Text for Case Study 3
Based on the text, what are some things you think we will be talking about in the Socratic Dialogue tomorrow? You can write questions you want to ask, ideas that might come up, or vocabulary you should know.

SOCRATIC DIALOGUE PREP
SOCRATIC DIALOGUE PREP
- Which ball bounced the highest?
- Which ball bounced the lowest?
- Why do you think they bounce differently?
- How do you think the materials the ball is made form affect its bounce height?
- What are some steps a materials scientist might take to change how high a ball bounces?
Vocab Group: watch the video below and work together to create at least 2 participations per person that you can use in tomorrow's dialogue. Consider questions that relate to the vocabulary words you have defined, or questions about parts of the text that you need clarification on.

Content Group: compare your summaries and make sure you are clear on the gist of every part of the text. Work together to identify parts of the text that you could use in tomorrow's dialogue as evidence to explore the Big Idea. Make sure everyone is ready with at least 2 pieces of evidence from the text and/or questions to use in the dialogue.

Connections Group: compare your connections and write down any that enhance your understanding or ability to explain. Look at the Big Idea and decide how to best steer the class in the discussion. Divide the responsibility for the Big Idea and let Finn know who will be going for the 4.

Some chemical reactions produce polymers - large molecules that are made up of many smaller molecules bonded together in a repeating chainlike pattern. This structure affects the properties of the substance.
Some chemical reactions produce polymers - large molecules that are made up of many smaller molecules bonded together in a repeating chainlike pattern. This structure affects the properties of the substance.
Why is Teflon a synthetic material? [It is made by humans, but it is made up of naturally occurring substances - the elements carbon and fluorine.]
Why is Teflon useful? [It is heat resistant and has a low surface friction, which means that most other substances won't stick to it.]
Given those properties, why is Teflon commonly found in items such as pots and pans? [Teflon is a non-stick material that coats pots and pans so that food doesn't stick to the pan.]
How does the structure of polymers relate to their properties? [Polymers are so large that they become entangled with each other. The polymer molecules can slide past one another, but they are still connected together. Polymers tend to be strong and resistant to breaking because of this structure. In contrast, small molecules like water do not tend to get tangled with each other because each water molecule is separate from the others.]
How does the example in the lab manual about steel chains and magnets connect to the visual's diagram of how bouncy balls form? [Each steel chain is made up of hundreds of individual links, but the chains themselves are not connected to any other chain, similar to how polymers are made up of hundreds (and sometimes thousands) of smaller molecules. When you mix sodium borate with water and then add the solution to the glue, it has the same effect as adding magnets to steel chains. The sodium borate molecules react with the molecules of polyvinyl acetate molecule chains, creating cross-linked (bonded) chains.]
LAB WRITE-UP REVIEW
LAB WRITE-UP REVIEW
- Make sure you are using the headers as we agreed upon (see example lab write-up)
- Make sure you are writing a title and Table of Contents entry for the lab
- Make sure all lists are bulleted or numbered (research, materials, procedure)
- Make sure experiment summary includes IV, DV, constants, and controls (some experiments don't have controls)
- Make sure diagram is at least half a page, includes all materials, and is labelled
- Make sure data table and graph are complete and axes are labelled
- Make sure conclusion follows format (restate hypothesis, make a claim, support with specific evidence from experiment, finish with "We conclude that ... ")
MAKE SURE YOUR LAB WRITE-UP IS NEAT, THE STEPS ARE IN ORDER, AND YOU DON'T WRITE ON THE BACK OF PAGES!
