2. What is matter?
• Matter is every object around us that has mass and volume.
• Pencils are matter, humans are matter, water is matter.
This is matter

3. What is matter made of?
• Matter is made of tiny particles called atoms. The atom is the
basic unit of matter.

5. • If two atoms of the same
elements combine, it makes a
molecule.
• When different elements
combine they make a
compound.

6. Classifying matter
• All the stuff can be group into one of two categories stuff is either
matter or it is energy. Matter and energy are related to each other in
the mass energy equivalence that quick fact albert Einstein
proved in his equation we already now that is
• Matter is anything that has mass and takes up space.
• Remember that there exist three states of matter, Solid: which
molecules don’t move just vibrate and they are stick together, Liquid:
which molecules are separate but not too far and only someone's moved
freely, Gas: which molecules don’t care they move freely they move
around with no control ( it reminds me of my neighbor´s cat when he
drinks coffee jajaja it doesn't end well).

7. • Most form of matter that we found like the air we daily breath
(that is gas) gasoline so the cars can run (that is a liquid) and also
the sidewalk in which we obviously walk on (a solid) are not
chemically pure.
• In order to be a pure substance it has to need distinct properties
and a composition that doesn't vary from sample to sample.
• All the substances are either elements or compounds.
• Elements cannot be decomposed into a simpler substances.
• Compounds are substances composed of two or more elements, so
they contain two or more kinds of atoms.
• Mixtures are combinations of two or more substances in which
each substance have and retains its own chemical identity.

8. Weight, mass, and volume
• Weight is the measure of the amount of force of gravity pulling on
an object.
• Mass is the amount of matter in an object
• Volume is the measurement of the amount of space occupied by
an object.

9. Calculate Density
• Density is a measure of the mass of an object in a given volume.
• The formula to calculate density is Mass/Volume
• To calculate Mass you need to multiply Density X Volume
• To calculate Volume you need to divide Mass/Density
• Density= Mass/Volume
• Mass= Density x Volume
• Volume= Mass/Density

10. Changes in matter (what is)
• There are two types of change in matter: physical change and
chemical change

11. how they work
• As the names suggest, a physical change affects a substance's
physical properties, and a chemical change affects its chemical
properties.

13. Activity

14. •In this activity we will show you some
questions about the topic and you have to
give us the answer.
•Have fun.
