Book 5: A Stone’s Throw

Flames from Fish Boil OverboilTo most people, Wisconsin’s Door County doesn’t go beyond the peninsula. Did you know, though, that the Door in Door County comes from the narrow water passage called Death’s Door? Grandpa Mike explains how the open waters of Lake Michigan to the east and Green Bay to the west crash into each other here. Stormy weather makes this stretch of water particularly dangerous. Seven-year-old Mallory searches in vain for a floating door in the water as the ferry makes its way to Washington Island. His twin sister Melody is more interested in islands. 

Our main focus of BioFables is on illuminating STEM principles through entertaining stories. However, we need to emphasize that STEM knowledge and, especially, applying STEM  in the real world require a balancing Humanities perspective. Science and Humanities represent the two sides of practical human learning, left-brain (analytical) and right-brain (creative).

This is why we are building several tools to help you determine the value of each BioFables book’s STEM, Humanities and Values content in selecting which BioFables books to give to your young readers:

    • Table of all STEM (Science, Technology, Engineering, Math) Knowledge Gateways, Subjects and Topics
    • Table of all Humanities Knowledge Gateways, Subjects and Topics
    • Table of Values
    • Table of STEM and Humanities learning topics by Chapter

The first table presents a summary of all the STEM  Knowledge Gateways (or branches, if you prefer), Subjects and Topics occuring in A Stone’s Throw. This will give you an overvew of the entire book’s STEM lessons that are woven into the A Stone’s Throw story.

The second and third tables provide the same information for the Humanities  and Values lessons.

The table of STEM and Humanities places the combined learning topics into the specific chapter where it occurs.

We’re in the process of updating each book’s topic reference tables. The table shows the breadth of each book’s content, identified by chapter. Subjects and topics of the middle column appear in  bold, followed by abbreviated versions of their Knowledge Gateway(s) in parentheses. The table should be helpful in discussing each book as your children progress through the chapters. Follow the links for further investigation. Child-friendly sites appear in orange.

Please be aware that subjects and topics are unique to each book, so the following outlines do not reflect a complete list of subjects and topics within any category.

Thanks for your patience as we build these resources for you.

BIOLOGY Life and living things
     Plants Food crops: Rutabaga, potatoes
Cultivated flowers: lavender
     Animals Animal habitats; bird sanctuary
     People Extremophile traitQuick healing
CHEMISTRY Substances, their structure, behavior, interactions
     Function pH: Acidic conditions
     Mix of structure and function Don’t want your liquid (non-food) to boil over? Use boiling chips!
Oil and water don’t mix – or do they?
Water density: how much salt did you add?
PHYSICS Properties and nature of matter and energy
     Mechanics Stones don’t walk on water, but they can skip
Speed up air, water movement by narrowing outlets (Bernoulli’s Principle)
     Optics How do lighthouse lights shine so far? Fresnel lenses
Light reflections on water move as you move
     Gravity What makes you fall down, not up
EARTH, SPACE SCIENCE Related to planet Earth and beyond
     Astronomy Look up to the night sky: Northern Lights; International Space Station
     Geography Continents, countries, oceans and other waters, and their features
         Locations Door County: Washington Island, Rock Island
     Geology Earth’s physical structure, substance, history, processes
          Groundwater Underground springs
   Environment  Physical, chemical and biological conditions that  impact people, animals, plants and microbes
Natural, human impact
          Habitats Preservation and restoration
          Wind Direction the wind blows makes a difference
          Seasons Day length
MATH Numbers, quantities and analysis
    Arithmetic Counting
     Estimating A way to figure out the middle of an odd shape
     Statistics Collect facts or numbers, then use different kinds of arithmetic to analyze them and explain why your idea is right or wrong
TECHNOLOGY Tools (products) and techniques using science
     Physics: Mechanics Water pumps: valuable tools for reaching underground water for above-ground use
Buoys: floating markers that show location of dangerous underwater hazards
     Physics: Optics Fresnel lenses save lives by shining farther out in the water than simple magnifying glass can reach
ENGINEERING Application of technology
     Architecture  (Physics, Math
Stavkirche (Stave Church)
     Data transmission (Physics; Earth, Space Science; Math) Some buoys do more than mark hazards: monitor weather, send information they collect to satellites and land-based receivers
     Complex systems (Physics; Earth, Space Science; Math ) The International Space Station combines lots of technology for lots of different purposes

NOTE: Tables of Humanities and Values content for A Stone’s Throw are being prepared and will  be uploaded as soon as possible.
