Go around your house and hit (or tap) ten different objects. The objects should be different shapes and made of different material (choose things to hit that won’t break!). Each object is a different medium for sound. Try to hit each using the same amount of energy. Describe each object that you hit. What is its shape and what is it made of? Then describe how it sounds to you. Does it transmit sound well? Does it absorb sound? Is the sound loud or soft? Is there a “ring” to the sound? Does it sound like a “thunk” or does it sound like a drum? Rank the ten objects from loudest to softest. Draw some conclusions based on your results from Steps 1 and 2. For example, are there a certain shapes or materials that are better or worse media for sound travel?

Explanation:

ball ( it sound like thup thup it is softly harsh in voice )

book ( tak tak it is hard in voice )

bed ( pat pat it is soft in voice )

Door, window, picture, floor,stairs, wall, desk, backpack, paper, bed all of these produce different sound.

What do you mean by sound?

The term sound is defined as an acoustic wave is a vibration that travels through a gas, liquid, or solid transmission medium. In terms of human physiology and psychology, sound is the brain's receipt of these waves and perception of them.

A mechanical disturbance that causes an equilibrium condition to be disturbed and propagates by an elastic material medium.

The vibration of an object creates sound, which travels from one place to another by a medium. Vibration is the phrase used to explain an object's to-and-fro or back-and-forth motion. Vibrations are generated by objects in motion.

Therefore, stairs, wall, door, window, picture, floor, desk, backpack, paper, bed all of these produce different sound.

ITS EASYRead the following passage carefully and answer the questions given below:i. Polythene shopping bags and wrappers are a potential threat to urban environment. Once you have discarded them after use, you do not lose your link with them. They return to you in a variety of ways, though you do not realise it. For example, they choke your drains and provide breeding facilities to deadly germs.ii. A recent study has shown that about 250 tonnes of plastic waste come out of various colonies of major cities every day. This disrupts the sewer system, the essential arteries of city life, choke the land mass and clog the pores of the wetlands.iii. Unfortunately, even the villages and small towns are not free from this danger. Millions of people returning to their home towns everyday carry their shopping in colourful bags. This pleases their family and children, who after preserving them for a time dispose them in wells, rivers, tanks and drains. Many throw them off into the fields. They do it with a sense of pride, to show off. When their neighbours see that their men from the cities regularly send them those good things of life, they are impressed.iv. All over the world the worst offenders are the upper income groups of the so-called posh colonies. Though educated, the residents of these affluent areas are unaware of the damage done by the plastic bags. Millions of children in schools carry their lunch boxes in plastic bags. They callously throw them away and cause an unhealthy environment.v. As it is convenient for mothers to wrap the food in plastic, it is difficult to persuade them against doing this. According to a drill master of a school, it becomes a drill to clean the fields after the children leave. When the midday meal scheme is fully implemented, it must be seen that no plastic wrappers are used.vi. As these wrappers are light in weight, they are borne aloft by the wind causing visual shocks. Unlike cotton or paper bags they remain undissolved in the mud and stop rain water from seeping deep in the earth. This affects the natural growth of greenery.Questions:a. How do polythene bags become health hazards?b. What are the findings of the latest research about plastic waste?c. How do the school children pollute the environment?d.
