Summary of entertainment for experimental activities “Journey to the Laboratory of Miracles”
So, I invite you to sit down on the chairs.
Chemist #2:
Tell me, please, my young wizards, what natural phenomena are associated with water?
Children:
snow, hail, rain, dew, frost, ice, clouds, fog, steam, ice drift, river flood.
Chemist #1:
Do you think we can see natural phenomena in our group that occur thanks to water? (children's assumptions)
Chemist #2:
Today we are in a magical laboratory, where we can, like real wizards, create several natural phenomena in one room.
Experiment No. 1 “Rain in a glass of water”
Chemist #1:
And what will be the first natural phenomenon we will see, you will find out if you guess the riddle.
White cotton wool floats somewhere, The closer the cotton wool is, the closer it is.
Children:
Rain and cloud.
- So, in order for it to rain, you need a cloud, right? Where can we get it? And I came up with an idea! We use regular shaving foam. (The teacher squeezes foam into glasses of water)
- Why do you think our foam doesn’t sink in water (children’s answers).
- That's right, foam is lighter than water and therefore floats on the surface.
Guys, look, we now have clouds in the bank too. How do clouds form in nature? (children's answers).
Chemist #2:
That's right, clouds are made up of water droplets that are lifted into the sky by heated air, turning into steam. Small droplets of water collected in clouds cool, become heavy and fall to the ground. It's raining! Therefore, we can say that rain is water falling from the clouds to the ground.
- We'll see how this happens now. To do this, I invite you to come to the tables.
— Take the pipettes. Fill them with colored water and drop them into a jar with a cloud (the experience is accompanied by the sound of rain).
- What's happening? (children's answers).
Conclusion:
The drop passed through the clouds because it was heavier than foam, and fell to the bottom of the jar in beautiful streams. So it rains.
Chemist #1:
My young wizards, let's try to use our “magic wand” again. Do you want to turn into “water droplets”. (children's answers).
The teacher gives the children “droplets” hats, and he puts on the “clouds” hat.
Music is playing.
Chemist #2:
Droplets flew to the ground. They jumped and played, but they got bored jumping alone. They gathered and flowed in small cheerful streams (droplets make streams). The streams met and became one river (the children joined together in one chain).
Droplets float in a big river and travel. A river flowed and fell into a big, big ocean (children form a round dance and move in a circle). The droplets swam and swam in the ocean, and then they remembered that mother cloud told them to return home. And just then the sun came out. The droplets became light and stretched upward (since children sit down, they rise, then stretch upward). They evaporated under the rays of the sun and returned to mother cloud (the children run up to the teacher). The teacher takes the “magic wand” and the children put on their caps again and turn into wizards.
