Term 3: Energy & Genes

Energy -

1. Energy Costs

2. Energy Transfers

In this unit students will compare different types of energy and how it is transferred. They will also compare the cost of electricity and evaluate the advantages and disadvantages of different energy resources.

Genes -

1. Variation

2. Human Reproduction

This topic will help students to understand how characteristics are varied between species and how variation can help in different environmental conditions. Students will also look at the stages of the development of the foetus and the stages of the menstrual cycle.

A series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor.

Parallel Circuit

A parallel circuit has two or more paths for current to flow through. Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source.
