Atoms, Nuclei and Photons

Hot Star Cool Star | Tīrama, Tīrama Ngā Whetū
Blackbody radiation is explored using a halogen light bulb with a dimmer. The results are used to discuss hot and cool stars.
Star Scene Invesitgation | Te Tātari i Ngā Āhuatanga Whetū
Diffraction gratings are used to observe the "bar code" spectra of chemical elements. We use this to learn what stars are made of.

Circuits and Electromagnetism

Bicycle Generator | Pūngao Paihikara
A bicycle is used to spin a generator and power light bulbs.
Boil-up | Tōrua Korohuhū
Electromagnetic induction is used to heat a copper ring and boil water.
Eddy Current – Drag | Papa Konukura
A strong rare Earth magnet and slabs of copper illustrate electromagnetic induction and eddy currents in dramatic fashion.
Eddy Current – Tank | Te Taika Konukura
A strong magnet rolls down a copper plate, turning toward the centre of the copper plate as eddy current drag slows the inner face of the magnet more than the outer face.
Eddy Current – Tubes | Ngā Ngongo Aurere
A non-magnetic pellet falls quickly through a conducting aluminium tube but a magnetic pellet falls slowly.
Eddy Current – Vanes | Haukapo Rā Aurere
An aluminium vane swings slowly between the poles of a magnet while a plastic vane is unimpeded. A slotted aluminium vane swings at intermediate speed.
Electricity Generation | Te Mahi Hiko
An aluminium vane swings slowly between the poles of a magnet while a plastic vane is unimpeded. A slotted aluminium vane swings at intermediate speed.
Faraday's Law | Te Ture a Wharara
Faraday's Law of electromagnetic induction demonstrated with a coil and magnet.
Floating on Air | Pūkawekawe
A superconducting disk is used to levitate a magnet, demonstrating the Meissner Effect.
Jumping Ring | Porohita Pēpeke
Electromagnetic induction causes an aluminium ring to jump.
Model Hydroelectric Generator | Hiko-ā-Awa
A model hydroelectric generator powered by a garden hose operates a small light.
Model Windmill Generator | Pūrere Kapohau
A model wind turbine generator powers a small light.
Power Grid | Te Pūkawe Hiko Matua o Aotearoa
A primer on New Zealand's electricity transmission grid.
Transformers
A primer on transformers and their use in the electricity distribution grid.
Trick Magnet | Auto Nuka
One of two apparently identical steel rods passes easily between the poles of a magnet while the other unavoidably sticks to the magnet. One is stainless steel, the other mild steel.

Fluids and Thermal Gasses

Ball and Funnel | Pōro me te Ipuroa Wahanui
A bicycle is used to spin a generator and power light bulbs.
Bernoulli Plates | Ngā Perēti a Bernoulli
Surprisingly two plates are attracted when air flows out from the space between them!
Cold as Neptune - Frozen Nitrogen | Pēnā i te Mātao o Tangaroa
Pumping on liquid nitrogen causes it to freeze.
Cold Boil | Hū Mātao
A syringe is used to make water boil near room temperature.
Cold Sweat | Werawera Mātao
Evaporating liquids remove thermal energy. Sweating uses this physics to cool the body.
Cooling by Boiling | Te Whakamātao Mā te Paera
Water in a vacuum jar boils even though it is below room temperature. As the pumping proceeds, the water cools.
Floating Ball | Pōro Rewa
A ball is suspended in an upward column of air and prevented from moving sideways by the reduced pressure near the centre of the flow.
Frozen Solid | Totoka Hohoro
The behaviour of liquid nitrogen and objects cooled in liquid nitrogen.

Light and Waves

Candle Under Water | Te Mura Raro Wai
A ghostly candle appears to burn under water using a thinly-silvered mirror.
Computer Colours | Ngā Tae Rorohiko
Computer and cell phone displays, TV sets, and other imaging devices use RGB technology (red, green, and blue dots) to simulate colours and make an image.
Depth Perception | Te Whiringa Kitenga Hohonu
A series of experiments illustrating binocular depth perception.
Human Eye Resolution | Te Kokinga o te Māhea o Ngā Whatu
The angular resolution of the human eye is measured in a series of experiments: an easy to construct, astronomy-related demonstration/activity that illustrates the angular resolution of the human eye, colour sensitivity, and angular magnification.
Is It Really Yellow? | He Kōwhai Rūkahu?
An introductory human colour vision experiment: The difference between perceptive and spectral colours is examined.
Peripheral Vision | He Whiringa Kite Rewha
An experiment showing that peripheral vision is mostly colour blind. It is difficult to tell the colour of objects in your peripheral vision and they often appear black or grey.
Seeing Colours | Kitenga Ta
Human colour vision is explored in terms of cones and rods on the retina. The difference between perceptive and spectral colours is examined.

Mechanics

Faith in Physics
A heavy pendulum released from near a student's nose will return to the same height and not quite touch her/him.
On Yer Bike | He Wīra Hurihuri
A spinning bicycle wheel balances like magic while dangling from a string. The spinning wheel also causes a student to spin on a rotating stool.
