A few sample questions
1. Why does ice float on water?
Answer: Ice is less dense than liquid water
Water expands when it freezes, making ice less dense than liquid water. This is why ice floats — a unique property that insulates lakes in winter.
2. What causes bread to rise when baking?
Answer: Yeast producing carbon dioxide gas
Yeast ferments sugars in the dough, producing carbon dioxide gas. These gas bubbles get trapped in the gluten network, causing the bread to rise.
3. Why does a metal spoon feel colder than a wooden spoon at the same temperature?
Answer: Metal conducts heat away from your hand faster
Metal is a much better heat conductor than wood. It pulls heat away from your warm hand more quickly, making it feel colder even though both are the same temperature.
