Example Question #11 : Sunlight, Water, And Plant Growth
Gary is investigating whether plants need and sunlight to grow. He experimented, and the data table shows his results. Based on this info, what can be concluded about the plants' need for water and sunlight?
Plants that did not get both sunlight and water did not grow, and some did not survive.
Plants that got only sunlight did very well and had green leaves.
Plants that got both sunlight and water did not grow, and some did not survive.
Plants that did not get both sunlight and water grew very well and got taller.
Plants that did not get both sunlight and water did not grow, and some did not survive.
Collecting data and making observations during an investigation provides the information necessary to draw a conclusion. Based on the information provided, only "Plant 1" received water and sunlight, and it was the only plant that grew and looked healthy. The conclusion "Plants that did not get both sunlight and water did not grow, and some did not survive." is supported by the evidence provided.
Example Question #11 : Sunlight, Water, And Plant Growth
Susan is investigating whether plants need and sunlight to grow. She experimented, and the data table shows her results. Based on this info, which plant seemed to do the best and why?
Plant 4; this plant died, but it used to be green
Plant 2; the plant did not grow but it only had brown shriveled leaves and did not die
Plant 3; this plant had wilted, brown leaves but it didn't die
Plant 1; this plant was green and grew at the end of the investigation
Plant 1; this plant was green and grew at the end of the investigation
Collecting data and making observations during an investigation provides the information necessary to draw a conclusion. Based on the information provided, only "Plant 1" received water and sunlight, and it was the only plant that grew and looked healthy. The conclusion that Plant 1 did the best is supported by its appearance and the fact that it survived.
Example Question #1 : Investigate Whether Plants Need Sunlight And Water To Grow
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?
No; Sharon's data was made up so her conclusion was not based on evidence
Yes; Sharon set the investigation up correctly and was only missing the data portion which isn't even important
Yes; Sharon did most of the investigation correctly so that is good enough
No; Sharon's teacher has the information, so there is no way to tell if we can trust it
No; Sharon's data was made up so her conclusion was not based on evidence
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.
Example Question #1 : Investigate Whether Plants Need Sunlight And Water To Grow
Keith forgot to water his new plant for almost a whole week. When he checked on it, the plant was wilted, and the leaves were turning brown. He had it in the sunlight as the directions said, but it didn't look right. What happened to Keith's plant, and why?
His plant needed less water. The plant was dying because plants need sunlight and a tiny amount of water to live.
His plant needed less sunlight. His plant had everything else it needed but too much sunshine.
His plant needed water, and he did not provide it. The plant was dying because they must have sunlight and water to live.
His plant needed more sunshine. Plants don't do well when they are in the shade so it was dying.
His plant needed water, and he did not provide it. The plant was dying because they must have sunlight and water to live.
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.
Example Question #2 : Investigate Whether Plants Need Sunlight And Water To Grow
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?
It did not get watered.
It needed less sunlight.
It needed less water.
It needed more sunlight.
It needed more sunlight.
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.
Example Question #1 : Investigate Whether Plants Need Sunlight And Water To Grow
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?
It needed less water.
It needed more sunlight.
It needed more water.
It needed less sunlight.
It needed more water.
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.
Example Question #1 : Investigate Whether Plants Need Sunlight And Water To Grow
Debbie 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. Debbie wrote down her daily observations and measurements and created a data table to display the information. She concludes that the plants in the window that received water grew the tallest and had the healthiest appearance. Is her conclusion valid based on the information she gathered? What evidence supports her claim?
Debbie's conclusion is invalid. The plant may have grown two inches, but it did not flower or produce fruit, so it cannot be healthy.
There is no way to tell if Debbie's conclusion is valid with the evidence that is provided in the data table.
Debbie's conclusion is valid. The plant in the sunny location that was watered looked green and grew two inches during the investigation.
Debbie's conclusion is partially valid. The plant grew, but it does not appear to be healthy.
Debbie's conclusion is valid. The plant in the sunny location that was watered looked green and grew two inches during the investigation.
Collecting data and making observations during an investigation provides the information necessary to conclude. Based on the information provided, only "Plant 1" received water and sunlight, and it was the only plant that grew and looked healthy. The conclusion that Plant 1 did the best is supported by its appearance and the fact that it survived. Debbie's conclusion is valid. The plant with access to sunshine and water is the most healthy in appearance and the only plant that grew.
Example Question #3 : Investigate Whether Plants Need Sunlight And Water To Grow
Plants can live without sunlight as long as they have water.
False
True
False
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.
Example Question #31 : 2nd Grade Science
Susan is investigating whether plants need and sunlight to grow. She experimented, and the data table shows her results. Based on this info, which plant seemed to do the worst and why?
Plant 1; this plant was green and grew at the end of the investigation
Plant 2; the plant did not grow, but it only had brown shriveled leaves and did not die
Plant 3; this plant had wilted, brown leaves but it didn't die
Plant 4; this plant died
Plant 4; this plant died
Collecting data and making observations during an investigation provides the information necessary to conclude. Based on the information provided, "Plant 4" did the worst because it died. "Plants 2 and 3" did not grow and have brown leaves, so they did not do well but are still alive. "Plant 4" had no sunlight or water, so it had none of the necessary elements for growth or survival.
Example Question #5 : Investigate Whether Plants Need Sunlight And Water To Grow
Gary is investigating whether plants need and sunlight to grow. He experimented, and the data table shows his results. Based on this info, what can be concluded about the plants' need for water?
Plants that got both sunlight and water did not grow, and some did not survive.
Plants that got only sunlight did very well and had green leaves.
Plants that did not get water did not grow, and some did not survive.
Plants that got only water did very well and had green leaves.
Plants that did not get water did not grow, and some did not survive.
Collecting data and making observations during an investigation provides the information necessary to conclude. Based on the information provided, only "Plant 1" received water and sunlight, and it was the only plant that grew and looked healthy. "Plants 2 and 4" did not receive water, and they did not grow. "Plant 2" had brown shriveled leaves, and "Plant 4" died. Without water, plants cannot survive.
