### Meet the BFFs: four fundamental forces

We all know something about gravity, but what about the other fundamental forces of physics? Explore the properties of two familiar forces experienced in daily life, and of two less familiar ones. How do they interact, and what keeps everything from falling apart? This video was Kate Dent's entry into the 2013 Sleek Geeks ...

### Optics and images: plane mirrors

Position an object and a flat mirror to reflect light rays and produce images. Predict the size and position of the reflection produced. This learning object is the first in a series of three objects that progressively increase in difficulty. The series is also packaged as a combined learning object.

### A sweet illusion

See how passing shoppers are tricked by an illusion involving light and curved mirrors. Find out how curved reflectors focus light energy to a central point.

### Optics and images: plane mirrors [ESL]

Position an object and a flat mirror to reflect light rays and produce images. Predict the size and position of the reflection produced. This learning object is the first in a series of three objects that progressively increase in difficulty.

### Optics and images: curved mirrors [ESL]

Position lenses and mirrors to change the direction of light rays and produce images. Predict the properties of a reflection produced by a mirror according to its shape: flat, concave or convex. Explore how the distance of an object from a mirror affects the image produced. This learning object is the second in a series ...

### Optics and images: lenses [ESL]

Position lenses to change the direction of light rays and produce images. Predict the properties of an image produced by a lens according to its shape: concave or convex. Position a lens to produce a magnified image of an object. Explore how the curvature of a lens affects focal length and images produced. Produce real ...

### Light and reflection: light rays

Investigate whether light rays always travel in straight lines. Rotate circular walls, each of which has a single opening. Position the walls so that light from a central bulb can be seen by a person outside the walls. Make shadows by placing a range of objects between a light source and a screen. Position shapes to make ...

### Light and reflection: using mirrors

Change the direction of a light beam using a mirror. Light the way for a scribe to see inside a pyramid. Position mirrors to direct a beam of sunlight. Choose mirrors that will reflect light at a suitable angle. Find animals on a dark night. Choose a mirror that will reflect light at a suitable angle. Notice that the light ...

### Light and reflection: using mirrors: the forest

Find animals on a dark night. Position a mirror to direct a beam of light. Choose a mirror that willl reflect light at a suitable angle. Notice that the light always travels in a straight line. This learning object is one in a series of six objects. Some of the objects are also packaged as two combined learning objects.

### Circuits - upper primary

This collection of 11 digital curriculum resources is organised in three categories - types of circuits; circuit applications; and conductors and insulators. Interactive learning objects enable students to build and manipulate simple series and parallel electric circuits. Students investigate how current flows, effects ...

### Solar power

Have you ever imagined how much energy the Sun outputs every day? Listen as Dr Charles Lineweaver, from the Planetary Science Institute at ANU, describes why a solar farm based in space can capture and use more of the Sun's enormous energy potential.

### Battlefield robots on patrol

With eyesight, skills and a mission, battlefield robots are a bit like real soldiers patrolling a warzone. Find out about how and why some students have built these mobile robots, and where their innovative robot technology might be used in the future.

### Edison lights up New York

Did you know that Thomas Edison not only invented the light bulb but also a complete electrical system to light up Manhattan, New York, in the 1880s? See why inventor, electrical engineer, and businessman Thomas Edison is the person to thank for the lights and electricity we still depend on today.
