Reflection
Define Reflection
An object that bounces light off into a new direction.
What is heat Transfer?
The movement of heat from one place to another without changing its form.
The type of energy that comes form the sun is called
solar energy
If your city only used solar ovens what would you notice about the air
it would be a lot clearer
What are two materials we need for our solar oven
Tin foil
Pizza box
What is a Incident Ray
the incoming beam of light that strikes a surface (like a mirror) before it bounces off or bends
What are the three types of heat transfer
Conduction
Convection
Radiation
Kinetic energy
The form of energy that an object possesses due to its motion.
Most conventional ovens are pricey and need to be shipped to you but solar ovens...
Are cheap and can be made by objects in your house
The sun emits *blank* which is what gives our solar oven its heat
uv radiation
Angle of incident=
Angle of Reflection
Conduction
The transfer of heat (thermal energy) through direct contact between objects
Potential Energy
the energy of an object or system due to the body's position relative to other objects

We make sure that our tin foil is *blank* in order to make sure it reflects in a Specular way
Smooth
Define Specular reflection
This happens on smooth surfaces like mirrors. Light bounces off at the same angle it hits the surface.
Convection
the transfer of heat through fluids (liquids and gases) where warmer, less dense fluid rises, and cooler, denser fluid sinks, causing a circular movement.
The ability to do work
Solar ovens dont produce *blank* a major contributing factor to global warming
Carbon Dioxide
The role of the pizza box is to
Insulate
Define Diffuse reflection
This happens on rough surfaces. Light bounces off in many different directions.
Radiation
energy that travels through empty space in the form of electromagnetic waves
Thermal energy
Energy which results from the random movement of particles it is a type of kinetic energy this is the total amount in an object not the average.
What benefit of solar power is shown by the war in iran? (think gas prices)
Energy independence
What is happening to the air inside of the pizza box
Its in a heat cycle
