In this cartoon video , get complete knowledge about the concept of sinking and floating with help of few experiments.Teachers and homeschooling students can get few easy ideas to understand the concept of density,displacement and their relation to sinking.
Simplified lesson on Weathering & Erosion for primary grade kids. Weathering is the process where rocks are worn away or broken down into smaller pieces by wind ,water or plants etc.Erosion happens when these broken rocks and sediments are picked up & moved to another place by ice, water or wind. Water erosion and Wind erosion are two major types of erosion. Also erosion and weathering reasons can be divided into chemical and physical weathering. Children can learn differences in weathering vs. erosion and there are few suggested activities also in this tutorial
Water Cycle video for Kids.How water goes up in the sky & comes back on the earth.The water-cycle(also known as hydrologic cycle or the H2O cycle), is the continuous cycle of water on, above and below the surface of the Earth. Water cycle steps involve sun's heat causing water on the earth to evaporate and thus becoming part of atmosphere in shape of clouds and moisture .Clouds are actually condensed form of water. When these condensed particles of water meet cool air, the precipitation happens and water returns to the land.This cycle continues. They say ,no water is lost in the universe ,it only keeps changing the state. In this animated lesson,kids can very easily understand the whole water cycle process in a fun and easy way.The analogies and examples used in this video can also give inspiration for certain school science projects on water cycle topic.
Have you ever visited a library or a large book shop?There are thousands of books related different topics. Have you realized that these books are arranged under some titles like story books,cooking books,study books for different grades etc. Do you know why this is done? This is done to help the reader or students to sort out the books in an easy manner.All books related to one subject or class are put in one section.This is called classification.Scientists have done the same thing for classifying living organisms.
The function of the circulatory system in human body is to help in transportation of materials throughout the body.It transports oxygen,nutrient and water to all the cells of your body.Most of the nutrients in your body moves through blood, circulatory system has the organs which help in pushing blood in all parts of our body.Heart is one of the important organs of the circulatory system. Heart & blood circulation system video for Kids.Blood Circulation in human body.Explanation of Circulatory & Cardiovascular system.Educational Videos for Kids
Children would remember the earth's atmospheric layers and the inner structure of next time whenever they eat pizza,egg or burger. The earth's atmosphere is divided into five layers.The order is as follows: Troposphere,Stratosphere,Mesosphere, Thermosphere and Exosphere.The layers of the atmosphere are thicker at the bottom and they go thinner as we move up.Air pressure and intensity decreases with the altitude in the earth's atmosphere. The inner structure of the earth is like an onion or an egg,having several layers.The outer shell is known as crust,where all plantation grows.The next layer is mantle,it is made of solid rocks but it behaves like a thick liquid.Next layer is called the core, it is made of solid iron and nickel. Temperature in the core is believed to be 5000 degree Celsius.Despite so much heat, iron is in solid form in the core because of massive pressure.
With help of this educational video, kids can understand all about the different phases/changes of the matter.It removes the confusion between states of matter and phases of matter.We need to keep in mind that matter is everything around us.Like explained in states of matter video,matter is anything made of atoms and molecules and matter is anything that has mass and takes up space. If you don't understand mass, think it as the amount of stuff in an object.Objects keep changing due to heat and pressure e.g.water can move in different phases like it changes to ice on freezing & ice can change back to water through heating due to evaporation.Similarly condensation,melting are also different phases of matter
This educative video explains the difference between Force,Work & Energy .Energy is ability to do work whereas work is defined as transfer of energy from one object to another , it is especially said in order to make the 2nd object move in a certain direction.Meaning of force can be stated in following words : A force is a push or pull effect upon an object resulting from its interaction with other object.

In this animated video, children can learn about different types of pollution,causes and facts about various types of pollution as well as ways to prevent and control the environment pollution. We can define pollution as contamination or spoiling of air,soil and water by discharging harmful materials in them. This happens due to various reasons, most of which are in control of humans.Re-cycle ,Reduce and Reuse are 3 Rs suggested by environmentalists to prevent further damage to our environment.
We have all read in school that matter is everything around us. It is anything made of atoms and molecules and matter is anything that has mass and takes up space. If you don't understand mass, think it as the amount of stuff in an object.Matter can exist in 4 different states e.g. solid,liquid,gas and plasma. All the states depend upon the distance among molecules/atoms present in the material. Atoms are closest when matter is in solid state whereas in state of gas ,atoms are further away from each other as compared to liquids and solids.Changing temperature like heating can change the state of the matter. Objects keep changing their states due to heat and pressure e.g.water can move in different phases like it changes to ice on freezing & ice can change back to water through heating due to evaporation.
Germs are everywhere.They are invisible to eyes.They are so tiny that they can be seen only under microscope.There are are good germs as well as bad germs .Bad germs spread diseases. Germs can be divided into two categories- Viruses and Bacteria.Some bad bacteria cause diseases like sore throat,pneumonia etc.Some bacteria is good also e.g. certain kind of bacteria in our intestines help our body to digest the food easily. Viruses can also cause diseases like flu,measles,chickenpox etc.The list is really long.Viruses are present everywhere so washing hands on regular intervals becomes important to avoid infections or attack by viruses.
What is Soil & how many types of soil is out there? Meaning and definition -Soil is a thin upper layer of material on the Earth's surface where plants have their roots. It is made over a long period of time with weathered rocks and decayed plants and animals.A scientist who studies the soil is known as pedologist. There are three (3) major types of soil -Sandy,Clay and Loam . As for as soil profile is concerned, soil is made of different layers, these layers of soil are called soil horizons.Each layer has its own distinct characteristics.The upper layers are rich in organic matter,humus and other nutrients and are good for plants.The lower layers are rocky.Upper layer is called topsoil whereas lower level layers are known as subsoil and bedrock.
