Collect data
What step of the scientific method do you test your hypothesis?
Experiment
This type of data is measureable.
Quantitative
Putting my plant in the closet will decrease it's chance of living. What is wrong with this hypothesis?
it is missing "If" and "Then"
What is the responding variable or variable that you are measuring?

one
Is this a testable or non testable scientific question- Is it better to be kind or smart?
Non testable
This type of data is describable/a category
Qualitative

What is the difference between a testable and non testable question?
A testable question can be answered through and experiment and collecting data, while a non testable question is based on beliefs and opinions
In which step of the scientific method do you present your experiment, observations and conclusions to other people?
Share results

Control variables
List the independent and dependent variables in the following hypothesis. If soil temperatures rise, then plant growth will increase.

List all seven steps of the scientific method.
Observation, Ask a question, Form a hypothesis, Test your hypothesis, Data, Conclusion, Share results
Running laps in 2 min, 2 min 10 secs, and 2 min 45 secs are examples of what kind of data?
Quantitative
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?
What is...If I increase the amount of time I run, then my heartbeat will increase.

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 etc.
