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....
Curated OER
States of Water
Students investigate the 3 states of matter. For this physical science "matter" lesson, students observe and participate in a number of demonstrations involving melting and freezing water. Students observe the effect heat has on changing...
University of Georgia
Freezing and Melting of Water
Examine the behavior of energy as water freezes and melts. An engaging activity provides a hands-on experience to learners. Collaborative groups collect data and analyze the graphs of the temperature of water as it freezes and then...
Curated OER
Water 1: Water and Ice
Students experiment with states of matter with water and ice. For this states of matter lesson, students experiment to discover what happens to water as it freezes to become a solid, ice. They observe what happens when ice melts back to...

Molar Heat of Fusion for Water
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...
Center for Learning in Action
Water—Changing States (Part 1)
Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...
Center for Learning in Action
Water – Changing States (Part 2)
Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...
Curated OER
Water and Ice
Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...
Curated OER
Disappearing Water
Learners explore the water cycle. In this earth science instructional activity, students observe and measure water in a closed container and in an open container. Learners record their observations and compare their sets of data to draw...
Polar Trec
Sea Ice Impact
The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...
Curated OER
Freeze Pops
Students experience problem-based learning as they use prior knowledge of the states of matter to keep a frozen juice bar from melting.

Changing States of Matter: Water’s Phase Changes
Third graders observe the properties of water and in its different states. In this states of matter lesson, 3rd graders view a video, read The Magic School Bus at the Waterworks and experiment with freezing, melting and boiling water to...
Santa Monica College
Introducing Measurements in the Laboratory
We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric...
Curated OER
Density Dynamics
Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.

Changes Caused by Heating and Cooling
It's heating up—and cooling down—in here! A hands-on lesson allows learners to experiment with melting and freezing butter to observe changes as a substance transitions between liquid and solid form. They also view an animation that...
Curated OER
Hydrologic Cycle Scavenger Hunt
Students explore the water cycle using educational resources. In this water cycle lesson, students use a global climate DVD to complete a scavenger hunt on the hydrologic (water) cycle.
Curated OER
Ice
Students examine the different propereties of ice, such as freezing temperature. In this scientific lesson students complete several activities using ice, like making ice cream.
Curated OER
Temperature Change and the States of Matter
Tenth graders observe the processes of evaporation, condensation, melting, freezing, boiling, and sublimation. They do a quantitative investigation of the freezing of water, to explore explanations that involve particles.
Curated OER
The Frigid Gourmet
Students make a " science surprise" or ice cream in the lab. In this melting point depression lesson plan, students use various substances with ice to determine the effects on the melting point of ice and the ability to make ice cream....
Curated OER
Edible Transformations
Learners differentiate the different phases of matter. In this chemistry lesson plan, students conduct several hands-on exercises to discover how matter transforms when mixed together. They identify the different stages in the water cycle.
Virginia Department of Education
States of Matter
Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to boil water through...
