The locations of stars in the sky relative to one another do not appear to the naked eye to change, and as a result stars are often considered to be fixed in position. Many unaware stargazers falsely assume that each star has its own permanent home in the nighttime sky.
In reality, though, stars are always moving, but because of the tremendous distances between stars themselves and from stars to Earth, the changes are barely perceptible here. An example of a rather fast-moving star demonstrates why this misconception prevails: it takes approximately 200 years for a relatively rapid star like Bernard's star to move a distance in the skies equal to the diameter of the Earth's moon. When the apparently negligible movement of the stars is contrasted with the movement of the planets, the stars are seemingly unmoving.
Pre-listening tasks
1
What/s you guess;the words and expressions on the blackboard will help students to guess the theme of the listening text; location of stars ,sky naked eye. to be fixed in position .permanent home .tremendous distances .fast-moving stars ,negligible movement. seemingly unmoving
2 The same list of the words
Each student is given a couple of words .They are to explain their meaning to one
another in pair. Students may refer to the dictionary ,if they need. While-listening tasks 1.Gap-fill Students are given a tapescript and are to fill the blanks while listening to the text ; 1The location of----in the --- can’t be seen by---. 2Some people consider them to be----. 3.They think.that each star has it’s own--- ----. . 4.In reality stars are --- ---. 5.The--- between the stars is----. II.Multiple choice; 1.The location of the stars in the sky do not appear to the. a .telescope b.naked eye c.unaware stargazers. 2.As a result stars are often considered a.to move very fast b.to be fixed in position c.to move 200km per hour 3.The apparently negligible movement of the stars is contrasted with the movement of a.space rockets b.the planet c.planes. Ticking-off items /bingo/,when students listen to list of words and tick them off as they hear. III.Post-listening tasks; 1.Teacher can check understanding by asking students to summarize the information in writing or orally/ 2.Ask students to have a short discussion about the topic.
3.Information Exchange Students share the information with each other. 4.Test for Classmates One of the best post –listening activities consists in quizzing classmates .Teacher may ask students to prepare a set of questions.that another student will have to respond.They can prepare multiple-choice quiz, short answer questions,true and false statements.
