### Leitz illuminator for microscope

This Leitz illuminator provides improved contrast imaging when used with a microscope. It was manufactured by Ernst Leitz and used by Commonwealth Serum Laboratories, Victoria. It measures 31.0 cm (length) x 12.0 cm (width) x 27.5 cm (height), and it is part of the CSL Collection at Museum Victoria.

### Using 'Microscope skills' - Teacher idea

This Teacher idea is an introduction to the knowledge and skills secondary students require to work with microscopes and to the application of these skills in practical science activities. It includes a unit of work developed and trialled by a teacher.

Test the vision of four people to identify vision problems: myopia, hyperopia or presbyopia. Compare effects of corrective lenses on reading at different distances. Look at a cross-section of the eye showing focal variations linked to a vision problem. Explore how common vision problems are by doing a survey. This learning ...

### Using 'Light and vision' - Teacher idea

This Teacher idea explores the eye as a receptor of light. Students build on prior understandings of light relating to wave theory and particle theory, and move on to investigate reflection, refraction, optics and prisms. It includes a unit of work developed and trialled by a teacher.

### Optics and refraction: focal point

Look at light rays magnified by a lens. Notice how light converges after it leaves the lens. Examine how curvature and thickness of a lens affect focal length. This learning object is one in a series of three objects. The series is also packaged as a combined learning object.

### Optics and prisms

Position a prism to split white light into its component colours. Predict the seven colours that will be produced. Test whether the colours seen are affected by the prism material: glass, flint glass or diamond. Explore whether filters add or remove colours from the spectrum. This learning object is a combination of three ...

### Optics and prisms: coloured light

Position a prism to split white light into its component colours. Explore whether filters add or remove colours from the spectrum. This learning object is one in a series of three learning objects. The series is also packaged as a combined learning object.

### Far out lenses

Look at the Moon through a simple telescope. Adjust the focal length of two convex lenses and compare the results. Explore relationships between optical variables such as focal length, position of objective lens, convexity, image inversion and lens size. This learning object is one in a series of two learning objects. The ...

### Leitz arc lamp for microscope, c1912

This is a Leitz arc lamp for use with a microscope when coloured filtration was necessary and for photomicrography when ordinary illuminators were too weak or unsuitable. It was powered by a 6-volt battery. The lamp was made by Ernst Leitz in around 1912 and was used by Commonwealth Serum Laboratories, Victoria. The lamp ...

### Microscope slides with blood smears, c1920

This item consists of microscope slides containing blood smears, prepared c1920. They are in an open storage box. The box of slides was used by Commonwealth Serum Laboratories (CSL) Limited in Parkville, Victoria. It has the appearance of a cloth-bound book with marbled paper edges, and contains enough wooden racks to store ...

### Schoolgirls and teacher in school laboratory, c1955

This is a black-and-white image from the original negative depicting a nun supervising a group of female school students who are carrying out chemistry experiments in a school laboratory. The girls are using microscopes and other scientific equipment. This image is part of the Laurie Richards Collection of commercial photographs ...

### Exploring nanotechnology

Peter Binks, CEO of Nanotechnology Victoria, answers the question 'How does nanotechnology work?' Discover what nanotechnology is and see several examples in action, such as scratch-resistant paint used in the car industry. Consider future applications of nanotechnology in areas such as sports, health care, clothing and cleaning.

### Using a lens to bend light

How can a water-filled plastic straw be used to decode a secret message? Watch as the Surfing Scientist demonstrates how lenses with a curved surface do curious things to light.

### Nano-engineering: science fiction or reality?

Explore the amazing field of nano-engineering. Imagine being able to construct molecular-sized machines that could do specific tasks like carrying out nano-surgery on damaged cell structures in your body. Decide for yourself what might be possible and what might just be science fiction.

### Innovation to improve underwater photography

The way light moves through water presents some challenges for underwater photographers. Watch this clip to find out how cinematographer Pawel Achtel may have solved the issues of distortion and loss of sharpness sometimes observed in underwater images. See his innovative design at work.

### What is an optical dog nose?

What do you think an 'optical dog nose' is? Watch this video to find out how this technology can be used in the real world. Can you think of some other potential applications for this technology?

### Droplet lens technology

Imagine if you could turn your smart phone into a microscope. These scientists have found a way to do just that. Watch this video to find out how easily and cheaply a high-resolution microscope can be made, and how this innovation is helping to revolutionise science and medicine all around the world.

### Zooming in

This learning object provides a ‘virtual microscope’ enabling learners to view ten successive 10 x magnifications of a gum leaf. The views reveal the internal structure of the leaf with a series of coloured graphics that mimic the zooming in action of a microscope. Brief explanatory text accompanies each graphic. The object ...

### Primary Connections: Light Shows

This comprehensive teacher resource explores the properties of light through a series of collaborative inquiry-based learning activities. Reflection, absorption and refraction of light, and consideration of how humans use light, are investigated using hands-on activities. Eight structured lessons are included, with comprehensive ...

### Light and the law of reflection: Teacher idea

In this Teacher idea, students explore how light travels and the law of reflection. They consolidate their knowledge using of a range of learning objects then explore the eye and the use of lenses. It includes a unit of work developed and trialled by a teacher.
