assignment – tomorrow is final turn in

Scientific Methods – True or False

• There are many methods scientists use to solve problems

• There is one set of 5 steps called The Scientific Method that all scientists use

• Scientific methods aren’t used by non-scientists

• A theory is just an educated guess

Scientific Methods – True or False

• There are many methods scientists use to solve problems TRUE

• There is one set of 5 steps called The Scientific Method that all scientists use FALSE

• Scientific methods aren’t used by non-scientists FALSE

• A theory is just an educated guess FALSE

Scientific Methods

• Scientists use many different methods, depending on the question

• They can do descriptive, comparative, or experimental investigations

• They can make models, either real or computer-based

• They can analyze data, recognize patterns, and make predictions

Scientific Methods

• What is sometimes taught as “The Scientific Method” is just a logical problem solving process

• It can have 5 – 7 steps depending on the source

• Real people use it all the time – they just don’t realize it!

• No one single person invented it, but…

Testable Questions

A question that can be answered through observation, measurement, testing, or analysis

Testable: How does water purity affect surface tension? Which material is the best insulator? Non-testable: Which tastes better, Coke or Pepsi? Which are cuter, puppies or kittens?
