Icefish Blood Adaptations: Antifreeze Proteins
Ever wonder how fish survive in freezing cold water—especially Antarctic waters? Some fish have an adaptation that lowers the freezing point of their life fluids. Learners model these adaptations in two lab explorations. The first...
Curated OER
Melting and Freezing of Water
Students differentiate the three states of matter. In this chemistry lesson, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.

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...
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
Edible Transformations
Learners differentiate the different phases of matter. For this chemistry lesson, students conduct several hands-on exercises to discover how matter transforms when mixed together. They identify the different stages in the water cycle.

Putting the Ice in Hockey
Eighth grade physical science classes examine why the ice on which hockey is played is slippery. They do so by discussing phases of matter and the molecular motion in each. They read an article on a website and write out answers to...
Curated OER
How Structure Can Affect Properties Through Phase Changes
Students discuss how changing the structure of atoms and molecules can change the properties of a substance. They brainstorm and review their own examples of phase change with the help of a phase change diagram. Students describe the...

Version 001 - Quiz 1
The phase diagram tops this chemistry quiz. Junior scientists answer eight multiple-choice questions as they analyze it and make calculations regarding the heat of vaporization.
Curated OER
Earthquakes
Students observe the melting of ice. In this phase change instructional activity, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.
Curated OER
Phase Changes
In this science activity, learners examine the physical changes associated with the change of temperature and mixtures. The answers are included.

States of Matter
Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...
Curated OER
The Water Cycle--Model Simulation
Students build a model to simulate parts of the water cycle. They recognize and explain the essential elements of the water cycle.
Curated OER
11 - The Heat Is On
Students observe physical change of melting by observing substance in original state, melting substance, allowing substance to return to original temperature, determining if substance retained its original properties, and recording results.
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...
Curated OER
State Change
Eighth graders explore the physical change of matter. As a class, they discuss their favorite super hero and determine if the hero undergoes a physical or chemical change. Students examine the change of state and phase change. In groups,...
Curated OER
A Matter of State
Middle schoolers conduct science experiments to understand that particle movement changes as a substance changes from one phase to another phase. Students record observations of experiments that involve the three states of matter:...
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.
