Khan Academy: Change in Centripetal Accel From Chg in Linear Velocity & Radius

Is qualitative or quantitative research more convincing when it comes to climate change? In the eighth lesson during this 21-part series, scholars begin by performing a quantitative analysis of deforestation and urbanization. Then, they...

What is motion and why does it often follow a straight line? Share the video with your class so they understand the answers to this question and others. Pupils participate in discussions on displacement, acceleration, time, velocity and...

Build a strong foundation for your teaching of stability and change! The video addresses the Next Generation Science Standards Cross-Cutting Concept through insightful examples. The narrator includes ideas for introducing the standard in...

In this colorful animation, our current problem with climate change is likened to a block-stacking game of Tetris. Greenhouse gases are increasing in the atmosphere at an increasing rate. Can we place them properly before it's too late?...

Why does it take Pluto 90,000 days to orbit the sun, but it only takes Mercury 88 days? An interactive lesson helps pupils find a connection between the speed of orbit and distance a planet is from the sun. The simulation allows for...

Students investigate the climate changes occurring locally, regionally and globally over the last one hundred years. They brainstorm and predict whether the current year's weather was warmer or colder than last year then check the...

Energize your phase change lesson plans! Add a short but focused interactive into the mix and watch as pupils experience how states of matter react to changes in kinetic energy. The resource tracks the kinetic energy of a cold solid...

This is a specific heat capacity and enthalpy of vaporization example: calculating how much energy it takes to vaporize 1.00 kg of ethanol starting from 20 degrees C. [7:38]

Video lecture looks at oxidation and reduction in a biological context and compares it to a chemical context. [13:29]

Practice calculating change in momentum and speed from force vs. time graphs using this four-question quiz.
