Scientific Method
What is the first step in the scientific method?
What is Question.
What do we use to make careful observations?
Our senses.
What step of the scientific method do you predict a possible answer to a problem or a question?
What is Hypothesis.
What are the two types of variables stated in a hypothesis?
What is Independent and Dependent.
Which step of the scientific method is missing? Question, Formulate a Hypothesis, ______________, Observe and Record Data, Analyze Results, Draw Conclusions, Share the Results
What is Experiment?
Which sense should you never use when experimenting in a science lab?
The sense of taste.
When using the scientific method, does it matter if your hypothesis is correct? Explain.
No.
What is the responding variable or factor that may or may not change due to manipulation?
What is Dependent Variable.
In which step of the scientific method do you use your data to analyze and figure out why you got your results?
Draw conclusions.
When you make observations and write down what occurred.
What is data?
Why is it important to make very careful observations when experimenting?
So your data is accurate.
If you drink more milk will you get stronger bones? State a good hypothesis for this question.
What is...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 or factor that the experimenter intentionally changes?
What is Independent Variable.
The ________________ involves a series of steps that are used to investigate a natural occurrence.
What is Scientific Method.
Why is it important to have as many trials as possible when experimenting?
The more data you have, the more accurate your data is.
I wonder if you smoke more cigarettes, will you have a better chance of getting lung cancer? State a good hypothesis for this question.
What is...If you increase the number of cigarettes you smoke, then you will increase your chance of getting lung cancer.
In an experiment what are the things that are not being studied that are held constant (the same) so that they do not influence the experimental outcome called?
What is a Control.
List the independent and dependent variables in the following hypothesis. If soil temperatures rise, then plant growth will increase.
What is...Independent-soil temperatures, Dependent-plant growth.
Give an example of how you can display your data in an organized manner.
A chart, graph, take pictures, draw pictures.
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.
Find the independent and dependent variables in the following experiment: Will playing different types of music for plants affect the plant growth?
What is Independent- various music types
Dependent- plant growth
Thinking about the hypothesis: If soil temperatures rise, then plant growth will increase. What might a control in this experiment be?
What is... using the same potting soil, making sure both plants have an equal amount of light etc.
