In Levers, inhabitants of Mammoth Island have decided to enter their mammoth in a "heaviest mammoth" competition. To do so, they need to find the best method to weigh a mammoth. After observing some children playing on a see-saw, Olive, a young islander, is inspired to try a simple machine called a lever to get the job done. The Islanders then explore the properties of the three classes of levers and discover that scissors, nail clippers and tweezers are just a few examples of useful inventions based on the principle of the lever!
In Screws, inhabitants of Mammoth Island are in the process of building a new observation tower out of stone blocks when one of the islanders gets trapped at the top of the tower. With the help of a visiting gallant knight and his trusty mammoth, they are able to build a ramp around the circular structure and create a giant simple machine known as a screw. Turning the tower into a giant screw allows the islanders to spin the tower down into the soil, bringing the trapped inhabitant of Mammoth Island close to the ground -- and saving the day!
In Engines, inhabitants of Mammoth Island look for an alternative to mammoths to speed up pizza delivery. They decide to experiment with different engines and discover how each works -- from simple rockets to turbofan jet engines to gasoline engines. Comparing the advantages and drawbacks of these internal combustion engines, the islanders determine which one will serve their business best and ensure that their pizzas are delivered on time.
The Real Time DVD can either be used in the classroom or for individual study. Each DVD has six episodes. The main focus of each episode is to provide a context for the language in the Real Time sections in the Students’ Book. It would therefore be suitable to watch one episode after having completed one Real Time section.
Each episode is divided into three scenes. There are interactive multiple-choice questions for each scene which you can use while watching. We suggest letting students see the question, watching the scene, then having a class vote on the answer.
Students retain geography and history information better when they experience living images of world cultures. These programs about some of the world’s major countries help students understand other peoples’ environments, values, and significant historical contributions.
