STOMP ROCKET STATION

1.

What energies are present?

2.

Where does the KE come from?

3.

Where does the initial energy come from?

GRAVITATIONAL POTENTIAL The stored energy due to height above a reference point GPE = mgh

Maximum GPE GPE becoming KE

Minimum GPE

PULL BACK CAR

1.

What energies are present?

2.

Where did the initial energy come from?

3.

What is the pullback energy similar to? What else can you think of that bounces back?

ELASTIC POTENTIAL ENERGY The energy stored in a deformed

  • bject,

for objects that have the tendency to return to original shape

POP-UP TOY

1.

What energies are present?

2.

Where did the initial energy come from?

3.

How is this related to the previous station?

METAL IN WATER

1.

What energies are present?

2.

Where did the energy start?

3.

Where did the energy end up?

4.

Did the energy change forms at all?

THERMAL ENERGY LAB REVIEW

3 factors determine the amount of thermal energy in a substance

 Type of substance – Different materials can hold more or less

thermal energy. The more it holds, the slower its temperature changes.

 Mass of substance – More Mass = More particles holding energy  Temperature of substance

Kettle gets hot fast! – hold less thermal Water slower to heat – holds more thermal

CLAY BALL DROP

1.

What energies are present?

2.

Where did the energy come from?

3.

What happened to the clay?

WHAT IS DEFORMATION? The transfer of KE to thermal energy causes a change in shape

  • f substances (visible in soft

substances)

SOUND

Organized movement of particles – Turns to thermal energy once

  • rganization is lost

CIRCUIT

1.

What energies are present?

2.

Where did the energy start?

3.

Where did the energy end up?

4.

How did the energy travel?

CHEMICAL POTENTIAL ENERGY

The energy stored in the arrangement of atoms

ATOMS TELL YOU ABOUT MATTER BONDS TELL YOU ABOUT ENERGY NEW MOLECULES NEW FORMS OF ENERGY  THERMAL and LIGHT CHEMICAL REACTION

FORMS OF ENERGY AND WAYS TO TRANSFER ENERGY

Forms of energy

  • bserved in objects

at the stations:

 Gravitational Energy  Kinetic Energy  Thermal Energy  Elastic Energy  Chemical Energy

Ways to transfer energy:

 Mechanical Energy

(Work)

 Heat Energy (Heating)  Electrical Energy

(Electricity)

 Light Energy

(Radiation)
