Abstract
For many years detectives and police officers had to rely on forensic science to identify how the victim die by using evidences like plant materials. So in this lab the purpose of this experiment is to identify how the victim died by using the evidence (seeds) that were given in this lab. In order to find the cause of the victim death you would have to compare the two different type of seeds Victim seeds and Suspect seeds by size, length and depth. As a result the victim has been murder by Bobby Walden because the average seeds size found on the victim and

in Bobby Walden house matches up also the seeds are bigger than normal sunflower seed that would be feed to the birds, therefore the cause of death is Bobby Walden.
Introduction
In this experiment the police department collected around 50 seed on the victim (Roger Peterson) and 50 seeds in the suspect home (Bobby Walden). What the police department reported is that Roger T. Peterson was going to feed the birds’ sunflower seeds from the birdfeeder at the back of his store and then Roger Peterson was found dead under a birch tree, also the police reported that the type of birds outside of Mr. Peterson store are Cardinals and Blue jays. (S. rush, Fall lab Manual 2014, p. 54).The purpose of this experiment is to identify the cause of death of Roger Peterson by measuring the size, length and the depth of the seeds that the police department collected, by measuring the seeds it will help us identified if the seeds were from Bobby Walden or from the store. “The largest seeds are used for human consumption while the smaller seeds are used for pet food” (S. rush, Fall lab Manual 2014,

p. 55). During this experiment the 5 benches in the lab will be split up into two group, one group will measuring the ten seeds from the suspect home and the other group will measure the ten seeds found near the victim, by measuring the seeds and calculating the average of the victim and suspects seeds the death of Roger Peterson can be determine if Bobby Walden killed Roger if the seeds from the crime matches the seeds at Bobby home(Bigger seeds Striped sun floor seeds) or if the death was accidental (smaller seeds Black oil seeds) . So if the average seeds size from Rogers Peterson body matches with the seeds found in Bobby Walden it will prove that Bobby Walden is the murder because striped sun flower seeds (human can consumed) but if the average for both seeds don’t match each other it will prove the death of Roger Peterson was accidental because the seeds are Black oil sun flower seeds (Pet/wildlife can consumed). Materials and methods During this experiment each bench will be divide into two groups, one group is going to measure the suspect seeds and the other group will measure the victim seed. When measuring the seed you need to measure the size, length, weight and the depth of the seed, after measuring the seeds take down the data that was collected from the experiment and submit it to the TA who will post the all data from the partial on blackboard in a excel file. After collecting the data go on to blackboard calculate the Average and the standard deviation on excel and finish the Formal lab report. (S. rush, Fall lab Manual 2014, p. 57) Results During this experiment the results show that the seeds do match each other but only in the average weight, width, length and depth graph. In the suspect/victim seed graph each group measurement had really similar numbers but in the Average volume suspect/victim graph test 1 and 5 had the exact same number but test 2-4 was extremely off from each other for example test 2 is volume average for the victim is 344.97mm compare to test 2 volume which is 239.52mm.With these extremely off values in the volume average the result still show that the cause of death of Roger Peterson is Bobby Walden due to the fact that all the 50 seeds from Bobby Walden house matches the same Weight, length, width and depth from the backyard of Roger Peterson. At the end through the results and calculations the cause of death of Roger Peterson is Bobby walden. Figure 1 Suspect/ victim seeds average (weight, width, length and depth) Figure 2and 3 is the average volume of the victim/suspect seeds Discussion In conclusion the result show that the cause of death of Roger Peterson is Bobby Walden, here are the reason why all the results point the cause of death to Bobby Walden. 1. When measuring the seeds found on Roger Peterson body by the weight, length, width and depth all the seeds were similar to the seeds found in Bobby Walden house so the cause of Roger Peterson is not accidental because human consume seed (Striped sunflower seeds) are much bigger than the seeds that would normally be feed to birds (Black oil seeds) (S. rush, Fall lab Manual 2014, p. 55). 2. The other reason why all the results point to Bobby Walden is because birds like the Cardinals and blue jays found in Roger Peterson back yard doesn’t consume any seeds because of their beak size. The Cardinals have a cracker beak which can only eat seeds with a softer shell like Black oil seeds because the Black oil seeds have a much softer shell compare to the Striped Sunflower seeds which human can consume, the Blue jays have a tweezers beak so it can only consume weak shell seeds and insects. At the end because of these two reason this is why the death of Roger Peterson is cause by Bobby Walden is because all the seeds on Roger Peterson body matches the same weight, length, width, and size also the type of seeds found on Roger Peterson can only be consume by human being (Striped Sunflower) because of its hard shell compare to the softer shell that which the birds can consume (Black oil sunflower seeds).

