Whether you’re a teacher or a motivated student, the materials provided here will be of use in the classroom or at your home desk. Most materials in this collection are related to physics, the physical sciences, or math. Some are great “rainy day” activities, others are mentally challenging puzzles, some are just plain fun. All are are based on sound pedagogical principles. And if you’re a substitute teacher, these are an excellent way to engage the class when you lack a lesson plan.
|Physics Lessons with 1080×810 Animations and Teachers Notes
Suitable for grades 8-12 Physical Sciences
|Redshift and Blueshift: Video demonstrates the relativistic Doppler effect for a binary star system of two equal-mass G type stars. Redshift and blueshift are exaggerated for clarity. The Teachers Notes explains the physics and math, and includes two practice problems with solutions.
|3-scene video showing the Doppler Effect for sound waves in air. This video includes an audio track, so you can hear the Doppler Effect in the animation, and also for the real-time footage of a trumpet playing a sustained note on a moving bus.
|Linear Orbit Simulation: This 2-scene video depicts a hypothetical orbit with eccentricity e = 1. Note: this never happens. Still, we can learn some interesting physics. It’s what’s called a gedankenexperiment (thought experiment). We place two identical Earths in mutual orbit around their barycenter. We position the Moon at a point equidistant from both Earths. Then we watch what gravity does.
We look at the resulting “orbit” from two frames of reference (points of view). First, we observe from a frame that is co-rotating with the two Earths. Second, we observe from a frame that is fixed in space and not rotating. The appearance is strikingly different.
|Riding a Wild Elevator: One 5-scene video showing how an observer’s state of motion affects their sense of apparent weight while riding an elevator. Our intrepid observer stands on a scale inside the moving elevator. Various rides ensue. Plots of velocity vs. time are displayed.
|Light Clocks, Time Dilation, & Length Contraction:
Three related videos introducing the topic of Special Relativity.
Video 1: The Light Clock (RT = 1:54)
We begin with Einstein’s concept of the light clock. Its behavior at rest differs from that when in motion. The second video presents the effect known as time dilation, and the third presents length contraction. This lesson is a basic introduction to Special Relativity. Four practice problems for students are included.
|Lightning and Thunder: One 3-scene video explaining how lightning forms and how it generates thunder. As a bonus, the Teachers Notes includes a discussion of lightning protection systems with relevant images.
|The Speed of Light: Two videos related to the speed of light. Part 1 shows an early attempt to measure that speed in the lab. Part 2 shows a real-time and to-scale animation of a laser beam bouncing off the Moon and returning to Earth. The Teachers Notes provide all the necessary background physics and math, as well as a brief history of attempts to measure the speed of light. One practice problem is included.
|Two videos showing how, at extreme latitudes, both the Midnight Sun and the Noon Darkness can occur. Both are caused by the tilt of Earth’s rotation axis with respect to the plane of its orbit around the Sun. Part 2 includes an animation of the rotating Earth explaining both phenomena, and a time-lapse photo of the Midnight Sun over Antarctica.
Part 1: The view from Barrow Alaska (RT = 3:51)
|This 2-scene animation shows several aspects of the Earth-Moon orbital system, including:
• Earth-Moon system to scale as seen from 1 million km out in space.
|The Science of Orbits: Four videos show how an “orbit” is a state of motion in which a body is continuous falling toward the Earth, but never getting any closer to the ground. This unintuitive concept is explained in a series of animations starting from basic kinematics. It begins with Galileo’s apocryphal experiment in Pisa, Italy.
|How We Make Electricity: Nine videos show how we make electricity from natural sources of energy. Video 1 explains the physics of electromagnetic induction. The following videos show how we harvest specific sources.
Video 1: The Generator (RT = 1:20)
Content for the Physics Classroom
|Applied Science Investigations: A collection of 36 one-page student investigations that can be used in class or as take-home assignments. They can also serve as a starting point for a science fair project. APIs span all areas of physical science including measurement, kinematics, energy, astronomy, waves, sports, as well as creative writing and math. All are classroom tested and students enjoy the challenges. Suitable for grades 6-12.
|Aptly named, this 10-unit manual reviews the mathematics science students need to know: algebra, trigonometry, vector analysis, proportions, statistics, graphing methods, units and conversions, scientific notation, significant figures, uncertainty, and the (basic) scientific calculator. Answers to the practice problems for each unit are included, as well as copyright-free masters for Cartesian, polar, semi-log, and log-log graph paper. Use it as an introductory unit or for reference. This is not an “easy read.” It is targeted for the serious student of science who is motivated to improve their mathematics skills. Suitable for grades 9-12.
|The International Dateline: Includes an animation (700×500@30 fps) and Teachers Notes. Students (and adults) often have questions about the International Dateline. The animation shows clearly how the Dateline works, why it is needed, and the effect it has on travel.
|USEFUL AT ALL GRADE LEVELS. A collection of printable graph paper with Cartesian, polar, semi-logarithmic, and logarithmic formats. Several different scales in each category.Stop throwing your money away at the bookstore and get this graph paper for the cost of toner and paper!
|780 Multiple-Choice Questions, MS Word document, 95 single-spaced pages. Classroom-tested questions (with answers) for physical science or physics. Can be used for in-class drill, review, or generating your own custom tests.
|The Five Optical Configurations of Telescopes: Five 320×480 animations showing how light moves through the five basic configurations of telescope optics. No text or equations — visual only. One page of teachers notes included. Suitable for grades 6-12.
|Produced under contract for General Robotics Corporation of Lakewood, CO, this curriculum package includes exercises designed around their RB5X Intelligent Robot. Interdisciplinary problem-solving activities are given for all grade levels. Students will answer essay questions, complete crosswords, solve math and physics problems, write programs, and design hardware solutions related to teleoperation. Mission to Mars includes a separate teacher’s manual with solutions. NOTE: This curriculum easily adapts to other robotics hardware and programming languages, since problem and solutions are presented as flowchart algorithms. Package includes both student and teacher versions, as well as HOW2RCL.pdf, a guide to the Tiny Basic programming language used by the RB5X. Adaptable for grades 6-16.
|This is a supplement for introductory physics courses. Part 1, Advanced Topics, covers areas often omitted from standard introductory texts: Archimedes’ Principle, orbital mechanics, relativity, SETI, bioenergetics, and friction. Part 2, Worksheets, includes engaging real-world problems (with answers provided) from kinematics, dynamics, kinetic theory, electricity, electromagnetism, and modern physics. Part 3, Appendix, contains just about every type of information a science student (or teacher) could need, plus copyright-free masters for Cartesian, polar, semi-log, and log-log graph paper. Suitable for grades 9-12.

This single-sheet handout explains (with diagrams) how to read a metric analog micrometer. It won’t look exactly like your micrometer but the instructions apply to all models, even those using imperial units.
|Taking good notes in a science class involves different strategies than what would be used in, say, a history class. This single-sheet handout describes the best methods for obtaining great science notes for each of three different classroom activities: traditional verbal lectures, sample calculation sessions, and multimedia (including demonstrations with apparatus). Suitable for grades 9-12.
