Light interacts with biological materials in several different ways. This field of research is known as biophotonics. Associate Professor Rainer Künnemeyer, from the University of Waikato, is ...
Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for ...
This provides a timeline of events related to ultraviolet radiation from both a living world and a physical world perspective. 900 BC–500 AD – Ancient Greek and Roman women lighten their skin ...
In this activity, students investigate specular and diffuse reflection by looking into a dark box and shining a torch at various objects, coloured paper and a mirror. By the end of this activity ...
In this activity, students make a pinhole camera and see images formed on an internal screen. They then use a lens and see brighter and sharper images. This models the human eye. By the end of ...
In this activity, students aim spears at a model of a fish in a container of water. When they move their spears towards the fish, they miss! This activity investigates refraction. By the end of ...
Search data from NASA’s Kepler spacecraft for the dips in star light intensity caused by exoplanets – planets that orbit stars other than the Sun. As these exoplanets pass between the star and ...
Globe at Night is an international citizen science campaign to raise public awareness of the impact of light pollution by inviting citizen scientists to measure and submit their night sky ...
Loss of the Night is an international citizen science project aiming to quantify the illumination of the night sky caused by artificial light. By monitoring how bright the night sky is over time ...
The hole in the layer is a problem for all New Zealanders because it allows greater levels of potentially harmful UV rays to enter the atmosphere. These rays have been found to increase the risk ...
Join Karen Parker from Tahuna Normal Intermediate School and Greta Dromgool from the Science Learning Hub in a session which will introduce you to Vision 20/20, an exciting Participatory Science ...
In this online PD session recorded on 27 August 2015, secondary teacher Steve Chrystall talks about the Science Learning Hub’s light and sight resources and how he used them to teach year 9 and ...
By using the example of spearing a fish, Associate Professor Gordon Sanderson, an ophthalmologist from Otago University, explains the principle of refraction. Refraction is as a consequence of ...
Robert Hooke's diagrams of cork cells started a frenzy of activity that produced some beautiful first pictures of cells from all sorts of organisms. Here, Nobel prize winner, Sir Paul Nurse ...
What does 'cell theory' really mean? Plant cells and unicellular organisms had been observed in the 17th century, but another century was passing before they would be seen in animals. From about ...
This slideshow, from the webinar Vision 20/20, provides additional support for the webinar video. Use the slideshow menu for further options, including view full screen, and go here for the ...
Use this interactive graphic organiser to help highlight some common alternative conceptions about light and sight. Place each label where you think it belongs. This activity can be done ...
This interactive looks at the electromagnetic spectrum.
