Paul Andersen explains how energy is conserved within a system. In both macroscopic and microscopic collisions the amount of energy before the collision is equal to the amount after. He then defines heat as energy transfer between...

A video entitled "Winds Affecting Climate" which talks about how wind moves and affects climate.

A video entitled "How Climate Has Changed on Earth" which talks about Earth's fluctuating climate in the past.

Contrary to popular belief, temperature is not how hot or cold something is! This is a common misconception that many high school chemistry and science students have. In this video we will dive in to what temperature actually is and what...

We put aerogel to the test vs 'not-a-flamethrower', a huge 2000°C flame to a large fiberglass blanket infused with silica aerogel - formerly the lightest solid (that title is now held by graphene aerogel).

A set of well-defined lines within the electromagnetic spectrum, emitted by hot or excited matter.

Miss Palomine demonstrates to the student how to figure out words by using the letter sound relationships of the letters in the words and then putting those letter sounds together.

Miss Palomine talks about how retelling can make stories or poems much easier to understand. She then recites “Hot Summer Fun!” and helps the student retell the poem using familiar words and terms.
