Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

Energize your phase change lesson plans! Add a short but focused interactive into the mix and watch as pupils experience how states of matter react to changes in kinetic energy. The resource tracks the kinetic energy of a cold solid...

From gas to liquid condensation to solid frost, water undergoes phase changes before students' eyes! Using ice, salt, water, and a metal can, they set up an investigation that can be used in a physical science setting, or as part of a...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

Need a solid resource for teaching about states of matter? Science scholars go with the flow in a simple interactive that shows how intermolecular attractions determine a substance's phase. Pupils take control of the level of attraction...

If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...

The more things change, the more they stay the same. This unit includes seven lessons starting with physical change and moving through to chemical change. Conservation of matter is explained clearly with multiple hands-on activities and...

As a stand-alone or as part of the intended unit, this is a valid investigation of what causes condensation to occur.  By limiting the amount of air around a cold cup of water and comparing it to one out in the open, they find that...

Do charged and neutral particles behave differently as they undergo phase changes? Science sleuths examine two types of attractive forces using an informative interactive. Pupils can vary the amount of Van der Waals attraction present...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Pour on the knowledge with an engaging states of matter interactive! Young physical scientists view the atoms within a liquid to explain what gives a liquid its unique properties. The resource allows users to highlight and observe two...

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

Messenger's sun shade measures 8 ft x 6 ft and will have temperatures reaching 700 degree Fahrenheit on the outside while maintaining a cool 70 degrees underneath. In the third activity of four, groups discuss the basic properties of...

Welcome to the fast-paced life of a gas atom! Learners gaze at gaseous atoms up close using a colorful interactive. They can highlight two atoms and observe their movements within their container or follow the dizzying path of one atom...

Adjust the melting time of ice without varying the temperature! Learners experiment with different materials to decide how the materials affect the rate an ice cube melts. They then connect their findings to the conductivity of each...

Why are solids, well ... solid? Take a peek inside a solid substance with an easy-to-use interactive. Science sleuths examine the motion and position of the atoms that make up a solid before drawing conclusions from their observations.

How can you describe heat of fusion in a way the class understands and relates the importance of this concept to present day issues? In this third lesson of the series, learners conduct an experiment, demonstrating the flow of heat...
