Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

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...

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

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...

Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

In this matter worksheet, students calculate volume and partial pressure for gases, compare liquid and vapor phases, and review the characteristics properties of gases. This worksheet has 12 multiple choice and 3 problems to solve.

High schoolers describe how molecules of the different phases of matter move according to the Kinetic Theory. In this chemistry lesson, students observe and participate in teacher demos. They give real world applications of the kinetic...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test. 

How can you describe heat of fusion in a way the class understands and relates the importance of this concept to present day issues? In this third instructional activity of the series, learners conduct an experiment, demonstrating...

Students analyze and evaluate evidence that matter is made of tiny particles. They observe a series of phenomena involving solids, liquids, and gases to make inferences about the spacing, interactions and relative kinetic energies of the...

How can you relate colligative properties of solutions to everyday situations? Pupils first discuss the concepts of density, boiling and freezing points, then demonstrate how to accurately determine the boiling and freezing point of...

If your pupils think a catalyst is a list of their cats, then this might be the lesson plan for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

Take part in a fun experiment and hold an impromptu bouncing contest with your class. Young scientists heat and cool balls before bouncing them to determine whether temperature changes affect how they bounce. The set of...

Young scholars participate in a small group read aloud of the short story, "Cerium" by Primo Levi. They answer several questions about the story and then relate the reading to a lecture on Kinetic theory. After the lecture they apply...

Students investigate the kinetic-molecular theory. For this state of matter lesson, students consider the differences of melting glaciers, melting icebergs and investigate on what happens when submerged water melts.

Students categorize items into one of the three states of matter. They participate in a demonstration in which they represent particles of matter. Finally, they complete an experiment in which they "race" top see who can make acetone...

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

Students describe the history of materials. They use the kinetic (particle) theory to explain changes of state in matter and trace the flow of heat during changes of state and chemical changes.

Students examine molecules and the changes in energy of a system.  In this energy systems instructional activity students complete a lab activity and describe changes of state.

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

Elementary school physical scientists explore kinetic mechanical energy by dropping a golf ball on different surfaces. They discuss how human made materials might react to light differently from nature made materials. This lesson plan...

In this physics worksheet, high schoolers examine some of the historical theories of physics through the completion of 11 questions.
