Builder 2-Hour School Day - Take 1 😀
Here’s 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 • Ignition: When a heat source (match) is placed in the smoke, it heats the vaporized wax to its ignition temperature. • Chain Reaction: The gaseous wax reacts with oxygen, leading to a chain reaction of burning particles. • 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 source—the wick.
