Energy has many forms ... but very few sources! How do we present this to young scientists? Explore the Definitions of Energy, PS3A, in a video about the Next Generation Science Standards. The narrator keeps it simple by relating...

From burning wood for heat to riding a bicycle, converting one form of energy into another is an everyday process! Using a video clip, learners discover the sources of the thermal, mechanical, and electrical energies that make our lives...

Everything around you is related to chemistry and more specifically, the energy within a system. The video explores how energy, in its different forms, changes after conversion — given off as heat or absorbed as heat  in...

After Sam knocks a glass off the lunchroom table, he uses it as a springboard for explaining kinetic and potential energy. He mentions that sound is a type of kinetic energy and introduces the different forms of energy: thermal,...

When you're hot, you're hot! But, how does something get hot? Young scientists discover the properties of heat energy in an insightful video. The narrator discusses the differences between kinetic and potential energy, how heat transfers...

Kids sure do seem to have a lot of energy, but what exactly is energy? A video explains many different types of energy, starting with potential and kinetic. It highlights the most common forms of potential energy, including...

Why are neon signs so bright and colorful? Scholars discover how artists create neon signs and find out that neon is not the only gas they use in their production. Next, they explore the history of neon signs and how their development...

Sal's series on the Law of Thermodynamics continues with this video on how heat and work are added to, or taken away from, a system. As a result of the heat and work energy, the system that is being worked on will transform into another...

Explore thermal energy with this short episode. Jiggling molecules and hand-drawn animation help to explain that just because something has a lot of thermal energy, it doesn't necessarily feel hot to the touch. This is an ideal addition...

Many children's toys demonstrate energy transfer without electricity. The video highlights the drinking bird, which bobs up and down thanks to a chemical reaction. It also demonstrates other classic toys that show energy transfer...

A difficult-to-grasp concept, the fact that even cold objects contain heat energy, is the focus of this hot little video clip! Bill Nye tells physical science learners that heat is, by definition, the motion of molecules. He compares the...

Here is a special form of a sum of cubes problem, where students use algebraic multiplication to rewrite each term in expanded form. Sal gives an example before solving the problem to show the process that he will use to determine the...

In the eyes of a physicist, the purpose of life is to continue the mission of the sun. An engaging lesson discusses the increasing entropy levels of energy that originates at the sun. As life forms use that energy, entropy rises...

A forty story tower collects the sun's rays from a series of 600 mirrors and converts them into usable energy for the city of Seville, Spain. The video quality is poor, but the technology is amazing, making this worthwhile to show when...

Offering more than just light, a lamp can serve a dual purpose as a heater. The video shows that a lamp converts electricity to light and heat energy. Although the purpose of the lamp is light, most of the energy is in the form of heat....

Illuminate the world of mathematics for your class, specifically, the process of linear equations. In this video, Sal teaches about linear equations in standard form after two videos on slope-intercept and slope-point forms. He defines...

Many people study for years to understand even a subsection of chemistry, yet an informative video attempts to cover all of chemistry in 12 minutes. It starts with atoms and elements and moves through bonding, reactions, energy, and...

What happens when chemical bonds break and form? Science scholars explore the movement of energy in a chemical system by watching a well-rounded video. The narrators illustrate exothermic and endothermic reactions in terms of temperature...

What's driving the expansion of the universe, and will it ever stop? Take a trip to the dark side in a video full of surprising facts and twists about our view of what lies beyond. Junior cosmologists learn about the invisible energy of...

Imagine if scientists today were killed for their thoughts, ideas, and beliefs. And yet, Antoine Lavoisier was beheaded for just those things in 1794. Learn about this fascinating aspect of science along with the contributions of...

Take a look into the future of energy with a video that focuses on future alternative sources of clean energy. Viewers looks at various forms of biomass, hydrogen fuel cells, and nuclear fission and fusion.

An informative video explains the density of particles immediately after the Big Bang, as well as the concept that whenever a particle was released, it would merge with another particle. Sal develops the concept of being able to receive...

Atoms form relationships with other atoms, just like humans. Their relationships are called bonds and there are different types. Explore how energy is transferred between atoms through ionic and covalent bonds. 

Synthetic materials increase in popularity every year. Exploring Energy takes on the chemistry behind synthetic materials, including polyester. The resource opens with a video explaining the difference between natural and synthetic...
