Audio of class lessons in Chemistry and Biology from Logan Park High School, Dunedin New Zealand
Mendelian genetics is the process of working out probability using punnett squares. We look at where alleles come from and what they do and how you can predict the inheritance of them.
Moles are counting numbers. Lots of chemistry happens in solutions so here we look at measuring and expressing how much substance is dissolved in a solute giving concentration.
How to relate emirical formula to molecluar formula and why
Analysis of compounds gives Percentage composition. So we look at percentage composition and then how to calculate the simplest ratio of elements.
The third class on quantitative chemistry. Analysing the analysis of the reaction between Magnesium and oxygen. Based on an experiment. Unpacking quantitative chemistry some more.
More on the mole and the importance of mole ratios - stoichiometry
Introduction to quantitative chemistry - the mole
More about DNA. DNA replication - the first pass as well as where DNA replication happens.
Introduction to DNA at Year 13. Structure and function.
The fourth lesson on DNA. Structure and function
The end of an atomic structure unit - reviewing basic concepts and looking at intermolecular forces and molecular shapes
A high speed overview of the evolution and speciation topic for NZ Year 13 Biology
Photosynthesis is life's way of capturing solar energy. Respiration is how living things use that energy usefully. It's very complex biochemistry. This is a brief overview of each process
A brief overview about enzymes. What they are and how they work. Intended for New Zealand Year 12.
