### Example Question #1 : 2nd Grade Science

Select the time that could be when the sun rises.

Explanation:

The sun rises in the morning. Looking at our answer choices, we have times that are in  and .

Times that are in  are morning times. Times that are in  are afternoon and evening times.

Because the sun rises in the morning, our answer choice needs to end in

is the middle of the night, and the sun is not out in the middle of the night.  is a morning time and the sun could rise around

### Example Question #2 : 2nd Grade Science

Select the time that could be when the sun sets.

Explanation:

The sun sets in the evening. Looking at our answer choices, we have times that are in  and .

Times that are in  are morning times. Times that are in  are afternoon and evening times.

Because the sun sets in the evening, our answer choice needs to end in

is the middle of the night, and the sun is not out in the middle of the night.  is a morning time so the sun would not be setting.  is the middle of the afternoon, when the sun is at its highest point, which means that the sun would not be setting.

could be a time that the sun is setting.

### Example Question #3 : 2nd Grade Science

Select the time that the sun is at its highest point.

Explanation:

The sun is at it's highest point during the afternoon, around

Around  the sun is just rising, so it's at one of its lowest points.

Around  the sun is setting, so it's at one of its highest points.

is the middle of the night, so it the sun is not up because it's dark.

### Example Question #4 : 2nd Grade Science

Select the example of reusing an object.

Throwing away a water bottle

Refilling a plastic water bottle.

Buying the same type of water bottle

Buying the same type of water

Refilling a plastic water bottle.

Explanation:

When you reuse something, you use something again.

Once you are done drinking a bottle of water, if you throw it away you aren't going to reuse it. But, if you refill the water bottle, that is an example of reusing the bottle.

Re-buying the same type of water or water bottle is not an example of reusing something. You are just buying the item again.

### Example Question #1 : Earth And Space Science

Water exists as solid ice and in liquid form.

False

True

True

Explanation:

The statement is true; water can be found on Earth in solid and liquid form. Water can be found on Earth in a solid form in cold areas as ice. Water can be found in a liquid form in places such as ponds, oceans, rivers, and more.

### Example Question #2 : Earth And Space Science

Why is water on Earth in both the solid and liquid state?

Water on Earth is neither a liquid nor a solid. It can only be a gas.

Water can be a solid or liquid depending on the temperature and conditions of its location.

Water on Earth is only in a liquid form and cannot be found in a solid-state.

Water can be a solid or liquid state, depending on what humans are doing to it. Nature cannot control water, only humans.

Water can be a solid or liquid depending on the temperature and conditions of its location.

Explanation:

Water on Earth can be found in both the liquid and solid states depending on the temperature and conditions of the environment it is in. In a hot place like the desert, water will not be found in a solid form as ice; it would be a liquid. In somewhere that is below freezing, one would likely see frozen water known as ice. In conditions such as a thunderstorm, both liquid and solid ice can be found it there is rain and hail.

### Example Question #3 : Earth And Space Science

Which photo represents water in a liquid form?

Explanation:

Water on Earth can be found in both liquid and solid states. Three of the photographs show water in the solid form - the mountain is covered in snow, which is solid, the ice cubes and icicles are frozen water. The only photo that demonstrates water in a liquid form is the drops on the window.

### Example Question #4 : Earth And Space Science

How could water be changed from its liquid form on Earth to a solid form?

It could be buried.

It cannot be turned from a liquid to a solid.

It could be frozen.

It could be melted.

It could be frozen.

Explanation:

Water can be changed from a liquid to a solid by freezing it. Many times ponds and lakes become frozen over when temperatures drop, and the liquid water is turned to ice. In the wintertime in many places, instead of rain falling from the clouds, we see snow because the temperatures are freezing and the water freezes.

### Example Question #5 : Earth And Space Science

Kaitlyn is looking to match different forms of water to images for a project. Which photo shows water in a solid form?

Explanation:

Water can be found in a liquid or solid state on Earth. The photo that represents a solid-state of matter is the ice and glaciers. These are large bodies of frozen water. The waterfall, ocean wave, and bottled water are all in a liquid form.

### Example Question #1 : Explain How Water On Earth Can Be Solid Or Liquid

Which answer choice is an example of solid and liquid water on Earth?

Solid - waterfall

Liquid - rain

Solid - rain

Liquid - waterfall

Solid - hail

Liquid - rain
