Energy appears in different forms, including movement (kinetic energy), heat and potential energy, and energy transformations and transfers cause change within systems (ACSSU155)

Elaborations
  • recognising that kinetic energy is the energy possessed by moving bodies
  • recognising that potential energy is stored energy, such as gravitational, chemical and elastic energy
  • investigating different forms of energy in terms of the effects they cause, such as gravitational potential causing objects to fall and heat energy transferred between materials that have a different temperature
  • recognising that heat energy is often produced as a by-product of energy transfer, such as brakes on a car and light globes
  • using flow diagrams to illustrate changes between different forms of energy
ScOT terms

Energy conversion,  Mechanical energy,  Heat

Tablet friendly (Interactive resource)

Energy chains: make electricity

Build up to six energy chains that make electricity. Select from different energy sources and choose energy converters to match. Examine the type of energy change that happens in each converter. Arrange the converters into the correct chain so that the energy can be delivered as electricity. For example, construct a chain ...

Energy chains: energy use

Select energy sources and energy converters to build energy chains to power appliances and vehicles. Examine how each energy converter in a chain loses some energy and reduces the energy available for use. For example, show that using a solar panel and an electric motor to drive a car delivers only 16% of the original energy ...

Interactive resource

Energy chains: side effects

Build energy chains that make electricity. Select different energy sources and choose energy-converters to match. Arrange converters into the correct chain so that the energy can be delivered as electricity. Examine the waste products and side effects that occur with each converter. For example, find out the environmental ...

Interactive resource

Electromagnetism: magnetic fields

Investigate the magnetic field surrounding an electromagnet. Use a compass to find the direction of the field at different places. See how field lines can be used to map the field’s strength and direction. Vary the current through an electromagnet and observe how this affects the field. For example, notice that there are ...

Interactive resource

Energy chains: power up!

Build energy chains to power appliances and vehicles. Find out about energy sources and how energy converters work. Select the energy converters that suit each source and vehicle. For example, work out how to drive a car using the energy from sunlight. This learning object is one in a series of five learning objects.

Interactive resource

Interpreting changes of state: heating

Heat ice and record the temperature and states of water at specified times. Plot a graph of temperature against time and relate sections of the graph to the states of water. Observe animations of water particles over time and explain the shape of the graph in terms of particle theory. This learning object is the first in ...

Interactive resource

Earth rotation: stargazing

Watch an animation of the Earth rotating in space showing day and night, the equinox where locations on Earth experience close to equal hours of daytime and night-time (12 hours) and views of the Earth from above the North and South Poles. Position a camera at different places on the Earth's surface to take a time-lapse ...

Interactive resource

Sound: thunderstorms

Explore the movement of light and sound from a lightning strike during a thunderstorm. Measure the time delay between seeing a lightning flash and hearing the sound of thunder. Use the time difference and speed of sound to estimate the distance to the lightning strike. For example, if thunder is heard six seconds after ...
