Energy changes

UNIT

This lesson, students will define exothermic and endothermic reactions and give examples of each.

Exothermic and endothermic reactions

This lesson, students will identify variables affecting the temperature change in a reaction, then process data and display these appropriately.

Required Practical: Temperature change (Part 1)

This lesson, students will draw conclusions and explain the changes in temperature in experiments. Students will then evaluate the equipment and data and make suggestions for improvements.

Required Practical: Temperature change (Part 2)

This lesson, students will write a method to test a given hypothesis.

Writing a method to test a hypothesis

This lesson, students will draw energy level diagrams for exothermic and endothermic reactions. Students will identify activation energy and overall energy change in energy diagrams. We will also explain why reactions are endothermic or exothermic in terms of bond breaking and bond making.

Energy level diagrams

This lesson, students will calculate bond energy values and use them to predict whether a reaction will be exothermic or endothermic. Students will relate bond energies to the correct part of energy level diagrams.


Calculating bond energies

In this lesson, students will describe how cells and batteries can be made and how the voltage can vary. Students will describe how a fuel cell works and write half equations for the electrode reactions in a fuel cell. We will also evaluate the use of hydrogen fuel cells in comparison to rechargeable cells and batteries.


Fuel cells

This lesson will review the Combined Science content of this unit.

Review combined

This lesson will review the GCSE Chemistry content of this unit.

Review chemistry

This lesson will look at the lives and work of Roger Billings and Saiful Islam.
