Feb 19th 2020

Tuesday, Feb. 18

Unit Essential Question: Are there planets outside our solar system that could support life? How can we locate them and determine their habitability?

Daily Essential Question: What are the conditions necessary for life?

 

Routine – Answer Yesterday’s EQ in the “Summary” section of the notes

  • Review “Conditions for Life” (Liquid Medium, Raw Materials, Energy) (8 min)
    • Liquid Medium
      • Water
    • Raw Materials
      • Oxygen, Carbon, Hydrogen, Nitrogen
    • Energy 
      • The Sun, a star, produces the vast majority
  • Write today’s EQ

 

Conditions Necessary for Life

    • Student’s take notes in SNB
      • Slide 8 – Oxygen, Carbon, Nitrogen and Hydrogen make up 97% of body
      • Slide 9 – Elements come from stars;  present throughout the universe; life needs a continuous supply
      • Slide 10 – Life on Earth based on Carbon, can build many stable molecules; trapped in rock is not useful, but it cycles out of rock and into living things.
      • Slide 11 – Look for life elsewhere, look for chemical reactions carried out by living things.

 

  • Discussion Teams 2 Selection

 

        • Discuss: Why is carbon the key element in life?
      • Slide 12 – Energy from the Sun is important for chemical reactions; used by planets to build larger molecules; animals use energy from break down molecules to fuel the building of new ones they need.
      • Slide 13 – Look for system of free flowing energy; energy from Sun and Earth’s core provide energy to system on Earth
      • Slide 14 – Energy from Sun heats planet and gravity create wind and ocean currents and tides, which circulate material. ADD – circulation of materials is very important
      • Slide 15 – Energy from core results in movement of plates
      • Slide 16 – Subduction zone plate material melts in asthenosphere, chem. react.  ADD – these are examples of large scale circulation of raw materials, if this does not happen, life won’t exist or ceases to exist (Mars is an example)
      • Slide 17 – Speculation of other energy sources
      • Slide 18 – To search for life elsewhere, look for similar conditions on other planets
      • Slide 19 – Life on other planets may look different than we know it.

 

  • Discussion Team 3 Selection

 

      • Discuss: What processes necessary for life does energy create?
