Steps of Scientific Method
What is the first step in the scientific method?
State the question or problem.
What are the two types of observation?
Qualitative and Quantitative Observations.
What is a hypothesis?
A specific and testable prediction
What is the base SI unit for measuring length?
meter
583.2 cm = __________________ m
5.832 m
What step of the scientific method do you test your hypothesis?
Experiment
This type of observation is measureable.
Quantitative Observation
What is the scientific method used for?
To solve problems (or answer questions) in a scientific and organized way.
What is the base SI unit for measuring mass?
gram
6,894 kL= __________________ L
6,894,000 L
What step in the scientific method do you graph your data and/or make careful observations?
Analyze Data
This type of observation is describable.
Qualitative Observations
Dr. Cooper's experiment results did not support his original hypothesis. What should his next step be?
He needs to revise his hypothesis.
What is the base SI unit for measuring volume?
liter
0.0587 dag (dekagrams)= ____________ mg
587 mg
In which step of the scientific method do you present your experiment, observations and conclusions to others?
Report Results.
Qualitative Observation, Quantitative Observation, or Inference?
My science classmate is wearing goggles and has her hair tied back.
Qualitative Observation.
Dr. Peres' experiment results did support her original hypothesis. What should she do next and why?
She needs to repeat her experiment many times in order to be certain that her results are accurate.
What SI unit would a geologist use to measure the length of a small gemstone?
centimeter or millimeter
3 hm (hectometers) =_______ dm (decimeters)
3,000 dm
List all seven steps of the scientific method.
1.State the Question,
2. Gather Information,
3. Form a Hypothesis,
4. Perform an Experiment,
5. Analyze Results,
6. Draw Conclusions,
7. Report Results.
Qualitative Observation, Quantitative Observation, or Inference?
I think we are doing a lab in science today because my science classmate is wearing safety goggles and has her hair tied back.
Inference
How many variables can you include in a controlled experiment and why?
Only one variable because if you have more than one, then you won't know which variable is affecting your results.
What SI unit would a marine biologist use to measure the mass of a dolphin?
kilograms
87,586,321 kg = __________ cg (centigrams)
8,758,632,100,000 cg
