Организационный момент Good morning, everybody. Today we will study chemistry using our English language. Good luck with your lesson. Let's start our lesson right now. Погружение в тему Учитель показывает изделия из алюминия, просит посмотреть на слайд, задает вопросы и читает стихотворение. What chemical element did D.I. Mendeleev call the metal of the future? What element is it talking about? I am an irreplaceable metal, Very much a pilot's favorite, Lightweight, Electrically conductive, And the character is transitional. Look at these products, what metal are they made of? Do you know what the hulls of cars, planes and missiles are made of? What are electrical wires made of? Where is aluminum used? Ознакомление с темой урока, целями обучения и критериями обучения Today in the lesson you will learn about the physical and chemical properties of aluminum . -Learn how to make chemical equations of reactions -Write the equations of possible reactions. Опрос знаний учащихся по предыдущей теме. Let's start repeating the homework. You need to remember and tell briefly about alkaline and alkaline earth metals. Remember their structure and properties. Учитель раздает ученикам стикеры разного цвета и делит класс на 3 группы. 1 group. General characteristics of metals. The position in the periodic table. Obtaining metals . Общая характеристика металлов. Положение в таблице Менделеева. Получение металлов Group 2. Alkali metals and their properties. Щелочные металлы и их свойства 3rd group Alkali - earth metals and their properties Щелочно - земельные металлы и их свойства. По одному ученику из группы выходят к доске для записи уравнений химических реакций One student from the group goes to the blackboard to write down the equations of chemical reactions .
