# Unit: Energy

## Lessons:

16 lessons

### Energy stores and transfers (Part 1)

This lesson introduces energy stores and pathways and gives some real life examples.

### Energy stores and transfers (Part 2)

This lesson starts to quantify energy, using box diagrams, and explains the concept of conservation of energy

### Investigating energy transfers

This lesson introduces the Bunsen burner and uses it as a tool to investigate energy transfers

### Efficiency

This lesson summarises many of the foundational concepts about energy that have been introduced in lessons 1, 2 and 3 by investigating pendulums. It then discusses useful and wasted energy transfers and calculates efficiency from written questions and Sankey diagrams.

### Conduction

This lesson explains the process of conduction and consolidates key ideas of methods and variables by investigating the speed at which different materials conduct energy.

### Convection

This lesson explains the process of convection and explores real life examples of convection currents.

This lesson explains the process of radiation, demonstrates how different surfaces impact emission and links these ideas to reveal life examples.

### Insulation

This lesson describes insulation and applies it to everyday examples such as a thermos vacuum flask and a house.

### Mid topic review

This lesson is a revision of key ideas covered so far in the energy topic including: creating a catapult whilst identifying the energy transfers; comparing conduction, convection and radiation; and investigating different insulations.

### Power and energy

This lesson introduces power and its relationship to energy. It provides lots of opportunities to practice calculations and conversions.

### Energy in the home

This lesson explains how to convert between different time units, rearrange the power equation and then apply this to real life examples by calculating domestic energy costs.

### Energy in food

This lesson explores the energy in different foods and revises key ideas about how to run a successful investigation including: identifying variables, making predictions, writing a method, analysing results and writing a conclusion.

### Non-renewable energy resources

This lesson describes how fossil fuels are formed and the advantages and disadvantages of using these non-renewable energy resources

### Renewable energy resources

This lesson describes different renewable energy resources and the advantages and disadvantages of renewable energy resources.

### Anne Easley

This lesson focuses on a key scientist.

### End of topic review

This lesson is a revision of key ideas covered in the whole energy topic.
