It's Halloween night and Jessi and Squeaks just got home with loads of candy! Before they dive in, though, they want to learn a little more about how one of their favorite types of candy is made!

In this video Paul Andersen explains how energy flows in ecosystems. Energy enters via producers through photosynthesis or chemosynthesis. Producers and consumers release the energy from food through cellular respiration. An explanation...

In this video Paul Andersen explains how energy can neither be created nor destroyed but may be transferred. Energy comes in many forms (including chemical, mechanical, light, electrical, and thermal). In AP Chemistry students must be...

In this video Paul Andersen explains how energy can be transferred from one system to another. In a closed system the energy can be transferred as either work or heat. Thermal energy transfer is know as energy transfer through heat....

In which John Green, Hank Green, and Emily Graslie teach you about our Sun, and the formation of the planets. We're going to focus on the formation and development of the Earth, because that's where people live. You'll learn about the...

The planets in our solar system have a very specific order. But have you wondered why they have the order they do?

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...

Why is it Hot Underground

From 2016 to 2019, the world saw record-breaking heat waves, rampant wildfires, and the longest run of category 5 tropical cyclones on record. The number of extreme weather events has been increasing for the last 40 years, and current...

Explore the four inner rocky planets, as Jessi and Squeaks take you on a tour of the solar system!

New ReviewWelcome back to the Fluctus Channel, as we discover how Nigeria turns waste tires into bricks, slippers, and mats, and explore Sweden’s SYSAV plant where waste becomes energy and sustainability. Fluctus is a website and YouTube channel...

Benjamin Franklin was more than a founding father—he was an inventor with a curious mind and a knack for solving everyday problems. From bifocals to the lightning rod to the Franklin stove, his creations improved lives in both small and...

What causes the rate of reaction.

How temperature affects particle motion.

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

A video entitled "Polluting of the Atmosphere" which talks about the negative effects of pollution.

This video explains how nuclear fusion occurs in stars and causes them to shine.

This video explains heat transfer methods of radiation, conduction, and convection.

Two minute video for middle school on the causes of climate change

2 minute video giving a brief overview of plate tectonics, for middle school science

For the last 50 years, Americans have flocked to the warm, sunny South. But, as climate change makes extreme heat, hurricanes, wildfire and flooding worse, will that trend ever STOP? Well, some regions might just be showing signs of a...

We know that the Urban Heat Island Effect can make cities particularly vulnerable to extreme heat, but a new study uncovered something even more surprising: cities might actually be able to attract, and even CREATE, storms. In this...

Heat is the deadliest weather hazard in the U.S. and many places around the world, and it's only getting worse. The most deadly heat waves so far have been dry heat waves. But a new threat is rising: humid heat waves, aka wet-bulb...

In quantum mechanics, it’s just as natural to go forward in time as going backwards. And if you look at a typical Feynman diagram, you can turn the diagram either way. Where does this transition from time symmetry at the quantum level,...
