Energy Transformations

 

Kia ora, bonjour, Hola, Guten Tag, Konnichiwa, Nǐn hǎo, Salve and Zdravstvuyte 

Today in Science we are looking at Energy Transformations,

When energy is passed or changed from one type to another  

The eight types of energy

1. Kinetic -  anything that has to do with movement 

2. Chemical potential - is from food and fuel with changes to kinetic  

3. Heat - anything that has the stuff to do with temperatures

4. Light- Waves that are reflected that you can see 

5. Gravitational - Effect of gravity pushing down 

6. Elastic Potential - anything we can stretch 

7. Electrical- anything that uses the power 

8. Sound- energy that you can hear 

Marshmallow Cannons:

1. Cut the base out of a cup

2. Stretch a balloon

3. Cut ½ was down the neck of the balloon 

4. Put a balloon over the cup and enjoy your homemade cannon

What energy did it use?

Sound

Elastic potential 

Kinetic energy

Gravitational 

Why did these energies happen?

Sound because you are pulling the balloon making sound

Elastic because you are pulling the balloon giving it, its energy

Kinetic because the object is moving across the air so it is "Moving"

Gravitational is because when it has moved across the air it can not stay there forever so it falls to the ground.
