1 Science Starter Explain combustion.
What is the difference between nuclear fusion and nuclear fission? Why are nuclear reactions on the sun important for us on Earth? Explain how energy from the sun travels to the Earth.

2 Today’s Objective Explain how solar energy makes life possible on Earth through the process of photosythesis and differential heating

3 Today’s Exit Ticket 1) Does the ocean or land heat up faster?
2) Explain how the earth’s magnetic field protects the planet from the harmful effects of radiation. 3) What goes into plants and then what is the product after photosyntesis?

4 The Sun provides heat to the Earth
The Sun does not heat the Earth evenly The Earth also does not hold heat evenly. *Do you think that the ocean or the land will take longer to heat up in the summer?

5 The Sun provides heat to the Earth
The Sun does not heat the Earth evenly The Earth also does not hold heat evenly.

6 Is everything that the sun sends to Earth good?
Nope! The Sun emits or sends harmful radiation particles that would be bad for all living things on earth.

7 The magnetic fields repel the particles
High energy particle radiation that could endanger life on Earth is forced to drift around the Earth within two large donut-shaped regions called radiation belts. Invisible magnetic fields are the reason that particle radiation moves in this way. The magnetic fields repel the particles

8 The magnetic fields are why we have the beautiful Northern Lights!

9 Why are plants important? How does the sun make plants grow?

10 This occurs in the leaves of plants
What? PHOTOSYNTHESIS Where? Why? The purpose is to make sugar How? Uses water, sunlight, and carbon dioxide to produce oxygen and sugar. Who? Organisms that can produce their own food: Producer This occurs in the leaves of plants

11 Photosynthesis

12 Today’s Exit Ticket 1) Does the ocean or land heat up faster?
2) Explain how the earth’s magnetic field protects the planet from the harmful effects of radiation. 3) What goes into plants and then what is the product after photosyntesis?
