The activity questions are shown in bold and your answers are presented in order below.
Pre-test for Life in Space
1:
Based on the information, is it probable that life outside of Earth can be found in our
lifetimes?
yes
2:
Explain your choice to question #1.
There is so much unknown about space anything is possible.
3:
How certain are you about your claim based on your explanation?
(3)
4:
Explain what influenced your certainty rating.
I am still in between. I think some type of life will be discovered one day but not human life.
5:
Can life similar to that on Earth exist on Athena?
no
6:
Explain what might influence whether or not life can exist on Athena.
I think there is too much carbon dioxide for life to exist there.
7:
How certain are you about your claim based on your explanation?
(3)
8:
Explain what influenced your certainty rating.
Carbon dioxide is dangerous to us so I think it would prevent growth of other things.
9:
Based on the graphs, is there a planet orbiting this star?
no
10:
Explain your answer.
I have no idea
11:
How certain are you about your claim based on your explanation?
(1) Not at all certain
12:
Explain what influenced your certainty rating.
I do not understand the question or the graph.
13:
The graphs on the left show the velocity over time for four stars (A, B, C, and D) with
respect to Earth's position.Which velocity graph indicates a single planet orbiting a distant star?
Graph B
14:
When viewed from Earth, the light from very distant galaxies shows a red shift.Which
statement is supported by this evidence?This is evidence that these distant galaxies are
moving toward Earth.
15:
Scientists studying a Sun-like star named Ogle-Tr-3 discovered a planet that is, on average,
3.5 million kilometers away from the star's surface. The planet was discovered as a result of
observing a cyclic decrease in the brightness of Ogle-Tr-3 every 28.5 hours. The changing
brightness is the result of the planet blocking some of the starlight when it is between Ogle-Tr-3
and Earth.The planet was discovered when it passed between Earth and the star Ogle-Tr-
3.Which event in our solar system results from a similar type of alignment of the Moon between
Earth and the Sun?
solar eclipse
16:
The graphs on the left show the light intensity over time for four stars (E, F, G, and H) that
are visible from Earth.Which light intensity graph indicates a single planet orbiting a distant star?
Graph G
17:
The diagram below represents the bright-line spectrum for an element. The spectrum of
the same element observed in the light from a distant star is shown below. What does the shift
in spectral lines indicate? The shift in spectral lines indicates that the star is moving
toward Earth.
18:
The image below shows a spectrograph of a distant planet's atmosphere. What might a
scientist be able to learn about the planet from looking at its spectral emissions?
The surface temperature
