This video is recommended for use in conjunction with
Communication, Chapter 3, Is Anyone Out There?
Activity 4: The Electromagnetic Spectrum.

NASA film shows astronauts communicating with Earth. Students estimate the time delay between the signal from Earth to the response from the moon. Using this information, students calculate the speed of travel of a radio signal.

This video is recommended for use in conjunction with Medicine, Chapter 2, Vision. Activity 1: The Eye.

The videotape shows an actual lens implant procedure. Students view the surgery close-up in the same way as the ophthalmologist, wearing a magnifier, would see the operation. The camera is oriented so that the top of the patient's eye is at the bottom of the television screen. A complete description of each step of the surgery, as well as suggestions for discussion, are provided in the Teacher's Edition.

This video is recommended for use in conjunction with Medicine, Chapter 1, Hearing. It sets the scenario for the Chapter Challenge.

"Can't Hear You Knocking"© features prominent music entertainers talking about their hearing problems in order to encourage other music enthusiasts to avoid the same fate. Performers such as Ray Charles, Pete Townsend, Huey Lewis, Ted Nugent, Lars Ulrich of Metallica, and Mickey Hart of the Grateful Dead, as well as professional audiologists, sound engineers, and dedicated H.E.A.R. volunteers discuss how and why an increasing number of young people are suffering hearing losses and tinnitus from exposure to intense decibel levels of music. Their message is extremely convincing in the promotion of hearing protection. 55-minute version available through The Cinema Guild, NY, NY.

Here are the five video clips to be used with the activities in Sports:
Chapter 1: Activity 7: Increasing Top Speed
Students observe the distance traveled by a runner and measure the time taken to calculate the runner's speed. Students also count the number of strides taken by the runner during the time interval to calculate the runner's stride frequency.
Chapter 2: Activity 4: Defy Gravity
While the video is played in slow motion, students count the number of frames during which a figure skater and a basketball player are in the air. They use this information to calculate the hang time for each athlete.
Chapter 3: Activity 2: Free Fall on the Moon
Students view an astronaut simultaneously drop a feather and a hammer on the moon. They note that both land on the moon's surface at the same time.
Activity 6: Golf on the Moon
Students observe Alan Shephard's famous golf shot on the moon taken in February, 1970 to discover the potential problems of playing the standard game of golf on the moon.
Activity 8: Bounding on the Moon
Students examine footage of astronauts moving about on the surface of the moon. They discover that the astronauts use their legs to bound across the surface, rather than walk.

Here are the seven video clips to be used with the activities in Transportation:

Chapter 1: Activity 5: Intersections With a Yellow Light
A busy intersection is shown as the traffic light turns from green through yellow, to red. Students identify cars that did not need to stop for the yellow light, as well as cars that should have stopped for the yellow light. If an intersection with traffic lights is not available in your area, this video clip may also be used to answer Physics to Go, question 5. Measured distances from the intersection are marked in meters.
Chapter 2: Safety
The video illustrates a variety of different car crashes: head-on, rear-end, roll-over, and side-impact. Using crash-test dummies, the effectiveness of safety features such as head rests, seat belts, and air bags are also graphically demonstrated. Students are able to observe the advances in car safety by viewing a variety of collisions involving older cars This part of the video is suitable for use with a variety of activities in the chapter, as well as an introduction to safety.
Activity 9: Safety in the Air
Students who have never flown before will benefit from viewing this airline safety video segment. It outlines the type of safety equipment available on many aircraft.
Chapter 3: Activity 1: Weight Change During Takeoff
The effective weight change of someone standing on a bathroom scale in an elevator is demonstrated. Students identify the changes that occur as the elevator begins to rise, begins to descend, and rises and descends at a constant rate.
Activity 4: Life without Gravity
Life situations in zero gravity are detailed in a series of video segments. Astronauts are shown sleeping in cubicles as well as strapped down, washing long hair with rinseless soap, exercising, eating, drinking juice, splitting water droplets, and working with equipment. Students compare each activity they see with what happens on Earth.
Activity 5: Exercise on the Moon
Students examine footage of astronauts moving about on the surface of the moon on foot, as well as on a lunar rover. Students also view an astronaut simultaneously drop a feather and a hammer. They make observations about conditions on the moon.
Activity 8: The Speed of Radio Waves
NASA film shows astronauts communicating with Earth. Students estimate the time delay between the signal from Earth to the response from the moon. Using this information, students calculate the speed of travel of a radio signal.

Professional Development Videos

Dr. Arthur Eisenkraft, Project Director, presents a short overview explaining how and why Active Physics works.
Complimentary with the purchase of all six Professional Development videos.

Dear Educator:
"Imagine meeting someone who never heard of your favorite movie, book or work of art!
Now imagine how enriched they would be if they could enjoy them the way you do. Active Physics came about as a result of a similar frustration. The usual physics course has so much math and so much reading that many students miss the beauty, the excitement, and the usefulness of physics. Many more students simply refuse to take the course. Active Physics began when a group of physicists and physics teachers wondered how to pass on their enjoyment of physics to high school students. Physics should be experienced and make sense to all students. Each chapter of Active Physics begins with a challenge for them - develop a sport that can be played on the moon; build a home for people with a housing crisis; persuade their parents to lend them the family car; and so on. These are tough challenges, but your students will learn the physics that will allow them to be successful at meeting them.
Part of the education of students is to learn to trust themselves and to question others. When someone tells them something, can they answer the questions: "How do you know? Why should I believe you? and Why should I care?" After Active Physics, when your students describe why seat belts are important, or why loud music can be hazardous, or why communication with extraterrestrials is difficult, and someone asks,"How do you know?" their answer will be, "I know because I did an experiment." Active Physics awaits your students discovery. Enjoy the journey with them!"

Active Physics Professional Development Series

If a picture is worth a thousand words the Active Physics Professional Development Series is worth billions. Eight teachers who have actually taught Active Physics - who understand the needs of a teacher in the classroom - will take you step-by-step through each chapter, and every activity. The teachers will begin by discussing the opening Scenarios, Challenges, and the Criteria. They will then show you what materials you need, how to best use them, and how to best set up your labs. And, they will give you invaluable new teaching insights and tips that they themselves discovered while teaching the program. A great resource to always have at your fingertips. Even if you have been to a workshop on Active Physics, the videos are a valuable resource. Whether you watch them at home or in school, you can fast-forward to the exact spot you need. The videos are great for the experienced teacher as well as for one who is completely new to the program.
