See how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics.
cK-12 Exploration Series offers Physics and Chemistry simulations to support visualization of abstract concepts. Teachers would need to create an account.
Explore how plates move on the surface of the earth. Change temperature, composition, and thickness of plates. Discover how to create new mountains, volcanoes, or oceans!
The result is an immersive, multimedia experience that brings players on a deep dive into key sequences and major science themes covered in the documentary and digital series. Using a combination of clickable 360 landscapes, 2D and 3D videos, animations, interviews with scientists, and mini-games, the Polar Lab takes players onto the ice and into the lab in search of evidence to answer big questions about Earth’s climate—past, present, and future. It also puts them in the driver’s seat, as they work with host Caitlin at “Polar Lab HQ” to collect data from the field, answer questions, and play games to keep the story moving through three action-packed missions…and what a story it is.
Une série de simulations provenant de l’Université de Colorado à Boulder pour les 9e – 12e au sujet des sciences.
«Les étudiants prédiront la polarité des liaisons en utilisant les valeurs de l'électronégativité ; indiqueront la polarité avec une flèche polaire ou des charges partielles ; classeront les liaisons par ordre de polarité ; et prédiront la polarité moléculaire en utilisant la polarité des liaisons et la forme moléculaire.»
An interactive applet and associated web page that demonstrate polygons. The applet shows a polygon which is initially an irregular convex pentagon. The user can drag any vertex and a message shows if it becomes concave. The user can also alter the number of sides from 3 to 99, the title changing to reflect it's name up to 12 sides. You can also make it regular, dragging a vertex then changes all vertices to maintain it as regular. The web page has many definitions and links to the various forms and orders of polygon. 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 that the exterior angles of a polygon always add to a constant (360 or 720 depending on your point of view). The applet shows a polygon where the user can drag the vertices to reshape it, alter the number of sides, make it convex or concave, regular or irregular. The applet shows the angle summation in real time, demonstrating that it is always constant. It also demonstrates how exterior angles are accounted for in concave polygons, where the exterior angle seems to be inside the figure. These are taken as negative angles and the sum demonstrably remains the same. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate that the interior angles of a polygon always add to a number related only to the number of sides. The applet shows a polygon where the user can drag the vertices to reshape it, alter the number of sides, make it convex or concave, regular or irregular. The applet shows the angle summation in real time, demonstrating that only the number of sides affects the total. The text on the web page gives the formula for the total of the interior angles. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate the diagonals of a polygon. The applet shows a polygon with the diagonals drawn. The user can drag any vertex, make it regular or irregular, and change the number of sides. The applet continually computes and displays the number of diagonals. The text on the web page has the relevant formulae. Applet can be enlarged to full screen size for use with a classroom projector.

An online game to learn about powering a city and the many different options there are for renewable energy.
A page that allows you to print rectangular (cartesian) graph paper. You ca control if grid lines are printed and the position of the origin. By dargging the origin into any corner a single quadrant can be printed. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

Travel back in time and explore the last standing ancient world wonder through Google Maps Treks. Learn more about the history, location, purpose, materials, and labor required to build the magnificent structures.
An interactive applet and associated web page that illustrate Pythagoras' Theorem. The applet shows a right triangle that can be resized by dragging any vertex. As it is being dragged the formula is continuously recalculated to show that the the theorem always holds for any right triangle. The formula can be turned off to facilitate classroom discussions. 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 quadratic equation. Specifically, it is designed to foster an intuitive understanding of the effects of changing the three coefficients in the function. The applet shows a large graph of a quadratic (ax^2 + bx +c) and has three slider controls, one each for the coefficients a,b and c. As the sliders are moved, the graph is redrawn in real time illustrating the effects of these variations. The roots of the equation are shown both graphically and numerically, including the case where the roots are imaginary. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page showing the properties of a quadrilateral. The applet shows a quadrilateral with draggable vertices. The web page has an extensive list of the various types of quadrilateral and links to other pages and applets illustrating each type.
