MI Midterm Rw- Risk Factors, Skin Cancer, & Experimental Design

The parts of the experiment that must be kept the same to avoid impacting the results.

In this graph, ​ time is the ​ (a)   while number of deer is the ​ (b)   ? 

What graph should be used in the following scenarios?

Two students test the effect of temperature on chemical reaction rate.

• -Student A tests 10°C, 20°C, and 30°C.

• -Student B tests 5°C,, 10°C, 15°C, 20°C, 25°C, and 30°C.

Which conclusion is best supported?

Experimental Data Analysis- A graph shows that as light intensity increases, plant growth increases until a point, after which growth decreases.

Place the risk factor examples into their correct category:

Match the following parts of the experiment: Sophia became interested in insulation while her parent’s new house was being built. She decided to determine which insulation transferred the least amount of heat. She filled each of 5 jars half-full with water. She sealed each jar with a plastic lid. Then she wrapped 4 of the jars with a different kind of insulation, leaving one jar without insulation. She put the jars outside in the direct sunlight. Later, she measured the temperature of the water in each jar.

In a well designed experiment, you should change how many variables?
