Example Question #1 : Plan An Investigation To See Whether Plants Need Sun And Water
What do plants need to grow?
Possible Answers:
Moonlight and wind
Sunlight and water
Water and wind
Sunlight and moonlight
Correct answer:
Sunlight and water
Explanation:
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.
Water, two plants, a window, a dark closet, a pencil, paper, and a ruler
Correct answer:
Water, two plants, a window, a dark closet, a pencil, paper, and a ruler
Explanation:
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.
Example Question #3 : Plan An Investigation To See Whether Plants Need Sun And Water
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?
Possible Answers:
What would happen if plants did not receive water or sunlight?
Which plant, the rose bush or sunflower, grows the tallest?
How many different plants are there in a garden?
Which plant is the prettiest, the daisy, or lilac?
Correct answer:
What would happen if plants did not receive water or sunlight?
Explanation:
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.
Example Question #4 : Plan An Investigation To See Whether Plants Need Sun And Water
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?
Possible Answers:
"I believe the rose plants will start to die but then come back to life. They will survive and grow tall."
"I believe that the rose plants are prettier than most other flowers, so they will be fine."
"I believe the rose plants will not survive without sunlight or water. They will wilt and die over time."
"I believe that the rose plants will bloom beautiful flowers and have tall green stems."
Correct answer:
"I believe the rose plants will not survive without sunlight or water. They will wilt and die over time."
Explanation:
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.
Example Question #5 : Plan An Investigation To See Whether Plants Need Sun And Water
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?
Possible Answers:
Correct answer:
Explanation:
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.
Example Question #6 : Plan An Investigation To See Whether Plants Need Sun And Water
Christopher is planning an investigation to see whether plants need sunlight and water to grow and survive. Which title would be best for his experiment?
Possible Answers:
"Do Plants Need Water to Grow?"
"Do Plants Need Sunlight to Grow?"
"Do Plants Need Sunlight and Water to Grow?"
"Do Plants Need Sunlight and Water to Grow More Than One Foot Tall?"
Correct answer:
"Do Plants Need Sunlight and Water to Grow?"
Explanation:
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.
Example Question #7 : Plan An Investigation To See Whether Plants Need Sun And Water
Jennifer wants to test whether plants can survive without sunlight and water. Which answer choice represents the BEST plan to investigate this?
Possible Answers:
Get two identical pots. Fill one with dirt from the yard and fill the other with soil from the store—plant three sunflower seeds in one and three lima bean seeds in the other. Place one in the window and one in a dark room. Water the plant in the dark room daily and record the plant growth and observations.
Get two identical pots. Fill one with dirt from the yard and fill the other with soil from the store. Plant three sunflower seeds in each container. Place them both in a dark room, water the plants daily, and record plant growth and observations.
Get six identical pots and fill each with the same amount of dirt—plant three sunflower seeds in each container. Place two in the window, two in a dark room, and two outside. Water all six plants daily and record plant growth and observations.
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.
Correct answer:
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.
Explanation:
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.
Example Question #8 : Plan An Investigation To See Whether Plants Need Sun And Water
Andrew wants to investigate if plants need water to survive. Which data table set-up is most appropriate for this investigation?
Possible Answers:
Correct answer:
Explanation:
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.
Example Question #9 : Plan An Investigation To See Whether Plants Need Sun And Water
Morgan wants to investigate if plants need water AND sunlight to survive. Which data table set-up is most appropriate for this investigation?
Possible Answers:
Correct answer:
Explanation:
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.
Example Question #10 : Plan An Investigation To See Whether Plants Need Sun And Water
What does it mean to investigate?
Possible Answers:
A sleeveless, close-fitting waist-length garment worn over a shirt
To discover, study, or research something
A hinged barrier used to close an opening in a wall or fence
To place money into an account hoping to make more later
Correct answer:
To discover, study, or research something
Explanation:
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.
