Date/Time : Tth (10:30-12:00) Score:
Direction: Answer the questions precisely. Use this activity sheet as your answer sheet.
1. What is redshift, and what does it tell us about the universe?
- Redshift occurs when the light source is moving away from the observer or when the space
between the observer and the source is stretched.
- Redshift means the wavelength of the light that stretched, so the light seen as shifted
towards the red part of the spectrum or how the lights shifts towards shorter or longer
wavelength as object in space such as stars or galaxies move closer or further away from the
galaxies are the faster they're moving. The evidence that the universe is expanding comes with
something called the red-shift of light. Light travels to Earth from other galaxies as the light
from that galaxy gets closer to Earth, the distance between Earth and the galaxy increases,
which causes the wavelength of that light to get longer.
2. Identify and explain three or more pieces of evidence for the big bang theory.
- The whole univers is started with a giant explosion called big bang. Big Bang Theory
shows that the universe is extended from high density state.
* The pieces of evidence for big bang theory are;
> There are red shift of different galaxies which means that the univers is expanding

> Due to the expantion of the universe, some of the new elements are created like
hydrogen, deuteruim, (helluim was first discover in the sun), etc.
> Microwaves are detected by orbiting detectors.
3. How old is the universe, according to scientists?
- Scientist confirmed that the universe is 13.8 billion years old.
4. What did Galileo’s telescope reveal?
- In Galilieo's telescope he was able to look at the moon, discover the four satellites of
Jupiter, observe a supernova, verify the phases of Venus, and discover sunspots. His discoveries
proved the Copernican system which states that the earth and other planets revolve around the
sun. Prior to the Copernican system, it was held that the universe was geocentric, meaning the
sun revolved around the earth.
