Science and Engineering Practices Flashcards
Scientific Method
The way scientist study learn about the world.
Observation
Using your five senses to gather information about something.
Qualitative Observation.
Using your senses to discribe characteristics of an object-color, texture, taste,.
Quantitative Observation.
Using number or measurements to describe something.
Inference
n explanation of an observation based on prior knowledge.
Hypothesis
A prediction based on prior knowledge. Always written in an if then statement.
Claim
Is the answer to the question you are trying to answer
Variable
Any factor that can be manipulated, controlled for , or measured an experiment
Control Variable
What must stay that same in the experiment.
Manipulated/independent Variable
The thing that are testing or changing in an experiment and its is graphed on the X-axis.
Dependent/Responding Variable
What you are measuring
C-E-R
Claim, Evidence, Reasoning
Evedence
Scientific data that supports your claim.
Reasonings
The how or why the evidence supports our claim: science rule.
Conclusion
You state whether your prediction was confirmed or no and try to explain your results.
Mineral
A substance that is formed naturally, Is inorganic ,has definite chemical composition an had a crystal structure
Streak
The color of a mineral’s powder when it is rubbed against a porcelain plate.
Luster
The way the surface of a mineral reflects light.
Inorganic
not derived from living matter.
Crystal
A solid formation that follows a pattern
Hardness
The ability of a mineral to scratch or be scratched by another mineral
cleavage
The tendency of crystals and minerals to break along definite planes resulting in smooth surfaces.
Fracture
The appearance of a freshly broken surface on a mineral that has a rough or irregular surface
Mohs hardness scale
A hardness scale used to classify minerals.
