1. 0:04What's up mga kaguro at mga mag-aaral?
2. 0:06Ako muli ang inyong science teacher para
3. 0:08sa panibago na namang videong lesson.
4. 0:10Dako muli tayo sa isang lesson sa
5. 0:12general science at ito ay kadugtong ng
6. 0:16ating nakaraang video tungkol sa
7. 0:17properties of light and sound. Topic na
8. 0:20ito ay ang different innovations and
9. 0:22technologies related to slight and
10. 0:25sound.
11. 0:27Let's have first an activity. Let's have
12. 0:29this word cloud. Take a look at this
13. 0:32picture. Examine the pictures. List down
14. 0:36all the words related to the picture to
15. 0:38create a word cloud.
16. 0:44Another activity and this is entitled
17. 0:46what if each group will be assigned into
18. 0:50four different fields namely classroom
19. 0:53learning commuting or traveling
20. 0:56socializing or participating in group
21. 0:58activities and playing sports or games.
22. 1:02Each group will list down at least three
23. 1:04scenarios on what if there was no light
24. 1:07or sound on their assigned fields.
25. 1:13What are the importance of light and
26. 1:15sound? Light and sound essentially used
27. 1:18in communication, entertainment, safety,
28. 1:22medicine and navigation. Ang light at
29. 1:25sound ay hindi lang basta-basta
30. 1:27phenomena. They are vital tools used in
31. 1:30our daily lives from the lights that
32. 1:32guide us to the sounds that warn us.
33. 1:36Understanding how they work leads to
34. 1:38better and more efficient technologies.
35. 1:42Light and sound are essential parts of
36. 1:44our daily lives. Over the years, many
37. 1:47innovation have been developed to use
38. 1:50the properties of light and sound in new
39. 1:53and exciting ways. Technologies such as
40. 1:55leads, holograms, and lasers have
41. 1:59transformed how we see and new light.
42. 2:03While soundprofing materials and sound
43. 2:05amplifiers have changed the way we
44. 2:07manage and experience sound.
45. 2:10Understanding these technologies help us
46. 2:13appreciate their significance in fields
47. 2:15like communication,
48. 2:17entertainment, medicine and safety.
49. 2:24What are innovations related to light?
50. 2:27Here are the innovations that are
51. 2:30related to light. Leads or light
52. 2:33emitting diodes, energy efficient
53. 2:36lighting, lasers used in medicine,
54. 2:40industry, entertainment holograms used
55. 2:43for making 3D images for visuals, art
56. 2:47and security and optical fibers for
57. 2:50highspeed communication networks. Kung
58. 2:53may LED or LED sa bahay ninyo, then you
59. 2:56already benefit from innovation. Lasers,
60. 2:59ginagamit sa ey surgeries. katulad ng
61. 3:02laic and barcode scanners. Cool 'di ba?
62. 3:07What are the innovations related to
63. 3:09sound? We have soundprofing materials
64. 3:13which absorb or block sound, sound
65. 3:16amplifiers which are used in
66. 3:18microphones, speakers, ultrasounds which
67. 3:22are used in for imaging in medicine and
68. 3:26noise cancelling technology used in
69. 3:29headphones. Tunog din ay makapangyarihan
70. 3:32with amplifiers. Kahit maliit ang boses
71. 3:35naririnig ng marami. Sa mga ospital,
72. 3:38ultrasounds help see inside body without
73. 3:42cutting it open.
74. 3:46[Musika]
75. 3:49These are other real word applications
76. 3:52of light or sound. We have leads for
77. 3:55traffic lights, flashlights, and
78. 3:57gadgets, lasers for surgeries or metal
79. 4:01cutting, holograms for stage visuals,
80. 4:04security and seals, soundproping for
81. 4:07studios, theaters, and amplifiers for
82. 4:11concerts, classroom, and hearing aids.
83. 4:13Napaka-useful ng mga ito. Lahat ito ay
84. 4:16makikita mo sa paligid, schoolman, sa
85. 4:19bahay o kalsada. talagang pinapadali
86. 4:21nila ang buhay natin.
87. 4:24Let's have an activity and it's called
88. 4:27Light and Sound at Home and School.
