What are the basic steps of scientific inquiry
- Ask a question
- Do background research
- Make a hypothesis
- Conduct experiments/test/observations,
- Conclude
If the hypothesis is correct, share it, if it isn’t right start at step 2 again.
What is a hypothesis
It is an educated guess
If your observations do not support your hypothesis, what should you do?
You should make a new hypothesis, and start the process over from that step.
Compare and contrast a theory and a law
A theory explains why something works under a situation, while a law explains what happens under a situation.
What are models, and why are they used in science
Models are something used to represent something. They are used in science to represent something that is too big, small, or expensive.
How is evidence used in scientific investigation.
It is used to prove the hypothesis or not prove it.
Give an example of a physical model, a computer model, and a mathematical model
Physical model- Globe, map, figurine
Computer model- A virtual reality
Mathematical model- An equation
What is a procedure
A step-by-step list of how to carry out and experiment
What is an independent variable
It is the variable that is changed on purpose in an experiment by the scientist
What is a dependent variable
It is a variable that depends on the independent variable. The observed outcome (result) of an experiment
What is a constant
Factors in an experiment that remain the same
What is a control
A trail where all the variables are held constant.
What is the difference between precision and accuracy
Precision is how consistent and exact a measurement is, while accuracy is how close to the actual or true value a measurement isy
What does a hypothesis tell you in a lab report
What predictions are you testing
What does a procedure tell you in a lab report
The list of steps necessary to carry out the experiment
