Energy Storage and Transfer Concepts
Energy Stores & Transfers
Do now activity
: What do we already know
about energy stores? Discuss in pairs,
write your ideas down in your books.
GOOD PROGRESS:
•
Recall some common energy transfers
•
Describe types of energy stores
OUTSTANDING PROGRESS:
•
Describe energy before and after a change
Progress indicators
The principle of the conservation of energy:
‘Energy cannot be created or destroyed’
So what can it do?
It can be
stored
in various ways and
it can be
transferred.
Energy can be
stored
in different ways and
transferred
too.
Below are some images which represent some types of
energy stores
.
What do you think they might be?

Task
: You must work in 3’s for this experiment:
Person 1
:
Ball dropper
Person 2:
Reads the height the ball bounces back up to.
Person 3
:
The scribe – writes down the height the ball
was dropped from and the height it bounces back up to
Investigate:
The height a ball bounces back
compared to the height it was dropped from.
1.
What type of energy did the ball have before you dropped
it?
(1)
2.
What type of energy was your answer to Q1 transferred
to when the ball dropped?
(1)
3.
Did the ball ever bounce back up to it’s original height? (1)
4.
Can you explain your answer to Q3?
Hint: What energy
was wasted?
(2)
CONCLUSION
:
1.
The ball had a store of gravitational potential energy
before it was dropped.
(1)
2.
As the ball dropped, the store of gravitational potential
energy was transferred to kinetic energy.
(1)
3.
No, the ball never bounced back up to its original height. (1)
4.
Because energy has been wasted, some energy had been
transferred to the thermal energy store of the
surroundings and also transferred as sound waves.
(2)

Energy Stores & Transfers Do now activity: What do we already know about energy stores? Discuss in pairs, write your ideas down in your books.
Progress indicators GOOD PROGRESS: Recall some common energy transfers Describe types of energy stores OUTSTANDING PROGRESS: Describe energy before and after a change
The principle of the conservation of energy: Energy cannot be created or destroyed So what can it do? It can be stored in various ways and it can be transferred.
Energy can be stored in different ways and transferred too. Below are some images which represent some types of energy stores. What do you think they might be? THINK! chemical elastic potential gravitational potential kinetic thermal
Self-assessment: gravitational potential chemical thermal chemical kinetic elastic potential
There are five ways in which energy can be stored: C Th . K Gr . El Task: Finish the words and then match with the correct description from below! The type of energy that is stored within a moving object The type of energy that can be stored in a springy object if you stretch or squash it The type of energy that is stored in an object that has the potential to fall due to gravity This energy stores includes fuels, foods, or the chemicals found in batteries.

Self-assessment: This energy stores includes fuels, foods, or the chemicals found in batteries. The energy is transferred during chemical reactions. Chemical Thermal This describes the energy store a substance has because of it s temperature. Kinetic The type of energy that is stored within a moving object. Gravitational Potential Energy The type of energy that is stored in an object that has the potential to fall due to gravity.
