Chapter 1 Test Review

A series of steps followed to solve problems is:

• Investigations

• The scientific method

• Standard procedures

• Experimental guidelines

A conclusion based on the basis of evidence and reasoning is a/an:

• Conlusion

• Hypothesis

• Inference

• Theory

A scientist who wants to study the effects of fertilizer on plants sets up an experiment. Plant A gets no fertilizer, Plant B gets 5 mg of fertilizer each day, and Plant C gets 1 mg of fertilizer each day. Which plant is the control group?

• Plant A

• Plant B

• Plant C

• All of them

In which step of the scientific method do we want to use graphs?

• Analyze data

• Make a hypothesis

• Report conclusions

• Make an observation

When a scientist shares their findings with other scientists, they are:

• Communicating results

• Experimenting

• Making a hypothesis

• Analyzing data

When you decide whether or not the data supports the original hypothesis, you are:

• Making observations

• Drawing conclusions

• Asking questions

• Forming a hypothesis

The process of obtaining information by using the senses is called a/an:

• Inquiry

• Scientific method

• Conclusion

• Observation

A scientist hypothesizes that the temperature at which an alligator's egg is incubated will determine whether the alligator will be male or female. The independent variable is:

• The temperature

• The male alligators

• The gender of the alligator

• The incubator

A scientist hypothesizes that the temperature at which an alligator's egg is incubated will determine whether the alligator will be male or female. The dependent variable is:

• The temperature

• The size of the baby alligators

• The gender of the baby alligators

• The incubator

Choose the correct order of the scientific method.

• Observation, Hypothesis, Experiment, Analyze data, Conclusion, Make another hypothesis

• Hypothesis, Experiment, Conclusion, Observation, Analyze data, Make another hypothesis

• Observation, Hypothesis, make another hypothesis, Experiment, Analyze data, Conclusion

• None of the above
