Scientific Method
A series of steps designed to help you solve problems and answer questions
A) scientific method
B) experiment
C) hypothesis
D) observation
A) scientific method
This is the first step of the scientific method?
Asking a question
If you changed two things at once, this would happen to your results.
The experiment would not be a fair test
The information (evidence) gathered from observations and experimentation is called
Data
Scientists are the only individuals who use the scientific method True or False
False - WE ALL USE IT
What is the last step of the scientific method?
Conclude/Conclusion
What is a hypothesis?
An educated guess or prediction of what you think the outcome will be
Unchanged, used as the comparison in an experiment
Control
What type of data is Numerical Data and Measurements
Quantitative
A good science fair question should be something you can ______.
Test or measure
What 2 words should guide your hypothesis statement?
If, Then
This step is when you actually test your hypothesis.
Conducting an experiment
what changes as a result of the independent variable manipulation in experiments (what we measure)
dependent variable.
A graph that shows data over time
line graph
The person who explains their project to judges and visitors.
Student scientist
Gathering information by using your senses is called
Observations
This shows your data visually using bars, lines, or pictures.
graph or chart
the variable you manipulate, control, or vary in an experimental study to explore its effects
A. | Dependent |
B. | Independent |
C. | Control |
D. | Uncontrolled |
B- Independent
evidence or arguments that are used to contradict, disprove, or counter the claim
Rebuttal
Making sense of the data, looking for patterns, finding trends, etc. is what scientist do. What is it called?
Analyzing
Data, details, and facts that support your claim (hint: don't use any of the words used in this question)
Evidence
Data collected using descriptions not numerical values (e.g., color, texture, smell)
qualitative data
A scientist conducted an experiment to determine how the amount of salt in a body of water affects the plant that can live in the water. In this experiment the independent variable is
the amount of salt in the water
Different preservatives were tried in foods to determine which best restricted the growth of molds. What is the dependent variable?
Growth of Mold
Scientists change their ideas when new evidence is discovered. This shows that science is always ______
Changing / Evolving
