Scientific Method Steps
The first two steps of the scientific method
What are observation and question?
What is the purpose of a control group in an experiment?
What is to provide a baseline?
Name the two different types of variables?
what are independent and dependent variables?
Come up with a hypothesis for an experiment on if classical music affects the rate of plant growth
If classical music is played, then the plants will grow faster
In which step are you investigating your hypothesis?
What is an Experiment/ experimentation?
What is the difference between independent and dependent variables?
What is a dependent variable changes due to the independent variable and the independent variable remains unaffected by the dependent variable
In experiment about the growth of a plant in different light amounts, what is the independent variable?
what is the amount of sunlight
What is the control group and experimental group for the music experiment?
What is the plants growing without music and the plants growing while music is playing
What is a hypothesis?
Explain the importance of replication in an experiment
What is reliability of data and validity of the results.
In an experiment on the reaction time of a driver to a road block, what is the dependent variable?
What is the reaction time of the driver?
What are the independent and dependent variables in this experiment?
Independent: the presence or absence of music
dependent: the height of the plants/ rate of growth
In which step are students diving deep into the results of their experiment?
What is analyzing data and drawing conclusions?
How do you make an experiment more valid?
what is by increasing the number of replicates and number of participants
In a chemistry experiment, the students are testing the amount of oxygen released from a reaction where solute is added, what is the independent variable?
Name two controls that can be implemented to ensure the results are valid
There can be multiple: see what students say
what is the difference between an inference and observation?
An inference is when you conclude something from evidence and an observation is recording data
one way that a theory is different from an inference
what is that theories require A LOT of evidence
Why is it important to control variables in an experiment?
what is to test only one relationship
What are two ways the experiment can become more valid?
what is by increasing the number of replicates and number of plants
