Dian Fossey was a good researcher. But‚ what is a researcher? One who conducts research? Surely that is the correct definition‚ but to properly understand the definition we would then have to define the word research. Research is the process of collecting data and information in order to obtain knowledge about the research topic. With these definitions we can say‚ without a doubt‚ that Dian Fossey was a researcher. But why was she a “good” researcher? By reading the book ‘Gorillas in the Mist’ we

SHAMINMENISHA How Water Rockets Work A water rocket works using the same principles as other rockets. There are three main forces in action: thrust (Fapp)‚ drag (Ffr) and weight (w=mg). The water‚ which is forced out by the difference between internal and atmospheric pressure‚ is a reaction mass that provides the thrust. All rockets have a reaction mass‚ which can vary from hot gasses that are expelled when a fuel is burnt (in the Space Shuttle’s SRB’s for example) to water in a water rocket. The

Activity 1: X-Gliders Lesson Objective: Campers will learn about the forces of flight‚ weight and balance when they construct a glider. As they improve the design of their glider they will understand that a variable is a single change in the engineering. Set-Up: Each student will need two foam trays‚ a plastic knife and an x-glider template. Materials for weight and balance can be distributed at a communal table. Demo and discussion: Start off the lesson by asking your campers‚ “What are gliders

INTRODUCTION Traffic jams are the bane of any commuter. Many of us spend an hour or so stuck in traffic every week. The growing population is partly to blame for our congested roads‚ but the main problem is that we are not expanding our transportation systems fast enough to meet ever increasing demands. One solution is to create a new type of transportation that doesn’t rely on roads‚ which could one day make traffic jams a 20th century relic. To do this‚ we must look to the sky and water. WHY

The novel "Tomorrow When the War Began" successfully conveys the idea that the average person can be thrust into a warlike situation‚ and the reality of the war will had a large impact on their life which will force changes to take place. Ellie and her friends are an example of a group of teenagers‚ who consider themselves to be ’average’ and ’innocent’

RULES GOVERNING SHIPMENT BY SEA: HAGUE RULES‚ HAGUE-VISBY RULES AND HAMBURG RULES The nature of the Hague-Visby Rules was discussed by the House of Lords in The Hollandia [1983] AC 565 (HL). The plaintiffs (shippers) shipped a piece of road-finishing machinery on board a Dutch vessel‚ ‘The Morviken’‚ belonging to the defendant carriers to Bonaire in the Dutch West Indies. The bill of lading issued in England limited the carriers liability to Dutch Florins 1‚250 ($250) which was less than the 10

The engine’sexhaust gases do not contain enough energy‚ compared to a jet engine‚ to create significant thrust in the propulsion of the aircraft.The propeller is coupled to the turbine through a reduction gear that converts the high RPM‚ low torque output to low RPM‚ high torque. Turboprop engines are generally used on small subsonic aircraft‚ but some aircraft
