Some example of physical change are freezing of water, melting of wax, boiling of water, etc. |
A few examples of chemical change are digestion of food, burning of coal, rusting, etc. |
|

Chlorophyll molecules absorb blue light and some red light. The other colors are reflected resulting in the green color that we associate with plants. Plants get their energy to grow through a process called photosynthesis. Chlorophyll also helps in improving the immune system of your body. Chlorophyll cleanses, purifies, and heals most areas of the body. It helps regulate the level of blood sugar in the body as well.

Large areas used for waste disposal are called landfills. Landfill is another method to manage huge amount, of biodegradable waste. In a landfill, garbage is buried in such a way that it does not damage the environment . Garbage buried inside landfills stay here for a long time as it decomposes very slowly. After a landfill is full, it can be converted into a park. For example, Indraprastha Park in New Delhi is built on a landfill site.

From the garbage bins and dumping sites, garbage is collected by municipality workers. They use a huge garbage truck for this. The garbage is then taken to a landfill site.
A landfill site is usually made away from residential areas. The garbage often contains some useful items and some non-useful items. Items which can be recycled are separated and sent for recycling. Other items are left on the landfill site. Once the landfill site fills with garbage, it is covered with soil. It is left for at least 20 years before any construction can be allowed on the landfill site. Landfill site is ideal for making parks and playgrounds.

Earthworms are small worms which can move easily on hard and slippery surfaces. Earthworms move with help of tiny, stiff hair-like projections called bristles. Earthworms move forward by repeated contractions and relaxations of their muscles in the skin. A slimy substance secreted by the earthworm helps in its movement.

Living' means a thing which can grow, reproduce and has the cellular organisation. A living thing is also aware of its surrounding. These unique characteristics make a living thing different from non-living things.
Four defining features of life forms are:
(a) Growth: It is the permanent increase in cell number and size of the organism. It involves cell division. Dead organisms do not grow.
(b) Reproduction: The ability of an organism to produce progeny, more or less similar to itself, is called reproduction. Two main modes of reproduction found in organisms are the asexual reproduction and sexual reproduction.
(c) Metabolism : The sum total of all the chemical reactions occurring in the body of an organism is metabolism. No non-living object exhibits metabolism.
(d) Cellular organisation: The body of all living beings consists of one or many cells, therefore cell is known as the fundamental unit of life.

Temperate forest have vegetation type with a more or less continuous canopy of broad-leaved trees. Deciduous forests are found in regions of the Northern Hemisphere that have moist, warm summers and frosty winters—primarily eastern North America, eastern Asia, and western Europe. In contrast, evergreen forests—excepting boreal forests, which are covered in boreal forest—typically grow in areas with mild, nearly frost-free winters. They fall into two subcategories—broad-leaved forests and sclerophyllous forests.
