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

Evaporation
This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag and...

Condensation
It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

Exploring Moisture on the Outside of a Cold Cup: For Dry Environments
If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...

Physical and Chemical Change of Six White Substances
Students investigate chemical and physical changes in reactions. In this chemical and physical change lesson plan, students mix 6 different white substances with water, vinegar and iodine. They make hypotheses about each substance and...

Changing State
Students examine the changing states of water. In this solid, liquid, gas activity, students discover that water changes when heated or cooled. Students make predictions and then use the interactive whiteboard to "heat and cool" the...

Energy and Changes of State
Young scholars complete a variety of labs to help them explain how energy affects the changes in states of matter. They also be required to collect and record data, graph data, and apply interpretations of that data.

The Water Cycle
Fourth graders explore changes in water forms. In this water cycle lesson, 4th graders build a water cycle model and monitor it for 2 weeks in order to understand that water changes state as it moves through the cycle.
Curated OER
Water Supply
Fourth graders complete three activities. In this water supply lesson, 4th graders learn that water can exist in different forms and watch a demonstration of each form. Students explore the water cycle and make a water cycle using the...

Ice Cream in a Bag
Students discuss the three states of matter and how they are affected by temperature. They make ice cream in a bag while observing how temperature change affects the mixture. They discuss why some specimens froze more quickly than others...
Curated OER
Water and Ice
Students investigate how water goes from a solid to a liquid then back again. In this experimental lesson students conduct their own experiment and see how water changes form.

Water 1: Water and Ice
Students investigate water in its solid and liquid form. In this states of matter lesson, students experiment to see what happens as water goes from a solid, ice, to a liquid, water, and back again. They write about and illustrate the...

Changing States of Matter
In this recognizing how states of matter change worksheet, students use words from the word bank to fill in the missing words to describe how water changes to steam and ice and how steam and ice change to form water. Students complete 4...

Water 1: Water and Ice
Students discover the forms water can take. In this hands-on science lesson, students examine how water can change from a solid to a liquid and then back again.

Physical Changes and States of Matter- Two
Third graders explore the concept of evaporation as they observe how the water level changes in a cup that is left out. Working in groups they observe physical changes in a group of everyday items. They record the changes in shape, size,...
