1. Start by weighing an empty measuring cup. Then pour half a liter (500 cm3) of water into it and weigh the measuring cup with the water. The weight of half a liter of water will be equal to the difference in weight of the measuring cup with and without water.
2. Divide the weight of the water (in g) by its volume of 500 cm3. Record the result as: "Density of fresh (drinking) water: __ g/cm3."
3. Lower a raw egg into the measuring cup with fresh (drinking) water. Based on the results of the experiment, compare the density of the egg and the density of fresh (drinking) water. Record 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."

1. Вначале взвешиваем пустую мерную чашку. Затем наливаем в неё поллитра (500 см3) воды и снова взвешиваем мерную чашку с водой. Вес поллитра воды будет равен разнице веса мерной чашки с водой и без неё.2. Делим массу воды (в граммах) на её объём 500 см3. Записываем результат: "Плотность пресной (питьевой) воды: __ г/см3".
3. Опускаем сырое яйцо в мерную чашку с пресной (питьевой) водой. Основываясь на результатах эксперимента, сравниваем плотность яйца и плотность пресной (питьевой) воды. Записываем...
