Answer and Explanation:
I was only twelve. The gymnasium seemed so big, but this time it did not intimidate me. This one as well as others had intimidated me for weeks, but now I had conquered them. It had been my very first time competing in a volleyball tournament for my school, and we had won. All the nervousness and anxiety, all that yelling from the coach and teammates had been worth it. We lined up, side by side, facing the seats. My mother and younger brother were there, smiling, happy to see me happy. My mother had made a point of driving me to every single game and watching them to the very end. Somehow, it felt as if the medal I was about to receive was hers as much as it was mine.
All of a sudden, her presence was made even more important. Someone had the idea of inviting the parents onto the court to place the medals around our eager necks. No one else’s parents were there; at least for my team. I was sorry for them, but there she came. She was now everyone’s mother, giving each of my teammates their respective medals and a congratulatory hug. We were all her children for a moment, and sharing my mother had never made me happier.
NOTE: I based this in my real-life experience. Feel free to change anything in order to adapt it to your life.
Answer:
In their House of Sound, Fran Scott and Greg Foot investigate how drums work.
Drums have been around for thousands of years and throughout history have often been involved in warfare -something they are reminded of as they play along to Mars from Holst’s The Planets suite.
Using confetti placed on a drum they use a slow motion camera to reveal how the confetti behaves like air molecules when the drum is struck.
The skin of the drum vibrates and makes the confetti dance.
As the air molecules vibrate against each other, sound waves are formed and the sound of the drums can be heard.
Fran explains that the pitch of a drum depends on how tight its skin is. If the skin is tight the drum makes a high note, if it is slack it makes a low note.
Greg points out the amount of air inside a drum also influences its pitch. The more air in a drum, the lower the note. The less air in a drum, the higher the note.
Volume depends on the size of the vibrations that are made.
Hit a drum hard and this makes big vibrations and a loud sound.
Hit a drum softly and the vibrations are smaller and the sound not as loud.
Together they make a drum kit out of things that can be found around the house, and Fran shows us how to make fun drums out of a plastic bowl and half a balloon.

According to Webster Dictionary, Homeostasis is a relatively stable state of equilibrium or a tendency toward such a state between the different but interdependent elements or groups of elements of an organism, population, or group.
In simpler words, homeostasis is a period in time where things are relatively balanced and able to adapt to change without causing a lot of problems. I found a few examples involving the human body including body temperature, glucose levels and fluid volume. If you need an extra explanation, I will link the site if examples down below. (:
