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.
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
Phase Changes
In this science instructional activity, students examine the physical changes associated with the change of temperature and mixtures. The answers are included.
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
Thermochemistry
In this thermochemistry activity, students indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Students calculate...
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...
Mr. E. Science
Thermal Energy and Heat
The presentation covers Fahrenheit, Celsius, and Kelvin scales for temperature as well as conduction, convection, and radiation.

WS 7.5 Thermodynamics Concepts and Vocabulary
In this thermodynamics worksheet, students fill in the blanks with terms related to specific heat, calorimetry, phase changes, enthalpy, entropy and free energy.
Curated OER
Particle Model of Solids, Liquids, and Gases
Display the arrangement of molecules in solids, liquids, and gases. Demonstrate how the addition of heat energy results in greater molecular motion and therefore a change of phase. Give examples of heat conductors and insulators, and...
Curated OER
Heating/Cooling Curve
In this heating and cooling curve worksheet, students use a given graph of a substance being heated from a solid to a liquid and then a gas over time. They use the graph to answer eleven questions about the phases of the substance and...
Curated OER
Water Happenings
Fifth graders observe how water changes phase through a teacher-led demo. In this earth science lesson plan, 5th graders relate the demo to the water cycle. They draw and label each stage of the cycle.
Discovery Education
It's Melting!
It's a race to the finish! Which ice cube will melt the fastest? Scholars discover the effect thermal energy has on melting ice. They experiment with melting ice cubes on different materials and learn that even at a consistent...

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...
Curated OER
Phase Diagram
In this phase diagram instructional activity, students use a phase diagram to determine the substance. As the temperature is changes, students figure out the new substance and process that has occurred. This instructional activity has 2...
Curated OER
Wet Dry Ice Lab
In this wet dry ice instructional 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...

Can Boiling Make Something Freeze?
Use boiling as an avenue for freezing. Young scholars watch as liquid nitrogen removes heat from the ingredients for ice cream. As this happens, the nitrogen boils and the ice cream freezes—all in the same container. A little science magic!
Curated OER
The Same, But Different
Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...
Curated OER
Exploring Phases of Matter
Students discuss and experiment with the phases of water. In this phases of matter lesson, students recognize the different states of matter. Students measure and record changes and understand when the state changes.
Curated OER
Heat Transfer
The students construct a heating curve and explain its components. They perform calculations. They review phase changes and quantify Energy differences. They review phases of matter and their energy content.
Curated OER
Stomach Chemistry
Fifth graders compare physical and chemical changes. They perform a simulation experiment/activity that replicates what happens in the stomach as food is digested by stomach acids.
Curated OER
A Heated Discussion
Students compare the colloquial definition of temperature with the scientific definition. They, in groups, then explore the changes of water under different temperatures and calculate and compare their findings on three different...
American Chemical Society
The Water Cycle
Bring the water cycle into the classroom without the mess. Learners build a model of the water cycle using everyday materials. They observe the process of evaporation and condensation and relate their observations to the larger scale...
