An introduction to Refraction in Water. Created by Sal Khan.
Resistors that come one after another. Created by Sal Khan.
This seminar is intended to help students in the MIT/Woods Hole Oceanographic Institute Joint Program develop a broader perspective on their thesis research by considering some aspects of science in the large. The first part of the course challenges students to develop a thoughtful view towards major questions in science that can be incorporated in their own research process, and that will help them articulate research findings. The second part of the course emphasizes science as a social process and the important roles of written and oral communication.
Explanation of the second law of thermodynamics.
What happens when there's only one hole? Created by David SantoPietro.
Snell's Law Example 1. Created by Sal Khan.
Snell's Law Example 2. Created by Sal Khan.
In this video David explains what specific gravity means. He also shows how to calculate the value for specific gravity and use it to determine the percent of an object that will be submerged while floating.
An introduction to Specular and Diffuse Reflection. Created by Sal Khan.
An introduction to Specular and Diffuse Reflection, part 2. Created by Sal Khan.
Thinking about the coefficients of static and kinetic friction. Created by Sal Khan.
What happens when sugar and salt are added to water? Pour in sugar, shake in salt, and evaporate water to see the effects on concentration and conductivity. Zoom in to see how different sugar and salt compounds dissolve. Zoom in again to explore the role of water.
