This lesson was created by Ken Yoshikawa and implemented into our 8th grade Distinguished Students program, during the Fall Semester. Carmenita Distinguished Scholars Program 8th Grade Science OVERVIEW: 8th grade Science DS students will research and produce within the next few years AUDIOCASTS covering all 8th grade science topics. When sufficient number of AUDIOCASTS are produced, all students will be able to access DS AUDIOCASTS at any time in various forms: • AUDIOCAST downloads from the class website • Download AUDIOCASTS onto personal MP3 players or Flash Drives from classroom computers. • Purchase low cost CD’s containing ALL AUDIOCASTS covering the key 8th grade science topics. ASSIGNMENT: Research and produce an “AUDIOCAST” on a selected topic. GOAL: To enhance student understanding of a given topic by providing an additional opportunity and method of learning for peers. DUE DATE: Final AUDIOCAST due on January 7th, 2009 (Wednesday) PODCAST: Duration: 5 minutes minimum to 8 minutes maximum in length Format: .WMA file using Windows 98/ME/2000/XP and .WAV file using Windows ME/2000/XP/Vista Software: Windows Media Audio (look in “accessories”) Auido Editing: A free software is available from Audacity and gives you improved sound quality and the ability to edit your AUDIOCAST. (download “Audacity 1.2.6” ) http://audacity.sourceforge.net Works with Windows 98 / ME / 2000 / XP / Vista PROCESS & SCHEDULE: Due on or before .1. Selection of AUDIOCAST topic from a list 12-5-08 provided by your instructor. .2. Research of selected topic and to complete 12-17-08 a typed draft of your AUDIOCAST for instructor review. .3. Finalization / Approval of draft script 12-19-08 must be completed before Xmas break! .4. Completed AUDIOCAST may be submitted 1-7-09 on a flash drive or by CD. If a flash drive is submitted, it will be returned in 24 hrs. TOPICS TO BE DISCUSSED (minimum): .1. Overview of AUDIOCAST topic (what you will focus your discussion upon.) .2. State you’re “Learning Goal” for the student that will listen to your AUDIOCAST. .3. Teach: .a. In your own words, describe what it is. .b. Why is it important to know and give examples of how it is applied / used in your daily lives. .c. Instruct in detail how to solve problems in a step step manner. .d. What are the “key” things to know .e. Provide problems for your listener to solve. (Instruct the listener to turn off the AUDIOCAST while they solve your problem(s) ) .f. Explain solutions to each problem .g. Provide a summary of what was covered and what the student should have learned. .h. Provide sources for the student to go to for additional practice and information. .4. Close / Salutations. 8th GRADE DS TOPICS AVAILABLE FOR DECEMBER 2008 by Mrs. King: (note: only one DS Student per topic. Once the topic is chosen, it is not available for other DS students.) 1. Buoyant force • Archimedes Principle • How to calculate the buoyant force of any object 2. How to predict if an object will sink or float based upon two (2) possible methods: • Density • or Buoyant Force 3. Newton’s 1st Law of Motion • Inertia • Momentum 4. Newton’s 2nd Law of Motion • F = ma 5. Newton’s 3rd Law of Motion • For every action there is an equal but opposite reaction 6. Kinetic Energy • KE = mv2 2 7. Potential Energy • PE = wh 8. Acceleration: How to use: • a = v1-v2 t 9. Laws of Conservation of: • ME = KE + PE • Energy • Matter 10. “Buoyant Force Take Home Lab Exam” • What will the student be required to demonstrate? • Based upon your experiences, what should the new student know and what should he/she do to prepare? • What are the key points? • What are your recommendations? • What are the strategies? 11. “Density Lab Final Exam” • What will the student be required to demonstrate? • Based upon your experiences, what should the new student know and what should he/she do to prepare? • What are the key points? • What are your recommendations? • What are the strategies? 12. Density • Steps necessary to find the Density of any object or fluid: o Object • Regularly shaped • Irregularly shaped o Fluid It is recommended that you choose 3 topics and rank them by preference. Once you have made the selections of your DS Topics, be sure to confirm with Mrs. King that your selected topic is still available and that it has been removed from the list of available topics. Have fun as you learn!

 

Objective(s)  1. Forces 2. Unbalanced forces cause changes in velocity. As a basis for understanding this concept: f. Students know the greater the mass of an object, the more force is needed to achieve the same rate of change in motion. Density and Buoyancy 8. All objects experience a buoyant force when immersed in a fluid. As a basis for understanding this concept: a. Students know density is mass per unit volume. b. Students know how to calculate the density of substances (regular and irregular solids and liquids) from measurements of mass and volume. c. Students know the buoyant force on an object in a fluid is an upward force equal to the weight of the fluid the object has displaced. d. Students know how to predict whether an object will float or sink.

NETS: 

CREATIVITY AND INNOVATION: demonstrate creative thinking, construct knowledge, and develop innovative products and processes using technology.

COMMUNICATION AND COLLABORATION: communicate information and ideas effectively to multiple audiences using a variety of media and formats.

DIGITAL CITIZENSHIP: advocate and practice safe, legal, and responsible use of information and technology.

TECHNOLOGY OPERATIONS AND CONCEPTS: create original works as a means of personal or group expression.

 

Technology Tools Podcasts,

 

Procedures - 1. Students are to chose from the list of topics, of which they will create a 5 minute podcast about. The podcast will explain the concept and provide two examples of how to solve practice problems within the content. The idea behind this project is that students will pre-view, learn or review the material learned in class by listening from lessons created by fellow students. Need Windows 98/ME/2000/XP/Vista, within the lesson there is a link provided to download audacity - a program to help record and edit the audiocasts.
