turns the jar over?
What is the water will stay in because all the little holes form surface tension. Once the jar is tilted then the water will come out.
500
What is it called when the weather is unusually hot and sticky for a long period of time?
What is a heat wave?
