OBJECTIVE: to introduce children to the natural phenomenon of the volcano.
Forming ideas about types of volcanoes, the hazards they represent and their usefulness.
Encourage children self forming conclusions on the results of the experiment based on earlier obtained knowledge.
Nurture an interest in cognitive research, dedication, persistence, independence.
VOCABULARY: Mountain, volcano, crater, lava.
PRELIMINARY WORK: read a children's encyclopedia, "All about all" Big encyclopedia, "Levels", looking at photos, illustrations with different volcanoes. Conversations about volcanoes facts. Make a mock volcano.
MATERIAL: Illustrations of volcanoes, a model of a volcano, mix for eruption (ash, red paint, liquid soap, vinegar) .
TEACHER: Children, today we will turn into wizards. As you think about what will be discussed today? I read you the riddle and you try to guess:
I spit fire and lava
I was a dangerous giant!
Nice I have a bad reputation,
What is my name? (Volcano)
- Right, we will be talking about volcanoes. Guys, remember what is a volcano?
CHILDREN: This mountain, from which first comes smoke, then flying rocks, and then erupting lava.
TEACHER: that's Right, guys. You are already learned in the previous lessons about volcanoes. And today I'll tell you the legend about the volcano.
"A long time ago in Ancient Greece power over the volcanoes belonged to the God Hephaestus - fire. Strange it was God - ugly, lame. But he was very hardworking and strong. Hephaestus subdued the fire. He first started making jewelry, forging weapons, and then he taught this people. When the earthquake occurred, over the mountain there was smoke, fire, people said "It works Gefest". The ancient Romans gave to this God a different name - Volcano. It also means fire. And house it also became known as a volcano. "
- Here's an interesting legend about the origin of the name volcano. Now let us look at different types of volcanoes. (Children come to the computer and look on the monitor selection.)
TUTOR: Let's now go to our volcano and consider what it consists of.
See what forms a volcano, what is it like?
(It is similar to a cone, pyramid)
Right, and the top, like a funnel, called a crater.
The crater is a huge bowl with steep slopes, and at the bottom is reddish - orange hole - the mouth, going deep into the ground. The fiery liquid emerging from a volcano is called lava. To know and to understand the nature of volcanoes, it is necessary to know the structure of the Earth. People who study volcanoes are called volcanology man. These scientists are sometimes able to warn people about the impending danger and residents can leave this place and escape.
TEACHER: today we turned into wizards and try to Wake up our volcano. While he's asleep, but we Wake him up.
(The teacher prepares the mixture and carefully pouring the vinegar.)
Volcanoes began "spewing" -
From the crater the lava spewing.
On the slopes of the lava flowed
And earth, much burned.
Centuries later, evil began to cough
The volcano and the ash and the ash.
The volcano rumbles, the volcano puffing!
Now how formidable he looks!
But he started to get tired -
The fire in him began to fade.
The last time the fire smells like
And for decades fell asleep.
- Come to the end of our fun. You can draw what you remember from today's lesson.
The children's drawings will be on exhibit. In the evening, children can take their work home and talk about what they learned in the lesson.
