Activity 58: Follow the Energy

Warm up: You set off a bottle rocket that has
200 J of chemical potential energy.
• What types of energy can the
chemical potential energy
transform into?
• If all of the energies that it
transformed into are equal, how
many joules should each type
have?
Activity 57 In Case You Missed It…

The Law of Conservation of Energy states that
energy cannot be created or destroyed, but
rather transformed or transferred.

The total amount of energy used in a system or
scenario never changes, instead it changes
form.
◦ If a car has 100 J at the top of a hill, it will still have
100 J at the bottom of the hill. It will just be a different
type of energy. (Potential  Kinetic/Thermal/Sound)

Word Sort

Each stack of words or phrases has one word
that encompasses the rest of them.

Each stack also has a word that does not
belong.

Put the all-encompassing word at the top and
the word that doesn’t belong to the side of your
list.


Look at your
words, the word sort that
has “release” and “absorb.”

What are some examples of where energy is
absorbed or released during a transfer or
transformation?
Activity 58: Follow the Energy

Please open your books to page D32.
Activity 58: Follow the Energy

Read the procedure with your group on page
D33.

Instead of getting 8 cards like the book says,
you are getting 12.

When you are finished, you can work on the first
analysis question.
Energy Types: Potential Energies

Chemical potential energy- energy stored in
bonds of atoms and molecules.
◦ Energy stored in food before you digest it.

Elastic potential energy- energy stored by
stretching or compressing.
◦ Energy stored in a stretched rubber band.
Energy Types: Potential Energies

Gravitational potential energy- energy stored
due to an object’s weight and height.
Energy Types: Kinetic Energies

Electric energy (current)- movement of a
charge and energy from one place to
another.
◦ Electricity through wires.

Light energy- energy transferred by rapid
movement of electromagnetic fields.
◦ Energy transferred by sunlight or X rays.

Motion (kinetic)- movement of an object
from one place to another.
Energy Types: Kinetic Energies

Sound energy- energy transferred by the
vibration of an object.
◦ Music, voices, etc.

Thermal energy- energy transferred from hot to
cold objects.
◦ Hot plate heating hot water

How do we see the Law of Conservation of
Energy in our homes?
