Scientific Method
What is the scientific method?
A systematic process scientists use to ask questions, gather data, and test hypotheses.
Pattern of investigation
What is the difference between a scientific law and a scientific theory?
A law describes what happens; a theory explains why it happens.
What is the following measurement?
50cm?
Length
Which axis does the independent variable go on?
The x-axis.
Name the last two steps of the scientific method.
Analyze data
Draw Conclusions
What is the base unit to measure mass of an item?
Grams
What is the following measurement?
800 cm3
Volume
Which axis does the dependent variable go on?
The y-axis
What is an independent variable?
The variable that is changed or tested in an experiment.
Convert 893 cm to meters.
8.93 m
What is the following measurement?
1.0 g/cm3
Density
What type of graph is best for showing changes over time?
A line graph.
What are the six steps of the scientific method in the correct order?
1. Ask a question
2. Do research
3. Form a hypothesis
4. Test with an experiment
5. Analyze data
6. Draw a conclusion/share results.
What is the base unit measurement for length?
Meters
If an object has a mass of 3 kg and a volume of 0.5 cm³, what is its density?
6 kg/cm³
What type of graph is best for comparing categories or groups?
A bar or pie/circle graph
Why is it important to control variables in an experiment?
So only the independent variable affects the outcome, making results valid.
Convert 9 m to millimeters.
9,000 mm
If an object has a volume of 5 cm3 and a density of 3 kg/cm3, what is it's mass?
15 kg
Why is it important to label the axes on a graph?
To clearly show what is being measured and compared, making the data easy to understand.
