Are you looking for a quality resource on energy for your Grades 7 - 9 students? Are they having trouble understanding the use of flow diagrams to show energy transformations, how to calculate energy efficiency or the difference between gravitational and elastic potential energy?

Energy: Transformations & Calculating Efficiency - PowerPoint Notes and Interactives is a professionally created, human generated resource with engaging activities that will help your students to improve their understanding of this fundamental topic in science. It will also save you heaps of time because it requires virtually NO prep!

Energy: Transformations & Calculating Efficiency - PowerPoint Notes and Interactives includes:

1. PowerPoint notes

Fourteen beautifully presented PowerPoint slides covering the following topics:

• What is 'Energy'?
• Where does our energy come from?
• Types of energy: light, thermal, sound, electrical, nuclear, kinetic, potential
• Types of potential energy: gravitational, elastic and chemical.
• Use of flow diagrams to show energy transformations.
• Law of Conservation of Energy.
• Calculating energy efficiency (percentage of input energy transformed into useful output energy).

This PowerPoint presentation is divided into two main sections, each with a clear Learning Intention identified at the start. The content is clearly explained (without being overwhelming) and uses simple language to make it accessible to as many students as possible. It also has plenty of images to assist the visual learner, as well as a few editable questions that can facilitate good class discussion.

2. Interactive PowerPoint

This interactive PowerPoint can be shared with students and includes exercises and activities to help them review and consolidate what they have learnt about energy. It encourages 'active' learning and thinking, with students required to

use simple PowerPoint tools to:

• add text
• insert shapes
• 'drag-and-drop' movable objects
• insert pictures to create an 'energy' photo collage
• complete a fun word find
• design an energy-efficient house.

The PowerPoint ends with a checklist that students complete to assist them in identifying the skills and knowledge they have attained during the unit.

3. Answers to interactive PowerPoint (PDF)

Consists of detailed answers to all review exercises and activities in the interactive PowerPoint. This includes suggested answers for those that will obviously vary from student to student, such as the photo collage and energy-efficient house design.

4. Energy-efficient house plan (PDF)

This printable PDF is for those students who would prefer to complete their house design as a hard (paper) copy rather than in PowerPoint.

* Please note that many of the questions/tasks in this resource are also available in the form of task cards if you prefer:
