Buying the same type of water

Refilling a plastic water bottle. 

Correct answer:

Refilling a plastic water bottle.

Example Question #1 : 2nd Grade Science

Select the best example of a habitat for a fish. 

Possible Answers:

Ocean

Land

Dessert 

Forest

Ocean

Explanation:

A habitat is a home of a plant or animal. 

Fish live in water, so given the answer options the ocean is the best choice. A fish would not be able to survive in a forest, desert, or on land. 

Example Question #1 : Life Science

Select the best example of a habitat for an owl. 

Possible Answers:

Ocean 

Forest 

Sea

River

Correct answer:

Forest 

Explanation:

A habitat is a home of a plant or animal. 

An owl is a type of bird that lives in trees, which are found in forests. Owls could not survive in the sea, ocean, or river because they can't swim. Also, they eat rodents, which are not found in bodies of water. 

Example Question #1 : Life Science

Select the best example of a habitat for a whale. 

Possible Answers:

Forest

Ocean

Ocean

Explanation:

A habitat is a home of a plant or animal. 

Whales live in water, which means forest and desert are not the correct habitats for a whale. A pond is a small body of water, and most ponds are not very deep. Whales are large animals that require a lot of space, making ocean the best habitat a whale. 

Example Question #2 : Life Science

A deer is an animal that lives on the land, and they eat a lot of plants. They can't survive is very hot temperatures, which makes a desert a bad habitat for deer. Also, deers can't swim which would make an ocean and a river bad habitats for deer. 

Example Question #1 : Physical Science

Select the tool you would use to answer the question provided. 

How hot is the hot chocolate? 

Possible Answers:

Measuring cup

Ruler 

Thermometer 

Scale 

Correct answer:

Thermometer 

Explanation:

Let's take a look at the tools given in the answer choices:

A thermometer is used to measure the temperature of something, or to determine how hot or cold something is. 

A scale is used to determine the weight of an object. 

A measuring cup is used to determine the amount of something. Measuring cups are often used in baking. For example, if a recipe called for two cups of sugar, you would use a measuring cup to measure out two cups of sugar.  

A ruler is used to measure the length of something. 

Based on the question, we are trying to determine how hot the hot chocolate is, so we would use a thermometer.
