Infectious Diseases
An Outbreak of Measles• 161 cases of measles in the U.S.
this year (January to August)• Last highest year was 2011, when
there were 222 cases• Nearly two-thirds of cases
happened in communities where many people don't vaccinate
• Nearly 40% of children under the age of five who get measles have to be hospitalized
Building on a Theme
Villain or Victim?
• How do you know that a disease is infectious?• Do you think cancer is an infectious disease?• Does being exposed to an infectious agent prove
that the agent has caused your disease?

What strategies do you use when reading?
Integrating Timed Readings
Let’s Start with Reading
http://www.marshalladulteducation.org/reading-skills-for-todays-adult
Questions: What is secondhand smoke? Why is it harmful?
What is close reading?
Close reading is . . . close sustained reading of grade-level appropriate complex texts to examine their meaning thoroughly and methodically, ultimately arriving at an understanding of the text as a whole.
Close reading is NOT…
• Skimming for answers• Surface processing• Reading and forgetting
Benefits
Close reading . . . • Strengthens student critical thinking skills.• Enhances student content understanding
through relevant applications.• Engages students with exciting new
perspectives.• Helps students develop ability to read
complex text independently.
Skills for Close Reading• “Tapping one’s prior knowledge
related to informational text structure.
• Topical and vocabulary knowledge.• Setting a purpose for reading.• Self-monitoring for meaning.• Determining what is important.• Synthesizing.” (p. 10)
Sunday Cummins PhD. Close Reading of Information Texts: Assessment Driven Instruction. Guilford Press, 2012.
A Model for Explicit Instruction ofComplex Text
• Provide context.• Read text aloud.• Students reread the text independently.• Guide discussion of the text after
“chunking.”• Give students constructed response writing
opportunity.
Life Science Application
Untangling the Roots of Cancer As you read the article, identify one or two
text-dependent questions that you would use in your Science classroom to ensure that students have completed a close reading.
Questions for Understanding• Text-dependent questions
– How is the recent evidence about cancer cell formation different from earlier evidence?
– What is the author’s prediction about the cause of cancer?
• Application questions– How does the author explain the “root” cause of cancer?
• Inquiry questions– Based on what you have learned from this reading, if you
were a cancer research scientist, what would you focus on next? Use evidence to explain why you would choose this research direction?
Effective readers use text structure to . . .
• Predict what is to be read
• Comprehend/understand text
• Observe the way the author has organized the text
• Look for key words and concepts
• Note the different headings and subheadings
• Notice and interpret graphics
Types of Text Structure
• Description
• Sequence and Order
• Compare and Contrast
• Cause and Effect
• Problem and Solution

A farmer purchased 30 acres of farmland. The farmer calculated that the average topsoil thickness on the farmland is about 20 centimeters.The farmer wants to maintain the thickness of the soil on this farmland by reducing erosion. The farmer plans to test the effectiveness of two different farming methods for reducing soil erosion.• Method 1: No-till (planting crops without plowing the soil)• Method 2: Winter cover crop (growing plants during the winter that are plowed
into the soil in spring)The farmer hypothesizes that using either method will reduce erosion compared to using traditional farming methods (plowing and no cover crop).Design a controlled experiment that the farmer can use to test this hypothesis. Include descriptions of data collection and how the farmer will determine whether his hypothesis is correct.Type your response in the box. This task may require approximately 10 minutes to complete.

Develop a Thesis/Hypothesis• Thesis Statement = The main idea or main point
of a written assignment.– Clearly identifies a topic– Contains an opinion or stance on the topic– Creates a roadmap for the writing– Answers the question: “What am I trying to prove?”– Usually located in the introduction
What’s Your Claim? ____________ position on _________________ is clearly supported by _______________ and _____________________.
_____________________ argues that ____________________________, which is supported by _____________________.
A key issue raised in both _________________________ and __________________ is that ______________________.
The long-standing position of ______________ is supported by __________ and _______________________.
In discussion of ______________________, one controversial issue has been ___________________. ________________ believes that _______________________ as supported by _________________________________.
What’s a Hypothesis?• Educated guess about how things work.• Prediction• Use If, then statements
– If ____ [I do this], then _____ [this will happen]• Focuses on one variable only.
Example: If skin cancer is related to ultraviolet light , then people with a high exposure to uv light will have a higher frequency of skin cancer.
What’s the Evidence?
What are the • key words • phrases• ideas • data that support the claim from the excerpt or the hypothesis?
Structure
Beginnin
g
• The introduction states the main idea or position. It begins with a topic sentence/thesis/hypothesis statement. The beginning restates the question and sets the stage to answer the prompt.
Middle
• Answer the question first.• Provide important information the author stated and meant. This is where
you go to the text(s) and provide examples/evidence and important details to support the answer.
• Sample phrases to introduce each text reference include: … stated; in the text …; for example . . .
• Include background information as required through the prompt.
Ending
• Write a closing that summarizes the position taken or restates the thesis statement in a different way.
Don’t Forget to Revise and Edit
• Structure and content
• Make changes to the substance of the writing from one draft to another
• Make corrections
• Ensure adherence to standard English conventions
• Use editing checklist

