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...

States of Matter
Young scholars examine the properties of solids, liquids, and gasses. In this states of matter lesson, the teacher guides students through a series of experiments to illustrate each state of matter and how matter changes from one state...
Curated OER
Physical and Chemical Changes
Students observe examples of physical changes that can take place between the three states of matter and develop common sense and intuition in distinguishing between chemical and physical changes. They observe diagrams on the board from...
Curated OER
States of Matter
Students explore the states of matter. They discuss the different phrases of matter and categorize everyday substances as solids, liquids, or gases. Students explore the relationship between the phases on an atomic level and the role of...

Physical Properties of Matter
Students examine the physical properties of matter. They identify and classify a variety of objects based on their physical properties.
Curated OER
Physical and Chemical Properties of Matter
Young scholars identify the physical and chemical properties of matter. They review the types of matter. Students list the four states of matter (Solid, Liquid, Gas and Plasma). They recognize and describe the different types of matter.
Curated OER
Chemical Changes
Fourth graders examine and identify chemical and physical changes in a variety of substances. They observe a vinegar and baking soda demonstration, and a water, laundry detergent, and Epsom salt mixture demonstration. They discuss the...
