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 ...
Fusion is the process occurring within the plasma core of our Sun in which the nuclei of lighter atoms link to form a heavier atom. For example, when hydrogen nuclei collide, they can fuse into ...
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 ...
In this activity, students use a scale model of the Earth and identify altitudes of various satellites. They then use a smaller object on a string to model gravity and satellite motion. By the ...
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 New Zealand every year. Canterbury’s 7.1 and Kaikōura's 7.8 magnitude earthquakes and subsequent aftershocks show the constant threat ...
Rocket science includes ideas of forces and motion, how rockets work and some of the challenges for those wanting to make rockets go faster and higher. This teaching sequence introduces students ...
Long ago, according to the legend of Māui, the Sun was the focus of attention. People wanted more daylight and warmth to get their jobs done. Māui schemed to harness the Sun. Scientists today ...
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 ...
