Chapter 1 - Sound Energy

Acoustic energy is an exceptional starting point Explore and observe natural phenomena
Around us. Sound waves are heard by humans with ou r The ears are only a very limited range of sound spcctrum. Our perception of sound reduces us to “listen”. Only a narrow segment of energy ranges from 20 Hz to 15 Kilohertz. In facl there is a full set of aud io above either And under our domain. Which we cannot realize in ll But they're really interesting to explore.

In this chapter we will explore inner comfort Audible worlds. Ultrasound. And sub-sonic sounds.
You will check how to listen to high frequency Animal sounds, remote chats and how
To track noise and macbine errors using the electronic stethoscope. You will discover a whole new
The universe of undisturbed waters appears as feet p IO amplifier and subwoofer. you will learn
That the ngitudi nal mechanical wave has iterative power Less than the audible range is called sub-molecular Wave (light waves are low red waves Light). Which is more than the frequency of the audible
The range is called ultrasound (1IItrtlL'iolet waves) RC over light viole t). 111e the longest wavelength sound Waves can affect the human ear nomml (20 Hz) Reset a thousand times as long as the shortest waves to Where r r is sensitive (20,000 Hz).


Chapter 2 Light detection


And measurement Although about ten million shades can be Identified by the human eye in the visible spectrum From ligl1l. 
The light that produces those colors stretches Only along the narrow wave. TIlis frequency

If we repeat, count all the waves that hit On all shores of the earth. You will have to

Chapter 3 - Heat detection


Shifa moves from one place to another in Three ways: by connecting. Economic Cooperation Organization. Or radiation. Conductive electricity is the process of transferring heat from it Molecule to molecule in a substance. when you finish From an iron bar placed in the fire.
The other end soon The gel is hot because Ihe transfers heat from one end From iron to the other end through conduction ((molecule rom to molecule). COl / vce / ioll is a process Heat broadcasting by movement Hot Article (rom one place to another) Thus plnce takes in liquids and gases. room
It is heated by convection by circulating the medium Air across the room. This brings us to mdillliOIl.

h gain over 93 million miles from area. When a cloud passes between the sun and the boat
Land. The temperature at this point decreases or decreases [ This is what happens when heat travels or is radiated by waves.



Chapter 4-fluid sensing


Throughout this chapter, you will explore liquid sensors. Another very important and important aspect

That can detect as soon as possible The signs of raindrops will allow you some precious 10 moments roll up your car windows or bring your own Laundry. When used as part of a weather data set Tion.

Which can be used to determine the amount of ice The fuel or water is left in a container or tank. 
weather Fans will also learn how to build moisture. 
Measure the heme around your home or store. Novice scientists will learn pH and how to build
And use a pH scale with easy positioning. Low cost the ingredients. Readers - nature and ecologists
You will learn how to create and use a stream. Levcl to measure the river's water
