Nature of Science
OBJECTIVES




Share thoughts, resources, and experiences on this
issue
Create a shared language for terms so that we can
apply and reinforce definitions in future contentbased activities
Determine how to address student misconceptions
regarding the nature of science
Discuss whether and how to implement the Nature
of Science within workshops
OUTLINE

5 minutes: Initial feedback from all: is this something that you
integrate in your lessons already? Is it a stand-alone or
introduction at the beginning of the year? Is it addressed in the
curriculum?

20 minutes: Review the Probes on “Science,” “Hypothesis,” and
“Theory” together, to help build shared vocabulary and unify
various understandings of the Nature of Science

10 minutes: Discuss common student misconceptions

5 minutes: Discuss language we use, terms that reinforce
misconceptions

20 minutes: Group Discussion and Brainstorming

PROBES: WHAT IS A HYPOTHESIS?
_____ A. A statement that can be tested
_____ B. A guess made before any observations are conducted
_____ C. A question asked at the beginning of an investigation
_____ D. A statement that may lead to a prediction
_____ E. Used to prove whether something is true
_____ F. Eventually becomes a theory, then a law
_____ G. May guide an investigation
_____ H. Used to decide what data to pay attention to and seek
_____ I. Can be developed using imagination and creativity
_____ J. Must be in the form of “if…then…”

_____ E. A theory never changes.
_____ F. Theories are inferred explanations, strongly
supported by evidence.
_____ G. A scientific law has been proven and a theory
has not.
_____ H. Theories are used to make predictions.

SCIENCE IS
Four students were having a discussion about how scientists do their work.
This is what they said:
 Antoine: “I think scientists just try out different things until something
works.”
 Tamara: “I think there is a definite set of steps all scientists follow called
the scientific method.”
 Marcos: “I think scientists use different methods depending on their
question.”
 Avery: “I think scientists use different methods but they all involve doing
experiments.”
