Scientific Method
The first step in the Scientific Method.
Questions/Problem/Observation
One of the best ways to learn about matter.
Experiment
Maddy's ball is 15 newtons. Does this refer to weight or mass?
Weight
This determines if an object floats.
Density
To find out if Mr. B. bought Mrs. B. a real gold ring you would do this.
Measure it's density.
The last step in the scientific method.
Conclusion
Anything that takes up mass and has space.
I ate 30 grams of grapes at the Smith's house. Does this refer to weight or mass?
Mass
This substance floats on water but sinks in alcohol.
Oil
These types of observations can sometimes be unreliable.
Qualitative
This is the step of the scientific method where you make a guess.
Hypothesis
How much space matter takes up.
Liquid water becoming steam. Does this refer to physical property or chemical change?
Physical
Color, temperature, texture, density, mass, state.
Physical properties of matter
I kneed you.
What did the femur say to the patella?
True or False. All other areas of study, like English, use the scientific method.
False
The ability to float.
Buoyancy
Rust on a piece of iron. Does this refer to physical property or chemical change?
Chemical
Photosynthesis, rust, digestion, vinegar and water creating carbon dioxide, hydrogen and oxygen forming water.
Chemical change
Measurements that involve numerical data.
Quantitative
Changing only one thing at a time.
Controlling variables.
Mass divided by volume.
Justice lifted his 200 pound bike.
Weight
Mohs, Beaufort, Fujita, Saffir-Simpson
Scales used for measurement.
Mohs - hardness scale; Beaufort - wind scale; Fujita - tornado intensity; Saffir-Simpson - measures intensity of hurricanes.
Where Mrs. B was born.
Bronx, New York
