Lets Review - Developing a Scientific
Model and Engaging in Argument
The model is a simplified representation of a system or phenomenon
Central features are made explicit and visible (including those that are not observable with eyes)
Appropriate labels are included to clarify the model’s components
The model allows opportunities to explain what we think is happening
Discussion of models or parts of the model allows for engagement in argument with evidence.

Model Development #1
Candle Burning Experiment
Draw and label observations at the beginning, during, and after a few minutes.
Generate a question about what you observed.
Why does the water rise in the jar ________?
Generate your preliminary answer to your question.
I think _________ because _________
Share ideas with your table group. Do you all have the same ideas? Discuss.
Be ready to debrief with whole group.

Model Development #2
Burning Candle Investigation
What happens when you place a jar over a burning candle in 100 ml of water? Why? Consider Variables that can be explored.
Write a prediction in your space:
I predict ___ because___.

Model Development #2
Conduct the investigation, considering all variables
Observe what happens/ Data Collection
Draw and record your observations using the “before, during
and after” time frame

Sense Making: Group Talk
I think___, because___ .
I claim___. My evidence is ___ .
I think the cause of ______ is _____ .

Develop a Scientific Model
Based on your conversations and
experiments develop a scientific model
that explains the rise of the water.
Include:
Observable and unobservable features.
Making the invisible visible using symbols to
represent the invisible.
Connection to concepts .
Add new understandings that explain the
answer to the question.

19
Claim and Evidence
Let’s formalize your initial explanation by
writing a claim and supporting your claim with
evidence.
I think___, because___ .
or
I claim___. My evidence is ___ .
Alvord USD PL NGSS Oct. 2015
20
Further Investigations
How confident are you in your claim?
Strengthen your claim by collecting research.

Inquiry into the Text Reading the text with a purpose:
What information in the text helps you explain
the phenomenon in the investigation?
* = Mark information that helps to answer the
question & why
! = Note interesting ideas & why
? = Write questions you have
Circle= unfamiliar words
Alvord USD PL NGSS Oct. 2015
22
Sharing Ideas from the Text
Make silent eye contact with someone across
the room who you haven’t shared with today.
Take your article and share with them
questions you have and information in the text
that helps explain the phenomenon.
Alvord USD PL NGSS Oct. 2015
23
Making a Group Model
1. In your table group, share your individual models.
2. Discuss what the group model might look like for the phenomenon by comparing and contrasting each other ideas.
3. Together come to a consensus on what your group model should include/exclude.
4. Develop your consensus model on chart paper.
5. Write a preliminary consensus explanation describing the phenomenon using evidence from your experiments and reasoning from your research

24
Make Your Model Public
1. Exchange models with another group
2. Discuss the other group model at your table
3. Give feedback to the other group using sticky
notes feedback protocol
4. Return the other group model and review the
feedback you received on your group model.
5. What would you change/add?
Alvord USD PL NGSS Oct. 2015
25
Feedback Protocol
Yellow – ask for clarification of ideas
• What do you mean _____ ?
• Can you elaborate on how the ______ supports the model?
• I respectfully disagree with ___ because___.
Blue – build on and add ideas
I want to add to your idea_____.
Orange – agree and praise ideas
• I agree with your thinking on _________.

Revise your Group Model
Modify your model based on:
Feedback from other group
Discussion
Reading
Revise your explanation based on the
modification(s) to your model
Alvord USD PL NGSS Oct. 2015
27
Arguing for your Model
Share your revised model and explanation with
your collaborating group.
Address the modifications and the response to
feedback.
We added _________ because_______.
We changed ________ because______.
We used to think _________ now we think____.
We agree/disagree with ___________ because ________.

Debrief #1 Progression of the Disciplinary Core Idea
Read the PS3 (energy) progression.
Discuss how the idea of thermal energy
transfer is developed throughout the grade
levels.

Debrief #2 Analysis of the Practices
1. At your table, each person chooses one NGSS
practice (models, argumentation, explanation).
2. Look at the progression for your practice and
write on sticky notes when and how during the
investigation you experienced components of the
practices.
3. Share with the whole group.

Characteristics of Scientific Models
1. Represents a system or a phenomenon
2. Context rich and specific
3. Pictorial (drawings and pictures) and
written (text, equations, etc.)
4. Observable and unobservable features
5. Revisable over time
6. Public

Component #1
•What causes the seasons?
•Why do planets and moons
maintain the orbits they have?
•Why are solar eclipses so rare?
Represents a phenomenon
for which we have questions Does not represent a thing

Classroom Strategies for Modeling
and Engaging in Argumentation
1. Starting points: small group and individual work
2. Before-During-After drawings
3. Whole class consensus model
4. Peer feedback via sticky notes
5. Language scaffolds with sentence frames
6. Content checklists

Fostering Argumentation in
the Science Classroom
Establish classroom norms for productive interactions
between students
Create a culture of accountable talk
Make sure all students have equitable access to the conversation
Create a need for students to argue
Engage students in phenomenon that might elicit multiple responses
Make sure students consider alternative ideas
Encourage students to use criteria to evaluate the
processes, context and explanations of science
Encourage students to make their thinking visible
Make sure students have access to relevant data or evidence
