1. Beach Vacation
Northwood Science 2016

2. Essential Questions What is heat?
Why do somethings get hotter than others?
How is heat transferred?

3. Performance Expectations
MS-PS3-3. Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.*
MS-PS3-4. Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.

4. Energy of motion (kinetic energy) that results in a temperature
Thermal Energy*
Energy of motion (kinetic energy) that results in a temperature
What has thermal energy on the beach?
* Review!!!
Kinetic energy (the energy of motion) can take place on a small scale, like molecules bumping into one another, or a larger scale like the rotation of a water wheel

5. To move from one area to another
Transfer
To move from one area to another
Probe- Does something need to be matter to be transferred?
Transferring energy. If you touch a hot grill the heat is transferred to you and you may be burned.

6. Heat
The transfer of thermal energy between substances at different temperatures
Heat =/= Thermal Energy. Everything has thermal energy, but there needs to be a difference in thermal energy for heat. Glass of room temp water has thermal energy but is not changing the temperature of the room it is in.

7. Temperature The average kinetic energy of the particles of a substance
Looks at all the particles in a substance and talks about their average speed.
Is a correlation. Does not mean every particle is exactly the same speed.

8. Radiation
Transfer of energy without direct contact.
Can go through space

9. Conduction Transfer of energy through direct contact.
Particles collisions
Conduction on the beach might include walking on hot sand and/or cooking food,

10. Convection
The transfer of thermal energy through the motion of particles in a fluid*
*Fluid- A gas or liquid
Convection currents are responsible for a good deal of our weather

11. Conductor A substance that allows for the transfer of energy
Emphasize the point of contact between the metal and the food.

12. Insulator
A substance that slows or stops the transfer of energy

13. An area with defined boundaries
System
An area with defined boundaries
Ex: Classroom, School, District, each have defined boundaries. Can be a system. Isolated- Cooler on the beach, Closed- Sealed Water bottle on the beach, Open- the ocean

14. Surroundings (to a system)
The area outside of the defined boundaries of the system
Beach= Surroundings
Basically anything that is not the system but has an effect or is effected by
Cooler= The System

15. Law of Conservation of Energy*
Energy is not created or destroyed only transferred and transformed.
