[00:00:00]Good morning everyone. My topic is water purification. Water purification is the process of removing impurities from dirty water to make it safer used. In this model, dirty water passes through different layers like stones, sand, charcoal. The stones remove large particles and remove smaller impurities and charcoal absorbs bad smell and harmful substance. Finally, thank you. Good morning everyone.

[00:00:24]Factories factories smoke and harmful gases from factories pollute the hair.

[00:00:29]Vehicles, car, bus and trucks release the smoke and gas like carbon monasting or retaining garbage release the harmful smoke. Thank you.

[00:00:41]Good morning everyone. Liquid doesn't have fixed shape. It take the shape of the container in which it is kept. If we pour water into a glass, it take the shape of the glass. If we pour it into a bottle, it take the shape of the bottle.

[00:00:59]This is because water is a liquid. Thank you. Good morning everyone. My topic is microscope. Microscope is an instrument used to see very small objects clearly.

[00:01:10]It has lenses that make tiny things look bigger. Microscope are used in science to study cells, tiny animals, and other smaller objects.

[00:01:20]microscope.

[00:01:22]It has parts like eyepiece, lenses, stage and focus. Now it is an instrument used to see very small objects clearly.

[00:01:33]Thank you.

[00:01:34]Good morning everyone. Water cycle. The water cycle is a journey of water between the earth and the atmosphere.

[00:01:42]The sun heats water in river, lake and ocean. Water change into water vapor.

[00:01:48]This process is called evaporation.

[00:01:51]Thank you.

[00:01:54]Good morning everyone. Digestive system.

[00:01:57]First one mouth. Food enters the mouth and teeth chew the food and saliva make it soft. Second one foot part. It carries food from the mouth to the stomach. Third one stomach. The stomach makes food with digestive juices. Thank you.

[00:02:16]Good morning everyone. This is my model on save earth. Earth is our only home and we all depended on it for water, air, food and shelter. Today pollution, cutting of trees and plastic waste are harming our planet. We must save water for household purpose, agriculture industries and electricity in our daily life. Planting more trees help to keep air clean and gives us oxygen. Trees provide food and shelter for animals.

[00:02:57]Thank you.

[00:03:03]Rotational motion asking circular motion.

[00:03:24]>> Good morning everyone. There topic is constellation. And there are 88th constellation recognized by the night sky. Till today the constellation of star have different shape according to the uh pattern form.

[00:03:42]Thank you.

[00:03:50]The brightest is the secondation.

[00:03:59]This is also known as the first name by the greatest of northern The polaris is the greatest star.

[00:04:27]Polaris is the greatest star. Thank you for morning everyone. Solar system. Solar system is a planet, the sun and other bodies. The sun is center of the solar system. The sun is a a big big hot star that gives up light. Thank you. Good morning everyone. My name is Koshi from 6th day. Now topic is gravitational force. Gravitational force between earth and moon. Gravity is the force of attraction of the earth. This gravitational force pull other towards the earth.

[00:05:17]Thank you.

[00:05:19]Sources of water are river, river flowing that comes rain and mountain.

[00:05:27]>> Well, water we get from underground >> many water rivers we will see.

[00:05:34]>> Pond legs and pond store water is larger or smaller.

[00:05:40]>> Thank you.

[00:05:42]>> Good morning everyone. Transparent, opaque, translutes. Transparent object allow some light to pass through them.

[00:05:50]Opaque object do not allow light to pass through them. Translutes object allow some light to pass through them. Thank you. Good morning everyone. Day and night happen because of the earth rotation on its axis. The earth take about 24 hours to complete one rotation.

[00:06:09]The side of the earth facing the sun has daytime. The side away from the sun has night time. Thank you.

[00:06:16]>> Good morning everyone. Newton's cradle.

[00:06:19]A model of cradle called Newton cradle in a diva that showed Newton law of motion especially the third law and conservation of energy. Thank you.

[00:06:32]>> Good morning everyone. Laboratory thermometer. A laboratory thermometer is an instrument used to measure the temperature of liquid in experiment. It can measure the temperature usually from about 10°C to 110°C.

[00:06:49]In this activity, we measure the temperature of hot hot milk and hot water.

[00:06:57]>> Good morning everyone. Oxygen present in the air. When we can shoot this by a candle experiment. When we cover a burning candle with a gas jar inside the jar is used up for burning. This experiment froze that oxygen is present in air and support combustion. Step 3 minutes.

[00:07:47]This was 6.4 million years ago.

[00:07:55]These are gymnastics.

[00:08:08]Yeah.

[00:08:34]Heat.

[00:08:36]Heat. Hey. Hey. Hey.
