Students will understand the following: 1. Static electricity is the cause of lightning. Lightning forms because of an accumulation of electrical charges inside a cloud due to friction from dust, ice, and water droplets. The bottom of a cloud becomes negatively charged and discharges a lightning strike when enough charge has built up. Groups will need the following materials for their demonstrations:.
Group 1: ground pepper; plastic utensil, such as a knife or a comb; wool or nylon cloth. Group 2: plastic comb, piece of wool or fur, metal doorknob.
Group 3: two rubber balloons. Group 4: plastic combs, bowl of puffed rice 1. Review with your students what they know about cloud formation, thunder, and lightning storms. Tell them they are going to perform a series of simple demonstrations that will show how an accumulation of electrical charges inside a cloud causes a lightning strike. Divide your class into small groups. Have each group perform one of the following demonstrations for the rest of the class. Demonstration 1:.
Spread grains of ground pepper on a small area of a desktop. Vigorously rub a plastic utensil with a wool or nylon cloth to produce a negative charge. Hold the utensil about 1 inch over the mixture and observe what happens. (The utensil will pick up the pepper.) 4.
Demonstration 2:. Darken the room as much as possible. Rub a plastic comb with a piece of wool or fur. Hold the comb near a metal doorknob.
Observe what happens. (Students will see tiny sparks.) 5. Demonstration 3:. Blow up two balloons and rub them on your sleeve. Darken the room as much as possible. Rub the two balloons together. Observe what happens.
(Students will see tiny sparks.) 6. Demonstration 4:.
Run a comb through your hair (only one student should use each comb). Put the comb into a bowl of dry puffed rice. Observe what happens. (Grains of rice will stick to the comb; after they lose their charge, they will fall off.) 7.
After each group has performed its demonstration, explain that in each case, friction created a buildup of electrons, causing an electrical charge. This is known as static electricity. Tell students that in a storm cloud, friction from dust, ice, and water droplets produces an accumulation of charges, as did the friction in each of the demonstrations. It is this static electricity that causes lightning. Have each student write a paragraph describing the demonstration his or her group performed and what group members observed. Paragraphs should be accompanied by illustrations and labeled diagrams. Invite students to share their explanations and illustrations.
Share with your class the following explanation of lightning from Simple Weather Experiments with Everyday Materials, by Muriel Mandell (Sterling Publishing Company, 1990): The violent air currents in thunderclouds move different-sized drops and dust particles at different speeds. Those of the same size and with similar amounts of electricity get concentrated in the same part of the cloud. A very high positive electrical charge is formed in the cold higher parts, while near the ground the thundercloud usually is negatively charged.
The big difference between the charges at the top and bottom of the cloud creates a powerful voltage or electric pressure. This 'push' sends a flash of lightning streaking through the cloud between those parts with opposite electric charges.
Adaptations for Older Students: Rather than explain the causes of lightning to the class, have each student do research on the causes of lightning and write a brief paragraph explaining the physics behind a lightning strike. Examine the development of a lightning bolt from small charge to discharge. Explain the phases in the life of a lightning bolt. Develop an idea for capturing and using lightning as a power source. What areas of the world would most benefit from such a device?
Explain what type of structure you would choose as shelter during a lightning storm. Include reasons for your choice. Keeping in mind that Ben Franklin didn't invent or discover lightning, write a letter from Mr. Franklin to George Washington detailing your experiment and the things you learned.
Explain to Mr. Washington how your lightning bells work and of what use they have to households in the new country of America. Mary Shelley speculated that a person could be made from parts of dead people. In her book Frankenstein, a mad doctor assembled people parts into a personlike shape, then brought it to life with lightning. Knowing what you now know about lightning, debate whether or not this would really work.

Intro & Objectives for the course: In this lesson plan, I will be walking you through the process of implementing a weather forecast video broadcast for your student run television production class. The final production will cover a wide range of real world techniques and examples and will teach your students how to create, manage and produce a professional weather forecast to insert into your news production. This lesson plan is designed for novice to advanced students and can be implemented in a variety of ways.
Depending on the complexity of the final product you seek, this production can be tailored to the experience of your students and staff. By the end of the lesson, your students will learn how to act as a part of a television news team, gather information from outside sources, create custom graphics and package the final information into a weather forecast production ready for distribution. Materials List - 5 or more students - Internet connected computer capable of video editing - Video editing software (Final Cut Pro, Premiere Pro or other advanced video editing software recommended) - Adobe After Effects Software (optional) - Green Screen Studio/Backdrop (optional) - HD Video Camera or DSLR with Video Capability How to introduce the lesson to your students Start, by introducing the idea of a weather forecast to your students. You can show them video clips of professionally created local or national weather forecasts.
Discuss with them the main elements of a good weather forecast and how a weather forecast works. You can also explain to them the importance of meteorology and how a weather data is created by a team of weather forecasting experts. Next, let them know that you will be helping them to produce and execute a local weather forecast for your video production class. Here are the recommended main steps of the class (but these can be adjusted based on your overall class goals): Step 1: Decide what kind of forecast you would like to produce There are a variety of types of weather forecasts that you could produce with your students. You can create a 5 day weather forecast, 7 day weather forecast, current day's forecast as well as use graphics for map projections and almanac type information. Include your students in the decision of what type of production you would ike to create.
