An interactive applet and associated web page that demonstrate the definition of a line. The applet presents two points and a line that passes through them extending to infinity in both directions. As the points a re dragged the line moves but it is never possible to reveal a line end. See also the entries for line segment and ray. 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 definition of a line segment. The applet presents two points and a line that links them. As the points are dragged the line moves accordingly. See also the entries for line and ray. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that show the definition of a line segment in coordinate geometry. The applet has two points that the user can drag. The two points define a line segment, one for each endpoint. The grid, axis pointers and coordinates can be turned on and off. The applet can be printed as it appears on the screen to make handouts. The web page has a full definition of a line segment when the coordinates of the points defining it are known, and has links to other pages relating to coordinate geometry. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate a linear pair of angles. A pair of angles are shown and the user can drag the common side. It demonstrates that they a supplementary (add to 180 degrees) and have a common side. The angle measures can be turned off for class discussion. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet that allows the user to graphically explore the properties of a linear functions. Specifically, it is designed to foster an intuitive understanding of the effects of changing the two coefficients in the function y=ax+b. The applet shows a large graph of a quadratic (ax + b) and has two slider controls, one each for the coefficients a and b. As the sliders are moved, the graph is redrawn in real time illustrating the effects of these variations. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate a bisector of a line segment. The applet shows a fixed line segment and another line that bisects it. The second line's endpoints can be dragged, but the line adjusts itself so that it always bisects the fixed line. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that show the definition of a line in coordinate geometry. The applet has two points that the user can drag. The two points define a line, and the user can see how the line changes when the points are moved. The grid, axis pointers and coordinates can be turned on and off. The applet can be printed as it appears on the screen to make handouts. The web page has a full definition of a line when the coordinates of the points defining it are known, and has links to other pages relating to coordinate geometry. Applet can be enlarged to full screen size for use with a classroom projector.

A web page and interactive applet that illustrate the concept of locus. The applet shows a model of the plane populated with a large number of points on a grid. Those points equidistant form a point are highlighted, forming a circle in this case. The user can drag the point and drag the distance, showing the circle moving and changing size. The text page has a description of the locus concept and links to other loci - a straight line and an ellipse. Applet can be enlarged to full screen size for use with a classroom projector.

Can you avoid the boulder field and land safely, just before your fuel runs out, as Neil Armstrong did in 1969? Our version of this classic video game accurately simulates the real motion of the lunar lander with the correct mass, thrust, fuel consumption rate, and lunar gravity. The real lunar lander is very hard to control.

Do you want your class to be part of Canada’s Space program?

With the Lunar Rover Research Challenge, students could control a Canadensys rover in a mock-lunar environment by winning this low-prep, high-impact competition. Canadensys recently received a contract from the Canadian Space Agency to send a rover to the moon as early as 2026.

You can do the project in 3-4 hours for a classroom experience or 6+ hours to compete.

Game-based!

Lure of the Labyrinth is a digital game for middle-school pre-algebra students. It includes a wealth of intriguing math-based puzzles wrapped into an exciting narrative game in which students work to find their lost pet - and save the world from monsters!

The game gives students a chance to actually think like mathematicians.

> QU’EST-CE QUE L’ÉCOLE DE L’OCÉAN?
L’Université Dalhousie et l’Ocean Frontier Institute se sont associés avec l’Office national du film pour créer École de l’Océan, une expérience d’apprentissage par enquête gratuite et innovante.

À l’École de l’Océan, les apprenants explorent les habitats des fonds marins du golfe du Saint-Laurent au moyen de la réalité virtuelle. Ils se prennent en photo avec une baleine grandeur nature en réalité augmentée et dissèquent une morue virtuelle. Ils apprennent l’histoire de la morue racontée par un artiste autochtone dans une animation originale. Des vidéos à 360° les transportent dans des endroits qu’ils ne pourraient jamais visiter autrement, comme des forêts de kelp ou une île tropicale située à 550 kilomètres au large de la côte pacifique du Costa Rica.

L’expérience de l’École de l’Océan commence par une grande question posée aux élèves — un défi qui oriente leur enquête. Chaque élément média est accompagné d’une activité personnalisable que les enseignants peuvent attribuer par Google Classroom ou télécharger aux fins d’utilisation en classe. À la fin de chaque module, les apprenants élaborent un plan d’action visant à résoudre les problèmes sociaux et environnementaux auxquels ils ont été sensibilisés.

L'École de l’Océan donne à la prochaine génération de citoyens de l’Océan, de chercheurs et d’innovateurs les connaissances et les outils pour explorer et concevoir des solutions innovantes aux problèmes urgents auxquels font face les océans de la planète.

Si vous en êtes à votre première visite à l'École de l'Océan, vous devrez créer et confirmer votre compte ONF.

Ever wonder how a compass worked to point you to the Arctic? Explore the interactions between a compass and bar magnet, and then add the earth and find the surprising answer! Vary the magnet's strength, and see how things change both inside and outside. Use the field meter to measure how the magnetic field changes.

Explore the interactions between a compass and bar magnet. Discover how you can use a battery and wire to make a magnet! Can you make it a stronger magnet? Can you make the magnetic field reverse?

An interactive applet and associated web page that show the major and minor axes of an ellipse. The applet has an ellipse whose major and minor axis endpoints can be dragged. As they are dragged the major and minor axes change length and may swap places. The applet also shows the location of the foci, which are always on the major axis, and shows how they move with variation of the axis lengths. Applet can be enlarged to full screen size for use with a classroom projector.

This resource describes the physics behind the formation of clouds, and provides a demonstration of those principles using a beaker, ice, a match, hot water, and a laser pointer. 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.

In this short demo/activity, a balloon with baking soda in it is stretched over the mouth of a flask or bottle containing vinegar. The balloon is tipped so that the baking soda falls into the vinegar, and the reaction creates carbon dioxide, which inflates the balloon. The activity is part of the children's book, The Air We Breathe.

A realistic mass and spring laboratory. Hang masses from springs and adjust the spring stiffness and damping. You can even slow time. Transport the lab to different planets. A chart shows the kinetic, potential, and thermal energy for each spring.
