Do Now: Take a marker and as a group, share your ideas and write down facts about sound. What do you know?
Take your marker and as a group, move to the next whiteboard. Read through the sound facts written down and add any new ones you think of. Repeat. Return to your whiteboard and read the facts. Circle or star the facts that are important for understanding how to build an effective noise barrier. Let's list these ideas for the class on this Google Doc NEXT: Share your Design Noise reduction results: Google Doc
What are the two ways sound can be blocked from coming through our door? We are using materials to reflect and absorb sound. We know that sound is a wave of energy that moves the particles of matter as a vibration. Let's draw models to try to explain how sound waves, hitting some type of material might be reflected and how it might be absorbed. We will discuss what happens to the matter and what happens to the energy. THE KEY is that the sound wave get's reduced or changed into some other kind of energy. Go to Google Classroom for Mar 30 to open your assignment called: Scientific justification for Door Noise design choices. Use the scientific principles of sound energy reflection and absorption to analyze how you think each of your design features helps block sound. Develop our testing box and protocol.
Finish building our first prototypes. Check for feedback and Missing Work: See March 3 and March 9 on Classroom to find your assignments for writing up the criteria and constraints (Mar 9) and doing the background research (Mar 3) for why stopping the noise can help our learning. Do Now
Meet with your group/partner from yesterday. Go over the plans you made, and determine a goal for the class period. This could be gathering materials (whether physically or online shopping); beginning creation on your prototype; developing blueprints; working on your reasoning behind the materials you've chosen, etc. Do Next | Go Around We will share out goals for the class period that I will capture and put on the board. Studio Time Take this time to work towards the goal you set. Begin by dividing up the tasks among your group/partner, and then hold each other accountable for their portion of the work. While we do this, the noise level should be like a quiet hum of backround noise. Ticket Out On your way out, please rate your habits of work on a scale from 0-4, and explain why you gave yourself that rating. Do Now:
Find your elevator pitch from yesterday. During the next 5 minutes, revise any statements that you feel could be clearer, and read through your speech for practice. Do Next: Popcorn If you are interested in sharing your elevator pitch, please “pop” out of your seat and stand up to face the class before beginning your pitch. Today’s Objective: By the end of class today, each student meet their partner for the project, decide on a design that they want to build over the course of this week, and gather materials to do so. Grouping In a few minutes, we will be assigning random partners to you. Each partner group will be responsible for completing at least one (1) prototype design. This design might be a combination of each of your individual designs, you might choose one person’s design to run with, or you might come up with something entirely new. Create Groups We will use the spin wheel that Chris has to assign your partners, then assign you a place in the room to work. If you have a legitimate issue with your partner, please pull Chris or I to the side to talk about it. Collaborate Once you have made it to the table where you and your partner will be working, pull out your Elevator pitch. We will assign a group member to go first, and then each person will have a minute for their speech, followed by a minute for clarifying questions from their partner. Then, we will switch roles. Now that you have a better understanding of your partner’s thinking and ideas, it is time to decide on a finalized design that you want to prototype this week. Once you have decided on that design, create a drawing of it in your science notebook that labels all of the parts and their purposes, as well as any important measurements. After you have created this design, the next step is to figure out what your prototype will look like, as we aren’t building a full size model. If you finish all of this, create a new bill of materials for your revised design, ad then use that Bill of Materials to obtain the products you ned to Ticket Out As you leave, please identify what your next steps are. What is the first thing you need to do during class tomorrow? Do Now:
Find your design from last week. During the next 2 minutes, identify one of the following to share:
Each person will share their response to the do now. We want to do this quick, so state your thought and then we will keep moving around the room. Today’s Objective: By the end of class today, each student will create a bill of materials for their soundproofing design, meet their partner for the project, and decide on a design that they want to build over the course of this week. Bill of Materials A bill of materials is a structured list that contains all of the materials, components, parts, etc. needed to create/manufacture a product. This includes obvious things, like cardboard or egg cartons, but also smaller details, like hot glue, or a utility knife. Your bill of materials should contain all of the elements you will need to create your design as it stands right now. I have uploaded a template for you to use on the Google Classroom. You will have the next 10 minutes to review your design and enter in the materials, quantities, and tools you would need to construct your design. If you have questions, please raise a hand so we can assist you. Mix & Mingle We will spend the next 5 minutes doing a mix and mingle. Please stand up and start moving around the room. If there is an empty space, fill it. Keep moving around until you are told to “Mingle” and then find a person near to you. You will each have 30 seconds to share the following:
Debrief What were some of the things you heard during the mix & mingle? This could be unique ways to use materials, unique materials themselves, interesting ideas for a design, etc. Grouping In a few minutes, we will be assigning random partners to you. Each partner group will be responsible for completing at least (1) prototype design. This design might be a combination of each of your individual designs, you might choose one person’s design to run with, or you might come up with something entirely new. Take the next 5 minutes to develop an Elevator Pitch for your design. This should be a speech that is no more than a minute long, that features the important elements of your design, and identifies why someone should trust why this design will work. You might find it useful to write this speech down. Create Groups We will use the spin wheel that Chris has to assign your partners, then assign you a place in the room to work. Collaborate Once you have made it to the table where you and your partner will be working, pull out your Elevator pitch. We will assign a group member to go first, and then each person will have a minute for their speech, followed by a minute for clarifying questions from their partner. Then, we will switch roles. Now that you have a better understanding of your partner’s thinking and ideas, it is time to decide on a finalized design that you want to prototype this week. Once you have decided on that design, create a drawing of it that labels all of the parts and their purposes, as well as any important measurements. If you finish all of this, create a new bill of materials for your revised design. Ticket Out As you leave, please identify what your next steps are. What is the first thing you need to do during class tomorrow? Do Now: Log into this Kahoot for some sound wave review. You will need to be able to use the principles (science facts) about sound waves when you discuss how your engineering project works.
Absorption of sound: Draw a model of what is happening to the energy and the matter on a white board. Handout of the Science Principles of Sound -
Get out your Draft design from yesterday. Use the principles of sound and your research on absorption to explain the parts of your design and how they will stop sound from coming through. Speed Dating: Be ready to explain your design to other students.
Grouping up and collaborating to revise your design in preparation for building your prototype on Monday LIST OF DESIRED MATERIALS Science Skill Do Now: Grab a yellow sheet at the door. See if you can solve this problem to find the frequency of a sound wave.
LESSON
Work as a group. Discuss why you made the choices you did in your ranking. What scientific facts have we learned that helped you come to your ranking? Count off...the 1's stay at your table, the rest will spread out to a new table. The 1's who stayed behind will explain their ranking and reasoning. The other students should offer their ideas, agree, disagree and what is the scientific reason why. Repeat one more time before going back to your own table. Paper Handout - Now that you have heard a lot of educated opinions about the materials, brainstorm a very rough draft idea (just an idea) for the materials you might use and how you might use them for your first design. Even if a material might be hard to come by, you can add it to your first design if it is not too crazy. Titanium would be a "No!" You can make substitutes later when you know for sure what materials we can actually get. If we have time... Move to a different table that has nobody from your original table - 3-4 per table. Take turns presenting your draft engineering design. Jot down notes from feedback you get on the back of your sheet. Record any new ideas you got and how you might change your design. Ticket out: Turn in your draft design ideas with your name on it. What part of the design do you like the most? Do Now:
