Scientific Method
Name the steps of the scientific method, in order.
What is....
1. Observation/Ask a question
2. Make a hypothesis or prediction
3. Experiment
4. Analyze Data
5. Conclusion
The three types of variables in an experiment.
What is a control, independent, and dependent variable?
Bias is when....
What is a person has an unfair judgment or opinion that influences the outcome of a procedure?
What is the ability to do work and cause change?
A force is defined as a ______ or a ______ that acts on an object. The two main types of force are ________ and ____________.
What is a push or pull; contact and non-contact?
Speed measures the _______ an object travels during a certain amount of time. Speed includes/excludes (choose one word) the direction of an object's motion.
What is distance; excludes?
What is raw data?
The organized procedure that tests a hypothesis or prediction.
What is an experiment?
The meaning of valid.
What is to be true, accurate, correct?
The Law of Conservation of energy states that.....
What is energy can only be transferred or transformed but not created or destroyed?
Velocity measures the ______ and ______ of an object.
What is speed and direction?
After an experiment has been completed, scientists make a conclusion. This conclusion allows scientists to either ______ or _______ their hypothesis or prediction.
What is accept or reject?
The variable that can be manipulated throughout the experiment. There can only be ______ of this variable in an experiment.
What is the independent variable and one?
Difference between a qualitative and quantitative observation.
What is qualitative observations focus on the characteristics or qualities of an object, quantitative observations focus on numerical values?
Three differences between scientific and societal law.
What is....
Scientific Law: Societal Law
Cannot be broken Can be broken
Is the same worldwide Changes often
Focus on nature Focus on behavior
Identify three types of contact force and three types of non-contact force.
What is applied, friction, normal are contact forces; gravitational, magnetic, and electrical force are non-contact forces?
Acceleration measures the rate of change in an object's ____________.
What is velocity?
An inference is a statement or question that is......
What is based on facts that have already been established?
This variable reacts to changes made to the independent variable.
What is the dependent variable?
To copy work that has been done by someone else is ________. When someone does something over and over again it is called __________.
What is replication and repetition?
The difference between transforming and transferring energy.
What is transforming energy is when energy changes from one form to another; transferring energy is moving energy from one place to another?
This type of force always results in a change in an object's speed, direction of motion, or both.
What is unbalanced force?
If an object's speed decreases, the object's _________ changes, which means the object is ___________.
What is velocity; accelerating?
What is the difference between a hypothesis and a prediction?
What is a hypothesis is a possible explanation for an occurrence but a prediction is just a statement about what may happen in the future?
Identify a difference between a controlled and independent variable. Identify a similarity between a controlled and independent variable.
What is a controlled variable must remain constant throughout an experiment but an independent variable must be manipulated throughout an experiment? What is both an independent and controlled variable can be controlled?
________ is the study of the natural world. An _________ is a question or investigation that allows us to explore our natural world.
What is science and inquiry?
Explain how a pendulum demonstrates the Law of Conservation of Energy.
What is as the pendulum swings back and forth its state of energy is always transforming from potential to kinetic energy and from kinetic to potential energy?
What is....
An object at rest/in motion will remain at rest/in motion until an outside force acts upon it.
Force = Mass x Acceleration
For every action, there is an equal but opposite reaction.
True or false:
An object that is travelling a constant speed in the same direction is accelerating.
What is false?
