### Banknotes help save money on solar

Solar cells can now be made with the same polymer technology used in Australian banknotes. Existing technology using silicon solar cells is expensive and difficult. Find out about printable solar cells made from polymer or titanium dioxide, and discover the advantages of this new technology.

### Backyard Science: circulating charges

This resource, including student videos, provides opportunities for students to investigate the movement of electricity through electrical circuits. Students explore different ways to form a closed circuit to light a bulb, and classify materials as conductors or non-conductors (insulators) of electricity. Students research ...

### What on Earth?

Help an alien to understand how flowering plants are adapted to living on Earth. Watch a demonstration about plant functions such as photosynthesis. Then examine plant parts to see how they work. This learning object is the first in a series of two objects titled 'Plant life'.

### Resistors

Build electric circuits and adjust them by using resistors and transistors. Explore circuit components such as meters, switches and batteries. Measure voltages, currents and resistance and find how they are related. Connect components in different ways and investigate the outcomes. Build a light dimmer circuit including ...

### Resistors: Ohm's Law

Build a simple circuit and explore the effect of adding a resistor. Explore the relationship between voltage (V), current (I) and resistance (R). This learning object is one in a series of four objects. The series is also packaged as a combined learning object.

### Resistors: series and parallel

Combine resistors in a range of ways to give new values of electric resistance. For example, connect them in series, or in parallel, or combine both. Predict the resistance of each combination. This learning object is one in a series of four objects. The series is also packaged as a combined learning object.

### Resistors: voltage divider

Use resistors to divide the voltage from a battery. Arrange resistors to get small voltages from larger ones. Predict the voltage across any resistor in a circuit. This learning object is one in a series of four objects. The series is also packaged as a combined learning object.

### Resistors: light dimmer

Build a light dimmer circuit using resistors and a transistor. Prevent components from burning out. Investigate the operation of a transistor and a potentiometer. This learning object is one in a series of four objects. The series is also packaged as a combined learning object.

### Metal munchers: assessment

Assess your ability to make predictions and explain your observations. Protect a spaceship from metal-munching aliens by identifying metals to feed to them. Perform tests on a range of everyday materials to discover which are metals. For example, test whether wool will conduct electricity. Explain which tests are most useful ...

### The Eureka Rebellion - Teacher idea

In this Teacher idea, taught as part of a wider inquiry into revolutions, students explored the Eureka rebellion in detail and considered to what extent the events at Eureka in 1854 can be seen as ‘revolutionary’. It includes a unit of work developed and trialled by a teacher.

### 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 ...

### Using 'Metal munchers: assessment' - Teacher idea

This Teacher idea includes video footage showing how a teacher uses the interactive assessment object L7557 'Metal munchers: assessment' to test year 5-6 students' understanding of the properties of metals. It describes and provides access to the interactive digital resource used in the classroom, along with other relevant ...

### Metal munchers: assessment: teacher guide

Use this resource with 'Metal munchers: assessment' (L7557). First, see a profile of that assessment object, which gives you some helpful background information. Then follow clear guidelines on the interpretation of student input related to performing tests on a range of everyday materials to discover which are metals. ...
