The Essential Question in Physics: In what ways do I see energy moved and transformed in my every day life? The Project: Physics is the study of the physical world. The goal of physics is to use a small number of basic concepts, equations and assumptions to describe the physical world. Once the physical world has been described, physics principles can be used to make predictions about a broad range of physical processes. Because the physical world includes chemistry and biology, there will be some overlap in the examples you present. You must explain the physics!! Physics in Coordinated Science 2 will be divided into 3 broad topics as shown below. You will work with a team of students to collect digital pictures and videos that answer the Essential Question in each of the topic areas and assemble them into a 2 – 3 minute video. We will continue to learn how to assemble these images using Windows Movie Maker, add titles and voice narration explaining how the image illustrates an answer to the Essential Question. This project will be graded on how completely your team answers the Essential Question in each topic area, not on the quality of the video. Video and still pictures from phones and web cams will be good enough. Due Date: One week before the Semester 2 Final Exam What you will need: digital camera (phone camera is ok) that you can take video and still photos and download to your computer. (someone on your team needs to know how to do this.) microphone for a computer or digital recorder to record audio tracks over your video flash drive to store project – 512K or 1GB should be big enough. internet access – home or at school. Windows Movie Maker (free download). the everyday materials and objects you need to explain your ideas. Topic 1: Plate Tectonics and Earthquakes You know that the Earth’s crust is made of many separate moving plates. These plates move toward each other (converge), move away from each other (diverge), and slide past each other (transform) all over the Earth. When they move, sometimes volcanoes are formed, and earthquakes occur. When an earthquake occurs, energy is being converted – can you describe the change? We can’t predict earthquakes, so you are not expected to capture images or recordings of an actual earthquake. What you can do is study current events and incorporate earthquake events from around the world in your video. Include images, the epicenter location and the magnitude, on the Richter Scale, of each earthquake. Include the personal accounts of people that experienced the earthquake by making up a skit where one team member is a newscaster and another team member is being interviewed about the earthquake. Topic 2: Waves A wave is the motion of a disturbance. Some waves require mechanical medium to travel, like sound, and some do not, like visible light. In all cases, wave movement involves the transfer of energy from one place to another. The transfer can be longitudinal, parallel to the wave motion (sound), or the transfer can be transverse, or perpendicular to the direction of wave travel (visible light). When a wave travels freely, it is simply transferring energy. However, when a wave encounters an object or a different medium, its properties change and some energy is converted to another form. You know this because you have experienced the energy of the sun being converted to heat when it touches your skin. There are many examples of energy being transformed in modern living. Your job is to find them and explain them to us. Begin by listing the different forms of energy you know, and then find an example of each. More than likely, you will find that each source of energy is being created by transforming another type of energy. Be creative and use your imagination. Topic 3: Electricity & Magnetism The basis for electricity is in the fact that charged particles attract and repel each other. Remember your chemistry – like charges repel, and opposite charges attract. Every charged particle is surrounded by an electric field force, and we can use that fact to transfer charged particles through a conductor. This is called electricity, and it can be used to do work. (w =fd) Any time work is being done, energy is being converted from one form to another. For example, the charged particles moving through the filament of a light bulb have so much energy, they lose some as light and heat! Just as the interaction between charged objects can be described using electric fields, magnetism can be described by the magnetic field surrounding any magnetic particle. The modern uses of magnets is too long to list, and includes electromagnets (maglev trains), motors, loudspeakers, microphones, “old fashioned” magnetic recording devices like tapes, doorbells and even automatic car door locks! Almost all of these devices involve transforming energy from one form to another, and usual several different conversions. Figure out how the electromechanical devices in your life work, capture some images, and explain the physics. Grading Rubric: The overall project has a value of 100 points. You will earn points in each of the following categories according to the quality of your product: 100% Contains a wide variety of images that show thoughtful consideration of the question. 80% Contains many lackluster images that address the topics. 60% Many images are off topic. Narration connects the image with the essential question very well. Narration does not fully address the essential question or is off topic. Narration does not explain how the image is connected to the essential question. Topics are covered All 3 major topics are covered fully. 20 pts All 3 topics are covered, but one may be weak or partial. Less than 3 topics are addressed. Creativity Interesting, eyecatching and unique approach to the topics using original photography and audio. Mix of “canned” Basic treatment and original photos using clip art or and audio that are internet images. interesting but not unique. All members’ faces, voices and participation are obvious. One team member is missing from the project. Images address Essential Question 30 pts Explanation of the Physics 30 pts 10 pts Team Effort 10 pts More than one member is missing from the project.
