Covering a range of STEM topics from nocturnal animals to climate change, Do You Know? takes an enquiry-based approach, developing children's language, communication, and investigation skills. Recommended for children aged 7+, there are four levels progressing from CEFR level Pre-A1 to level A2. Each reader is accompanied by online video content, audio, video, and comprehension activities, and suggestions for project work.\u003cbr\u003e\u003cbr\u003eIn the Air, a Level 2 Reader, is A1 in the CEFR framework and supports YLE Movers exams. Short sentences contain a maximum of two clauses, introducing the past tense and some simple adverbs.\u003cbr\u003e\u003cbr\u003eBirds fly by flapping their wings, which generate lift and thrust. The shape of their wings, the angle at which they are angled, and the speed at which they flap their wings all contribute to the lift and thrust generated. Birds use a combination of flapping their wings and soaring through the air to stay in the air.\u003cbr\u003e\u003cbr\u003eJet engines move a plane by burning fuel and expelling exhaust gases. The fuel is burned in the engine, which creates hot gases that expand and push out the back of the engine. The exhaust gases are then directed through a turbine, which generates electricity that powers the engine and propels the plane forward.\u003cbr\u003e\u003cbr\u003eHelicopters are a type of aircraft that use a rotor to generate lift and thrust. The rotor is a spinning blade that rotates around a central hub. The lift and thrust generated by the rotor are used to lift the helicopter off the ground and keep it in the air. Helicopters can fly in a variety of conditions, including calm winds and rough terrain.\u003cbr\u003e\u003cbr\u003eGliders are a type of aircraft that use air currents to generate lift and thrust. The glider is designed to fly in the air without the use of an engine. The glider is towed into the air by a powered aircraft, which releases the glider at a certain altitude. The glider then uses the air currents to stay in the air and generate lift and thrust.\u003cbr\u003e\u003cbr\u003eThe science of flying is a complex field that involves a combination of aerodynamics, thermodynamics, and mechanics. Aerodynamics is the study of the forces that act on an aircraft as it flies through the air. Thermodynamics is the study of the heat and energy that are generated by an aircraft as it flies. Mechanics is the study of the forces that act on an aircraft as it moves through the air.\u003cbr\u003e\u003cbr\u003eIn conclusion, birds fly by flapping their wings, jet engines move a plane by burning fuel and expelling exhaust gases, helicopters use a rotor to generate lift and thrust, and gliders use air currents to generate lift and thrust. The science of flying is a complex field that involves a combination of aerodynamics, thermodynamics, and mechanics.\u003c\/p\u003e\u003cp\u003e                            \u003cstrong\u003eWeight\u003c\/strong\u003e: 154g                            \u003cbr\u003e\u003cstrong\u003eDimension\u003c\/strong\u003e: 198 x 253 x 6 (mm)                            \u003cbr\u003e\u003cstrong\u003eISBN-13\u003c\/strong\u003e: 9780241503409                                                      \u003c\/p\u003e","brand":"Ladybird","offers":[{"title":"Paperback \/ softback","offer_id":44099152314618,"sku":"9780241503409","price":3.65,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0522\/4297\/2845\/products\/0a5e1bc98f0e52c100ea9f6d248ad5f6.jpg?v=1635826658","url":"https:\/\/shulphink.com\/products\/do-you-know-level-2-in-the-air","provider":"Shulph Ink","version":"1.0","type":"link"}
