From Gas to Liquid to Solid
From gas to liquid condensation to solid frost, water undergoes phase changes before learners' 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...

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....

Properties of Matter
This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

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...

It's Freezing!
Here is a good worksheet 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 determine which...

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.

Melting, Freezing, and More!: Phase Transitions
Third graders listen to a talk on phase transitions and view three demonstrations. In this phases of matter lesson, 3rd graders complete a worksheet as they listen about phase transitions. They move through three demonstrations of phase...

Water and Ice
Students observe and discuss the change of water to ice and back again. In this water and ice lesson, students observe the change in temperature and what happens when water freezes and turns to ice and vice versa.

Weathering
In this weathering worksheet, students fill in 16 blanks with given terms about the types of weathering, the results of weathering and the causes of different types of weathering.

Kitchen Chemistry
Fifth graders examine both physical and chemical changes, and how to identify the difference between the two. They observe the changes that occur in butter when it is exposed to heat and cold, heat energy. In their notebooks, they write...

Water: Liquid or Solid?
First graders investigate how water can be both a liquid and a solid. They weigh popsicles and observe them as they write in their science journals. They measure the liquid as the popsicle melts and refreeze them to change them back...

Water 3: Melting and Freezing
Students understand that most substances may exist as solids, liquids, or gases depending on the temperature, pressure, and nature of that substance. This knowledge is critical to understanding that water in our world is constantly...

Glaciers and Ice Wedging
Fourth graders observe buckling sidewalks and potholes before attempting to determine how these things are caused. They freeze water filled plastic cups that have been covered. As the water freezes, the students observe what happens to...

What Changes Occur When Water Freezes?
Learners investigate the changes that occur at the molecular level when a liquid becomes a solid. They freeze water in baby jars and observe the changes that occur in the process.
