Experiment.
What step of the scientific method do you test your hypothesis?
Experiment.
This type of observation is measurable/describes an amount.
Quantitative Measurement.

Providing a why/or explanation.
Which variable in measured in an experiment?
Dependent Variable.
In which step of the scientific method do you use your information to draw conclusions about your experiment?
Coming to a conclusion
What step in the scientific method do you make observations?
Gathering background information
This type of observation is an adjective/a descriptor.
Qualitative Measurement.

If you increase the amount of milk you drink, then you will increase the strength of your bones.
What variable changes in the experiment?
Independent Variable.
The ________________ involves a series of steps that are used to investigate a natural occurrence.
Scientific Method.

Step 6, share results.
Blue, rough, metal are all examples of what type of observation?
Qualitative Measurement.
I wonder if increasing the amount of coffee I drink during the day will give me more energy? State a good hypothesis for this question.
If you increase the amount of coffee you drink, then your energy will increase throughout the day.

Control.
List the independent and dependent variables in the following hypothesis. If soil temperatures rise, then plant growth will increase.
Independent-soil temperatures, Dependent-plant growth.
List all six steps of the scientific method.
Question, Gather background info, Hypothesis, Experiment, draw a conclusion, share Results.
4 feet long with 24 buttons are both examples of what type of observation?
Quantitative Measurement.
Read the following experiment and state a good hypothesis. I am doing a test to see if there is a connection between how long you run and how fast your heart beats. I will be performing an experiment where a person will run for a 1 minute and I will check their heartbeat. Then they will run for 2 minutes and I will check their heart rate. I will do this up to 6 minutes and see if there is a connection. What do you think my hypothesis should be?
If I increase the amount of time I run, then my heartbeat will increase.
Find the independent and dependent variables in the following experiment: If you increase the number of times you practice shooting free-throws, then you will increase your chances of making a basket every time.
Independent- practice shooting free throws, Dependent- making baskets.
Thinking about the hypothesis: If soil temperatures rise, then plant growth will increase. What might a control in this experiment be?
using the same potting soil, making sure both plants have an equal amount of light, using the same type of plant etc.
