Play with a 1D or 2D system of coupled mass-spring oscillators. Vary the number of masses, set the initial conditions, and watch the system evolve. See the spectrum of normal modes for arbitrary motion. See longitudinal or transverse modes in the 1D system.

In this experiential activity, students demonstrate to themselves the effect of the optic disc, or blind spot, inherent to the optic nerve entering the posterior of the eye (bulbus oculi). This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Start a chain reaction, or introduce non-radioactive isotopes to prevent one. Control energy production in a nuclear reactor! (Previously part of the Nuclear Physics simulation - now there are separate Alpha Decay and Nuclear Fission sims.)

Numeracy is having the confidence and habits of mind to use mathematics to meet the general demands of everyday life. Being a numerate person means using mathematics to make sense of something new and know what mathematics can and cannot do.

Numeracy provides First Nations, Métis and Inuit students the opportunity to discover connections on their own and apply strategies to solve real life problems. Throughout history, First Nations, Métis and Inuit peoples have used real life traditional learning contexts to connect to their world.

In the Empowering the Spirit video series, students explore numeracy through Traditional Games, an elementary math class on probability and a high school physics class examining the structure of a tee pee and rocket nozzle.

An interactive applet and associated web page that demonstrate obtuse angles (those between 90 and 180 deg). The applet presents an angle (initially obtuse) that the user can adjust by dragging the end points of the line segments forming the angle. As it changes it shows the angle measure and a message that indicate which type of angle it is. There a software 'detents' that make it easy capture exact angles such as 90 degrees and 180 degrees The message and angle measures can be turned off to facilitate classroom discussion. The text on the page has links to other pages defining each angle type in depth. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

An interactive applet and associated web page that demonstrate the three types of triangle: acute, obtuse and right. The applet shows a triangle that is initially obtuse (one angle greater than 90 degrees) which the user can reshape by dragging any vertex. There is a message changes in real time while the triangle is being dragged that tells if the triangle is an acute, right or obtuse triangle and gives the reason why. By experimenting with the triangle student can develop an intuitive sense of the difference between these three classes of triangle. Applet can be enlarged to full screen size for use with a classroom projector.

A web page and interactive applet illustrating the properties of a octagon (8 sided polygon). The applet shows an octagon where the user can drag any vertex to reshape it. User can see that the interior and exterior angles are constant in a regular octagon, but vary in an irregular version. Controls allow the display or hiding of the diagonals, and triangles within the octagon. The web page lists the properties of an octagon including interior angles, exterior angles, sum of exterior angles, area, number of diagonals and number of internal triangles. Links to pages with generalized properties of all polygons. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

An online simulation for seeing how colour and the mixing of colour looks like on a stage and on the actors.

Online Statistics: An Interactive Multimedia Course of Study is an introductory-level statistics book. The material is presented both as a standard textbook and as a multimedia presentation. The book features interactive demonstrations and simulations, case studies, and an analysis lab.

OpenGrade is open-source software for teachers to keep track of grades. It runs on Linux, as well as some other operating systems.

An interactive applet and associated web page that demonstrate opposite rays. The applet shows two rays with a common endpoint and can be dragged with the mouse. If the rays are in a line, the message 'Opposite rays' appears. A detent makes it easier to get them perfectly aligned. Applet can be enlarged to full screen size for use with a classroom projector.

Explore an active area of research in optical physics: producing designer pulse shapes to achieve specific purposes, such as breaking apart a molecule. Carefully create the perfect shaped pulse to break apart a molecule by individually manipulating the colors of light that make up a pulse.

Did you ever imagine that you can use light to move a microscopic plastic bead? Explore the forces on the bead or slow time to see the interaction with the laser's electric field. Use the optical tweezers to manipulate a single strand of DNA and explore the physics of tiny molecular motors. Can you get the DNA completely straight or stop the molecular motor?

A web page and interactive applet demonstrating the concept of the orthocenter of a triangle. The applet shows a triangle where the user can drag the vertices around. The orthocenter and the altitude lines that generate it are continuously moved as the user drags the vertices. By experimentation the user can observe that the orthocenter can be inside or outside the triangle. The page text explains the definition of the orthocenter and how to find it. Applet can be enlarged to full screen size for use with a classroom projector.

This is a collection of outreach resources about the Sun that are meant to be used in informal education settings. This toolkit was originally designed for NASA Night Sky Network member clubs and the Astronomical Society of the Pacific's Astronomy from the Ground Up network of museum and science center educators. The toolkit includes background information about the Sun, magnetic fields of the Earth and Sun, and space weather, activity suggestions, and detailed activity scripts. The themes of this toolkit address both the constant nature of the Sun as a reliable source of energy and the dynamic nature of the Sun due to its changing magnetic fields. The activities and related materials in this collection include The Sun in a Different Light - Observing the Sun, Explore the Sun cards, Magnetic Connection, the Space Weather PowerPoint, Protection from Ultraviolet, and Where Does the Energy Come From cards. These activities can be done separately or as a group as part of an informal education event. Institutions that are not part of the Night Sky Network will need to acquire the various materials required for each activity.

"This Web module enables intermediate students to experience life in the trenches during the First World War. Part history and part adventure story, Over the Top allows players to determine the outcome of the story by making decisions at key moments. This educational resource includes follow-up activities, maps, films and document references."

All the students in our school have iPads and I recently had received 2 LEGO robotics kits; I wanted to find a way to mesh the two together. LEGO has a free app (for iPads only) that allows students to program their robot and connect to it via Bluetooth. The goal of this assignment is to learn about basic function of the LEGO EV3 robot. This includes the motor, color sensor and ultrasonic sensor. The main objective is to learn how to program, or "code", the robot to perform various functions using the "LEGO Mindstorms Programming App".

The VRTEX® systems are virtual reality arc welding training simulators. These computer based training systems are educational tools designed to supplement and enhance traditional welding training. They allow students to practice their welding technique in a simulated and immersive environment. The VRTEX® systems promote the efficient transfer of quality welding skills and body positioning to the welding booth while reducing material waste associated with traditional welding training. The combination of realistic puddle, arc welding sound, and real time feedback tied to the welder’s movement provides an exciting, hands-on training experience.

This document provides details and ordering information on the VRTEX® 360.