Then, determine the elements of your weather forecast production to get an idea of the graphics and information elements you will need for your production. Here is a list of typical elements of a typical weather forecast: - 1 Student Meteorologist (who will deliver the weather forecast) - 5 Day Weather forecast - 7 Day weather forecast - Today's weather - Weather Almanac - Local Map Weather Projections Step 2: Gather students and assign roles This varies depending on your production, but here are the typical roles you can assign to students (these roles can be doubled up depending on the number of students in the class): - Meteorologist: Delivers the weather forecast on (and off) camera. May stand on a green screen or chroma key background to deliver the forecast if you have one. Researcher: Researches the upcoming weather events and data and compiles information for the weather forecast. Script Writer: Takes weather information from researcher and composes a script that the meteorologist will read on the air. Camera Operator: Operates the camera during the production - Motion Graphics Designer: Compiles the information from the researcher and script writer and creates weather forecast graphics with the data provided - Tele-prompter Operator: (optional) Operates the teleprompter which displays the script for the meteorologist to read on the air.
Floor Director: This can be a student or the teacher. This person is in charge of the production and directs the broadcast. Step 3: Producing the graphics There are multiple ways to create weather graphics for your production.
If you have the ability, time & talent, you can build your graphics from scratch in Adobe Photoshop or a motion editing program such as Adobe After Effects. A good way to save time and energy is to start from an existing graphics template and customize as needed. In this example, we will be using an existing weather forecast template: (weather template video) This template is available for purchase in quicktime format and Adobe After Effects format. The After Effects template is recommended, since it is the most customizable, however, if your class does not have After Effects, the Quicktime versions can be used with most video editors on the market. Step 4: Adding the weather data Next, I will walk you through how to add weather data to your graphics and customization of the weather graphic template.
For this example, I will show how to create a 7 day forecast and customize it with data that has been gathered. IN ADOBE AFTER EFFECTS: 1. Open Adobe After Effects and open the weather forecast After Effects Template 2. Open the composition 'RENDER7 DAY FORECAST' Within this composition, you will see a number of layers that make up the animation. The second layer in this composition is 'EDITWeather'. Arch models vol 45. Double click this layer composition (or double click it in the Project window).
This will open the 'EDITWeather' composition which is where you will arrange the various weather icons and enter the temperature data. In this composition, you will see the first 7 layers are the various animated weather icons: thunderstorms, overcast, clouds, partly sunny, snowy, rain & sunny. You can shift the weather icons and move them to various days by selecting them on the timeline and using the arrow keys.
Also, if you need more than one of an icon (let's say you have 2 days of sunny forecast), you can duplicate an icon by selecting it on the timeline and pressing ctrl+d or by selecting the icon and going to EDIT-Duplicate on your top menu. Re-arrange the icons on the 7 day forecast and duplicate icons as needed. Icons which are not needed can be hidden by clicking the eyeball icon next to the layer: 5. Next, lets change the temperature data for each day. Layers 8 - 14 are titled 'EDITfriday' - 'EDITSaturday'. These compositions contain the temperature text data. Simply double click the day you would like to edit: Then, select your text tool (or double click the text layer you would like to change), select the text you would like to change and enter the correct weather data you would like to change.
Do this for each day in your forecast. Now, return to the main composition 'RENDER7 DAY FORECAST'. If you entered your data correctly, your composition should display your forecast with the correct weather data and icons. To render the composition to a movie, select composition-make movie from your top menu (or ctrl-m). Render the movie in whatever format is needed for your final video editor or live DVR player. Within this template, you can also edit a 5 day forecast, Almanac & Today's forecast using the same techniques learned from the 7 day forecast.
Also, you can add and remove layers from the template to customize the forecast with your own logo, colors and graphics. IN ADOBE PREMIERE (or another video editor such as Final Cut Pro) 1. Open your video editor (in this example, we will be using Adobe Premiere Pro) 2. Import 'motionweatherblank7Day.mov' and 'motionIconsalpha.mov' into your editor and place 'motionweatherblank7Day.mov' on your timeline. Drag 'motionIconsalpha.mov' onto your timeline. This file contains all of the animated icons in your project.
You will need to isolate each icon separately so you can re-arrange and order the icons as your forecast needs. Apply a crop to your weather icons clip to isolate each icon: Before cropping: After Cropping: Isolate and crop each animated icon needed in your forecast by duplicating the clip on the timeline and isolating each element with cropping. Once you have all of your icons isolated on the timeline, add them into layers above your 'motionweatherblank7Day.mov' layer: Scale and position your animated icons and place them into position on the 7 day forecast background.

Next, add a text layer to your composition. In premiere, go to FILE-New-Title to create a text layer. Add and style your text content to enter your forecast temperature data: 7. Save this file (you can now use it as a template to create further forecasts without having to recreate the icons or temperature data every time). When you have all of your data and icons in place, export your final movie into whatever format is needed in your production pipeline.
Step 5: Recording the Broadcast Now, you can record your meteorologist explaining the 7 day weather forecast. This can be done simply with audio as a voiceover, or you can shoot video of your talent on a chroma key background and composite them into the scene: This can be done in post production or live if you have the necessary hardware and software setup to do live chroma keying. If you have a script and teleprompter, the on air talent can read from the teleprompter. Step 6: Distribution of the Broadcast Once you have created your final packaged forecast, you can distribute the video to your broadcast playback device or online (or live if you are creating a live broadcast production). Either way, you will have a professional weather production that can be used in a variety of ways. Step 6: Review Creating a professional weather broadcast production is a challenge and can be an excellent learning experience for your students.
