Chapter: Plants in the surroundings
We can see plants all around us. They are different sizes like trees, shrubs, herbs, climbers, creepers etc. Most plants have two parts: root and shoot. In the shoot part of a plant many different parts are there like stem, flower, leaf, fruit etc. Each part of the plant has different functions. Plants also make their own food with the help of carbon dioxide, water, sunlight and chlorophyll which is present in their leaves; this process is called photosynthesis and thus the leaves are also called the kitchen of the plant. By this process plants make glucose and give out Oxygen gas.

CHAPTER 1MATTER
Matter is the substance which occupies space and has mass .There are three states of matter- solid , liquid , gas .Matter is composed of large numbers of molecules .Molecules is the smallest particle which can exist freely in nature by itself and it retains the properties of the substance .In solids molecules are rigid , the inter-molecular spacing is least , so solid has definite shape and size and volume .In liquids molecules are not rigid , the inter-molecular spacing is more than solid , so liquid has definite volume but not definite shape .In solids molecules are not rigid , the inter-molecular spacing is maximum , so gases has neither a definite shape nor a definite volume .
Question and answer
Write t for true and f for false
1) The molecules of each substance are identical . ( F )
2)The inter molecular forces are effective at all distances between the two molecules. ( F )
3) The molecules in a substance are in random motion . ( T )
4) In a gas the molecules can move anywhere in space . ( T )

Math
Comparing Number
IN order to compare two numbers, follow the rule
RULE 1. If the two numbers have different number of digits, the number with larger number of digits is greater.
Example: 475 have larger number of digit as compared to 97.
Then we write 475>97.
Rule 2. If the two numbers have equal numbers of digits, then we follow the steps.
Step 1: compare the digits at the leftmost places in both the numbers.
Then the number with larger digit will be greater than the number with smaller digit.
Example: 327 is greater than 139
Because here 3>1

Anything that has weight and occupies space is called matter. Matter has mass and occupies space. Matter is made up of atoms and molecules. Atoms are the smallest particles of matter which may or may not have independent existence.
Properties of particles of matter
· Particles of matter have space in between them .
· Particles of matter are in a continuous state of motion. Particles, as they have kinetic energy, are continuously moving. This kind of movement is zigzag or random. This movement goes up on heating.
· Particles of matter attract each other:
· Particles of matter attract each other with force, this force could be inter-atomic, inter molecular.
Question and answer
Q.1) Define matter .
Answer-
Anything that has mass and occupies space is called matter.
Q.2) What is the difference between mass and weight.
Answer-
Mass is the quantity of matter and weight is the force which which the earth pulls a body toward itself. The mass of a body does not change but its weight changes from place to place.
Q.3)If an object weighs 6 Newton on earth what will be its weight on moon. What will be the change in its mass?
Answer –
Weight of a body on moon = 1/6th of its weight on Earth = 1/6 of 6N = 1N on moon mass of a body does not change with change in gravity. So mass of a body will remain the same on moon.

Chapter - Structure of atom
What is Atomic Structure?
The atomic structure of an element refers to the constitution of its nucleus and the arrangement of the electrons around it. Primarily, the atomic structure of matter is made up of protons, electrons, and neutrons.
The protons and neutrons make up the nucleus of the atom, which is surrounded by the electrons belonging to the atom. The atomic number of an element describes the total number of protons in its nucleus.
Neutral atoms have equal numbers of protons and electrons
Dalton’s Atomic Theory
The English chemist John Dalton suggested the following are the postulates of his theory:
· Every matter is made up of atoms.
· Atoms are indivisible.
· Specific elements have only one type of atoms in them.
· Each atom has its own constant mass that varies from element to element.
· Atoms undergo rearrangement during a chemical reaction.
· Atoms can neither be created nor be destroyed but can be transformed from one form to another.
Question 1.
Fill in the blanks.
(a) Dalton said that atoms could not be divided
(b) An ion which has a positive charge is called a cation
(c) The outermost shell of an atom is known as valence shell
(d) The nucleus of an atom is very hard and dense.
(e) Neutrons are neutral particles having a mass equal to that of protons.
(f) Isotopes are the atoms of an element having the same atomic number but a different mass number.
Question 2.
Write ‘true’ or ‘false’ for the following statements:
(a) An atom, on the whole, has a positive charge.
False
(b) The maximum number of electrons in the first shell can be 8.
False
(c) The central pad of the atom is called nucleus.
True.

(a) Evaporation takes place at all temperature.
(b) Freezing process is the just reverse of melting.
(c) Sublimation is a process that involves the direct conversion of a solid into its vapour on heating.
(d) The temperature at which a solid convert into a liquid is called it’s melting point.
(e) The smallest unit of matter that exists freely in nature is called molecule.
(f) Molecules of a substance are always in a state of motion and so they possess kinetic energy.
(g) Intermolecular space is maximum in gases less in liquids and the least in solids.
(h) The intermolecular force of attraction is maximum in solids, less in liquids and the least in gases.
