Students will predict bond polarity using electron negativity values; indicate polarity with a polar arrow or partial charges; rank bonds in order of polarity; and predict molecular polarity using bond polarity and molecular shape.

Do you ever wonder how a greenhouse gas affects the climate, or why the ozone layer is important? Use the sim to explore how light interacts with molecules in our atmosphere.

Une série de simulations provenant de l’Université de Colorado à Boulder pour les 9e – 12e au sujet des sciences.

«Vous demandez-vous parfois comment un gaz à effet de serre affecte le climat, ou pourquoi la couche d'ozone est importante ? Utilisez la simulation pour explorer comment la lumière interagit avec les molécules dans notre atmosphère.»

In this activity, students compute the strengths of the gravitational forces exerted on the Moon by the Sun and by the Earth, and demonstrate the actual shape of the Moon's orbit around the Sun. The lesson begins with students' assumptions about the motions of the Moon about the Earth and the Earth about the Sun, and then test their understanding using an experimental apparatus made from a cardboard or plywood disk and rope. 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.

Although it’s hard to replace the physical feeling of being inside the Canadian Museum of History, one virtual exhibit gives you the chance see a standout ceiling mural even closer than you can in person.
The circular painting, “Morning Star,” by Alex Janvier, decorates the ceiling of the dome of the Haida Gwaii Salon within the museum, towering above a bright white staircase. Online, you can zoom in on the mural and spin it to see the four quadrants in high detail. A click of the plus sign in the corner causes a series of links to pop up over the mural itself, with photos and videos attached that explain the significance of each part of the artwork.
Other exhibits listed in the museum’s “Online Exhibitions” section include a dedicated website explaining Inuit prints from Cape Dorset in Nunavut (with videos, interviews, pictures and interactive puzzle games to recreate prints yourself), and a clickable playhouse that has different “rooms” that lead viewers to different children’s toys from Canada’s past.

Learn about position, velocity, and acceleration graphs. Move the little man back and forth with the mouse and plot his motion. Set the position, velocity, or acceleration and let the simulation move the man for you.

Music Education apps to learn basic elements of music, including fast/slow, high/low, loud/soft, reading music notation, etc.

Mutations are mistakes in the DNA sequence. Use the Edit DNA button to change the entire sequence or click on an individual nucleotide to make an insertion, deletion or substitution mutation. How does changing the DNA sequence change the resulting protein? You can quickly jump between the DNA sequence and final protein by using the Show DNA and Show protein buttons. Are some types of mutations more damaging than others?

My Cree App is like learning Cree from your Auntie!

You are going to love how quickly and easily you begin speaking Cree. And you can start learning to speak Cree, right on your own iPhone or iPad.

Embark on an exhilarating journey across the cosmos as you unravel the intricate dance of planets, delving into the profound effects of position, mass, velocity, and distance on their celestial motions and orbits!

• Predict how the position, mass, velocity, and distance between planetary bodies affect their motion and orbits.

• Illustrate how the gravitational force controls the motions of the planets.

• Explore the different motions that a group of planetary bodies can have.

• Describe the behavior of the planet's velocity in different moments of its orbit.

Build your own system of heavenly bodies and watch the gravitational ballet. With this orbit simulator, you can set initial positions, velocities, and masses of 2, 3, or 4 bodies, and then see them orbit each other.

When scientists discover a new fossil skull, they compare it to skulls that have already been identified as particular early human species. In this activity, you get the chance to be the scientist!

"This page is for educators and students. The Native Plant Society of Saskatchewan is a strong advocate of nature education.

Find: Games, simulations, interactive prairie websites, posters, booklets, curriculum, lesson plans, coloring pages for local species.

In addition to the resources found here, we also support schools by:

providing free printed materials
leading field tours
delivering outdoor and classroom presentations
hosting opportunities to "ask an expert", where students can interact with a professional biologist or related occupation though in person events or Skype. In some cases, we can arrange for French-speaking experts.

We also support the establishment of native plant learning gardens on school grounds by offering free native seeds, printed resources, personal visits, presentations and expert advice to help with all stages of the process. The gardens can be as small as a square meter."

Using breathtaking photographs this virtual tour from the National Wildlife Federation takes students through the world as they learn about beautiful animals while also exploring ways to protect and conserve wildlife.

This virtual tour includes 5 activities and more nature activities to explore.

Produce light by bombarding atoms with electrons. See how the characteristic spectra of different elements are produced, and configure your own element's energy states to produce light of different colors.

A simulation of how neuron's in the body work along with how a signal is sent along a neuron.

A web page and interactive applet illustrating the properties of a nonagon (9 sided polygon). The applet shows a nonagon where the user can drag any vertex to reshape it. User can see that the interior and exterior angles are constant in a regular nonagon, but vary in an irregular version. Controls allow the display or hiding of the diagonals, and triangles within the nonagon. The web page lists the properties of a nonagon 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.
