Geologic Age Lab Report
Directions: Follow the procedure to simulate finding the half-life of an element.
Geologic Age
Geologists use radioactive elements to determine the absolute age of rocks. As
elements decay, they undergo radioactive decay, changing into daughter elements
and releasing energy. This happens at a set rate, and scientists can measure this
rate as the half-life of the element. Today, you will experiment with finding the halflife of a fictional element.
Materials • shoe box with lid
• 100 cubes (can be dice, sugar cubes, homemade cubes, Styrofoam, etc.)
• permanent marker
Procedure
1. The cubes represent the imaginary chemical element, Lokium.
2. Mark only one side of each cube with a permanent marker. If you are using
dice, you will focus on the dice that land with the 1 side facing up.
3. Place all 100 cubes into the shoebox.
4. Holding the lid tightly, turn the box over twice.
5. Remove the lid and take out the cubes that have the marked side up. If you
are using dice, take out the dice that landed with the 1 side facing up. These
cubes represent atoms that have decayed into the daughter element, DOL
(daughter of Lokium).
6. In the data table below, record the number of cubes removed and the
number of cubes remaining beside Trial 1. Do not put the cubes you removed
back into the box. Start again with the remaining number of cubes.
7. Repeat steps 4 to 6 until you have completed 12 trials, or until all the cubes
have been removed.
8. Now repeat the entire process from step 3, collecting data on the second
chart.
Data Collection
As you complete the experiment, take notes on what you observe.

1. After completing the data collection charts, construct a graph to represent
the data in each table. On the vertical axis, plot the number of cubes
remaining each time. On the horizontal axis, plot the trial numbers.
2. Connect the points you plotted. Draw a best fit line for these points. Use
the space below to draw your graphs or upload a picture of your graphs
using the image tool.
Data Analysis
Before drawing conclusions, you will need to look for patterns and trends in the
data. Write a paragraph describing the data and any patterns or trends you see in
your graphs of the half-life. Include the following in your paragraph:
• What is the half-life of the element Lokium?
• After which trial did you reach the half-life of Lokium, for each test?
• How do the graphs compare?
• What would you expect a third test to look like?
4
Drawing Conclusions
Having studied the data for patterns and trends, you should now be able to draw
some conclusions about how knowing the half-life of the element Lokium would
help you determine the absolute age of rock in which this element is found. In a
paragraph, create an imaginary example of finding a given amount of Lokium and
DOL in a rock, and then determining the absolute age of that rock. Assume that
each trial represents 1,000 years.

What is meant by Compound Subject ?
A compound subject is one that consists of two or more simple subjects. In other words, if a sentence's topic has two or more components, it is a compound subject.
Compound subjects help writers stay away from repetition. By employing a compound topic, a writer may say the same thing in one sentence as opposed to two.
When compared to repeatedly employing the same single subject, compound subjects are more effective and efficient. Using the same single subject in several sentences is seen as unsophisticated even if it is not incorrect grammar.

Answer: I went on an errand with a friend.
Explanation: I got picked up by a friend in his car at my home, the sun was shining and it had to be over 90 degrees. I had on a wide-brim hat . It was about 3:00 pm, and as I was waiting, for us to leave, his little dog was furiously wagging his little furry tail at me from the front seat.
I start talking "doggy" baby talk, to him and pet his soft fur, as, he licks my hand and smiles and makes noises like "Mmffff, mmmf"fff... (wag, wag ) as we are driving out of our area, 30 minutes later, we are near a beach, and my friend asks me, "Would you like to take a drive on the shore ?"
"I sure would " !!! I happily exclaim! ) We drive down the beach road, where you can see the water of the ocean where people are swimming, standing, playing volleyball, kids are frolicking, running all around the beach and then dart back into the water, on the sand, babies are laughing sitting half in the water and the parents and other adults look tired, exhausted with their sunburned faces and bodies.
So it is packed, (and it feels even hotter than when I left my area only 30 minutes ago), a throng of beachgoers, are all around us, as we slowly drive up the beach road, that leads back out to the main road and i half stare happily, at all the colorful and busy venues, (The last time I was here, was years ago when some of my friends were playing in one of the Beach clubs and I danced and danced that was a fun day.)And at all the sun-burned and tanned people.
".Boy that looks painful" "I say, out loud to my friend.
"Yes it does, " he says, as we slowly find the main road, and drive back on the highway to our destination another 30 minutes in the opposite direction.
1.Erosion is the process of materials moving from their source to another location through weathering. There are several types of erosion, but the most common types are erosion by wind, water, and ice.
Author's Purpose:
The removal of soil, rock, or dissolved material from one area on the Earth's crust and subsequent transport to another region, where it is deposited, is known as erosion. This activity is caused by surface processes (such as water movement or wind).
Erosion is the loss of soil and rock debris from the Earth's crust's surface, as well as the movement of the removed material by natural forces (such as wind or water). The term erosion's broadest definition includes general deterioration. Weathering is a static process, in contrast to erosion.
The process by which the Earth's surface ages is known as erosion. Natural forces like wind and glacier ice can create erosion. But anyone who has ever seen a photo of the Grand Canyon understands that when it comes to altering the Earth, nothing beats the slow, constant movement of water.

How did religion affect the lives of the Puritans?For the Puritans, living a morally pure life was essential. The Puritans lived lives characterized by their religious beliefs. The Puritans departed England because of the persecution they endured for their religious beliefs. Living decent lifestyles at that time in England was challenging for the Puritans.

Ch. 3 TGG what do we learn from nick’s judgment
Nick's judgment teaches a geographical entity with multiple regions that represent diverse sets of ideals rather than just as a country.
the required details about Nick's judgment is mentioned below
Nick views America as a geographical entity with multiple regions that represent diverse sets of ideals rather than just as a country.
The Great Gatsby's analysis
He feels that the East is more exciting and vibrant than the Midwest, which lacks the Midwest's moral core and appears dull and pedestrian in comparison. The Great Gatsby's characters—all Westerners, as Nick notes—are doomed to failure by this fundamental moral depravity. Nick finds the "quality of distortion" that draws them to the East repulsive, which influences his choice to return to Minnesota.
The fact that all of the main characters are Westerners, however, has another meaning. The West has been viewed as a land of opportunity and promise throughout American history, serving as the very symbol of those ideals. By maintaining a tight class system that excludes outsiders from its upper echelons, much like the feudal aristocracy that America had left behind, Tom and Daisy, along with other upper-class individuals, have compromised the democratic values that the country had vowed to uphold.
