What is the scientific method?
6 step method of investigating the
answer to a question.
True or False:
If we follow the scientific method carefully, then any scientists should be able to repeat what we did and get the same results.
True
The scientific method is a very special way of answering a:
A. Question
B. Problem
C. Song
Why do scientists use a hypothesis before doing an experiment?
A hypothesis gives scientists a prediction or educated guess about what will happen.
It helps guide the experiment.
What is a scientist?
Person who looks to answer a
question about something they can
observe using a specific method.
True or False: There are 7 steps in the scientific method.
False, there are 6.
After doing some research, we can come up with an
educated guess about what will happen called a:
A. Experiment
B. Hypothesis
C. story
B. Hypothesis
How do observations help scientists decide on their conclusion?
Observations show what actually happened.
Scientists use those facts to decide if their hypothesis was correct.
What is a hypothesis?
An educated guess about what you
think will likely happen in an
experiment.
True or False:
A hypothesis is what you do during the experiment.
False, it is what you THINK will happen during the experiment.
After we have a hypothesis, we run these to test it:
A. Experiments
B. Races
C. Video games
A. Experiments
Why is it important to only change one thing in an experiment?
It is important to only change one thing in an experiment so you know exactly what caused the result. If you change more than one thing, you won’t know which change made the difference.
What is an independent variable?
The thing a scientists changes from
one experiment to the next.
True or False: It is important that we study things that can be measured.
True
We want to make sure how many variables change at one time?
A. 6
B. 1
C. 4
B. 1
Why do we write down observations during an experiment?
So we don’t forget what happened and can use the facts to explain our results.
What is a controlled variable?
Things the scientist makes sure does
NOT change during the experiment.
True or False: The variables we want to be the same every time we run the experiment are called controlled variables.
True.
The variable we are actually watching for change is the:
A. Controlled
B. Scary
C. Dependent
C. Dependent
