Properties of Water with a Splash of Color
Learners explore the properties of water. In this cross curriculum art and physical science lesson, students experiment with a variety of materials to demonstrate the cohesive forces and adhesion of water. Learners create a water color...
Curated OER
Heating and Cooling Curves
Students experiment with a pure substance and a phase change. In this heating and cooling curves lesson plan, students study the effects of heating and cooling a pure substance to observe a phase change. They determine both the melting...
Curated OER
Practice Final
A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Condensation
Introduce middle school science learners to condensation with this presentation. It begins with a brief explanation of the process and humidity, but does not present all of the details. Three demonstrations need to be set up ahead of...
Curated OER
Earthquakes
Students observe the melting of ice. In this phase change lesson, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.
Curated OER
Phase Change
Students compare the freezing temperature of two substances by conducting an experiment to freeze liquid ice cream. They vary the amount of salt used in the ice cubes during the freezing procedure to determine the change in the...

Changes All Around Us
Sixth graders, in groups, observe the difference between physical and chemical changes and create a collage of pictures to show the difference.
Curated OER
What Changes Occur When Ice Melts?
Learners explore the physical process of melting. They observe melting ice and answer questions related to energy transfer during phase changes.

Ice Cream
Open this instructional activity by giving a brief history of ice cream. Using liquid nitrogen to lower the temperature, preteens make their own confection. The accompanying activity sheet queries learners about freezing point, the...
PhET
States of Matter
Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...
Curated OER
Phases
In this phases activity, 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 activity has 8 problems...
Curated OER
Phase Changes
In this science instructional activity, students examine the physical changes associated with the change of temperature and mixtures. The answers are included.
It's About Time
States of Matter: Solid, Liquid, and Gas
Solid, liquid, and gas: they all matter. Scholars create an animation of the various states of matter, experiment with the temperature of water as it changes states, and observe carbon dioxide as it changes states. The lesson also...

The Energy of Evaporation
Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...
Science Friday
Sublime Sublimation
Dry ice isn't dehydrated water, and young scientists learn why in this fascinating presentation. After watching a video, they complete three different activities using dry ice. Upon completion, they discuss the scientific principle.
