This video will describe the history of the atom starting with Democritus and Aristotle all the way to Erwin Schrodinger and Louis De Broglie

Have you ever talked with a friend about a problem, only to realize that he just doesn’t seem to grasp why the issue is so important to you? Have you ever presented an idea to a group, and it’s met with utter confusion? What’s going on here? Katherine Hampsten describes why miscommunication occurs so frequently, and how we can minimize frustration while expressing ourselves better.

Learn how to tune, how to hold, how to strum, how to play your first four chords, a chord progression and use Justin's website to learn 100's of songs.

This video is for elementary age students and teaches students how to revise. The video was produced by students for students.

Looking for a powerful yet simple, low-tech way to integrate digital storytelling into your classroom? Then I’ve got an answer for you: Paper Slide Videos. Just like the name implies, this technique actually involves the sliding of papers to create a movie. Yep, without needing much time, effort and/or tech skills, a fabulous video can be produced. Here’s how:

S-wave shadow and P-wave detection patterns give us information about the core. Created by Sal Khan.

Discusses social, economic, political, and environmental push and pull factors dealing with human migrations.

This video segment adapted from A Science Odyssey looks at the invention of the automobile and the development of mass production.

Every school system is unique, but we are all connected by a shared aspiration: that all students have an educational experience that prepares them for success in college, in careers, and in life. Now more than ever, educators must not only provide rigorous academic content, but we must also be more intentional about fostering critical thinking, communication, collaboration, creativity, and other 21st century skills that our young people need to navigate this complex, rapidly changing world. Download this common cartridge file for professional learning on 21st Century Skills

You're in a movie theater, watching the new horror flick. The audience knows something that the main character does not. The audience sees the character's actions are not in his best interest. What's that feeling -- the one that makes you want to shout at the screen? Christopher Warner identifies this storytelling device as dramatic irony.

The "Into the Book" web site is designed to help elementary students practice eight reading comprehension strategies through playful interactive activities. The site focuses on eight research-based strategies: Using Prior Knowledge, Making Connections, Questioning, Visualizing, Inferring, Summarizing, Evaluating and Synthesizing. "Behind the Lesson," the teacher area of the site, provides information, lesson plans and other resources for teachers.

Students explore the basics of DC circuits, analyzing the light from light bulbs when connected in series and parallel circuits. Ohm's law and the equation for power dissipated by a circuit are the two primary equations used to explore circuits connected in series and parallel. Students measure and see the effect of power dissipation from the light bulbs. Kirchhoff's voltage law is used to show how two resistor elements add in series, while Kirchhoff's current law is used to explain how two resistor elements add when in parallel. Students also learn how electrical engineers apply this knowledge to solve problems. Power dissipation is particularly important with the introduction of LED bulbs and claims of energy efficiency, and understanding how power dissipation is calculated helps when evaluating these types of claims. This activity is designed to introduce students to the concepts needed to understand how circuits can be reduced algebraically.

The video introduces health challenges for the very varied group of migrants. A large part voluntarily migrated, but non-voluntary groups include refugees, IDPs, Stateless and trafficked persons. Internal migrants are both due to conflicts and disasters and general urbanisation. The different groups have very varied health issues, and also very varied protective frameworks – whether international conventions or national laws and services - and may not be able or willing to seek health care.

Khan Academy Grammarian David Rheinstrom welcomes you to his favorite topic: the study of language, its rules, and its conventions. By understanding English – by speaking it, by writing it, by reading this very sentence – you are a grammarian yourself!

Students will be introduced to irony with a focus on the three types of irony:  verbal, situational, and dramatic.  RL 8.4  Determine the meaning of words and phrases as they are used in a text, including figurative and connotative meanings; analyze the impact of specific word choices on meaning and tone, including analogies or allusions to other texts.Students will review the definitions of the three types of irony.  After viewing examples and taking notes, they will view three videos:  verbal irony, situational irony, and dramatic irony.Students will get a copy of the lyrics to the song "Ironic" by Alanis Morissette.  They will listen to the song a few times.and highlight examples of irony. Students will then work with a partner to share and discuss.  Next, students will type their own song lyrics using the song "Ironic" as a template portraying examples of irony.Students will then share with the class.  During presentations, students will highlight examples of irony using classmates' lyrics.
