READING & EVIDENCE IN SCIENCE Instructions: Read the following and then complete the Reading & Evidence Table, using evidence from the text & your own research. Make sure answers use your own words. The Electromagnetic Spectrum & Our Everyday Lives (KEEP LOOKING BELOW) In our everyday lives, we use various applications of the electromagnetic spectrum without even realizing it! For starters, think about how we stay connected with our friends and family through our cell phones. These handy devices use radio waves to transmit our calls and messages, allowing us to communicate over long distances. Not only that, but radio waves also bring us our favorite tunes through radio stations. Moving on to something closer to home, consider how we use microwaves to heat up our food quickly and efficiently. Microwaves, a type of electromagnetic wave, vibrate water molecules in our food, generating heat and making our meals ready to eat in no time. Additionally, when it comes to our entertainment, television broadcasts rely on electromagnetic waves, like infrared and visible light, to deliver colorful images and sound to our screens. Even further, X-rays, which are another type of electromagnetic wave, help doctors see inside our bodies, aiding in diagnosing injuries or illnesses. As you can see, the applications of the electromagnetic spectrum are all around us, making our lives easier, more enjoyable, and even helping to keep us healthy!

VII. Reading & Evidence Table:
Part 1: Part of Electromagnetic Spectrum (Radio, Microwaves, Infrared, Visible, Ultraviolet, X-Ray, Gamma Ray)
Part 2: Frequency (Hz) (Found in the Image of the Text)
Part 3:Energy Level (Put either Lowest, Low, Highest, High/Anything above 1015 for Hz is high)
Part 4: Practical Use-List 2
Reading & Evidence Table:
Part 1: Part of Electromagnetic Spectrum | Part 2: Frequency (Hz) | Part 3: Energy Level | Part 4: Practical Use
Radio | Low frequency (10^3 - 10^9 Hz) | Low energy level | Transmitting calls and messages, radio stations
Microwaves | Low to high frequency (10^9 - 10^12 Hz) | Low to high energy level | Heating up food quickly and efficiently
Infrared | Low to high frequency (10^12 - 10^14 Hz) | Low to high energy level | Remote controls, night vision, thermal imaging
Visible | Moderate frequency (10^14 - 10^15 Hz) | Moderate energy level | Colorful images in television broadcasts, human vision
Ultraviolet | High frequency (10^15 - 10^17 Hz) | High energy level | Sterilization, tanning beds, fluorescent lamps
X-Ray | Very high frequency (10^17 - 10^19 Hz) | Very high energy level | Medical imaging, security screening
Gamma Ray | Highest frequency (>10^19 Hz) | Highest energy level | Cancer treatment, material testing
Note: Frequencies and energy levels are approximate ranges and can vary depending on the source.
