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
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...
Exploratorium
Bubble Suspension
Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity:
Carbon dioxide gas is more dense than air
Bubbles are semipermeable, allowing only carbon dioxide to diffuse...

Investigating the Climate System: Energy, A Balancing Act
Earth science explorers design an experiment to demonstrate that the albedo of a surface affects its temperature. They test to find out if moisture on the surface affects temperature. They discover whether or not concrete or asphalt heat...
Curated OER
States of Matter
By viewing this PowerPoint your students' understanding of molecular energy should increase. The properties and inter-particular forces are summarized. The logical progression of information is useful, but more data to demonstrate...
Curated OER
Local Hydrologic Cycle
Students draw the water cycle as it occurs in their community. In this water cycle instructional activity, students observe demonstrations of sublimation and infiltration. They also use photographs or their own drawings of their...
Curated OER
Sublimation
Students investigate sublimation and deposition using moth balls and toilet bowl freshener. For this sublimation lesson plan, students make a water bath and use two small beakers inside 2 larger beakers with moth balls in one and toilet...
Curated OER
States of Matter
In this matter worksheet, students read a chart that uses water to show the three most common states of matter. Students review the properties of solids. This worksheet has 2 graphic organizers and 8 fill in the blank questions.

AP Chemistry Chapter 9
In this AP Chemistry worksheet, learners apply concepts of electron configuration to accurately answer the questions provided. Students also draw Lewis structures of the given elements. Learners estimate the enthalpy of formation as well...
Curated OER
Phases
In this phases worksheet, students rank the chemical compounds by decreasing vapor pressure. Students use a phase diagram to determine if water undergoes any phase transitions during the four steps described. This worksheet has 8...
Curated OER
Wet Dry Ice Lab
In this wet dry ice activity, students read the information about dry ice and phase change. Students perform an experiment in which they observe phase changes of ice. Students answer analysis questions as it relates to the phase change...
Curated OER
Chemistry Practice
In this chemistry practice worksheet, students select the correct response to the given questions. Students apply knowledge about the states of matter, finding vapor pressure and atmospheric pressure.
