A greenhouse is building where plants can be grown. It has walls that allow light and air inside. The amount of water and nutrients the plants receive can be controlled. Which is the best way for a farmer to make a greenhouse a good model for testing how crops will grow in a large field?

He could recreate the soil and water conditions of the field in the greenhouse.

Jillian made a model of an animal cell. She used a round balloon to represent the cell membrane. She pushed objects like marbles and rocks into the balloon to show cell parts, then filled it with water to show fluid inside the cell. What is a limitation of Jillian's cell model?

It does not show the functions of the cell parts.

A _____ is a simplified representation of a real object or system.

model

What might be one limitation of using a greenhouse as a model to represent a large farm?

A greenhouse is not exposed to the same weather patterns as a large farm.

Which examples are ways that models can help scientists solve problems? Select all that apply.

A model can represent something very large like the solar system. A model can represent something very small like a single cell. A model can represent something very complex like the flow of energy in an ecosystem. A model can represent something that cannot be seen or touched.

You are a biologist who is studying athletic performance. Your lab equipment includes a wind machine, stopwatches, and computers. Describe how you might use that technology to analyze this following problem: How is a runner's speed affected by wind?

I would set up the wind machine so it was blowing against people running. I would have it blow at different speeds in different trials. I would use a stopwatch to record the time of each trial for the runners. I would use the computer to help analyze the data from the trials.

Which best describes the relationship between science and technology?

Technology uses scientific knowledge to create solutions to real-world problems.
