What is matter?
Matter is EVERYTHING around us that takes up space (has a VOLUME) and has a MASS: air, water, rocks, and even people are examples of matter. The GENERAL TWO PROPERTIES of matter are: - The mass of an object is the amount of material that makes up the object. We measure its weight with a scale in gor Kg. A bowling ball, for example, has more mass than a beach ball. - And the volume: which is the space that the object occupies. We measure it submerging an object in water. It pushes water away and takes its place.
How to measure Mass & Volume
Different tools are used when measuring mass and volume.
Objects with the same volume don't necessarily have the same mass. Objects with the same mass also don't necessarily have the same volume.
Specific Properties
Last year, we studied some specific properties such as: colour, hardness, elasticity, strength, transparency, conductivity, taste, magnetism, and solubility... Now, we will focus on: other two important properties that are interrelated: 1. Buoyancy in the water is the ability an object has to float or
sink in liquid. It depends on density.
An object floats if its density is lower than the density of the
liquid around it. It sinks when the object´s density is higher than the liquid´s. We float more easily in the sea than in a swimming pool
because salty water is denser than fresh water.
Specific Properties
2. Buoyancy in the air is the ability an object has to float or sink in the air. It also depends on density. There are several ways that people have discovered to fly without using an engine, like hang gliders, parachutes and hot air balloons. A hang glider can fly for a long time without falling because of the large surface area of the fabric. The pilot uses air currents to stay afloat. The fabric of a parachute also has a large surface area which allows you to descend at a constant speed, as if you were only jumping from about 3 meters.
Specific Properties
3. Density is a specific property of matter, we use it to distinguish different types of matter. It is the relationship between the mass and the volume of a body. The value of density can be obtained by dividing the value of
the mass by the volume. MASS VOLUME Different materials have different densities, as shown below.

Scientific Method
The scientific method is a method of research used by scientist in which a problem is identified, data is registered, we make a hypotesis form that data and we test it through experimentation.
STEP #1: OBSERVE The first step is to make an
observation. Identify a problem or ask a question about
something that is going on. STEP #2: QUESTION The second step is to come up
with a question based on observations. Without a question,
there can be no answer. STEP #3: HYPOTHESIS In step three, make an educated guess, or
hypothesis. This is a potential answer to a
question that can be tested. To make a
hypothesis, estalish what you think is going to happen.
Scientific Method
STEP #4: EXPERIMENTIn step four, design an experiment that will test the question
you are asking and carry it out. Results
should be recorded and observations made. Sometimes multiple experiments are carried out before conclusion can be made.
STEP #5: RESULTSIn this step, the results are gathered and analyzed.
Data is often organized in a charts, graphs, diagrams,
or summaries to share the results.
STEP #6: CONCLUSIONWe need to establish whether our hypothesis as been proven or disproven. When tested several times, it can be become a law,
a theory accepted as true. Laws can still be changed
though by other experiments.
