Lab 1- Introduction
Learning Objectives
Review lab structure and syllabus
Examine statements to identify objectives, hypotheses, and theories
Review simple algebra
Before starting on these questions, please introduce yourself on the discussion board, welcoming your classmates, and watch the two videos linked in iCollege. This first lab will introduce the scientific process and terms we frequently use in science that may be confusing, and review simple algebra. As you go, answer the questions below and answer question 2 in the PowerPoint
file. For most of the rest of the semester, you will be filling out Word documents and manipulating PowerPoint files to answer questions. Make sure you save your work on your own computer, the upload the completed assignments (Word and PowerPoint) to the correct assignment folder. Remember, throughout the semester, you are encouraged to study and work with your classmates. However, all assignments will be run through TurnItIn and students who are copying from classmates will face repercussions, as outline in the Academic Honesty section of the syllabus. We may ask you to Google the answer to the question or look up information online- once again, you should not directly copy anything from a website, but should instead put the answer into your own words (and include a link to the website you used).
1)
Explain the term “science” in your own words. (2 pts) The term science means a process that helps us learn more knowledge about where we live. Science to me is figuring out the what and the why. 2)
Complete PowerPoint matching activity. 3)
Make your own observations about something around you. It could be something in your house that is happening, something you see outside your window, something you remember seeing on campus last semester. For each observation, write a hypothesis about WHY the thing you observed happened. Finally, write and explanation of how you would test your hypothesis. Please do this for three observations. (9 pts)
1.
Drinks that I had outside busted open all over the ground. I think this happened due
to the current weather we’re going through. The very cold temperatures and harsh winds acted like a catalyst for the juice to burst. How I would go at testing this hypothesis is by doing it again I would take another bottle of Juice, place it outside and this time set up a camera to watch it burst and if it works my Hypothesis was right.
2.
My computer turned off on its own. A reason why this probably happened is because I was either idol from my laptop too long, someone turned it off or my laptop had
died. How I would go at testing is if it died, I would try to see if I can turn it back on if it doesn’t work then that hypothesis is true and I would just put it on the charger. Also, If I was to idol from my laptop then I would just touch a button to see if it turns back on. And If someone turned it off I would ask someone in my perimeter if they’d seen someone turn off my laptop. 3.
There was a large crowd of students standing outside on campus. A reason why this is probably happening is some type of event is going on campus. To see if this Hypothesis is true I would go outside myself to see what was going on If I saw tables flyers etc. I would find the source of what the students were all grouped up for. 4)
What is an example of something you have heard at some point in your life that is a hypothesis but was presented to you as a theory? (2 pts) Optimizing exposure to light in the workplace consistently leads to increased job satisfaction among employees. 5)
What is one scientific law you learned in high school or in any other science class? (2 pt)
Newton's Law of Universal Gravitation. Which I learned in high school physics 6)
This graph shows the weather on GSU campus from May 11, 2020. What was the temperature at
9 am? Make sure to include units! (2 pts) 56
°F.
7)
Does this graph represent observations or hypotheses? Why? (4 pts) It represents an observation because the temperatures aren’t predicted they’d already happened and were already graphed and recorded. A hypothesis is a prediction, and nothing was predicted.
8)
Using that same graph, make two more observations about the weather that day. (2 pts)
1.
Around the morning it was cold and eventually getting closer to noon the weather shifted and had a peak around 3 pm hitting about 70
°F
2.
And looking a the graph there was a lot of wind that day it was a high gust of wind specifically in a the early afternoon. 9)
Now, here is the weather from April 29, 2020. What do you observe was different from this day than May 11
th
? What is a hypothesis that would explain these observations? How would you test that hypothesis? (6 pts) Not only are the temperatures different but there also was a higher chance of precipitation during this day versus May 11
th
where there wasn’t any rain perceived on the graph. A hypothesis that would explain these observations would be that there is a lower chance of precipitation in May because May is a warmer month with lower humidity. We can test this by collecting, analyzing, and comparing both months for their temperature, humidity, and precipitation. 10) Use Google to investigate one scientific theory that interests you. It doesn’t have to be related to geology, but it can be! You should write a paragraph (about half a page, double
spaced) about the theory in your own words. Make sure to include: (1) a description of the theory, (2) at least one scientist who was part of the discovery of the theory, (3) the time period this theory was developed, and (4) two hypotheses of your own that would test this theory. Including links to all resources you used at the bottom of your paragraph.

Paragraphs that have not been proof-read or contain many grammatical mistakes will lose
points. (10 pts) (If you are struggling to come up with a theory, reach out to your TA and they can give you suggestions) A scientific theory that I’m still interested in would have to be the theory of evolution. The theory of evolution is the idea that aims to explain how organisms change or evolve over time due to their different environments. Many different individuals worked and published this theory but one that stands out and is used to teaching in many classes is none other than Charles Darwin and his partner Alfred Wallace. In 1858 they proposed that evolution occurs because of a phenomenon called natural selection which means organisms produce more offspring than can survive in their environment. So those of that offspring are better equipped to survive, grow to maturity, and reproduce. To sum it up Natural selection is the survival of the fittest. One hypothesis would be to put an animal in an environment different from their original and watch and spectate to see how it adapts, A second hypothesis would be to select multiple pairs of species with varying degrees of evolutionary relatedness. Once you do, you analyze their DNA and measure the genetic differences between them. Then compare the observed differences with the expected ones based on time since their divergence so you can observe the time frame for
evolution. Work Cited

Next, let’s review some simple algebra and unit conversions. If you need help, here are some resources:

conversion
Always show your work- it makes it possible to earn partial credit, even if your final answer is incorrect! And Google can help you with figuring out any unit conversions, like miles to km.
11) A car travels 5 miles in 20 minutes. How fast was it traveling (in miles/min) (2 pts)
V= x/t: V= 5mi/20min = 0.25
mi/min I used the formula for velocity, so displacement divided by change in time 12) How fast was it traveling (in mph) (2 pt)
There are 60 min is an hour so 60 x 0.25= 15mph 13) A car was traveling at 60 mph for 30 minutes. How far did it travel, in km? (3 pts)
First I must convert the time to hours 30min = 30/60 hours = 0.5 now I can look for the distance: 60 mph x 0.5 hours = 30 miles. 1mile = 1.609 30 miles x 1.609 km/mile = 48.27 kilometers 14) A stick is 0.5 m long. How long is it in inches? (2 pts) One meter is 39.3701 inches and to 0.5 m in inches we have to multiply 0.5 x 39.3701= 19.68505 inches 15) A rock has a surface area of 3 in
2
. What is the surface area in cm
2
? Remember: in
2
= in*in and both units need to be converted. (4 pts)
There are 6.4516 cm
2 in 1in
2 so to find the surface area in cm
2 you have to multiply your figure by 6.4516 3
in
2 x 6.4516 = 19.3548 cm
