Ross is conducting an investigation in which he has grown three bean plants in three different pots. Each pot is similar in size and contains the same amount and type of soil. He watered Pot 1 with 50 mL of water per day, Pot 2 with 70 mL of water per day, and Pot 3 with 100 mL of water per day. He put the pots on a sunny windowsill and measured the growth of each plant after a week. He recorded his observations.
Which question is Ross trying to answer through this scientific investigation?
How does the amount of water affect the growth of bean plants?
How does sunlight affect the amount of water absorbed by bean plants?
How does the amount of garden soil in which bean plants are grown affect their size?
How does the type of soil affect the growth of bean plants?
A student conducted a comparative investigation to test the hypothesis that different areas of New York City have different levels of air pollution.
Which is a likely benefit of this comparative investigation?
It provides her with a large amount of information about air pollution in New York City.
It requires that she observe a limited number of variables.
it provides her with results that are valid for a long time.
It allows her to learn about the causes and effects of air pollution in major cities.
Which statement best describes a benefit of conducting a comparative investigation over collecting data from the Internet?
A comparative investigation can be repeated in a short time while collecting the continuous data from the Internet takes longer.
Conducting a comparative investigation is always less expensive than an investigation in which data is obtained from the Internet.
Conducting a comparative investigation is always less time consuming than obtaining data from the Internet.
A comparative investigation can provide a wider range of data than can be obtained from the Internet.
A student wanted to know the most effective way to grow bacteria in a lab. He conducted a descriptive investigation instead of an experimental investigation.
What is a limitation of his investigation?
A descriptive investigation cannot show a cause-and-effect relationship between bacteria growth and possible factors affecting growth.
A descriptive investigation is always more expensive than an experimental investigation.
A descriptive investigation usually does not involve much data collection to support a hypothesis.
A descriptive investigation provides little prior knowledge or background information about bacteria growth.
Several students want to conduct a descriptive investigation on igneous rocks.
Which process is most likely to be part of their investigation?
