Investigating Science Year 11 Yearly

Inference

A conclusion or observation one can draw from presented details

Assumption

a thing that is accepted as true or as certain to happen, without proof.

Aurora Australis

a light display in the Earth's sky; caused by solar wind.

Spontaneous Generation Theory

the theory that living organisms can rise from nonliving things. Disapproved by Louis Pasteur and Francesco Redi by showing maggots do not arise from decaying meat

1. Democritus - Indivisible particles
2. Dalton - Law or multiple proportions
3. Thomson - Cathode rays negatively charged and embedded in the nucleus
4. Rutherford - Discovery of nucleus
5. Bohr - Atomic model

Atomic model theories

Germ Theory

the theory that infectious diseases are caused by pathogens

Law of superposition

The top rock layer and its fossils is the youngest and the bottom is the oldest.

Atomic Theory

Five statements proposed by John Dalton disapproved by J.J. Thomson with discovery of electron

Bush Medicine

Plants that ATSI people observed as having medicinal purposes

Galileo

Observed the movement of Jupiters moon and the Phases of Venus leading to the theory of heliocentricity

Newton's Law of Universal Gravitation

A particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses

Flemming

Observed effect of mold on bacterial growth

Halley's Comet

The comet discovered in 1705 that repeats itself every 75 years and last appeared in 1986.

Pareidolia

Tendency to see patterns and faces in otherwise random objects or things

Panspermia: Life transported to Earth through space
Abiogenesis
Clay theory

Origins of life on earth

Snowflakes

Dependent on ratio of temperature to water saturation

Diagram

A drawing or visual representation

Physical Replicas

Often take a big scientific phenomenon and makes it a size that can be easily observed, handled, and manipulated

Mathematical Representations

Quantify what happens in physical world through formula

Analogies

Describes one phenomenon by comparing it to something different

Computer Simulations

Solve mathematical problems in a fraction of the time it takes a person

Hippocratic Corpus: Imbalance of humours
Miasma: Bad or foul air
Too small too see: Spread through particles in air

Epidemic Model Theories

Law of Conservation of Mass

In any chemical reaction the mass of the reactants is equal to the mass of the products

Antoine-Laurent Lavoisier

law of conservation of mass

Evidence of plate tectonics

Geological evidence: Currents, mapping ocean floor, rock ages, earthquakes, volcanic activity, glacial deposits

Biological evidence: Fossils, flora and fauna, ancestors of evolution

Oxygen Theory of Combustion

Concept of phlogiston, a component every flammable substance possessed

Dalton's Atomic Theory

1) elements are composed of atoms. 2) atoms of same element are identical, but differ from other elements. 3) elements can mix together 4) atoms only change when mixed with other elements

Disapproved by JJ Thomson

Newton's Second Law

The force applied to an object is proportional to the mass of the object and its acceleration

Ohm's Law

the current in a circuit equals the voltage difference divided by the resistance

Law of Conservation of Energy

Energy cannot be created or destroyed

E = mc²

energy = mass x speed of light²
