Chemistry & Physics 9

Using flow charts to visualize energy transfer and where waste occurs. This leads to the idea of efficiency.

Potential to kinetic energy transfers, derivation of the kinetic energy equation and power.

A brief look at his final law of motion and how it affects the objects concerned.

How the concepts of work and energy are related with a brief introduction to gravitational potential energy.

Four equations of uniformly accelerated motion are derived from the velocity vs. time graph in a clear, concise way...I think!

We can represent the motion of an object with 3 different graphs. This podcast looks at each graph in turn and what can be determined from them.

What factors affect the maximum speed an object can fall of move through the air? This podcast answers this question.

Looks at the law and its practical application.

How we use vectors to represent forces and how this concept is applied to Newton's First Law of motion.

A closer look at friction and the coefficient of friction.

The first physics podcast of the series introduces one of the fundamental aspects of the subject: forces.

Looks at the reactivity series and how it helps us with displacement reactions and metal extraction.

A selection of common indicators for acids and bases is discussed along with a basic introduction to the pH scale.

Looks at the basic chemistry of acids and bases and what happens when the two are mixed.

This podcast looks at why, on an atomic level, elements are different from one another. It also looks at how they are organized in the Periodic Table.

How the mole is used with balanced chemical equations to determine the quantity of reactants need in a chemical reaction.

A look at chemical equations representing reactions. Focusing on how to balance these equations so that conservation of mass is obeyed.

..and this one looks at covalent bonding basics.

This video covers the basics of ionic boding between atoms.

..the continuing saga of..

Following on from the 'forensics lab' we take a look at one compound in more detail to see what is in it.

This podcast looks at changes of state and focuses of wax cooling from a liquid to a solid. The corresponding cooling curve is discussed and compared to water over the same temperature range.

Density of solids, liquids and gases is reviewed and how this information can lead us to estimate the relative particle spacing in these states of matter.

Having produced data tables and graphs using Excel, we transfer them to a Word document for inclusion in a lab report.

Processed data can be plotted with a trend lines to aid interpretation.

A spreadsheet allows us to organize and process our raw data.

This podcast focuses on how to organize raw data collected during an experiment.