Forensic Science Introduction: Someone in a restaurant has suddenly fallen ill and a mystery powder has been discovered with the victim. As the chief investigator, your duty is to identify the mystery substance through a lab. In this lab, it will consist of five known compounds and one unknown compound. Your job is to distinguish which one out of the five substances is the mystery powder. To figure out the mystery matter you will have to compare their physical and chemical properties and match them with the appropriate compound.
The author of my essay is Simon Balic and he is a historian and culturologist. The title of the work is, Sunflower Symposium (109-111). Balic wrote this essay thirty years after The Sunflower was written. Balic argues that he does not forgive the sufferer, although he does feel some remorse. The author supports and develops the thesis in a chronological order in order to take the reader through exactly what was seen, heard, and thought of during this time. Both Weisenthal and Balic had a liable reason to not forgive the soldier, “There are crimes whose enormity cannot be measured. Rectifying a misdeed is a matter to be settled between the perpetrator and the victim” (Wiesenthal 54). Through this, Balic was trying to speak to his audience of fellow historians.
Simon Wiesenthal’s book The Sunflower: On the Possibilities and Limits of Forgiveness spoke to me about the question of forgiveness and repentance. Simon Wiesenthal was a Holocaust prisoner in a Nazi concentration camp during World War II. He experienced many brutal and uneasy experiences that no human being should experience in their lifetime and bear to live with it. Death, suffering, and despair were common to Simon Wiesenthal that he questioned his own religious faith because he asks why would his God allow the Holocaust happen to his people to be slaughter and not do anything to save them. During Simon Wiesenthal time as a Jewish Holocaust, Simon was invited to a military hospital where a dying Nazi SS officer wanted to have a conversation. The Nazi SS officer told Simon his story of his life and confesses to Simon of his horrific war crimes. Ultimately, the SS officer wanted forgiveness for what he done to Simon’s Jewish people. Simon Wiesenthal could not respond to his request, because he did not know what to do with a war criminal that participate in mass genocide to Simon’s people. Simon Wiesenthal lives throughout his life on asking the same crucial question, “What would I have done?” (Wiesenthal 98). If the readers would be on the exact situation as Simon was
We used wheatgrass were 40 wheatgrass seeds, two empty pots, soil, and water. We first added soil for both pots and 20 wheatgrass seeds in each pot. My partner and I decided that we label pot one experiment which is “sugar and water” and pot two control which is “water” only. The experiment was for almost four weeks we had to make sure both get the same room temperature and water, so we can see the results after this amount of time. Both pots had same room temperature so both can have the same amount of sunlight also, the same amount of water which is a glass of water from the sink once a week. In the experiment pot we added a glass of water with one teaspoon of sugar and the control pot glass of water. Every week we used to see both pots grow almost the same. At the end of the experiment, my partner and I measured the length for both plants and we recorded the average for each plant, so we can know the rate of growth
Thank you Mr. Wiesenthal for letting me be able to read and respond to your book The Sunflower. The Sunflower has showed me how ruthless it was for Jewish people in the Holocaust. In your book Karl, an SS solider, tries to get your forgiveness for the wrong he has done to the Jewish population. For a person to ask for forgiveness means that they have realized that they have done wrong and want to repent for their mistakes. The big question in your book was “What would you do?” I would’ve done exactly what you did I wouldn’t have granted the solider my forgiveness because he didn’t deserve it.
Seedfolks is a book about family. One day, a little Vietnamese girl named Kim plants some lima beans in a vacant lot in Cleveland to honor her father who was a farmer. A neighbor notices and decides to plant her own plants. Soon, more neighbors notice and do the same. Soon, the vacant lot turns into a community garden. The people of Cleveland have to avoid their differences and come together as a family to make it successful. The book Seedfolks implies that family is the true source of love because almost everybody in the book does something to express their love through the garden. The garden becomes somewhat like a family, and brings the community together.
Seed, a book by Lisa Heathfield, applies the idea that knowledge is power, but ignorance is bliss through the character development of Pearl, the deep descriptions of the settings and ambiguity of Pearl’s knowledge on certain scenes. Seed’s narrative quality explores that knowledge does not always make one influential, however, not acquiring knowledge means not feeling conflicted.
“Strange Fruit” by Billie Holiday conveys the inhumane, gory lynchings of African-Americans in the American South, and how this highly unnatural act had entrenched itself into the society and culture of the South, almost as if it were an agricultural crop. Although the song did not originate from Holiday, her first performance of it in 1939 in New York City and successive recording of the song became highly popular for their emotional power (“Strange fruit,” 2017). The lyrics in the song highlight the contrast between the natural beauty and apparent sophistication of the agricultural South with the brutal violence of lynchings. Holiday communicates these rather disturbing lyrics through a peculiarly serene vocal delivery, accompanied by a hymn-like

