Scientific Method
What is the first step in the scientific method?
Ask a question/define a problem
What are the two types of observation (data)?
Qualitative and Quantitative
What is a hypothesis?
What you think the answer is based on your gathered information and prior knowledge, educated guess, predication based on knowledge
What are the two types of variables involved in an experiment?
Independent and Dependent.
Which step of the scientific method is missing: Question, Research Background Information, Formulate a Hypothesis, ______________, Observe Analyze Results, Conclusion/Share the Results
Controlled Experiment.
What step of the scientific method do you test your hypothesis?
Controlled Experiment.
What is the responding variable or factor, the data you are collecting during the experiment
Dependent Variable.
What does it mean to reject your hypothesis?
To state that your data does not support your guess and that you were incorrect.
What step in the scientific method do you make careful observations and write down what happens?
Make Observations and Record Data
If you drink more milk will you get stronger bones? State a good hypothesis for this question.
If you increase the amount of milk you drink, then you will increase the strength of your bones.
What is the difference between a control and an experimental group?
Control group is your baseline (normal) and does not change, the experimental group is manipulated to see the effect of the tested variable
The steel wool has a rough texture is an example of
qualitative data/observation
What do we call the process of repeating the same experiment over and over again to see if the results were valid and the same each time?
Verification
In an experiment what are the variables that are not changed as to not affect the results of the experiment?
Constants
List all six steps of the scientific method.
What is Question, Research, Hypothesis, Experiment, Observe and Analyze, Draw Conclusions/Share Results
What is an example of quantitative data?
Answers may vary
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.
