Sciences Grades 10-12

This video explores acids and bases and their proton-exchanging ways. Learn about the reactions happening in those solutions - atoms reorganizing themselves to create whole new substances.

Chemists need stoichiometry to make the scale of chemistry more understandable. This video explains why and how we can use stoichiometry.

This detailed interactive allows you to explore world data on carbon emissions in a variety of formats for comparison.

This is a virtual model of Earth's gyres and the pollution that flows through them.

This video uses the currency of subatomic particles to explain this unseen exchange. Acids actively give away their protons while bases actively collect them, some more aggressively than others.

Explore the interactions between two atoms. Turn on the force arrows to see the total force acting on the atoms or the individual attractive and repulsive forces. Try the "Adjustable Attraction" atom to see how changing the parameters affects the interaction.

Click on the globe to spin it. When you click on a location, you will see the latitude and longitude, as well as a visualization of global weather conditions. The weather is forecast by supercomputers and updated every three hours. The ocean surface current estimates are updated every five days.

There are three types of color receptors in your eye: red, green and blue. But how do we see the amazing kaleidoscope of other colors that make up our world? This video explains how humans can see everything from auburn to aquamarine.

"Marie Skłodowska Curie’s revolutionary research laid the groundwork for our understanding of physics and chemistry, blazing trails in oncology, technology, medicine, and nuclear physics, to name a few." Watch this video to learn about her amazing discoveries.

Universcale provides a look at objects from sub-atomic particles to red giants and all things in between using an interactive scale. This graphically beautiful tool is an outstanding way to measure and compare objects of different sizes.

This is an interactive map of Canada’s extensive clean-energy resources and projects. Clean energy includes renewable energy, electric vehicles, nuclear energy, biofuels, and carbon capture and storage (CCS).

The Government of Alberta's Oil Sands Information Portal provides information on the environmental impacts of oil sands development. The portal focuses on the cumulative effects of development in the oil sands region and has both an interactive map display and a data library.

In this video, the creator "examines the many ways in which energy cycles through our planet, from the sun to our food chain to electricity and beyond." (site)

Should you give your cooking oil a useful new life as biodiesel, a biodegradable energy source which can run in diesel engines instead of refined petroleum? This video describes the process of turning used oil goop into viable fuel.

Biofuels can provide energy without the reliance on environmentally harmful fossils fuels but scientists are still searching for a plentiful source. This video demonstrates how cellulose, the naturally abundant tough walls of plant cells, might be the solution.

This video examines renewable energy and some of the challenges of exchanging our fossil fuel dependence for only renewable energy sources.

In this animated video, the game board is Earth and all the Tetris blocks represent CO2, a greenhouse gas that is piling up as we burn fossil fuels. The video explains how this overload of CO2 leads to climate change and reminds us that, unlike Tetris, we won't get an opportunity to start over.

This video explains hydraulic fracturing, or “fracking,” that extracts natural gas from deep underground. How does fracking work and why is it controversial?

Is it possible that one day the world could be completely reliant on solar energy? This animated TED video examines how solar panels convert solar energy to electrical energy.

This animated TED video uses billiards to illustrate tipping points, chaotic motion and their implications on climate change. Learn about how rising CO2 levels in the atmosphere increase Earth’s temperature and lead to huge, unpredictable changes elsewhere.

Watch this animated video to learn how solar towers and panels work and why cloud cover is an important factor in the future of solar energy production.

A series of short animated videos that explain how systems in the body work. Created by a high school science teacher.

A series of short animated videos the explain the inheritance of traits and how they are passed using DNA.

How big are cells compared with other objects, molecules and atoms? Drag the slider button below the image to magnify the items.

This site provides high-quality images of bones and an interactive environment in which to examine and learn about skeletal anatomy. View the bones of a human, gorilla, and baboon and to gather information about them from the osteology database.

This animated simulation demonstrates the human immune system’s response to vaccination. After viewing the simulation, students can show what they learned by sequencing and labeling the steps in the process.

Learn about Koch's Postulates, basic principles that scientists use when trying to identify the cause of an infectious disease.

For several centuries, people thought diseases were caused by wandering clouds of poisonous vapor. This video describes how scientists worked to prove "germ theory" and changed how we see and prevent disease.

We know that germs are everywhere. Why are some of these germs relatively harmless, while others can be fatal? This video describes how germs are passed around and offers new ideas to control them.

Watch this animated video describing how Mendel's experiments with pea plants provided insight into genetics. Click on the Think button on the right for a short quiz.

This TED Talk video, with bonus quiz and resources, investigates how the heart "works by taking a closer look at the heart’s highly efficient ventricle system." (site)

This video takes an in-depth look at the science behind the sequence of letters that makes up an individual genome and technological advances that may help scientists understand genomes.

This video explores a very interesting theory. In the event of nuclear fallout or another worldwide catastrophe, every piece of digital and written information could be lost. Could all of human history be recorded and safely stored inside our human DNA?

Allison Ramsey and Mary Staicu detail the discovery of penicillin and how it transformed medicine.

This is a highly visual, narrated tour of the basics of DNA. Learn what DNA is and how it works in our bodies.

This visual and narrated tour of protein basics includes pain signals, cell scaffolds and making a protein.

This video explains the basics of genetics; learn about DNA, genes, chromosomes, proteins, and how genetic traits are inherited.
