In this reactions worksheet, students state the differences between a coefficient and subscript and an exothermic and endothermic reaction. Students review the different types of reactions. This worksheet has 13 short answer questions.

In this energy worksheet, students calculate the enthalpy of chemical reactions to answer 9 problems. They determine whether the reaction is exothermic or endothermic.

In this thermochemistry activity, students answer twenty multiple choice questions about heat, enthalpy changes, thermal, mechanical and electrical energy and the laws of thermodynamics.

Students compare and contrast exothermic and endothermic reactions. In this chemistry lesson, students perform experiments to determine whether heat was released or absorbed in a reaction. They share their observations in class.

In this chemistry of ice cream activity, students investigate colligative properties and how they affect freezing points while making ice cream. Students answer short answer questions to determine if freezing is an endothermic or...

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

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

Stephen Perry invented and patented the modern rubber band in 1845. Young scientists put his discovery to work as they use rubber bands to observe entropy and enthalpy. They determine the change in free energy to figure out if it...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on the entire year's curriculum when they take this 13-page test.

Here is a terrific learning game that has pupils acting like lizards! Before the game starts, there is a class discussion on the differences between endotherms and exotherms. The main focus of the game is how each team must keep...

Students investigate the art and science of pyrotechnics.  In this chemistry and computer lesson, students learn about the chemical basis of fire and structure of fireworks.  Students then apply their knowledge in...

In this chemical reactions worksheet, students determine what is true about a system at equilibrium and give examples of macroscopic properties. Students determine minimum enthalpy and maximum entropy for reactions. This worksheet has 2...

This worksheet focuses on writing equilibrium constants. Students work to determine the direction of reactions, concentrations of different substances, and equilibrium constants.

For this equilibrium worksheet, learners predict the concentrations of solutions at equilibrium and apply Le Chatelier's principle to systems at equilibrium. This worksheet has 15 multiple choice questions.

Students explore the mesosphere and lower thermosphere globally and achieve a major improvement in our understanding of the fundamental processes governing the energetics, chemistry, dynamics, and transport of the atmospheric region....

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

What has more energy than a room full of pupils after a fire drill? This lesson plan! Explore the changes in energy during different chemical reactions, discover why some reactions feel cold and others feel hot, and tackle the concept of...

The fifth instructional activity in the six part series introduces units of energy including calories, Calories, and joules. Scholars determine the energy released when eating a snack and during activity.

Only 10 percent of an incandescent bulb's energy is used to create light; the remaining 90 percent is heat. In the unit of activities, young chemists examine energy through hands-on activities, videos, discussions, and...

In this kinetics worksheet, students define 7 terms related to the energy of reactions, they find the average reaction rate in a reaction, they sketch an energy diagram for an endothermic reaction and they compare exothermic and...

In this chemical reactions worksheet, students learn about the 5 types of chemical reactions as well as endothermic and exothermic reactions. Students are given 5 equations to balance and they identify the type of reaction for each...

For this chemical bonds learning exercise, students determine how much energy is needed to break bonds. Students classify reactions as exothermic or endothermic and identify a reaction as reversible. This learning exercise has four...

Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

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...
