Builder 2-Hour School Day - Take 1 š
Hereās our first Builder Plan.
It was good for our home!
Step 1: Your Character: Today imagine you are Galileo Galilei!
Step 2: Geography: Galileo was born in Pisa, Italy. He lived from 1564-1642. (Children look around Pisa on Google Maps and explore for a bit; point out The Leaning Tower of Pisa & mention settling and soft foundations)
Step 3: Galileo probably ate Italian food! (If kids are interested, look up Italian restaurants, have them choose a delicious looking meal, find a recipe for that meal, make a shopping list, and make sure ingredients come within a budget - make the recipe when it fits in your schedule)
Step 4: Time to experiment with Velocity (how fast something moves). Galileo mathematically defined velocity!
- Light a candle
- Blow it out
- Quickly light the smoke rising from the wick; the wick will re-light.
- After playing as long as kids want (slow-motion the candle relighting, taking photos, editing the experiment as they want to, etc) explain how it works (the following was an AI explanation; sorry AI worked best for what I had at the time):
The Physics: Phase Change (Solid > liquid > gas)
- Vaporization: When a candle is lit, heat melts the solid wax, which rises up the wick and is converted into a gas (vaporized paraffin).
- Extinguishing: When you blow out the candle, the wick remains hot enough for a few seconds to continue vaporizing the liquid wax, but not hot enough to cause full combustion.
- Condensation: This vaporized wax cools rapidly in the air, creating a white, visible stream of condensed microscopic wax particles and unburned soot. This cloud is a fuel aerosol, not just waste carbon
The Chemistry: Combustion Reaction
ā¢ Ignition: When a heat source (match) is placed in the smoke, it heats the vaporized wax to its ignition temperature.
ā¢ Chain Reaction: The gaseous wax reacts with oxygen, leading to a chain reaction of burning particles.
ā¢ The "Travel": Because the smoke consists of a dense, continuous column of combustible vapors, the ignition propagates down the path of least resistance to the heat sourceāthe wick.
Velocity Principles Behind the Trick:
ā¢ Because the downward velocity of the flame is greater than the upward velocity of the plume, the flame is able to reach the wick and re-ignite it.
Step 5: The Builder-Steward application: study ways to make a diy candle, and we can have a candle lit Italian dinner! (Naturally my kids turned it into a full blown experiment, testing out effects of different natural candle wicks to find what they felt worked best)
Step 6: Builder Reflections: In your Builder University Notebook, answer one of the following questions in about 3-4 sentences. What is Velocity, and what is one example of velocity? If you did this experiment again, what would you do differently? (Parent: Thank & complement the child for 2 specific parts of the written reflection, and point out one grammar technique that helps their point come across more clearly in writing).
All-in-all, Iād say it was a wonderful start to a new thinking strategy when it comes to creating my kidsā education.