At 10:00 a.m. on Sunday, the Lin family set out on a car ride. For the first hour they traveled at an average speed of 40 miles per hour. In the second hour, traffic was heavy, so they only drove at 20 miles per hour. From 12 P.M. to 1 P.M., they stopped for lunch and did not drive at all. After lunch, it started to rain, so they decided to go home. They drove at 30 miles per hour to get home. Which of these graphs represents distance from the starting point over time? Total distance traveled over time? Speed over time? Hunger over time? How would you label the intervals on the y-axis of each graph?

Time Out for an Incredible Life Science Fact
How Many Skins Have You Had?In each year there are 365 days (except for leap year when there are 366 days). If we divide the number of days it takes to replace your skin cells (35) into the number of days in a year (365) you can see that the skin is replaced about 10 times.
365/35 = 10.428
Now if you replace your skin on average 10 times each year for 20 years you find that you have worn about 200 skins!
10 X 20 = 200
Now it's your turn. How many skins have you had? How many skins will you have had by the time you are 35 and 50 years old?

Forensic Science
The StoryThe chef at a prize-winning restaurant found his kitchen ransacked. He was furious, especially because he had been preparing for a big banquet. In fact, he had been working so frantically that he had spilled flour and baking soda all over the counter. As soon as the chef reported the crime, the police got right on the job. They have narrowed the search to two suspects. One suspect is the local caterer, a man who is competitive with the chef. He was known to be baking a cake for the banquet to try to steer some attention away from the chef. The second suspect is the woman who owns the banquet hall. Even though she hired the chef, she has never really liked him for reasons no one really knows.
The police have collected important evidence: samples of different white substances found throughout each suspect’s house. Police officers think that whoever committed this crime tracked the substance home. For this reason, police want to determine what the substances are and deduce whether they might have come from the chef’s kitchen. They have labeled the substance at the caterer’s house “substance 1” and the substance at the banquet hall owner’s house “substance 2.”
The Clues Are In!
Answer the following:
• Substance 1 is:
• Substance 2 is:
• Who ransacked the
chef’s kitchen?
Science MysteriesWhy do teachers use science mysteries?• To engage students who may often shun science• To teach basic science knowledge through exploration• To connect science to real life situations
How do teachers use science mysteries?• Teachers often have students read and discuss the first
episode. • Then students continue the story on their own until the
mystery is solved.• Classroom discussion summarizes what students have
learned.

Science Narrative ChainAlthough some of the places on the earth experience moderate temperature changes throughout the year, there are also areas where the temperatures are quite drastic. In some of the southern regions, one might experience a tropical rainforest or jungle-like atmosphere which is very hot and humid. Some parts of the earth are very cold all year long and are composed of glaciers or ice caps.
Sample Questions/Concepts
What are variables? – A review
Independent Variable Dependent Variable Control Variable
• What is tested by the scientist
• What is changed by the scientist
(What I change…)
• What is observed• What is measured• The effect caused by
the independent variable.
• The data
(What do I measure?)
• Things that could change but don’t
• Kept constant (the same) by scientists
• These allow for a fair test.
(What stays the same?)

Real Science! (or is it?)• One horsepower is the amount of energy it takes to drag a
horse 500 feet in one second.• You can listen to thunder after lightning and tell how close you
came to getting hit. If you don’t hear it, you got hit, so never mind.
• When people run around and around in circles, we say they are crazy. When planets do it we say they are orbiting.
• The body consists of three parts - the brainium, the borax and the abominable cavity. The brainium contains the brain, the borax contains the heart and lungs, and the abominable cavity contains the bowels, of which there are five - a, e, i, o and u.
