 * Procedure of Investigation ||  ||
 * Materials Used- small baking pan, pure maple syrup, saucepan, large spoon, a second small baking pan, stopwatch, lab notebook, ruler, and an adult helper. ||  ||
 * Procedure: To set up the experiment- 1. Before you heat the maple syrup, make a sheet of ice by placing a thin layer of water in a baking pan and keeping it in the freezer until it is frozen solid. 2. Once the water in the baking pan is frozen, heat the maple syrup over medium heat in the saucer, stirring constantly. 3. Bring it to a boil and allow it to cook, uncovered, until it is very thick. Keep stirring to make sure it doesn't burn. 4. Set out the baking pan with the sheet of ice on the countertop. 5. On another flat area of the counter, set out the other room-temperature baking pan. 6. Use your spoon to drop one scoop/dollop of hot, thick maple syrup onto the ice or onto the room temperature baking pan. You might want to drop the scoop/dollop on the frozen baking sheet first, before the ice melts. 7. Do not touch the scoop/dollop yet, it will still be very hot! 8. Watch as the maple syrup cools. Use a stopwatch to time how long it takes for crystals to form and harden on the scoop/dollop. 9. Observe the shape and measure the length of the crystals. Use a magnifying glass to get a close look at the crystals. 10. Record your observations about how long it took for the crystals to form and how the rate of cooling affected their size in your lab notebook. 11. Repeat steps 6-9 until you have observed at least 3 scoops/dollops on each baking sheet. If your first scoop/dollop was on the frozen baking sheet, you might want to drop the next 2 scoops/dollops there, too, before the ice melts. However, if it does start to melt, simply refreeze it and you can continue with your observations on the room-temperature baking sheet.
