1) The document discusses different concepts related to matter including defining matter as anything that has mass and occupies space. It also discusses different tools used to measure length, mass, and volume including units like meters, grams, and cubic centimeters. 2) The document provides examples of how to calculate volume of regular and irregular objects by displacement of water in a measuring cylinder. It also states that equal volumes of different substances can have different masses. 3) Measurement tools like rulers, measuring tapes, balances, and cylinders are used to measure length, mass, and volume. Common units include meters, centimeters, grams, kilograms, liters and cubic meters. Conversion factors between units are also provided.

There are many different materials-things- around us like
Anything-any object- around us is a matter
For example: Pen, cloth, fruits, cars, pencil, book…etc.
- Matter: is anything that has a mass and volume
or
it is everything that has a Mass and occupied a part of space.

To deal with matter we need to know-measure- its length, mass & volume.

Note That: Mass of ice-cream 1 > 2 > 3 is larger than mass of 2&3 why??
Because it has more matter-ice-cream- in it than in2 or 3
and also ice –cream 2= 4 because they have the same amount of ice cream in them
