In the thermal plasma spraying process, the coating material, in fine powder form, is injected into a high-temperature plasma jet. The powder particles are melted, and the droplets formed are ...
Position: Contract lecturer, University of Otago. Field: Energy management Eric grew up in the US as part of a family deeply involved in science and engineering. There was a good chance that he ...
Dr Steven Matthews’s plasma spray gun research is at present focused in two diverse areas. Both involve working in collaboration with other universities and both involve use of thermal plasma ...
In this activity, students use a simple true or false interactive tool to categorise facts. This activity could be used as a formative activity to gather students prior knowledge and ...
In this activity, students observe how the Moon appears to move across the sky each hour, as well as over several days. They discuss how both the rotation of the Earth as well as the satellite ...
Rubbish or waste is part of our lives. How we deal with it has changed through the ages. We know that out of sight, out of mind is a fallacy, and what we bury today has the potential to affect ...
Large snow events in most parts of New Zealand are uncommon. However, if you are in the South Island or the central North Island, this citizen science project could be a great one for your ...
About 14,000 earthquakes are recorded in and around Aotearoa New Zealand every year. Canterbury’s 7.1 and Kaikōura's 7.8 magnitude earthquakes and subsequent aftershocks show the constant threat ...
When St Francis Xavier Catholic School decided on the theme ‘Innovation’ as a whole-school science and technology focus, year 3 teacher Jo Collyer began searching for relevant teaching resources ...
Are you looking for ways to teach forces? If you’re new to the Science Learning Hub, you may want to start with our introductory video on teaching physics. Help, I’m teaching physics Discover ...
In thermal spray-coating, high-temperature molten droplets of material are projected at high speed to impact with the target substrate. Professor Margaret Hyland from the Chemical and Materials ...
With a background in surface chemistry, Professor Margaret Hyland, from the Chemical and Materials Engineering Department at the University of Auckland, has focused her plasma spray-coating ...
Professor Margaret Hyland, from the Chemical and Materials Engineering Department at the University of Auckland, has focused her plasma spray-coating research on the role the substrate surface ...
The size, orbit and design of a satellite depend on its purpose. In this interactive, scientists discuss the functions of various satellites and orbits. Accompanying fact files provide ...
In this simulation, students set rocket parameters before launching to see how high the rocket goes and whether they can launch the payload.
Use this interactive graphic organiser to highlight common alternative conceptions about gravity and satellites. Students can place the labels where they think they belong. This activity can be ...
