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...

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...

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...

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...

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...

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...

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...

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...

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...

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.

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...

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. 

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...

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

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.

Pupils identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.

Students study the properties of the frictional force between two surfaces in contact. They inspect various phenomena in nature where friction plays an important role and demonstrate

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

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this instructional activity. The material includes clear instructions for each...

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...

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...

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.

Studying levers couldn't be more exciting! Learners build their own catapults and test the results as they make adjustments to the fulcrum. They compete against other groups to create the most accurate apparatus.

Students are introduced to gases. In this science lesson plan, students demonstrate that gases are a state of matter, generate a number of gases, discover some properties of gases, compare some of the properties of different gases, and...
