The Earth and the Universe Part II

If you read my earlier blog post, The Earth and the Universe, you know that I am helping a homeschool family to cover some of the Hawai'i state standards for Science. We are trying to blend these disparate elements into a unified whole, so that it feels like one main lesson block.

Soon I will need to transition from Biology into Geology and Astronomy (Waldorf grade 6), Physics: Heat, Sound, Light (Waldorf grade 6), and Physics: Simple Machines (Waldorf grade 7). As I wrap my mind around how to present this -- through Zoom -- over the course of the next six or so weeks, I am going to put some brainstorming here. I welcome suggestions!


SC.3.4.1. Cells, Tissues, Organs, and Organ Systems: Compare distinct structures of living things that help them to survive


SC.3.8.1. Earth Materials: Describe different Earth materials (e.g., rocks, minerals, sand, soil) and explain their formation and composition

SC.3.8.2. Forces That Shape the Earth: Describe how the water cycle is related to weather and climate

Physics: Heat, Sound, Light

SC.3.6.1. Energy and Its Transformation: Define energy and explain that the sun produces energy in the form of light and heat

    discussing weather leads us perfectly into wind (physics: heat)

    EnergyWorks Student Guide (PDF)
    this keeps being released in new forms so I would recommend downloading the PDF now if you like it!

    background reading from PDF:
    Heat and Energy, pp.4-11

      "Heat Is the Motion of Molecules"
      diagram: Water Molecule

      "Molecules Vibrate, Spin, and Move"
      diagram: Solid / Liquid / Gas
      add to MLB

      "Heat Seeks Balance"

      "Movement of Heat in Fluids"
      diagram: Convection in Liquids / Convection in Gases

      "Wind is a Convection Current"
      diagram: Land Breeze / Sea Breeze
      add to MLB

      "Expansion and Contraction"
      diagram: Molecular Expansion

    by Terry Cash, et al. (WEATHER section)

      Heat from the Sun, p.135
      The World's Winds, p.138
      The World's Currents, p.139
      Water -- Warm and Cold, p.139

    practice reading a thermometer:
    Thermometer, p.12 of PDF

    I also really like Exploring Heat Transfer, pp.13-15 of PDF

    Published by the F.A. Owen Publishing Company in Dansville NY.
    Prepared by Donald Nasca and designed by Cynthia Amrine.

SC.3.6.2. Waves: Explain how things make sound through vibrations

SC.3.6.3. Waves: Explain how light traveling in a straight line changes when it reaches an object


SC.3.8.3. The Universe: Safely observe and describe the basic movements of the sun and moon

SC.3.8.4. The Universe: Describe that constellations stay the same, though they 'appear' to move across the night sky

Physics: Simple Machines

SC.3.7.1. Forces and Motion: Compare how simple machines do work to make life easier

    Last on the list! I think that moving into the Third Great Lesson -- early humans -- is the best choice here. We can go from early human understandings of lights and shadows to huge building projects like Stonehenge (recall The Story of Clocks and Calendars by Betsy Maestro) and the pyramids (recall Pyramid by David Macaulay).

    Waldorf has a lovely block in 7th grade on Mechanics and they spend an entire month on Simple Machines (Lever, Pulley, Wheel & Axle, Inclined Plane, Wedge, and Screw) doing tons of science explorations.

    175 Science Experiments to Amuse and Amaze Your Friends

    by Brenda Walpole (MOVEMENT section)
    Investigate Friction, p.104
    Friction in Water, p.104
    Reducing Friction... with Water, p.106
    Reducing Friction... with Oil and Grease, p.107
    Investigate Slopes, p.108
    Rolling Along, p.109
    Spin the Book, p.110
    Changing Direction, p.111
    Jumping Coin Trick, p.114
    Make a Water Wheel, p.125
    Make a Steam Boat, p.127

    we already read these as part of another block, but Locomotive by Brian Floca and All Aboard!: Elijah McCoy's Steam Engine by Monica Kulling would be perfect here too

This Waldorf grade 6 Physics block is often called "Sound, Light, Heat" but I've done it as Heat, Sound, Light and it worked exceptionally well. Heat travels in a different way from sound and light, and it is more intuitive so it is a good starting point. And ending with light (and the sun) is an easy transition into electromagnetism.
