Daily Objectives:

1.  Explore: Energy Transfer- Energy is transferred from a source to a receiver by radiation, conduction, and convection. When energy is transferred from a source to a receiver, the quantity of energy before the transfer is equal to the quantity of energy after the transfer.

2.  Explain how light energy is transferred to chemical energy through the process of photosynthesis.

3.  Solar Energy Effects- Nuclear reactions take place in the sun producing heat and light. Only a tiny fraction of the light energy from the sun reaches Earth, providing energy to heat the Earth.

4. Identify that nuclear reactions take place in the sun, producing heat and light.

5. Explain how only a tiny fraction of light energy from the sun is transformed to heat energy on Earth.

P.EN.07.31 / P.EN.07.32 / P.EN.07.33 / P.EN.07.43  /  P.EN.07.61 /  P.EN.07.62 / P.EN.M.3/  P.EN.M.4 

Today In Class:

1.  Your goal is to create a Graphic Organizer that will demonstrate the you can: a) understand how energy types are transferred from one type of energy to another and b) show that you can think of examples of different types of energy.

*You may work with a partner who sits in your group/table or work on your own

*We will discuss this and add to it later 🙂

Directions: Choose to either draw (use 2 papers taped together) or use your laptop ( Draw; ; make a Prezi; use an online Frame of some type and fill it in….  You may choose to define any unfamiliar terms or include simple pictures by your concepts — but this is to be done only AFTER you have your G. Organizer concepts written

The Key Idea or Central Idea is…  Energy = the ability to do work and cause change

connecting concepts — connect these to your central idea

A.  Heat Transfer –

1.  radiation

2.  convection

3.  conduction

B.  Electromagnetic Spectrum – energy types (look at your notes and your diagram of the S-E spectrum)

C. Mechanical Energy or Physical Motion (list 5 examples— what can you come up with?)

D. Energy in Our Atmospheric Layers (man-made, natural)  (list 3-5 examples)

E. Electrical Energy (examples of  5+ items that generate and use electricity)

F.  Thermal Energy (list 3-5 examples of items that either produce oruse thermal energy)

G.  Chemical Energy (what are 5 examples that produce chemical reactions or undergo chemical changes to produce/.use enerfgy?)

H.  Magnetic Energy (3 + examples of items that use magnets to work – nooooooo, the answer of a “magnet” is not correct!)

I.  Nuclear Energy (3+ examples of items that use nuclear power or generate nuclear energy to work)
