1 - Changes in stores
3 Beakers of coloured water (to demonstraight energy pathways and stores)
Round robin with various energy transfers such as water drinking bird, Bunsen, Elastic toy, Light bulb battery
2 - Conservation of energy
Extended writing looking at the video. Use compare key words
Conservation of energy rules
This lesson is develop extended writing skills. The points paragraph is to reward words that promote a comparitive piece
Pendulum to explain energy loss - A good idea to use a childs phone to build up to crushing
3- Energy and work
Cargo Plane world record
8.8 meters with estimated force of 1.3MN
Demonstration : Newton meters to drag a child across the classroom (sat in a wheelie chair)
4-Gravitational potential energy stores
Worlds Highest Sky DIVE
Mass of a man around 70kgs, and the height was 39,000 meters
Using childrens popper toys, to let them fire up and record the height in which they can reach. From there calculate the gravitational potential energy. Bring in the concept of paralax, and accuracy and precision.
5- Kinetic energy and elastic energy stores
Starter, gopro on a rocket
Just to recap on what energy transfers are happening
Fastest man on a hover board
Air cannon or something like a nerf gun. Use time gates to measure the speed, and calculate the KE
6- Energy Dissipation
WHy wont the fidget spinner last for ever?
Points paragraph to discuss dissipation and other forms of energy loss.
Hydrogen balloons - kids can film in slow motion. May build my own but powered by mini whoosh bottle.
7- Energy and Efficiency
Energy and Efficiency
The Efficiency of a bouncy ball. Introduce accuracy (recall paralax error) and repeatability (mean)
8- Electrical Appliances
Lesson is a description in how energy gets to us.
Long wire across front desk for demonstration in heat loss (lights up like a fuse wire)
THE AC DC demonstration too.
9 - Energy and power
Iphone on fire
Just a video to show students what could happen if all energy all at once entered your phone
A step to demonstrate power - students mass and gravitational energy on the step are calculated. Then a given time jwill calculate his power. (Two steps works well for the most powerful student in the class)
10- Big Question
12- Higher - Mix of equations
Lesson On mixing the equations
Touch Questions to get students thinking about mixing equations. Higher only
Mystery to solve
Nice video for energy discussions or revision
