How does temperature affect the speed of an enzyme reaction?

A dependent variable...

• ...is the things that you want to remain constant.

• ...is the variable that you are changing.

• ...is what you measure as it changes.

The independent variable...

• ...is the variable you need to stay constant.

• ...is the variable you are in control of.

• ...is the variable that you measure as they change during the experiment.

A control variable...

• ...is the things that you want to remain constant.

• ...is the variable that you are changing.

• ...is what you measure as it changes.

What is the definition of a hypothesis?

• A possible coincidental explanation for experimental results.

• A result that doesn't conform to a pattern from the other results.

• A relationship between two variables.

• A possible explanation to be tested experimentally.

What was the hypothesis you were testing?

• As the temperature increases, the rate of reaction decreases.

• Temperature has no effect on the speed of the reaction.

• As the temperature increases, the rate of reaction increases.

What is the definition of a correlation?

• A possible coincidental explanation for experimental results.

• A result that doesn't conform to a pattern from the other results.

• A relationship between two variables.

• A possible explanation to be tested experimentally.

What is the definition of an anomalous result?

• A possible coincidental explanation for experimental results.

• A result that doesn't conform to a pattern from the other results.

• A relationship between two variables.

• A possible explanation to be tested experimentally.

What is the name of the enzyme that breaks down starch?

• Helicase

• Lipase

• Protease

• Amylase

What is the role of a control variable in an experiment?

• To measure the effect of the independent variable

• To ensure the experiment runs smoothly

• To keep conditions constant to allow a fair test of the independent variable

• To provide a variable for comparison

When drawing a graph of your results, which variable goes on the x-axis?

• Dependent

• Independent

• Control
