View attached explanation and answer. Let me know if you have any questions.Hi dude,I am sending you the final version of your homework.Please insert your name on the figure (balloon) and don’t forget to put your name at the beginning of the page and Save as PDF :)You can also send me your name and I will write it on the balloon (this is required by your teacher) and sent you back.
The expansion of the universe activity
This is a practical demonstration that illustrates how the universe expands.
To submit a complete activity:
Collect the data following the experimental procedure.
Answer the questions
Attached a picture of your balloon that shows your name and the galaxies on the balloon
Once you have added all the information, save this document as pdf, name it as:
Name_lastname_universeassignment.pdf and submit it in CANVAS.
The universe is getting bigger and bigger. Astronomers believe that the universe is expanding – that all points in the
universe are getting farther apart all the time. It’s not that stars and galaxies are getting bigger; rather, the space
between all objects is expanding with time.
In the 1920s astronomer Edwin Hubble used the red shift of the spectra of stars and by carefully observing the light
from galaxies at different distances from Earth, he determined that the farther something was from Earth, the
faster it seemed to be moving away. This relationship has become known as Hubble’s Law, and it’s just one piece
of a bigger puzzle known as the Big Bang theory. Developed over many years and by many people, the theory
states that about 15 billion years ago the universe was compressed into an infinitely small space, known as the
primordial atom. It exploded in a sudden burst of energy and created a small, super dense, extremely hot universe
that began to expand in all directions. Over time things cooled, and tiny bits of matter clumped together to form
stars and galaxies. As a result of this explosion, all of these objects are still moving away from each other. In this
experiment, you’ll create a simple model to learn how the universe expands over time.

Ruler or tape measure
1) Inflate your balloon until it is about 10 cm in diameter, but do not tie the end.
2) Using the marker, make six dots on the balloon in widely scattered locations. Label one dot “home” and
the others A-E.
3) Using your tape measure (or string & ruler), determine the circumference of the balloon. Record the value
for the circumference in the table as “Balloon Circumference # 1=.”
4) Without letting air out of the balloon, use the string and a ruler to measure the distance from “home” to
each dot. Record the distances in table # 1.”…
