Thinking Scientifically

This step of the scientific method involves making an educated guess about what will happen

• Purpose/Question

• Experiment

• Hypothesis

• Conclusion

The variable that you are measuring in the experiment (responding variable).

• Independent

• Dependent

• Controlled/Constant

Data that includes numbers (measurements and amounts).

• Quantitative observations

• Qualitative observations

Which step of the scientific method is this example-

Does the volume of water change when it freezes?

• Hypothesis

• Research

• Conclusion

• Purpose/Question

What is the independent (manipulated) variable in the data table pictured?

• Pots A and B

• Water per day

• Height

• Mass

What is the last step of the scientific method where the hypothesis is stated as correct or incorrect?

• Analysis

• Experiment

• Purpose/Question

• Conclusion

You should test more than one variable at a time when doing an experiment

• True

• False

If you increase the amount of spinach you eat, then you will increase the iron in your blood.

What is the dependent variable?

• The amount of spinach

• Amount of iron in your blood

Metal + Acid =

• Alkali

• Explosion

• Salt amd Oxygen Gas

• Salt and Hydrogen Gas

Mg + HCL =

• MgH + Cl2

• MCl + gH2

• Mg + O2

• MgCL2 + H2
