No one has ever conclusively seen a proton turn into other, lighter particles, but fifty million liters of water in Japan might change that and our ideas about subatomic particles forever.

If you have ever torn up a piece of paper or seen ice melt, then you have witnessed physical changes. This fascinating program helps students understand some of the different ways matter changes physically. Vivid animations also...

This live-action video program is about the term change of state. The program is designed to reinforce and support a student's comprehension and retention of the term change of state through use of video footage, photographs, diagrams...

In this video Paul Andersen explains how chemical differs from physical change. In the laboratory macroscopic observations are used to infer changes at the particulate level. Evidence for chemical change include gas production, change...

Learn the basics about changes of state as part of the solids, liquids and gases topic within properties of matter.

What's the difference between a physical change and a chemical change? What are elements, compounds, pure substances, and mixtures? So many definitions to learn! Don't worry, Professor Dave will take you through the details.

Learn all about the most precious resource on this planet. It's not diamonds, gold or silver; it's water! Viewers will appreciate the staggering amounts of water used daily, the challenges ahead with physical scarcity versus economic...

Pirates love their coffee as much as they love their gold! But what does it take to get a good latte around here? Cookie the chef’s secret ingredient is cream, which he obtains by separating the components of milk. This lesson will...

Girls are taught all about the changes that happen to their bodies as they transition from child to adult. What is puberty? What are the physical changes associated with puberty? What is menstruation? What are the social and...

Mr. Andersen explains the difference between physical and chemical changes. A brief discussion of chemical reactions and equations is also included.

So when water evaporates, what happens? Where does that water go? Does just vanish? Is it no more? Can matter every just go away? Well, the answer is no, it can't. But it can LOOK like it does. In this episode of Crash Course Kids,...

This video is a lecture on specific latent heat, which looks at the energy absorbed or emitted by a substance as it changes states (solid, liquid, or gas). The lecture discusses two equations that can be used to calculate the amount of...

Learn all about the states of matter - solid, liquid and gas. We explain the concepts of freezing, melting, evaporation, and condensation, and discuss the reversibility of physical changes. We also distinguish between physical and...

This video explains the relationship between energy and changes of states in matter. It discusses the different changes of state, such as melting, boiling, and condensing, and the fixed temperatures at which they occur. The concept of...

Dr. Forrester teaches about photosynthesis and the functions of a plant’s stem.

Upon viewing the The Changing Phases of Matter video series, students will be able to do the following: Explain that phases of matter, also called states of matter, are the physical forms matter can take. State the four phases of...

In this segment, viewers uncover the four primary causes of water scarcity, from limited availability to contamination and poor management practices. Through engaging examples, students grasp the interconnectedness of these factors and...

You might have noticed that if you are trying to boil a lot of water it takes longer than if you only wish to boil a small amount of water. This is all because of something called ‘heat capacity’. Keep watching to learn more. Before we...

In this final segment, viewers explore how water filters offer multifaceted solutions to tackle the challenges of water scarcity. Delving into the latter causes outlined earlier, the video unveils the transformative potential of water...

The video explains the three main states of matter, which are solids, liquids and gases, and their properties. The concept of state symbols is introduced to indicate what state chemicals or particles are in a reaction. The video also...
