Scientific Methods
There is only one scientific method, and all scientists follow it in exactly the same way. True or False?
What is False?
Science is a way of learning more about the ________________________.
What is the natural world?
Qualitative or Quantitative: 12g
What is Quantitative
WHAT happens
What is a law?
What does CER stand for
claim, evidence, reasoning
A prediction about the answer you expect to get from an experiment is called this.
What is a hypothesis?
What is 100%?
Qualitative or Quantitative: round, small, shiny
What is qualitative
HOW or WHY something happens
What is a theory
What is it called when you test your hypothesis by changing variables and keeping controls to record data?
What is an experiment?
Which axis does the independent variable go on
What is x-axis
What is it called when another scientists does your or another scientists experiment
What is replication
These are used when you are making observations.
What are your senses?
A theory and law should be based on this.
What is evidence?
The information you gather during an experiment that might be shown in a chart, graph, or table would be this.
What are data?
The answer that you get at the end of your experiment based on the data you collected would be this.
What is a conclusion?
What is it called when you do the same experiment over and over again; multiple trials
What is repetition
What you measure in an experiment: how far the car traveled
What is a dependent variable
When something on Earth is heavier than the air, it falls to the Earth
What is Law
What is a variable?
An experiment to determine the average bounce height of a tennis ball drops it from a height of 5 feet and measures the rebound. The result from a single drop is 3.5 feet. The experimenter concludes this is the average bounce height. What is the error?
What is not enough trials?
When something is too big, too complex, or too expensive to use for experimentation, scientists often use these.
What are models?
What is the variable you change in an experiment: height of ramp
What is an independent variable?
All living things are made of cells, cells are the basic unit of all life, all cells come from preexisting cells
What is Theory
The group you leave alone or treat normally in an experiment so that you can see if the tested variables really make a difference would be this.
What is a control group?
