Phase Changes of Water
A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

Water Cycle Stories
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.
Curated OER
Water and Ice
Students will observe, measure and describe the phase changes of ice. In this science lesson plan, students observe ice as it changes phases. Qualaitative notations made by individual students will be shared and compared.

Solid, Liquid, and Gas
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...
Curated OER
Heating Curve
Wow! This is a nifty presentation for teaching high school chemists about the heating curve. It displays a graph for temperature vs. heat added, then enters the curve itself. The final slide identifies each part of the curve. Notes are...
Curated OER
Phase Change Flow Chart
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....
Curated OER
Edible Transformations
Students differentiate the different phases of matter. For this chemistry lesson, students conduct several hands-on exercises to discover how matter transforms when mixed together. They identify the different stages in the water cycle.
Curated OER
It's The States of Matter
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...
