Discussion At the end of this lesson class, you will be able to: a. state the definition of star; b. recognize the importance of stars in the universe; and c. explain the characteristics of stars Based on your activity a while ago and tried to observe the stars in the universe, do you think stars have the same sizes? colors and No, sir. brightness? Why do you say so? I think because of their distance sir. Precisely! You’re truly a good observant. There are stars that seems to be so near and far to us. Is Sun a star? Yes, sir. Good. But remember that, not all stars are Stars are sun. Let’s take a look with this, Jaybee kindly read on the screen the definition of a star. • A massive hot ball of gases that emit energy in the form of light. • They differ in brightness, color and temperature. • A person can only see an average of 3, 000 stars. Centro, Sto. Tomas, Isabela 3327 300606@deped.gov.ph “STNHS: Tahanan ng Karunungan” Classroom Observation 4 This means that, stars are very hot in nature. Helium and Hydrogen are the gaseous elements present in a star. Have you notice Yes, sir. Some of them are so bright but some are their brightness? not. Yes, remember that, no matter how big or small a star is, the one that is near to us is the brighter. But if these two are in the same distance, the bigger star is the brighter one. Of course, if they differ in brightness, so with its color and temperature. What is the color of very known star to us; Sun? Yes, Acky? Yellow, sir. Good. A while ago, we sang twinkle, twinkle little star. Do stars really twinkling? Yes, sir. How do you say so Manilyn? It sparks, sir. Mind you class that they don’t twinkle. As it reaches the atmosphere, it passes through layers of wobbling air or turbulent moving air before reaching our eyes, causing it to twinkle. Let us watch and observe each star to be presented on screen. What have you notice to the following stars? Their distances and colors. Is the nearer star the brighter or the farther The nearer, sir. one? What about their colors? What have you The darker, the hotter and the brighter the cooler. notice? Exactly! D. Application There are actually two classifications of stars, the hot and cool stars. Observe the Centro, Sto. Tomas, Isabela 3327 300606@deped.gov.ph “STNHS: Tahanan ng Karunungan” Classroom Observation 5 colors of the flame in this candle. Can anyone Blue, Red and Orange, sir. tell me the colors present in this candle? Great! Which one is the hottest and the coolest? Blue is the hottest while Red is the coolest. Amazing! Again, there are two classifications of stars, the hot and cool star. Under hot stars, these are blue and white colored stars while the cooler star is red- and orange-colored stars. What have you notice to the HR Diagram? As the color becomes darker, the temperature decreases. Absolutely! E. Values Integration What do you think is the importance of having stars in the universe? Our universe will be boring and we will only see darkness. Aside from what MJ said, any other thoughts on its importance? Yes, Alfie? People would be hopeless without stars in the universe. Exactly! Imagine there will no Sun, there will be no life on this earth. F. Generalization Let’s wrap up what we had discussed. Can anyone of you define a star? Yes, A-Jay? A massive hot ball of gases that emit energy in the form of light. How about its categories? There are actually two, yes, Adan? Hot and Cooler stars. Lastly, if blue stars are hotter and red stars are cooler according to its color indication, how about its luminosity and color? Brighter stars are blue and dimmer stars are red. Do you have any further clarifications and suggestions about our topic? None, sir. Centro, Sto. Tomas, Isabela 3327 300606@deped.gov.ph “STNHS: Tahanan ng Karunungan” Classroom Observation 6 IV.
