1. Weigh an empty measuring glass, pour half a liter (500 cm3) of water into it, and weigh the measuring glass with the water. The weight of half a liter of water will be equal to the difference between the weights of the measuring glass with and without water.
2. Divide the weight of the water (in grams) by its volume of 500 cm3. Record the obtained result as: "Density of fresh (drinking) water: __ g/cm3."
3. Place a raw egg into the measuring glass with fresh (drinking) water. Compare the density of the egg with the density of fresh (drinking) water based on the experiment"s results. Write the conclusion as: "The density of fresh (drinking) water is (greater/less) than the density of the egg, therefore the egg (sinks/floats) in fresh water."

Шаг 1: Взвесьте пустую мерную колбу и запишите ее массу. Затем налейте в колбу поллитра (500 см3) воды и снова взвесьте мерную колбу с водой. Масса получившейся воды будет равна разнице между массами мерной колбы с водой и без воды.Шаг 2: Разделите массу воды (в граммах) на ее объем 500 см3. Запишите полученный результат как: "Плотность пресной (питьевой) воды: __ г/см3".
Шаг 3: Положите сырое яйцо в мерную колбу с пресной (питьевой) водой. Сравните плотность яйца с плотностью пресной (питьевой) воды на основе результатов эксперимента.
