Congruent Angles
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

An interactive applet and associated web page that demonstrate the concept of congruent angles. Three angles are shown which always remain congruent as you drag any defining point on any angle. They all change together. This is designed to demonstrate that the angles are considered congruent even if they are in different orientations and the line segments making them up are different lengths. 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.

0.0 stars

An interactive applet and associated web page that demonstrate the congruence of polygons. The applet presents nine polygons that are in fact congruent, but don't look it because they are reflected and rotated in various ways. If you click on one, it rotates and flips as needed, then slides over the top of another to show it is congruent. The web page describes how to determine if two polygons are congruent. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate the concept of congruent triangles. Applets show that triangles a re congruent if the are the same, rotated, or reflected. In each case the user can drag one triangle and see how another triangle changes to remain congruent to it. The web page describes all this and has links to other related pages.

Distance from a point to a line using trigonometry
Rating
0.0 stars

An interactive applet and associated web page that demonstrate how to find the perpendicular distance between a point and a line using trigonometry, given the coordinates of the point and the slope/intercept of the line. The applet has a line with sliders that adjust its slope and intercept, and a draggable point. As the line is altered or the point dragged, the distance is recalculated. The grid and coordinates can be turned on and off. The distance calculation can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appears on the screen to make handouts. The web page has a full description of the concept of the concepts, a worked example and has links to other pages relating to coordinate geometry. Applet can be enlarged to full screen size for use with a classroom projector.

The Nrich game as introduced is intended for children who are just beginning to become confident with small numbers. However there are many variations, some suggested below, that make it suitable for older children. As with many of the NRICH games, consolidation of basic number facts is combined with an element of strategic thinking.

EJS Simulations by High School Physics Teachers
Conditional Remix & Share Permitted
CC BY-SA
Rating
0.0 stars

This web page features a collection of Easy Java Simulations developed by secondary teachers for use in introductory high school physics courses. Topics include astronomy, momentum and collision, projectile motion, Gauss's Law and electric field, special relativity, and more. Each simulation is accompanied by a standards-based lesson plan and printable student guides. Users may run the simulations as a Java applet or may directly download a jar file version. The materials in this collection were created with Easy Java Simulations (EJS), a modeling tool that allows users without formal programming experience to generate computer models and simulations. To modify or customize the model, See Related Materials for detailed instructions on installing and running the EJS Modeling and Authoring Tool. This resource is part of Project ITOP (Improving the Teaching of Physics), a graduate program offered at University of Massachusetts-Boston. The archived computer models are hosted and maintained as part of the BU Physics Simulation collection.

Elevator physics
Conditional Remix & Share Permitted
CC BY-SA
Rating
0.0 stars

The simulation illustrates the situation of a person in an elevator. The elevator takes the person from one floor to the next floor up.
For this situation, try sketching three free-body diagrams, one for the person, another for the elevator, and a third for the person-elevator system.
First, draw the diagrams for when the system remains at rest. Then, predict whether the free-body diagrams will change (and, if so, how) when the elevator is accelerating up, moving up at constant velocity, and moving up but slowing down (acceleration is down).

The simulation draws the diagrams for all these cases, but make sure you try drawing your own before looking at the simulation's diagrams.

An interactive applet and associated web page that demonstrate the equation of a line in point-slope form. The user can move a slider that controls the slope, and can drag the point that defines the line. The graph changes accordingly and equation for the line is continuously recalculated with every slider and / or point move. The grid, axis pointers and coordinates can be turned on and off. The equation display can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appears on the screen to make handouts. The web page has a full description of the concept of the equation of a line in point - slope form, a worked example and has links to other pages relating to coordinate geometry.
