Introducing: Learning that sticks
We took the principle of advertisements and applied it to education. In order to make study easier and more effective, we developed a system that allows students to tap into their learning the way advertisements have been tapping into our subconscious. By using study notes which are condensed into fun memorable images and quotes, theContinue reading “Introducing: Learning that sticks”
Gibbs Free Energy
How can enthalpy and entropy be used to explain reaction spontaneity?
Punctuated equilibrium and Gradualism
Explain how punctuated equilibrium is different from the gradual process of natural selection
Standing waves in Strings
Investigate and model the behavior of standing waves on strings and/or in pipes to relate quantitatively the fundamental and harmonic frequencies of the waves that are produced to the physical characteristics (eg length, mass, tension, wave velocity) of the medium

The scientific Method
Aim: Hypothesis: Criteria for a hypothesis A hypothesis should be developed in response to previous research. It should be a testable and falsifiable statement which predicts the change of an independent variable and the result on the dependent variable followed with brief reasoning. Common scaffold’s for a hypothesis include: If [independent variable] then [depndent variable]Continue reading “The scientific Method”
Micro evolutionary changes
Analyse how an accumulation of microevolutionary changes can drive evolutionary changes and speciation over time, for example
– Evolution of the horse
– Evolution of the Platypus
Relative motion of objects in two dimensions
Relative motion of objects in two dimensions.
Analyse the relative motion of objects in two dimensions in a variety of situations, for example:
– a boat on a flowing river relative to the bank
– two moving cars
– an aeroplane in a crosswind relative to the ground
