WRITING (ask and answer questions)WHY? There are some books that are a collection of interesting questions that have appeared during a period of time in a magazine, with different readers answers. Give students a sample or two of these. ( Tank Madness from Why penguins don´t get their feet wet? And Baarmy). (Why do goldfish jump out of their tank? Different answers , why do sheep run in a straight line in front of a car? Different answers) Read it out loud, ask them for the different answers in their own words. Divide students into pairs or threes. Give them a piece of paper. (they can only write on one side). Each group writes a question and passes the piece of paper to the next group, who will answer and pass it on to the next and so on until it gets to the original group, who wrote the original question and will now answer it. IT IS VERY IMPORTANT TO GO IN STRICT ORDER. The teacher can walk around correcting mistakes. When everyone has answered all the questions. The group that wrote each question will read it and its different answers to the rest of the class. You can display it on the wall or noticeboard at the end of the lesson with the heading WHY…? https://books.google.es/books?id=5lkxPN59udQC&printsec=frontcover&dq=new+s cientist+magazine+last+word+column&hl=es&sa=X&ved=0ahUKEwjAvpWe6qzKAh VItxQKHS_xCTcQ6AEIOjAC#v=onepage&q=new%20scientist%20magazine%20last %20word%20column&f=false Why don't penguins' feet freeze? Asked by Leanne Ryan Penguin’s feet don’t freeze, but they are often very, very cold. Penguins need bare feet so they can walk without slipping and to help steer them when swimming. Penguins often avoid their feet getting too cold by hunching down so that their belly feathers cover their feet, or by rocking back onto their heels and tail to lift their feet off the ice. They also have counter-current heat exchangers that regulate their foot temperature to keep them at least just above freezing. If their feet were too warm, they would waste lots of energy. Blood vessels running away from the feet run close to those running to them, so that just the right amount of heat can be transferred between them to keep the feet warm enough. If they get too cold, the amount of warm blood flowing to the feet can also be increased by increasing the diameters of the arteries running to the feet.
