Wayground NOTES: Energy transformations

Make kind choices today

Make sure you have your paper copy of notes (given to you by our guest teacher) while you are completing your notes. These notes are important for our activity on Monday! :)

After you complete these notes using this wayground, you will complete the "Wayground: Energy Transformations" assignment. This is for a grade. You have 2 attempts.

Multiple Choice

Which statement best describes the Law of Conservation of Energy?

• Energy can be created and destroyed.

• Energy can be transformed from one form to another, but the total amount remains the same.

• Energy can only be transferred, not transformed.

• Energy increases as it moves from one object to another.

Multiple Choice

Which type of energy transformation occurs when wood is burned to cook food, according to the diagram?
