Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical...

The heat of solution measures how much thermal energy a dissolving substance consumes or gives off. The experiment demonstrates both endothermic and exothermic reactions. Scholars dissolve several substances, measure the temperature...

How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...

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 investigate which metal is best to use as storage material in hydrogen cars. In this chemistry activity, students differentiate endothermic and exothermic reactions. They write a reflection paragraph about what they learned in...

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)...

Students observe demonstrations of exothermic and endothermic reactions and determine the changes that take place in a chemical reaction. Students observe four demonstrations showing entropy, attraction of molecules due to polarity,...

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

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...

For this thermodynamics worksheet, students calculate the change in enthalpy for several given chemical equations provided. Students specify if the reaction was endothermic or exothermic in nature.

Students investigate temperature using the TI. In this chemistry lesson, students analyze the change in temperature, as chemicals are dissolved in water. They analyze data collected using the CBL 2.

Students measure the heat of fusion of ice. In this heat of fusion lesson plan, students use a calorimeter or Styrofoam cup and thermometer to measure the change in temperature of the water in their calorimeter. This allows students to...

Students investigate activation energy through endothermic and exothermic reactions. In this activation energy lesson plan, students conduct 2 experiments, one is an endothermic reaction and the other is an exothermic reaction. Students...

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...

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach...

Students investigate energy involved for bonds to form and break. In this thermodynamics lesson plan, students experiment with chemical reactions to observe endothermic and exothermic reactions, they explore entropy and the effects of...

Students conduct an experiment to determine what happens to heat energy during a chemical reaction. They examine an endothermic reaction by observing a chemical reactions.

Some chemical reactions produce heat, but what is really going on? Lesson focuses on the concept of energy changes, both exothermic and endothermic. Scholars perform multiple experiments, hands-on activities, and view videos of the...

A beautifully designed, eighteen-page chemistry tutorial awaits your learners. The main topics: enthalpy and entropy. By completing this lesson, students will be able to define these concepts, determine whether each is increasing or...

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.

Young scholars define and identify endothermic/exothermic reactions. Using a series of experiments, they construct and interpret potential energy diagrams for their reactions.

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...

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...

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...
