The Grid Question of Science Final Asessment Semester 2022

Assalamualaikum warohamtuloohi wabarokatuh

How are the students in class VIII-G and VIII-H? Hopefully you will always be in a healthy condition and stay enthusiastic in carrying out Science Final Asessment International Class. There are 25 multiple choice questions questions for this assesment. The materials about the light, sound, and human excretory system. Here are there materials for sience final assesment : 

1. Students can mention the example of refelection and refraction.  
2. Presented the picture of diagram shows a parallel beam of light is incident on a plane mirror, students can determine how the beam is reflected by plane miror.
3. Presented the picture of diagram shows the formation of a real image, students can determine the formation of a real image of an object O placed in front of a converging lens.
4. Student can mention the cause of the change in direction when light travels from air into glass.
5. Presented a data about the object in front of a concave lens with focus 6 cm and the object distance is 6 cm, students can calculate the image distance and determine the location of image
6. Presented a data about the object in front of a concave lens is 12 cm, the high object is 18 cm, and the focal lenght of object is 30 cm, students can determine the characteristic of image
7. Presented a data about the object in front of a convex lens is 36 cm, the high object is 72 cm, and the focal lenght of object is 60 cm, students can determine the characteristic of image.
8. Presented the picture of wave, students determine the wavelengt and the amplitude of the wave.
9. Presented the data about an echo-sounder on a ship produces a pulse of sound. The echo is received by the echo-sounder after 6 second. The speed of sound in sea-water is 4500m/ s, Students can calculate the depth of the sea-water below the ship.
10. Presented a data of a wave has a waveleght of 20 m and a frequency of 8 Hz, students can calculate the speed ofthe wave.
11. Students can determine the frequency produces a sound that can be heard by a human.
12. Presented the statments about sound wave, students can determine the true statements about sound wave. 
13. Presented the data a car moves at 40 m/s away from a whistle. The whistle is stationary. The whistle makes a sound with a frequency of 2000 Hz. The speed of sound in air is 340 m/s. Students can calculate the frequency observed by the driver of the car.
14. Presented the data of simple pendulum vibrates 150 times in 30 seconds, students can calculate the period and the frequency of the pendulum.
15. Presented the statement about some one who suffer myopi, students can calculate the focal leght of the eyeglasses if a somene advised by doctor to wear concave lens glasses with a lens power of 4.5 diopters. 
16. Students can mention the condition for resonance to occur.
17. Presented the data on the table about the function of the human urinary system, students can determinte the correct function of its part. 
18. Presented the diagram shows part of the excretory system, students can mention the function of ureter, uretra, and bladder.
19. Students can determine the functional unit of the kidneys which includes the glomerulus, Bowman’s capsule, tubules and the Loop of Henle.
20. Presented the diagram of nephron, students can determine the right parts of the nephron based of the name.
21. Presented the part of nephron, students can determine a mechanism will be affected if in certain disorder occurs in part of nepron.
22. Presented a table of composition of urine, students can determine the two components listed above that are completely reabsorbed from the glomerular filtrate before it becomes urine.
23. Students can mention the contain of sweat.
24. Students can determine the correct sequence for the flow of urine from the body.
25. Presented the statements of a diseases excretory system, students can mention the name of a diseases based of its characteristics. 

Hopefully the students of class VIII-G and VIII-H will be given fluency in answering science tryout which will be held on Thursday, June 9, 2022. Keep the enthusiasm for learning and always keep your health. Aamin
