What is matter?
Everything around us that has mass and volume.
Give an example of measurement instruments for volume.
Flask (matraz) , pipette, density meter, beaker (vaso precipitado), etc
How can we measure volume of regular-shaped solids?
With mathematical formulas
How is mass measured?
Kilograms and grams
How is volume measured?
Litres and mililitres
T o F: Mass and weight is the same.
No. Mass is the amount of matter in an object. Weight is the measure of the force exerted on the object by gravity

Because of their density.
True or False: States of matter are always the same, they don't change.
False, they can change.
Give an example of measurement instruments for weight.
Balance, weighing scale, etc
What is mass?
The amount of matter in an object.
True or False: Particles are always still.
False, they are always moving.
