A flow chart of phase changes is marked with capital letters. A list of phase change terms is available to match with the letters in the flow chart. This is a unique approach to assessing your chemistry learners' grasp of these concepts....

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

Students explore the water cycle and associated phase changes. They predict what happens to the mass of an ice cube in a Ziploc bag, discuss and act out phase changes and diagram the water cycle.

Sixty multiple choice questions cover the entire gamut of chemistry concepts. This is the local section of the U.S. National Chemistry Olympiad, where your chemistry candidates take a shot at entering the national competition. They...

As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

This two-page assignment covers basic thermochemistry concepts. Chemistry learners identify exothermic and endothermic processes, explain a phase change graph, and draw an energy level diagram. There are no problems to solve, just...

In this phase change worksheet, students answer twenty questions about changes in energy to a system. They analyze phase diagrams, the determine the effects of changes in temperature on a system, they answer questions about miscibility,...

How does water pollution affect the environment? Provide your class with the resources to answer this question as they learn about eutrophication and ecosystem changes. Over two weeks, they simulate the effects of pollution on the...

Delve into the differences among solids, liquids, and gases with this PowerPoint. It is both applicable and attractive. Large, colorful diagrams display the molecular arrangement of each state of matter and their properties are arranged...

Students discuss how changing the structure of atoms and molecules can change the properties of a substance. They brainstorm and review their own examples of phase change with the help of a phase change diagram. Students describe the...

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

In this heat transfer and phase change worksheet, learners experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...

The phase diagram tops this chemistry quiz. Junior scientists answer eight multiple-choice questions as they analyze it and make calculations regarding the heat of vaporization. 

Ignore the full moon, it's just a phase. Young scholars observe and record the moon during a full cycle before learning to predict future phases. Then the instructor leads a discussion on the other solar system objects that...

View the moon changes from space while simultaneously experiencing the changes on Earth. A creative lesson allows pupils to view the big picture as they watch the orbit of the moon through a calendar period. At the same time, they see...

In this thermochemistry learning exercise, students indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Students...

A 30-question multiple choice chemistry test challenges takers. Topics touched upon include thermochemistry, equilibrium, behavior of gases, and pH. Problem solving is required in order to answer most of the questions. Other questions...

Students observe the melting of ice. In this phase change lesson, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.

Looking for a full-color, labeled water cycle diagram? You found one! From evaporation to precipitation to plant uptake and everything in between, it's all here and beautifully illustrated. 

In this phases worksheet, students rank the chemical compounds by decreasing vapor pressure. Students use a phase diagram to determine if water undergoes any phase transitions during the four steps described. This worksheet has 8...

In this physics worksheet, students examine how phase-locked loop circuits works and answer 8 short answer questions about it. They explain how FM radio communication works.

Five multiple choice questions are provided in the handout about the phases of the moon. A digaram is included to help astronomy learners answer the questions. The diagram is meant to represent the appearance of the moon from the...

In this phase diagram learning exercise, students answer questions about three given diagrams. They determine the boiling point, melting points and sublimation points for each substance. They also answer questions about the triple points...

Students investigate the properties of solids, liquids and gases. In this states of matter lesson plan, students observe dry ice and its characteristics. They calculate the density of dry ice and observe the sublimation of the dry ice...
