Scientific Method
What is the first step in the scientific method?
Identify the problem/ask a question
What are the two types of observation?
Objective and Subjective
What are the two types of variables stated in a hypothesis?
Independent and Dependent.
Which step of the scientific method is missing: Question, Collect information, Formulate a Hypothesis, ______________, Analyze Results, Share the Results/Make a Conclusion
Experiment
What step of the scientific method do you test your hypothesis?
Experiment
This type of observation is measureable.
Objective Observation
What is the responding variable that may or may not change due to manipulation?
Dependent Variable.
In which step of the scientific method do you use your information to draw conclusions about your experiment?
Analyze Results.
What step in the scientific method do you gather background information?
Collect information
This type of observation is describable.
Subjective Observation
If you drink more milk will you get stronger bones? Turn this statement into a well-spoken hypothesis.
If you increase the amount of milk you drink, then you will increase the strength of your bones.
What is the term we use to describe the manipulated variable that the experimenter intentionally changes?
Independent Variable.
The ________________ involves a series of steps that are used to investigate a natural occurrence.
What is Scientific Method.
Blue, rough, metal are all examples of what type of observation?
Objective Observation
I wonder if plants grow faster when they listen to music? Please turn this question into a well-spoken hypothesis.
If I play (amount of time/type of) music, then my tomato plants will grow twice as fast.
In an experiment what do we call the group of individuals or objects that are not manipulated and used only for comparison.
The control group
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 (IN ORDER)
1.Ask a question/identify the problem
2. Collect information
3. Create a hypothesis
4. Experiment/Test your hypothesis
5. Analyze the data
6. Make your conclusion/report your findings
The fish was smelly, ugly, and looked dangerous. This description lists what kind of observations?
Subjective observations
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 constant in this experiment be?
using the same potting soil, making sure both plants have an equal amount of light, and are watered the same amount as well.