89. 4:30Think about your day from paggising
90. 4:32hanggang sa pagpasok sa school.
91. 4:35Ano-anong bagay ang ginagamitan ng light
92. 4:37and sound? Let's list them. These three
93. 4:40things that are light and sound related
94. 4:42technologies found at your home and at
95. 4:45your school.
96. 4:48Let's have another activity and it's
97. 4:50called lasers in our daily life. Scan
98. 4:52the QR code and watch the video. Lasers
99. 4:57in our daily life.
100. 5:00Then answer the following questions.
101. 5:02Number one, what does the word laser
102. 5:04stand for? What are the things mentioned
103. 5:07in the video that uses laser technology?
104. 5:11And what are the applications of lasers
105. 5:14mention in the video?
106. 5:19Laser safety precautions. Kung kayo ay
107. 5:21gagamit ng laser, never point a laser at
108. 5:24your eyes or others. Do not aim lasers
109. 5:28at reflective surfaces.
110. 5:31Use appropriate laser safety goggles.
111. 5:34Use lasers in controlled areas avoid
112. 5:38skin exposure to high powered lasers
113. 5:42turn off lasers when not in use. And
114. 5:45read and follow the manufacturer's
115. 5:47instructions.
116. 5:50DVT 2.
117. 5:52Sound application and stoscope. Scan the
118. 5:56QR code and watch the video about sound
119. 5:58application and stoscope.
120. 6:01Answer the following question. What is
121. 6:04the stethoscope and what it is used for?
122. 6:07How is the sound being amplified by the
123. 6:09diaphretoscope?
124. 6:14Tvity 3. Build a DIY sound from room.
125. 6:19Apply what we learned. Gumawa tayo ng
126. 6:21maliit na kwarto at subukan kung anong
127. 6:23materials ang best pang-block ng sound.
128. 6:26The objective of this activity is to
129. 6:28test which kind or kinds of materials
130. 6:31black and dumpen sound effectively. The
131. 6:34following are the materials needed in
132. 6:36the activity. mobile phones with
133. 6:39installed decibel meter app, small
134. 6:42speaker, cardboard box or shoe box,
135. 6:46writing materials,
136. 6:48foam, towels, bubble wrap, egg cartons,
137. 6:53cardboard, felt paper, plastic wrap, and
138. 6:57aluminum foil. So using the materials,
139. 7:00build a box around a speaker or a
140. 7:02cellone use as decibel meter test the
141. 7:06sound.
142. 7:094. Make your own hologram. Pwede kang
143. 7:11gumawa ng hologram gamit lang ang
144. 7:13plastic at cellphone. Try this
145. 7:15experiment at home or in your class.
146. 7:18This activity will help you to build
147. 7:20your own hologram and create a 3D image
148. 7:23using simple materials. The materials
149. 7:26needed are plastic bottle, drop paper or
150. 7:29ruler, pen or marker, seesors or craft
151. 7:34night, tape or glue, smartphone or
152. 7:37tablet with a YouTube hologram video.
153. 7:40Search for hologram pyramid video. Using
154. 7:43the plastic sheet, you can make a
155. 7:46projector and watch a hologram video on
156. 7:49your phone.
157. 7:51PBT 5, lead art. Kung mahilig ka sa
158. 7:54hearts and craps, this is for you. Use
159. 7:57your creativity and light it up with
160. 7:59lead. This activity will help you to
161. 8:01create any art showcasing light emitting
162. 8:04diodes or LED.
163. 8:06And their role is in the craft such as
164. 8:09electronic puzzles, wearable fashion,
165. 8:12greeting cards, lanterns, etc. The
166. 8:15materials needed for this activity are
167. 8:17leads, dry cells, and copper wires or
168. 8:20speaker wires.
169. 8:22So, you will create a greeting card or
170. 8:24mini poster that lights up.
171. 8:28Let's wrap up what we have discussed
172. 8:30today.
173. 8:32It's time to reflect what technology do
174. 8:34you appreciate the most. What idea do
175. 8:37you have? Bakit kaya ikaw na ang next
176. 8:41inventor na may kinalaman sa light and
