The Chemistry of Energy: Endothermic and Exothermic Reactions

Slide 1 - Slide

This item has no instructions

Learning Objective
At the end of the lesson, you will be able to give examples of uses of endothermic and exothermic reactions and draw energy profiles.

Slide 2 - Slide

Introduce the learning objective and emphasize the importance of understanding endothermic and exothermic reactions in chemistry.
What do you already know about the different types of chemical reactions?

Slide 3 - Mind map

This item has no instructions

Endothermic Energy Profile
Endothermic energy profiles have a higher energy level for the products than for the reactants. The energy required for the reaction comes from the surroundings.

Slide 4 - Slide

Provide an example of an endothermic energy profile and explain how it differs from an exothermic energy profile.
Chemical Reactions
Chemical reactions involve the breaking and forming of chemical bonds, resulting in the formation of new substances with unique properties.

Slide 5 - Slide

Introduce the concept of chemical reactions and their importance in understanding the properties of different substances.
Endothermic Reactions
Endothermic reactions absorb energy from their surroundings, resulting in a decrease in temperature. Examples include photosynthesis and melting ice.

Slide 6 - Slide

Explain the concept of endothermic reactions and provide examples to help students understand the concept.
Exothermic Reactions
Exothermic reactions release energy into their surroundings, resulting in an increase in temperature. Examples include combustion and cellular respiration.

Slide 7 - Slide

Explain the concept of exothermic reactions and provide examples to help students understand the concept.
Energy Profiles
Energy profiles show the changes in energy that occur during a chemical reaction. They consist of reactants, transition states, and products.

Slide 8 - Slide

Introduce the concept of energy profiles and explain the different components that make up an energy profile.
Exothermic Energy Profile
Exothermic energy profiles have a lower energy level for the products than for the reactants. The energy released by the reaction goes into the surroundings.

Slide 9 - Slide

Provide an example of an exothermic energy profile and explain how it differs from an endothermic energy profile.
Interactive Activity
Have students draw energy profiles for endothermic and exothermic reactions, labeling the different components of the profile.

Slide 10 - Slide

Provide instructions for an interactive activity where students can apply their knowledge of energy profiles by drawing them for different reactions.
Write down 3 things you learned in this lesson.

Slide 11 - Open question

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.
Write down 2 things you want to know more about.

Slide 12 - Open question

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.
Ask 1 question about something you haven't quite understood yet.

Slide 13 - Open question

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
