Now, moving on to Explanation. let’s open the text on page 78 and listen to me.

The skin cover our body. It consist of 3 layers: Epidermis, Dermis and Hypodermis. 

Epidermis – the outermost layer of the skin. Он состоит из мервых клеток и защищает организм от болезнетворных микроорганизмов. Кроме того, он удерживает влагу внутри тела. 

• Consider the skin on the palm and back. Describe the skin and compare. Рассмотрите кожу на ладони и тыльной стороне. Опишите ее и сравните. 
• Is lines on the fingers from different people differ or the same? Let’s check! Борозды и линии на пальцах у всех людей разные. Давайте это проверим. (учитель дает скотч всем ребятам, они делают отпечаток с большого пальца и сравнивают в парах) 
• Why do people make fingerprints? Для чего люди делают отпечатки пальцев?
• What happens if you damage the skin? Что произойдет, если поцарапать кожу?
• Если снять с яблока кожуру и оставить на некоторое время, каким оно станет?
• Epidermis contains melanin pigment. Эпидермис содержит пигмент меланин, который защищает наш организм от ультрафиолетовых лучей. 
• Stand in line depending on skin color from light to dark. Давайте станем в ряд в зависимости от цвета кожи, от самого светлого до темного. (ученики читают и переводят факт стр 78)

Dermis – thick layer of skin under epidermis. Receptors, sebaceous glands, sweat glands, blood vessels are located in the Dermis. 

• Как называют врача, который лечи кожные заболевания?
• I need to one volunteer. Who want help me? Close your eyes and say what do you fill. (ученик должен определить вес, форму, размер предмета, теплоту рук и силу рукопожатия)

Hypodermis – the deepest part of the skin which contains fat cells.
