Steps of
Scientific Method
Scientific Method
When you make a guess based on data and background knowledge.
Prediction
A scale or balance measures this
Mass
The part of the experiment that you alter or CHANGE.
Independent Variable
You make qualitative observations using your five of these.
senses
Millimeters, meters or centimeters
Rules or stick
When you combine scientific FACTS to make a statement about what may happen in FUTURE situations
Inference
A graduated cylinder or beaker measures
Volume or capacity
The variable that changes
because of the change with the
independent variable. (It is the data collected).
Dependent Variable
Observations that can be counted or measured
Quantitative Observations
Grams of Kilograms
Scale or Balance
A summary statement based on results of an investigation.
Conclusion
This tool measures temperature
Thermometer
The part of the experiment that is kept the SAME
constant
Data that can be observed but NOT measured
Qualitative observations
Celcius
Thermometer
An educated guess or prediction based on what you already know written as an "if...then...." statement.
I would use this tool to measure length
Ruler or Stick
The type of liquid in our egg experiment is this type of variable
Independent variable
In our mentos and soda experiment we didn't measure the explosion with a yard stick so the results are what kind of data.
Qualitative
Liters or Milliliters
Graduated cylinder or beaker
You can organize the data from your experiment in one of these.
A graph
The egg turning rubbery like a water balloon is this type of variable in the experiment
Dependent Variable
A graph you make after the experiment shows what kind of data. Quantitative or Qualitative?
Quantitative.
In Science we don't measure length in inches because we use this system of measurement.
The metric system
