Introduction to Science
Is acquired through direct experience with the environment, through the senses.
Empirical
The three main natural sciences.
Physics, chemistry and biology
Everything that has mass and takes up space
Matter
The five states of aggregation:
Solid, liquid, gas, plasma and Bose-Einstein condensate.
Things that are not matter:
Sound, light, electricity, any form of energy.
Kinds of knowledge
Empirical, traditional and scientific
It aims to describe and explain how matter and energy behave, as well as interactions that produce motion, forces, temperature changes, electricity, light, or sound.
Physics
Amount of matter contained in a body or object
Mass
Which properties can describe a substance? (Classification of matter)
physical and chemical
Classifications of the elements in the periodic table...
Metals, non-metals and metalloids.
Accumulated, transmitted and practiced by communities over time.
Traditional knowledge
It aims to study living things, their structure and function, their reproduction, their evolution and their relationship to the environment.
Biology
Mass times gravity.
Weight
You can divide the matter acording to its composition in...
Pure substances and mixtures
Difference between mixture and compound.
The mixture is only physically joined, while the compound is chemically bonded.
Process by which a physical magnitude is compared to an established unit of measure
Measurement
It studies the composition, structure, and properties of matter, as well as the changes that occur when one substance transforms into another .
Chemistry
Relationship between the mass of a body and the volume it occupies
Density
Pure substances can be divided into...
Elements and compounds.
The 4 ways to calculate concentration
Mass-mass concentration, Mass-volume concentration, Volume-volume concentration, Parts per million
The five stages of the scientific method
They arise from the integration of the basic natural sciences.
Interdisciplinary sciences.
What happens when an object that is thrown into a lake has the same density as the water.
It's suspended.
Say at least 5 physical separation methods
Filtration, decanting, sieving, magnetic separation, evaporation, distillation, centrifugation, chromatography, etc.
The common names of groups 1, 2, 17 and 18 of the periodic table.
Alkali metals, Alkaline-earth metals, halogens, noble gases.
