What is used to test a hypothesis
An Experiment
A Question
A Conclusion
A Hypothesis
Which of the following is an example of a hypothesis
Go to the lab table and take a beaker, water, and dye.
Do plants need water to grow?
the grass will grow more in a dark environment
A beaker, a microscope and a ruler
Which of the following is an example of a hypothesis
Enzymes speed up chemical reactions
The more water plants get the more they will grow
Do you think I need to add water to the beaker?
First complete the chart, then graph the material
An educated guess or prediction is known as what?
A Conclusion
Dependent Variable
Independent Variable
Hypothesis
Is found on the x-axis of a graph
A Conclusion
Dependent Variable
Independent Variable
Hypothesis
This is what the experimenter is changing in a well designed experiment
A Conclusion
Dependent Variable
Independent Variable
Hypothesis
Is found on the y-axis of a graph

Dependent Variable
Independent Variable
Hypothesis
This may or may not change when conducting a well designed experiment.
A Conclusion
Dependent Variable
Independent Variable
Hypothesis
This is that data that is collected during an experiment

Experiment
A scientist wants to see if temperature impacts the amount of enzyme present. What would be a valid hypothesis for this experiment?
If there is more enzyme the temperature would increase
I think that I want to test the enzymes
If the temperature increases then their would be more enzymes present
Enzymes and temperature
A scientist wants to see if temperature impacts the amount of enzyme present. What would be the independent variable for this experiment?
Amount of Enzyme Present
change in pH
Temperature
Amount of bacterial growth
A scientist wants to see if temperature impacts the amount of enzyme present. What would be the dependent variable for this experiment?
Amount of Enzyme Present
change in pH
Temperature
Amount of bacterial growth
A scientist wants to see if temperature impacts the amount of enzyme present. How would the control group be treated differently from the experimental group?
the control group would stay the same
There would be no change
the control group would have a different temperature than the experimental groups
The control group would have a different amount of enzyme than the experimental groups
A scientist wants to see if exercise has an impact on the rate at which you can squeeze a clothespin. What would be a valid hypothesis
The more you exercise, the faster your heart will beat
The more you squeeze a clothespin will make you exercise less
The more you squeeze a clothespin the more your heart will beat.
The more you exercise the less you would squeeze a clothespin
A scientist wants to see if exercise has an impact on the rate at which you can squeeze a clothespin. What would be the independent variable?
The amount of time
The amount of exercise
The number of squeezes of the clothespin
The location
A scientist wants to see if temperature impacts the amount of enzyme present. What are 2 factors that should remain the same in order to have a well designed experiment?
the Temperature & the amount of time testing
Amount of bacterial growth & temperature
amount of time testing & the type of enzyme
the amount of enzyme and the pH
A scientist wants to see if temperature impacts the amount of enzyme present. How would we make this experiment more valid?
Change the hypothesis
repeat the experiment
Add more independent variables
Create a graph of the results
A scientist wants to see if exercise has an impact on the rate at which you can squeeze a clothespin. What would be the dependent variable?
The amount of exercise
The amount of time
The number of squeezes of the clothespin
The location
A scientist wants to see if exercise has an impact on the rate at which you can squeeze a clothespin. How would you increase the validity of the experiment?
Increase the time for one group
Make a chart to keep track of your data
Change the experimenter
Add more experimental groups
A scientist wants to see if exercise has an impact on the rate at which you can squeeze a clothespin. How would the control group be treated differently from your experimental group?
Change the experimenter
The control group would not exercise
Increase the time for one group
Make a chart to keep track of your data
A scientist wants to see if exercise has an impact on the rate at which you can squeeze a clothespin. What are 2 variables that should remain the same?
the experimenter & the type of clothespin
the environment and the experimenter
The amount of time for rest/exercise and the experimenter
Type of clothespin being used and the amount of time for rest/exercise