A Raisin in the Sun The creativity of Hansberry played a crucial role in the development of African-American drama since the Second World War. A Raisin in the Sun was the first play by an African-American author to be set on Broadway and was honored by the circle of New York theater critics. Drama of A Raisin in the Sun (1959) brought Hansberry to the Society of New York Critics Award as the best play of the year. A Raisin in the Sun shows the life of an ordinary African-American family who dreams of happiness and their desire to achieve their dream.
The research our experiment was founded on was that carried out by Taylor and Faust (1952). They carried out an experiment on 105 student’s, which was designed in the method of the game ‘twenty questions’. The students were split into teams of one member, two members and four members. They were then told that the experimenter would keep an object in mind whether it is animal vegetable or mineral was also stated, and they were then allowed 20 questions and guesses to reveal the identity of the object. In there experiment they found that the group of two members performed better than the group of four members in terms of how many guesses and questions it took them and how long it took them to deduce the identity of the object. However Taylor and Faust found that the efficiency did not differ in any significant way.
All dramatic productions feature the elements of drama. Following a viewing of the scene ‘Someone’s crying’ from the 1993 movie ‘The Secret Garden’ three of the elements of drama have been assessed. Role, character and relationships have been utilised in ‘The Secret Garden’ to create anxiety and suspense, enticing the viewer to solve the mysteries the Secret Garden presents. The protagonist in the scene is a young girl, around the age of ten who during the night leaves her room to explore her residence. The protagonist narrates the scene; she begins by stating that the ‘house seems dead like under a spell’. This makes the viewer anxious and fearful for the safety of our young protagonist. The protagonist is brave. She pushes open a door and
A girl walks down a busy hallway, bumping into another student. Her lips form the word “sorry” habitually, and the other student immediately nods, granting forgiveness with four words, “You’re good, no worries,” even though both people’s feet are still carrying them onto their destinations. Though a simple example, it is common. Due to the regularity and expectations to behave like these two individuals, the notion of forgiveness has greatly been devalued and misunderstood. Simon Wiesenthal attempts to enlighten the current society on the topic of forgiveness by sharing his story in The Sunflower and engaging the audience by challenging them to cogitate what they would have done if they were him. Wiesenthal successfully communicates the depth forgiveness embodies and examines differing perspectives concerning an

The sunflower got its name from its flower, which resembles the sun. The large flower is actually a mature flower head, composed a bunch of tiny flowers clumped together (Duncan 1975). The sunflower is an annual, erect, broadleaf plant. It has a tough, strong stem and rough simple leaves. The leaves on the immature buds are phototropic and follow the sun’s rays, one of the properties that increase light interception. The sunflower is not prone to many diseases, which make it appealing to producers (Duncan 1975). The plant grows rapidly and very large in the right location. They thrive in northern areas. One of the beneficial properties is the plants ability for phtytoremediation. It’s able to r...
