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 try out (asessment) IV International Class. There are 15 multiple choice questions questions for this assesment. The materials about the light, sound, and human excretory system. Here are there materials for try out science of class VIII-G and VIII-H :
1. 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.
2. 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.
3. Students can determine the image will be formed by a plane mirror.
4. 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.
5. Presented a data about an object 24 cm high is in front of a concave mirror with a focal length of 60 cm. If the object is 60 cm from the mirror, students can determine the characteristic of the image formed.
6. Presented the picture of wave, students determine the wavelengt and the amplitude of the wave.
7. 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.
8. Students can determine the frequency produces a sound that can be heard by a person.
9. 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.
10. Presented the data about a simple pendulum vibrates 100 times in 10 seconds, students can calculate the frequency of the pendulum vibration.
11. Presented the diagram shows part of the excretory system, students can determine the the correct structure based on this sign part.
12. Presented the data on the table about the function of the human urinary system, students can determinte the correct function of its part.
13. 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.
14. Students can determine the functional unit of the kidneys which includes the glomerulus, Bowman's capsule, tubules and the Loop of Henle.
15. Students can determine the diseases of human excretory system based on the statements.
Hopefully the students of class VIII-G and VIII-H will be given fluency in answering science tryout which will be held on Monday, May 23, 2022. Keep the enthusiasm for learning and always keep your health. Aamin
