Steps of the Scientific Method
The first step of the Scientific Method is?
Problem or Question
A factor in an experiment that can change is a(n)____.
Variable
What should you do if your data does not match your hypothesis?
Change your hypothesis and try again.
In a controlled experiment, one piece of bread is placed in the refrigerator and one piece of bread is left on the counter. Observation of the bread is made over time and record is taken when it starts to mold. Measuring the time it molds is an example of a(n)
Dependent Variable
The second step, after problem and question, is?
Form a hypothesis
A sample that is kept constant and is not changed is a(n) ____.
Controlled Variable
Scientists test hypothesis by ________
doing an experiment
What should you do if you observe a problem or have a question about something?
Create an experiment.
In a controlled experiment, one piece of bread is placed in the refrigerator and one piece of bread is left on the counter. Observation of the bread is made over time and record is taken when it starts to mold. The same type of bread was used for the experiment. This is an example of a(n)
Controlled Variable
The third step, after form a hypothesis, is?
Measurements of the heights of various plants in an experiment could be an example of ___.
a dependent variable
Scientists need to make a very detailed procedure. Why?
So that it can be replicated by other scientists
What should you do if more than one variable is changed in an experiment?
Stop and restart by changing one variable.
In a controlled experiment, one piece of bread is placed in the refrigerator and one piece of bread is left on the counter. Observation of the bread is made over time and record is taken when it starts to mold. The location of the bread describes the ______ Variable.
Independent
The 4th step after creating a controlled experiment is?
Analyzing Data/Results
A variable that is purposefully changed to create a controlled experiment.
Independent Variable
A scientist has written a conclusion based off their years of experiments. What should they do with it?
Share it for other scientists.
What should you create if you have an educated guess as to why something is happening.
Create a hypothesis
In a controlled experiment, a scientist is studying how long it takes parachutes of different sizes to fall to the ground. What is the independent variable?
the different sizes of the parachute
The last step of the scientific method is?
Draw a Conclusion
What is the main difference between a control variable and an experimental variable.
Controlled is not changed and the experiment is changed to learn something new.
After a scientist has concluded that something is real. It is accepted as a _______ because it is supported by data.
theory
What should you do when you complete an experiment?
Do it again, and again, and again, and again.
An experiment is created that has five different plants that is put out in the sun. Observations are made by looking at the height of the plant. What are three controlled variables you should have?
...
