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.

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.

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.

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. 

For plants to grow and survive, they need sunlight and water. Water is collected through the roots of the plant and absorbed from the soil. Sunlight is collected through the leaves of the plant to use in the process of photosynthesis to make food. Plants cannot live without sunlight and water.

If Justin wants to plan an investigation, an important part is to have the right supplies or materials. Justin will need two plants, one to place in the sunlight and one in the dark, water for the plant in the sunshine, a ruler to measure growth, and paper and pencil to record observations. The other lists are incomplete or have materials that are not needed for this investigation.

Most investigations or experiments start with a question. In this case, Brandon is wondering about keeping plants alive and helping them grow. A scientific question must be testable, meaning someone can collect data and observations, and it should be related to what the person was wondering. The correct answer choice is testable and related. Water and sunlight are essential to a plant's survival, so they would be good variables to test.

A hypothesis is stated before an investigation or experiment is performed, and the evidence collected will either support or will not support the prediction. A hypothesis should be reasonable and related to the topic. Virginia is testing what would happen to plants without water or sunlight; these are two critical pieces to a plant's survival. Using background knowledge or personal experiment, a prediction can be made that the plants will not survive. "I believe the rose plants will not survive without sunlight or water. They will wilt and die over time." is the most reasonable hypothesis.

In this investigation, Nick is only testing if plants grow better somewhere dark or sunny. The water the plants receive should be the same, and there should be some plants in the sun and some in the dark so they can be measured and observed. There have to be plants in both locations to compare growth.

The best title for Christopher's experiment would be "Do Plants Need Sunlight and Water to Grow?". It is short and includes all of the vital information. It doesn't leave anything out or have any parts that are irrelevant to the experiment.
