It's Freezing!
Here is a good learning exercise for 5th grade scientists. In it, they look at a bar graph that shows the freezing point for a variety of liquids. Then, they are given a scenario of a certain liquid melting and freezing, and must...
Curated OER
Water and Ice
Students observe and discuss what happens when water turns to ice and when ice turns into water. In this freezing and melting lesson plan, students observe ice and water and complete hands on activities that change their properties.

Energy and States of Matter
Characteristics of each state of matter are listed, the formulas for heating water are detailed, and values for boiling and heat of vaporization are presented. This simple slide show provides direct instruction as well as practice...
Curated OER
Freezing Point Depression
Students create ice cream in a zipped bag and measure the temperature of a salt/ice mixture. They discover how salt lowers the temperature necessary to freeze ice to a solid (below 0'C).

Changes Caused by Heating and Cooling
It's heating up—and cooling down—in here! A hands-on instructional activity 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...
Concord Consortium
Specific Heat and Latent Heat in Condensation
There's more to melting than meets the eye! Junior physical chemists investigate the differences between specific and latent heats as a substance undergoes a phase change. Users remove heat from the system and observe changes in kinetic...

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
Melting and Freezing of Water
Students examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.
