Ingredients 1 3/4 cup warm water 1 (1/4-ounce) package active dry yeast (recommended: RapidRise) 2 teaspoons salt 4 1/2 to 5 cups bread flour 3 tablespoons olive oil‚ plus more for bowl Cornmeal‚ for pan Directions Preheat oven at 450 degrees F. Measure out 1 3/4 cups warm water (it should be pleasantly warm on your wrist). Sprinkle the yeast on top of the water and allow it to activate‚ about 10 minutes. Put the salt and 2 cups of the flour into a food processor. Pulse 5 times to blend

Lab 1 “Laboratory Techniques and Measurements” A. Water boils at 100C at sea level. If the water in this experiment did not boil at 100 C‚ what could be the reason? * We’re not at sea level; the pressure could be lower or higher. B. While heating two different samples of water at sea level‚ one boils at 102C and one boils at 99.2C. Calculate the percent error for each sample from the theoretical 100C. (show your work) * 1st Sample: 1.96% error * 2nd Sample: 0.81% error

Linear Measurements Purpose How thick is one of the hairs on your head? Could it be measured accurately with a standard inch scale? If the smallest increment on an inch scale is 1/16 inch‚ then 20 average size human hairs could fit within the space of a 1/16 inch gap. The required degree of accuracy needed is dependent on the application. If you were to build a home‚ a standard inch scale is perfect for laying out walls and locating window openings.A dial caliper is a precision measurement tool
