Identifying problems based on observations - Answer✔️✔️-Causal question—what am I

seeing, what hypothesis might I test to learn more information about what I am seeing?


Forming and testing hypotheses - Answer✔️✔️-Hypotheses make a prediction about

what will happen upon experimentation, but will not make inferences as to why

something is happening. I.e. As amount of physical exertion increases, heart rate will

increase.

Development of theories, models and laws - Answer✔️✔️-A theory is a thoroughly vetted

explanation for phenomena. It is not a name taken lightly, it is almost fact; no evidence

has arisen to disprove the theory. A model is a type of theory that attempts to explain

how something works. I.e. heliocentric model. A law is a theory that has been proven to

be fact, such as the laws of motion. It has been affirmed that no evidence will ever be

brought forward to disprove a law. Hypotheses become theories as they are tested and

supported over time. Theories become laws when it is clear no evidence will come

forward to disprove them.

Experimental design, including independent and dependent variables, controls, and

sources of error - Answer✔️✔️-The independent variable is the one and only thing about

an experimental setup that I am changing, in order to measure a dependent variable.

I.e. I change the amount of exercise, and heart rate changes as a result. Controls are

what stays the same in my experiment. I.e. how quickly I do jumping jacks, how many

jumping jacks I do, that the same person is doing the jumping jacks. Sources of error

include anything that may be changing data that is uncontrolled. I.e. food calorimetry

lab, not all heat is being captured efficiently by the water.

Process skills including observing, comparing, inferring, categorizing, generalizing, and

concluding - Answer✔️✔️-Observing; making observations and asking causal questions.

Comparing; evaluate two phenomena in light of each other

Inferring; using evidence to offer an explanation of why something is happening

Categorizing: using observations to organize information

Generalizing: knowing what can and cannot be included in a generalization

Concluding: drawing conclusions based on experimental evidence.

Nature of scientific knowledge: subject to change - Answer✔️✔️-As new evidence is

gathered, previous conclusions may change to fit the evidence. We can't know things

until we make hypotheses, and those hypotheses may be disproven.

Nature of scientific knowledge: consistent with evidence - Answer✔️✔️-We cannot call

something a scientific finding unless it is based on experimental evidence; anecdotal

evidence is insufficient.

Nature of scientific knowledge: based on reproducible evidence - Answer✔️✔️-Evidence

has to be reproducible in an experimental setting. A one-time phenomenon is not

enough to come to scientific conclusions. I.e. "I drank a soda and did well on my exam"

does not make drinking soda a tried and true way to do well on an exam; it needs to be

experimentally tested.

Nature of scientific knowledge: includes unifying concepts and processes (e.g.,

systems, models, constancy and change, equilibrium, form and function) - Answer✔️✔️-

Consistent with previous knowledge. Fits with other systems and models. Is able to be

disproven and/or modified.

Common units of measurement (metric and English) including unit conversion and

prefixes such as milli and kilo - Answer✔️✔️-Kilogram (kg) -- .5 kg in 1 pound

Second (s)

Kelvin (K)

Meter (m) - 0.3 m = 1 ft

Liter (L) - 0.9 L in 1 quart



Unit Prefixes from largest to smallest:

Giga

Mega

Kilo

Deci
