The Sun: Source of Energy and Life on Earth

Dive into the fascinating world of the Sun, the powerhouse of our solar system, made up of hydrogen (72%) and helium (26%). Explore how nuclear fusion transforms hydrogen into helium, releasing immense energy in the process—turning stars into giant reactors. Discover the importance of energy flow in ecosystems, the role of chloroplasts in plant life, and the biochemical processes of cellular respiration. Join us as we observe and experiment in a bottle to understand how energy impacts life, from fermentation with yeast to the production of ATP.

Presentation Transcript

  1. The Sun

  2. Source of all Energy / Lifestart @14:50  19:50 • the SUN is made up of hydrogen (72%) and helium (26%) • Temperatures and Pressure at the center of the SUN are high enough that the hydrogen atoms combine together • Hydrogen nuclei are forced together until they fuse to form a new element & energy from the nucleus is released

  3. Stars are GIANT nuclear reactorsE = mc2 • Small stars only H  He in core • Med stars (our sun): when H gets depleted He  O2 & C • Big stars: O2 & C  Ne, Na, Mg, S, Si  Ca, Fe, Ni, Cr, Cu and others after supernova spew heavy metals into space

  4. Energystart @ 19:50  25:00 from atoms in the Sun give life on Earth

  5. All organisms need energy (fuel) to survive

  6. How does one thing affect another?

  7. we will make & observe own WORLD inside a bottle (or 2…) to study energy, energy flow and other factoring effecting life in an ecosystem

  8. Why are plants green?

  9. Chloroplast

  10. Light Reaction

  11. Calvin Cycle

  12. Cellular Respiration Video 1

  13. Glycolysis glucose  2 pyruvate 6carbons 3 carbons produces 2ATP electrons go to ETC via NADH

  14. Citric Acid or Krebs Cycle produces 2ATP electrons go to ETC via NADH

  15. ETC electrons are caught by oxygen to make H2O produces 32ATP flow of H+ fuels ATP synthase

  16. Fermentation living food: yeast, bacteria, mold, fungi muscle soreness and cramps

  17. My Kombucha ((“BrokenshireBouch”))
