REFLECTIONS
The pages that follow contain questions that should
be answered AFTER reading the chapter lesson AND
completing your notes.
 These pages contain multiple copies of the same
set of questions and are typically cut apart by your
teacher and handed out in class for you to glue
into your notebook (Always place them on the
top, center of the page.)
 Reflections will always be completed on EVEN
numbered pages which are on the right hand side
of your notebook. Be sure to refer to the
Notebook tab on this web page, or your table of
contents, to find out where each page gets glued.

As a student completing make up work on your
own, please remember, you only need to glue ONE
COPY of the questions for each chapter section
into your notebook. (Do NOT glue the entire
sheet.) THEN you must ANSWER the questions!
 All work will be graded and you must justify your
answers with evidence from your notes or text
and use science vocabulary terms correctly in your
answers.

2.2 Reflections Scientists and Society
Describe one example of a scientist who caused controversy (advanced must describe two
examples). Be sure to include the following information in your answer(s):
1) Name of the scientist.
2) What he/she discovered or what idea they introduced to society?
3) Why did his/her idea cause controversy (why did society disagree or disbelieve)?
4) Did society change its opinion later on? Explain.
Answers must be written in 5-7 sentences in paragraph, NOT as a list of answers #1-4

Reflections: 2.3 How Science Changes
1. Compare and contrast a scientific law and a theory.
2. Show how our concept/understanding of the solar system changed over time by
summarizing the information below as key ideas placed on the timeline.
Facts to summarize:
388 B.C. the philosopher Plato hypothesized that the Earth was at the center of the Solar system and
the planets orbit in circles around the Earth
150 A.D. the philosopher Ptolemy supports Plato’s beliefs of an Earth-centered solar system abd
circular orbits
1543 Copernicus states his hypothesis of a sun-centered solar system and planetary circular orbits.
1609 Kepler confirms sun-centered solar system with elliptical orbits.
1610 Galileo uses a telescope to gather data on the solar system and confirms the heliocentric model
of the solar system with elliptical orbits and develops the Laws of Motion

Reflections: 2.4 Models as Tools in Science
A Model of
the Respiratory System
AFTER completing the class activity, 1.) draw and label a picture of the respiratory system
model, 2.) answer the following questions underneath this “cover page”.
1. Explain why scientists use models?
2. Explain how a model of a system can be used / useful?
3. When the diaphragm contracts, the downward pull of the muscle changes the air
pressure and pulls air/oxygen into the lungs, when the diaphragm relaxes, it pushes
against the lungs, forcing the air/CO2 out of the lungs. When you have the hiccups, the
diaphragm is having a muscle spasm and your breathing changes as a result.
a. Given the information above (considering only this system and not how other
systems interact with it) go back to your picture and label & describe the
process, input, output, and feedback in the system.
