These are questions and vocabulary words that might be on the test!
Science
The investigation and exploration of natural events and of the new information we get from these investigations.
3 branches of science
Physical, Life, Earth
Physical science
It includes Physics and Chemistry and is the study of matter and energy. It is concerned with atoms, molecules, energy, motion, forces, and charges.
Life science
It includes Biology and Environmental Science and is the study of how living things interact with the environment.
Earth science
It includes Geography and Geology, and is the study of the water cycle, how weather happens, properties of rocks and minerals, fossils, oceans, and volcanoes.
8 main steps of making a Scientific Inquiry
Ask a question
Make a hypothesis
Predict your results
Design an Experiment
Collect data from the experiment
Analyze your results
Draw conclusions
Communicate results
Scientific Law
A rule that describes a repeatable pattern in nature.
Scientific Theory
An explanation of why or how something occurs.
Technology
The practical use of scientific knowledge, especially for commercial or industrial use.
Critical Thinking
Comparing the information given to prior knowledge or experience do decide wether you agree with it.
Prediction
A statement of what will happen next in a sequence of events.
Three ways we use scientific investigation results
Technology (the practical use of scientific knowledge especially for industrial of commercial use)
New Discoveries or events may be found as the result of scientific observations.
Answers to questions may be determined as the result of scientific observations.
Hypothesis
A possible explanation for an observation that can be tested by scientific investigations.
Observation
The results of using your senses to gather information and taking note of what occurs.
Inference
A logical explanation of an observation that is drawn from prior knowledge and experience.
Internationally accepted system of measurement
International System of Units (SI)
Explanation
An interpretation of observations.
Description
A spoken or written summary of observations.
Reference Point
The starting point you choose to describe the position of the object.
Position
An object’s distance in a certain direction from a reference point.
Motion
The process of changing position.
Vector Quantity
A measurement with an amount and a direction.
Displacement
The difference between the initial position and the final position of an object.
Speed
The measure of distance an object moves per unit of time.
Constant Speed
The rate of the change of position in which the same distance is traveled each second.
Instantaneous Speed
Speed at a specific instant in time.
Average Speed
The total distance traveled by the total time taken to travel that distance.
Velocity
The speed and the direction of a moving object.
Force
Push or pull on an object.
Contact force
A force that works by physically touching something.
Noncontact force
A force that does not touch something but still acts on it.
