1.
What are the three forms of water?
2.
What takes up more space, water as a liquid or water as a solid?
Correct Answer
B. Water as a solid
Explanation
Water takes up more space as a solid compared to when it is in a liquid state. This is because when water freezes and turns into ice, its molecules arrange themselves in a more structured and spread-out manner, causing the solid form to occupy a larger volume. In contrast, in its liquid state, the water molecules are more closely packed together, resulting in a smaller volume.
3.
What is not a way to measure tempature?
Correct Answer
B. Richter
Explanation
The Richter scale is not a way to measure temperature. It is actually a scale used to measure the magnitude of earthquakes. Temperature is typically measured using the Fahrenheit or Celsius scales.
4.
At what tempature Celcius does water change from a liquid form to a solid form?
5.
What is the process of a liquid becoming a gas?
Correct Answer
B. Evaporation
Explanation
Evaporation is the process by which a liquid turns into a gas. It occurs when the liquid's molecules gain enough energy to break free from the surface and enter the air as vapor. This process is influenced by factors such as temperature, surface area, and air movement. Evaporation is an important part of the water cycle, as it allows water from oceans, lakes, and rivers to enter the atmosphere and eventually form clouds.
6.
What is the process of water vapor in the air that turns back into a liquid?
Correct Answer
B. Condensation
Explanation
Condensation is the process in which water vapor in the air cools down and turns back into a liquid. This occurs when the air becomes saturated with water vapor and cannot hold any more moisture. As the air cools, the water vapor molecules slow down and come closer together, forming tiny droplets of liquid water. These droplets can then collect on surfaces, such as clouds, or form dew or fog. Condensation is an important part of the water cycle, as it plays a role in the formation of clouds and precipitation.

What will happen to a cup of water outside if the tempature is -10 degrees Celcius? What if the tempature is 10 degrees Celcius? What if the tempature is 100 degrees Celcius?
Correct Answer
C. Freeze, get cold but not freeze, evaporate
8.
What is the tempature in Farenheit if the thermometer shows 0 degrees Celcius?
Correct Answer
C. 32 degrees Farenheit
Explanation
The correct answer is 32 degrees Fahrenheit. This is because 0 degrees Celsius is equal to 32 degrees Fahrenheit. The two temperature scales have different starting points, with 0 degrees Celsius being the freezing point of water and 32 degrees Fahrenheit being the freezing point of a salt and water solution.
9.
A march is a wetland. In the winter the tempature is below 0 degrees Celcius. In the spring the tempature is above 0 degrees Celcius. What do you think will happen to the water in the march in the winter and the spring?
10.
Describe the water cycle? Why is it important?
11.
What causes water to evaporate?
Correct Answer
A. Sun's energy and winds
Explanation
Water evaporates due to the sun's energy and winds. The sun's energy provides the heat necessary to increase the water's temperature, causing it to turn into vapor. Additionally, winds help to speed up the process of evaporation by moving the air around, allowing the water molecules to escape into the atmosphere more quickly.
12.
What causes condensation?
Correct Answer
B. Cold air
Explanation
Condensation is caused by cold air. When warm air comes into contact with a cold surface, it cools down and loses its ability to hold moisture. This leads to the formation of tiny droplets of water vapor, which we observe as condensation. Cold air has a lower capacity to hold moisture compared to warm air, so when the warm air is cooled, the excess moisture is released as condensation.
13.
When does precipitation happen?
14.
What causes some percipitation to be snow instead of rain?
15.
Explain the main steps in the water cycle. You can draw a picture if you want.
16.
Why must the water that people drink and use be cleaned first?
17.
What are ways a water treatment plant cleans water that will be used by people?
18.
How many sides does a snowflake have? What is it's shape called?
Correct Answer
C. Six, hexagon
Explanation
A snowflake has six sides, which gives it a hexagonal shape. This is because snowflakes are formed through the process of crystallization, where water molecules freeze and form a hexagonal lattice structure. Each side of the snowflake corresponds to one of the six arms or branches that extend outwards from a central point, creating its unique hexagonal shape.

What does it mean to be symmetrical?
