1. Do Now What is a tide? What causes tides?
Earths tilt is how many degrees?
What is your favorite season?
When is the first day of Winter and why is it THAT specific day each year?

2. Light

3. Electromagnetic Spectrum
Electromagnetic Spectrum – the arrangement of waves according to their wavelengths and frequencies
Light travels as a wave or particle
Waves = found on Earth
Particles = photons found in space
Spectroscopy – the study of light properties based on the wavelength
Visible white light passes through a prism to produce the colors of the rainbow (ROY G BIV)

4. Types of Waves Cosmic rays (Moves the Fastest) Gamma rays X-rays
UV rays
Visible Spectrum
Infrared waves
Radio waves (Moves the Slowest)

5. How are electromagnetic energies related to the environment?
Cosmic Rays, Gamma Rays, & X-Rays
Important because each are involved in NUCLEAR RADIATION.
They all have HIGH energy
They all BREAK bonds in molecules
They all IONIZE atoms/molecules
Ultraviolet Radiation (UV)
Important because it affects the Ozone layer which protects humans from skin cancer.
The energy can break bonds and SOME molecules
THE ENERGY IS NOT AS HIGH AS Cosmic rays, Gamma rays, or X- rays

6. How are electromagnetic energies related to the environment?
Infrared Radiation
Important because if affects Greenhouse Effect and Global Warming.
The energy is MUCH LOWER than (Cosmic, Gamma, X-rays, and UV)
Only vibrates and bends atoms/bonds
Microwaves
Used for cooking and phones
Energy is very low
Causes water molecules to rotate which hits up other molecules

7. The Spectrum

8. The Sun

9. Energy from the Sun
Mostly in the form of UV, visible light, infrared energy, and cosmic rays.
Some energy is reflected back into space before reaching the Earth’s surface.
Most energy is used in the planet’s heat cycle, evaporation of water to drive/run the water & weather cycle, wind and waves
Only a small amount of energy is used for PHOTOSYNTHESIS

10. How is the energy from the Sun transferred?
Passes through the atmosphere
Absorbed by the Earth’s surface and objects (dark objects warm faster)
Dark objects reflect the energy
Eventually energy returns to space
NOTE: Higher temperature = shorter wavelength = greater emissions (release) rate of radiation.

11. NOTE Greenhouse Effect Energy
This is how much radiation is produced by surface temperature minus the amount that leaves the atmosphere.

12. The Sun and it’s relation to PHOTOSYNTHESIS
Solar energy turns into chemical energy through PHOTOSYNTEHSIS
Plants use sunlight to produce sugar through the actions of the chlorophyll
Chemical formula
6 H2O + 6CO2 → C6H12O6 + 6O2

13. Do Now Define Revolution Define Rotation
The Earth’s orbit is an ______________
The Earth’s tilt and its revolution around the sun causes _______________
Define Precession
Define Nutation

14. What reactions cause the Sun to produce Energy?

15. Fusion Some stars are produced by fusion
Fusion – when 2 small nuclei (plural for nucleus) join
RELEASES lots of energy when joined
INCREASES in temperature of the reactions
Found in STARS & SUN
MAIN POINT
Produces radiant energy used by stars
“FUSE”

16. Fission
Fission – reaction in which radioactive decay occurs by the SPLITTING of a large NUCLEUS into SMALLER pieces
Fission reactions produce energy

17. Let’s take a look

18. Foldable
Create a foldable comparing and contrasting fusion and fission.

19. Poster project Types of tides: Spring and Neap Tides
Draw/list how the earth-moon-sun are aligned
Explain/list when tides occur
Barycenter
Draw an image/visual aid of a barycenter
Explain Barycenter
Moon Phases
Draw each moon phase
Explain each moon phase, including when they occur
Eclipses
Solar and Lunar
Draw an image/visual aid of each eclipse
Explain each eclipse

21. Combustion
Combustion – the reaction in which Oxygen comes from the air and combines with a Hydrocarbon to make water and fire.

22. Magnetic Field & Radiation

23. How does the Earth’s magnetic field protect the planet from the harmful effects of radiation?
The magnetic force pulls the dangerous particles around the Earth
Radiation particles do not enter at the poles of the Earth but they enter at the magneto tail which is located in the magnetosphere

24. The magnetic field cause particles to move in ONE of THREE ways
Spiral Motion – electrons go one direction and protons go in another direction
Bounce Motion – particles reflect from one pole to another
Drift Motion – electrons go one direction and protons go in another direction
