CROOKES RADIOMETER - DOUBLE VANE Quick enquiry. Where to buy Suppliers range | Comprises A partially evacuated glass bulb containing one set of four mica vanes mounted on A pivot. One side of each vane is blackened, the reverse side shiny. The presence of heat or light energy causes the vane to rotate. This double vane type has contra-rotating vanes.NOTE: This radiometer is designed for light">demonstration purposes using A heat or light source to provide the energy to rotate the vanes and will not necessarily work when exposed to sunlight. If the sun is too high in the azimuth its rays will not strike the vane at the correct angle to provide sufficient energy for them to rotate. Code: HE0096. Suppliers to schools & laboratories of science equipment & laboratory grade chemicals. | Science & Lab Supplies NZ |
CROOKES RADIOMETER - SINGLE VANE Quick enquiry. Where to buy Suppliers range | Single Vane: Comprises A partially evacuated glass bulb containing one set of four mica vanes mounted on A pivot. One side of each vane is blackened, the reverse side shiny. The presence of heat or light energy causes the vane to rotate.NOTE: This radiometer is designed for light">demonstration purposes using A heat or light source to provide the energy to rotate the vanes and will not necessarily work when exposed to sunlight. If the sun is too high in the azimuth its rays will not strike the vane at the correct angle to provide sufficient energy for them to rotate Code: HE1757.

LASER - PHILIP HARRIS: RECEIVER UNIT ONLY Quick enquiry. Where to buy Suppliers range | A separate modulated laser receiver is required for demonstrating the transmission of information via A modulated laser beam and for simple speed of light determinations. A built-in speaker is incorporated for listening to signals received within the audible range. If A high level of volume is required, (i.e. light">demonstration in A classroom situation) A separate amplifier/speaker system is recommended. Operating voltage - 9volt battery. Frequency response - 100Hz to 5MHz. Size - 120 x 65 x 35mm Code: A46176. Suppliers to schools & laboratories of science equipment & laboratory grade chemicals. | Science & Lab Supplies NZ |
PROF BUNSEN (EF) - EULER'S DISK Quick enquiry. Where to buy Suppliers range | Give the disk A spin on the concave mirrored surface and it will keep spinning and rolling like A coin . . . A coin that doesnt seem like it will ever stop. An impressive light">demonstration on the conservation of energy and angular momentum with A constant change in sound pitch and speed. Amazing to use in A darkened room with flashlight or low powered laser as it comes with holographic magnetised disks and wedges. Very easy to operate. NO batteries required - physics will do it. A great gift and irresistible desk toy! Size: The mirror is 20 cm in diameter. Teach: Perpetual motion, conservation of energy, angular momentum Code: PBSE10. Suppliers to schools & laboratories of science equipment & laboratory grade chemicals. | Science & Lab Supplies NZ |
PROF BUNSEN (EF) - EXPOSE, EXCITE, IGNITE - An essential guide to whizz bang chemistry Quick enquiry. Where to buy Suppliers range | In this one book you will get the explanations, the practical show-how, the safety issues and extension ideas to take your students to the next level. This is not A chemistry recipe book. It is A practical chemistry revelation. No boring recipes on making fizzy volcanic mountains (yawn) - this stuff sizzles. The author focused on the triple S concept: All activities are SIMPLE, reasonably SAFE (hey, this is about combustion) and oh so SPECTACULAR. Youll get step-by-step instructions and photos and all can easily be implemented in your classroom and lab - instant student engagement. For those who love safe, sizzling science excitement at home - you have found it! The tested activities will provide hours of solid Whizz-Bang edutainment in the backyard that should (due to the nature of the activities) be overseen by an adult. This book will show you how to: make A pencil sharpener burn white hot under water; make an egg explode in an eggsothermic" reaction; make A wind-up toy car explode in A puff of smoke; prepare hydrogen gas from kitchen chemicals; launch A real rocket using sugar-based fuel; make A tube whistle, bark and fly skywards; do A sugar dust explosion in A coffee tin; extract silicon from beach sand; set your hand (safely) on fire; boil water in A paper pan; and more . . . Chemistry teachers - this is the book you have been yearning for as it contains the fun light">demonstrations students are expecting from you, plus the explanations. Now you too can become part of the Whizz-bang clan. Light the bunsens and celebrate the joys of chemistry! For: Middle & High School Science teachers, home experimenters & amateur scientists, great gift too! Pages: 115 pages, Black & White Size: 23.4 x 15.6 cm Code: PBSZ12.

PROF BUNSEN (LC) - ASTRO BLASTER Quick enquiry. Where to buy Suppliers range | Take four high bounce balls, thread them on A plastic spindle and drop them straight downward onto A hard surface . . . Watch out! The top ball will fly off the spindle to reach heights up to 10 times the original drop!! This makes an amazing physics classroom light">demonstration and puts the Law of Conservation of Momentum in the lime light. Can be very handy to visualise discussions on impulse and momentum conservation during car crashes. It also illustrates the forces and laws at work during the creation of A supernova. (Information included) Included: Spindle with four elastic balls, two spare red balls, one pair of safety glasses Teach: Law of Conservation of Momentum, Conservation of Kinetic Energy in elastic collisions Age: 8+ with adult supervision. Please wear safety glasses (included). Code: PBSF07. Suppliers to schools & laboratories of science equipment & laboratory grade chemicals. | Science & Lab Supplies NZ |
SOLAR ENERGY light">DEMONSTRATION APPARATUS Quick enquiry.
