1. plant life Plants are of 3 types, herbs
Shrubs & trees .Herbs have soft
Stem , shrubs have woody & trees have main trunk. As, you know,
They make food by photosynthesis
using water,minerals,CO2&
Sunlight so they are producers..

2. plant life
PLANTS ARE LIVING things
There are two types of plants.1, Flowering plants 2, Nonflowering plants.
The roots collect water, minerals
From the soil and send
It to stem then to branch then to leaves .
Carbon – di – oxide, sunlight
Enter the leaf through stomata
And it start’s to mix, now the food is ready. Bud changes into flower Therefore, plant is a living thing.

3. stomata
Stomata
The tiny pores [holes] present in leaves are called STOMATA.Carbon-di-oxide ,sunlight enters the leaf through stomata it helps plant to breath.

4. animals
There are 3 types of animals, herbivores,carnivores & omnivores.
Rabbit & cow are herbivores it eat’s herbs.
Tiger is carnivores it eat’s meat.
Omnivores eat both.

5. earth
our EARTH
earth is 3rd planet of solar system. It is the only planet which has life .it has 4 layers crust ,mantle ,outer core & inner core.
Crust is 40 km deep.mantle has 2 layers , outer part is 6km thick & temperature =2000 degree
C. & molten rock Magma flows here . In outer core temp. is above c. it is made of nickel & liquid iron. In inner core temp. is above 7500.c .here iron crystles press into solid balls.

6. FUSE
Fuse is a safety device used in an electric circit to protect electrical equipments.

7. SNOWFLAKES
One of most beautiful object by nature is snowflake . A water
molecule consists of 2 atoms of hydrogen & 1 atom of Oxygen
, so when it crystallises, it has to form 3 or 6 sided figure. As they are formed they come down by air currents. they get collected around dust & when they become heavy they fall as SNOWFLAKES.

8. atom
Atomic energy is energy drawn from atoms. there are 2 ways of obtaining energy from atoms. 1) fusion 2) fission. In fusion 2 atoms are made to form 1 atom & thus tremendous energy is released in the form of heat.
When atom splits in 2 it is called fission.

9. why is ocean salty
On a average , 1 litre sea water contains 30g of salt . The beds of rock salt ,that are found in parts of world ,were all originally formed by evaporation of sea water millions of years ago. since it’s important for 9/10 th’s of volume of sea water to evaporate for rock salt
beds that are found were deposited in what used
to be partly enclosed seas. this evaporated
faster and the rock salt deposits were thus formed.
