Science
A way of learning about the natural world
Science
The first step in an experiment
Recognizing the problem
A prediction about a problem that can be tested to find out if it is true or not.
a hypothesis
any representation of an object or an event used as a tool for understanding the natural world
a model
The fourth step of the scientific method
experiment
Rules that can not be changed
ex.) Newton's Law of Universal Gravitation
Scientific laws
The third step of the scientific method
Give an example.
-Hypothesis
-I think....
the variables that are kept the same throughout the entire experiment
constants
The branch of science that is the study of matter and energy
Physical science
Models that describe how someone thinks about something in the natural world.
Idea Models
an attempt to explain a pattern observed repeatedly in the natural world
Scientific theory
The independent variable in the Water Bottle Flip experiment
Amount of water in the bottle
Information gathered from an experiment through observations in the form of tables, graphs, or drawings.
data
A collection of structures, cycles, and processes that relate to and interact with each other.
a system
The last step of the scientific method
drawing conclusions
The three types of models
Physical Models, Computer Models, and Idea Models
Two of the constants in the Water Bottle Flip experiment
-size and shape of the bottle
-person flipping the bottle
-surface the bottle was flipped on
-the technique
The factors that can be changed in an experiment.
variables
The practical use of science to help people.
Technology
Give an example of a system.
answers will vary
The three branches of science
Life Science, Earth Science, and Physical Science
The dependent variable in the Napping Cat Experiment
If the cat sleeps after eating the tuna and how long before he falls asleep.
changes as a result of the change in the independent variable
dependent variable
To draw a conclusion based on something you observe.
to infer
Name two things a scientist should wear in a lab to be safe.
goggles, an apron, plastic gloves
