What a fresh approach to learning about water! Chef Jamika Pessoa explains the chemical composition of this vital compound, what happens when heat is added or removed, and how much water is contained in different organs and...

Here is the recipe for making ice cream in a couple of zip-top plastic bags. It is a fun way to demonstrate phase changes, especially when the weather is hot! Use this in your elementary science curriculum when introducing the states of...

Steve Spangler has created a toy that relies on science to make ice cream! He uses a ball with two cylinders inserted. One contains rock salt and water, while the other contains the ice cream ingredients. Once sealed, a family kicks the...

Here is a fun display that will help your physical science fanatics understand freezing points and crystal formation. Use rock salt, sparkling water, and ice to create a -10¡C bath. Place full bottles of soda into the slurry to supercool...

Spangler leads an 11 year old scientist through the processes behind his science fair project, which was designed to see if any common household liquids (besides water) would expand when frozen. Liquids such as motor oil, ethanol,...

Create a cauldron of bubbling fun with this Halloween-themed demonstration idea. Using dry ice, Steve Spangler creates a crystal ball. If you compare the sublimation of dry ice to the melting of water ice, it is a wonderful way to...

A video lecture explaining specific heat, heat of fusion, and the heat of vaporization. See a step-by-step example of how to calculate the amount of heat needed to change the temperature of water. Also explored is the energy required to...

Defining specific heat, heat of fusion, and heat of vaporization, learn how to calculate the amount of heat to change the temperature of water and the energy required to change for a phase change. [14:57]

Become more effective in the classroom by watching this video on the common misconceptions student have about the weather, the water cycle, and phase changes. [8:40]

An extensive set of notes and graphics (excellent graphics) pertaining to the phases of matter, phase changes and the energy changes associated with changes in phase. Characteristic properties of solids, liquids and gases are discussed....

This lesson will provide an example of calculating the total amount of energy required for water to change from a solid at a temperature below zero celsius to a gas at a temperature above 100 degrees. A labeled phase change diagram will...

This lesson will define and locate the triple point and critical point on a phase diagram and illustrate how to extract other specific date points from the graph. It is 1 of 2 in the series titled "Reading a Phase Diagram."

This lesson will illustrate the energy changes that occur during changes of state by defining and using the concept of enthalpy. It is 2 of 2 in the series titled "Changes of State: Enthalpy."

This lesson will review the terminology of phase transitions. It is 2 of 2 in the series titled "Changes of State: Terminology."

How the heck do we map out a planet without oceans? NASA had to figure that out when we sent the Mariner 9 probe to Mars. There's some tricky, yet fascinating science behind all of it! In this video episode of Crash Course Physics, Shini...

In this Crash Course episode, Sabrina talks to us about matter and particles and that all matter is made up of particles. Also, she shows us how matter can change states from a solid to a liquid, a liquid to a gas, a gas to a solid, or a...

This animation explains what happens to particles when an ice cube melts or water boils.
