Having a good understanding of matter will aid you to better understand Chemistry and Physics.
Matter is defined as anything that has mass and occupy space.
From the above definition, we can conclude that matter has two main attributes, qualities or characteristics. These are:
Mass is the amount of matter you have or anything has. You may consider it to be the entire composition of anything. For instance, everything you are composed of (from the top of your hair to your toe nails, including all your internal organs) will account for your mass. For this reason, your mass would be significantly different from that of a newly born child.
Note: To accurately account for the mass of humans, we will have to wear nothing on our body. This is so because our clothes, shoes and accessories will add to our mass since each of these is considered as a separate "matter". (That is, each has its own mass and occupies space).
Mass is not the same thing as weight.
Note: You can also think of mass as the total composition of anything, both within (inside) and without (outside).
Using a cup of rice for instance, its ideal mass will attributed to all its entire composition; both within (rice) and without (cup).
Matter will always take up space no matter how small it is. This is true because some instances of matter can be microscopic (only be seen with the aid of a microscope). Viruses, bacteria and protists are examples of microscopic matter in this case.
Regardless how small a thing is (to the human eyes), they will still (always) occupy space. This is why the atmosphere is never empty; rather it's always filled with gases, bacteria, pathogens and other tiny particles.
According to scientific research, there are approximately 100 billion bacteria on the human body. Although we can't even see any of these, they still take up (occupy) spaces on our skin.
Note: A space completely void of matter is referred to as a vacuum. Vacuum environment do not exist naturally, rather they are prepared for medical and scientific reasons.
The point is:
Matter is everything around you, both the things you can see and those you can't see with your eyes. In fact, you are matter yourself. No matter how small a thing can be (even if they are microscopic and can't be seen with the naked eyes), they will still always have mass and occupy space.
Matter exists in four states. They are:

Amazing facts in Basic Science
Rasceta is the name given to the lines on your ✋ palm ✋
Goats have rectangular pupils in their eyes.
Think of the pupil as a hole located in the centre of the iris within of the eye.
Note: To get an idea of an iris; 'when one is said to have blue eyes', it's because the iris is blue

NOTABLE POINTS IN Basic Science
The eyebrow is an area of dense, delicate hair just above the eye.
Eyebrows perform two main functions:
Eyebrow modified in the form of Nike logo.
Note: Eyebrows can also be modified to enhance beauty.
All fruits have seeds.
There is nothing like a naturally occurring seedless fruit. Even banana, coconut and pineapple have all got seeds.
Weight can be defined as the force of gravity acting on an object.
If you traveled to space, you would be weightless because there isn't any force of gravity acting there. We all have weight on earth becasue the force of gravity acts here.
Weight is measured in Newton
Mass is the amount or quantity of matter (substance) contained in a body. For instance, everything you are composed of, both from within and outside will make up your mass.
Mass is constant throughout the universe. You will have the same mass on earth and moon respectively.
Mass is measured in gram or kilogram and it's quite different from weight.
Matter is anything that has mass and occupy space.
Matter can exist in four states namely:
