How can a substance be both a liquid and a solid?
- Do Now- Copy down today’s homework assignment in your planner. Get out your ISN and open to page 33.
- Initial Model/Explanation- In your cooperative table group, share your ideas about how a substance can be both a liquid and a solid. Come to a group consensus to draw a group model of the oobleck phenomenon on a piece of easel paper.
- Gallery Walk– Count off by the number of groups. All of the 1’s go to poster 1, 2’s go to poster 2, and so on. Each group will have a person who was from the group that made the model. Show your model and explain all the elements of the model. As a class, find similarities and differences and record these on the handout. If something is repeated several times, that is important!
- Identify Related Phenomena (Write-Pair-Share)– Think of other times when matter behaved in unexpected ways. Write down on ISN p.34 a brief description of other examples of matter a substances changing form. Try to come up with ones that make you wonder why/how it happened.
Answer questions in ISN p.34
How can a substance be both a liquid and a solid?
- Do Now– Copy down today’s homework assignment in your planner. Get out your science notebook and add to the Table of Contents- “Oobleck Model p.34” (Left Side). Head page 34 properly with “Oobleck model-12/12/17.”
- Initial Model/Explanation- Set up ISN p.34. Watch the phenomenon again carefully. Also check out this MythBusters and this experiment. How can the oobleck be both a liquid and a solid? On the white paper, draw your ideas of what you think is happening when the liquid becomes solid and/or the solid becomes liquid.
- Answer questions in ISN p.34
- Unit Cover page on ISN p.33 due tomorrow 12/13
- Write the title very large so that it is easy to read.
- Draw a minimum of 3 pictures that represents the unit.
- Color the entire page, corner to corner, using colored pencil or crayons- no white paper showing
How can so many different sounds be coming from the needle and the record when you spin it?
- Do Now– Copy down today’s homework assignment in your planner. Get out your ISN and add to the Table of Contents- “Model p.30” (Left Side); Head page 30 properly with “Model- 12/5/17.”
- Complete Investigations 1-3- Let’s look at the record and needle again to see if its vibrations are changing as it produces different sounds…We’ll look again at the Michael Jackson video of the closeup of the needle on the record. This time, look to see differences in the frequency or amplitude of the vibrations of the needle as it produces sound. Answer questions Q3-Q6 in handout. Look through the procedure for Investigation 2. Complete it with a partner. When you are done with Investigation 2, send one partner to the demonstration desk to get a copy of the photograph of the surface of the record. You will be able to write, label, & draw on this photograph so be prepared so share your findings.
- Model– How can so many different sounds be coming from the needle and the record when you spin it?
STUDY for the Sound Source Quiz tomorrow 12/6– ISN pages 15-31
What does the record look like up close?
- Do Now– Copy down today’s homework assignment in your planner. Get out your ISN and open to page 20. Read your conclusion on page 20 to your group.
- Model/Consensus Circle– Add what we observed about the surface of the record and the interaction of the needle and how it was related to sound to the class model.
- Next Steps– How might what we figured out about the record playing sound be related to other sound source experiences? Set up ISN p.20 with the following questions: Do you think other objects that produce music also move back and forth when they produce sound? (Write-Pair-Share) How might we go about investigating this question further? (Write-Pair-Share)
- Complete Questions on ISN p.20
- ISN’s are due next week! 🙂
How can we hear so many different sounds from across the room when we spin the record?
- Do Now- Copy down today’s homework assignment in your planner. Get out your ISN and open to page 17. Read your observations of the sound device on page 17.
- Initial Model/Explanation- How does the sound come from the needle and the record? How did all of those patterns that we observe happen? How can we hear all these different sounds from across a room? On the handout, draw your ideas of what you think is happening where the needle touches the record, and what is happening in the air between the sound source and your ear that would really help show and explain, how is it possible we can hear all these different sounds coming from the device?
- Consensus Circle– Review discussion & circle norms. Bring your models to the circle. Show your model and explain all the elements of the model. As a class, find similarities and differences and record these. If something is repeated several times, that is important!
ISN p.16- Write 2 questions you have related to sound and how we hear different noises.
