this is my work of matter and forces

1. MATTER AND FORCES
AITANA ARINERO SERNA
5º
UNIT 7

2. MATTER
MADE UP OF ATOMS (TINY PARTICIPLES)

4. PROPERTIES
VOLUME:
HOW MUCH SPACE MATTER
OCCUPIES
DENSITY:
AMOUNT OF MATTER IN A
VOLUME

5. PROPERTIES
MASS:
AMOUNT OF MATTER IN A
OBJECT
HARDNESS:
SCATH-RESISTENCE OF A SOLID

6. PROPERTIES
THERMAL CONDUCTIVITY:
ABILITY TO CONDUCTOR OR
TEANSFER HEAT
SOLUBILITY:
ABILITY OF A SUBSTANCE TO
DISOLVE IN ANOTHER
SUBSTANCE

7. TYPES
PURE SUBSTANCE:
CONSIT IN ONLY ONE TYPE OF MATTER

8. METHODS TO SEPARATE SUBSTANCES
• FILTRATION- USING A FILTER
• EVAPORATION-HEATING
• SIEVING- USING A SIEVE

9. TYPES
MIXTURES:
MADE UP OF TWO OR MORE SUBSTANCE
-HOMOGENEOUS- CANNOT
SEE INDIVIDUAL SUBSTANCES
-HETEROGENEOUS- WE CAN SEE
INDIVIDUAL SUBSTANCES

10. FORCES
FORCE IS A PUSHOR PULL THAT ACTS ON A OBJECT
CAN MAKE THINGS:
MOVE
STOP
APEED UP
SLOW DONW
CHANGE DIRCTION

11. NON-CONTACT FORCES
• MAGNETISM
FORCE OF ATTRACTION OR
REPULSION (MAGNETS ATTRACT
METAL AND MAKE COMPASSES
WORK)
• GRAVITY
ATTRATS ALL OBJECTS TOWARDS
EACH OTHER. PLANETS HAVE A
STRONGER GRAVITIONAL
FORCE.ASTRONAUTS FLOAT IN
SPACE BECAUSE IN THE SPACE
THERE IS NO GRAVITY

12. CONTACT FORCES
• FRICTION:
FORCE WHEN TWO OBJECTS RUB
AGAINST EACH OTHER. ITS ACTS
IN THE OPPOSITE DIRECTION OF
THE MOVEMENT.
• BUOYANCY:
IS THE ABILITY OF OBJECTS TO
FLOAT. IT IS AN UPWARD FORCE
ACTING IN THE OPPOSITE
DIRECTION TO GRAVITY.

13. THE END
