CROOKES RADIOMETER - DOUBLE 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. This double vane type has contra-rotating vanes.NOTE: This radiometer is designed for 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.

PROF BUNSEN (EF) - EXPOSE, EXCITE, IGNITE - An essential guide to whizz bang chemistry 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 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.

KINETIC THEORY MODEL This model is A robust demonstrator for the movement of molecules in A gas. A strong DC motor is connected to A vibrating platform inside an acrylic tube with A scale. The platform has A rubber surface and A set of 100 small stainless steel balls is loaded into the tube. As the motor is changed in speed (simulating the heating of A gas), the agitation of the balls changes inside the tube. A light polystyrene foam disc is placed in the tube and it floats on the agitated balls at A certain height. A second heavier disc can be added or can replace the first. An approximate relationship between the floating height (volume of the gas) and the weight of the discs (pressure of the gas) can be seen. Code: IEC0198.
