What do plants need to grow?
What do plants need to grow?
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.

Sharon is doing a school project to see if plants must have both water AND sunlight to grow. She decides to put some plants in a window and others in a dark closet. She waters one in the sunshine and one that is in the dark. Sharon forgets to write down her observations and measurements when she studies the plants each day. She makes up the day, a conclusion, and turns it into her teacher. Can we trust Sharon's outcome, why or why not?

Sharon's conclusion cannot be trusted. She only did part of the investigation entirely, so she made up the data that she turned in and based her conclusion on. Conclusions need to be based on accurate and truthful data collection to be trusted. Sharon would have to repeat the investigation correctly to believe the new outcome.

Keith's plant was wilting and turning brown because it did not have any water for almost a whole week. Plants need both water and sunlight to grow and survive. His plant had sunshine and was still dying because plants must have BOTH to do well. Keith didn't mean to perform an investigation about this topic, but his real-world experience can help him to learn and answer a scientific question with evidence.

Hannah's mother gave her a sunflower plant for her birthday. She put it in the living room in a shady corner and watered it every day. She noticed it drooping and turning brown but could not figure out why. What was the most likely reason the plant was not growing and green?
Hannah's mother gave her a sunflower plant for her birthday. She put it in the living room in a shady corner and watered it every day. She noticed it drooping and turning brown but could not figure out why. What was the most likely reason the plant was not growing and green?
Hannah's plant was not growing, was drooping, and turning brown because it was not getting enough sunlight. Plant leaves use sunlight to help make food so they can grow and survive. If it was in a shady corner, it couldn't get the sunlight it needed. She did an excellent job of watering the plant but was missing the sunshine piece for survival.

Candy and Carly's mother gave them each a daisy plant to decorate their bedrooms. Candy put her plant on the windowsill, watered it every day, and checked for flowers and new leaves sprouting. Carly put her plant on a shelf in her room near the window and watered it once or twice a week. Candy's plant had beautiful white flowers and bright green leaves. Carly's daisy has no flowers, and the leaves were wrinkled. What was the most likely reason that Carly's plant had no flowers and had wrinkly leaves?

Carly's plant did not have flowers and had wrinkly leaves because it did not have enough water. Plant leaves use sunlight to help make food so they can grow and survive. It was in the sunshine, so it was able to make its food. What was missing was the water it needed to absorb nutrients from the soil. Plant roots absorb nutrients from the water and the dirt, and because it did not have enough water, it could not grow properly.

Plants can live without sunlight as long as they have water.
Plants can live without sunlight as long as they have water.
The statement in the question is false. Plants cannot live without sunlight, even if they have water available. If plants do not have water or sunlight, they will not survive. Plants need sunlight to make their food and provide them with nutrients to grow. Plants must have water and absorb it through their roots. Water and sunlight are two things plants MUST have to grow and live.

Justin wants to plan an investigation to see if a plant can live without sunlight or water. What list of materials is appropriate for this type of investigation?
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.

Brandon is curious about what keeps plants alive and helps them to grow. Which answer choice is a testable, scientific question that relates to the topic?
Brandon is curious about what keeps plants alive and helps them to grow. Which answer choice is a testable, scientific question that relates to the topic?
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.

Virginia is planning an investigation to test what would happen if she does not give rose plants sunlight or water. Her teacher tells her to state her hypothesis or prediction of what she thinks the results will be. Which hypothesis is most reasonable?
Virginia is planning an investigation to test what would happen if she does not give rose plants sunlight or water. Her teacher tells her to state her hypothesis or prediction of what she thinks the results will be. Which hypothesis is most reasonable?
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.

Jennifer wants to test whether plants can survive without sunlight and water. Which answer choice represents the BEST plan to investigate this?
Jennifer is testing whether plants can survive without sunlight and water, so those are the only two variables that will change. Everything else in the investigation should remain the same. The same pots, same dirt, same amount of water each day, same type of seeds, and the same amount of sunlight or darkness should be maintained throughout the investigation. "Get four identical pots and fill each with the same amount of dirt—plant three sunflower seeds in each container—place two in a window and the other two in a dark closet. Water one of the plants in the window daily, water one of the plants in the dark closet daily—record plant growth and observations." is the most controlled and complete investigational plan.

Nick is planning an investigation to see if plants grow better in the dark or somewhere sunny. Which data table set-up would be best for him to use during this investigation?
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.

Andrew wants to investigate if plants need water to survive. Which data table set-up is most appropriate for this investigation?
The only test variable in this investigation is whether the plant gets water or not. Andrew is testing if water is needed for plants to survive. All of the test plants should be in the same location, and some should get water while others do not so they can be compared to one another. If all the plants get water, then Andrew will not know what would happen without water. If he has some plants in different locations, he won't know if it is the water or the area that stopped a plant from surviving.

Morgan wants to investigate if plants need water AND sunlight to survive. Which data table set-up is most appropriate for this investigation?
Morgan has two test variables in her experiment. She wants to know if plants need water AND sunlight to survive. Morgan has to test both of these variables to see what plants need. The data table that best matches this investigation shows two plants in the sun and two plants in the dark. One plant from each group will get watered, and the other two will not. Morgan can collect information and observations about how the plants grow under each condition.

What does it mean to investigate?
To investigate something or to participate in an investigation means to discover, study, or research. When scientists have a question, they will come up with a plan to try and answer it. If someone wanted to investigate a plant's growth, they could test the type of soil, amount of water or sunlight, or the type of plant. They would collect data and make observations about the plants; this would be an investigation.
