Lab 9: Concept Map of Body Fluids

SmithJ — Wed, 30 Jul 2025 10:42:34 +0000

Lab 9
Concept Map of Body Fluids
Overview: You probably noticed that our current unit (Body Fluids) does not contain a “Lecture Notes” tab with a concept map.That is because you will be creating your own concept map related to body fluids for Lab 9!
Lab Expectations
For this assignment, you will developa comprehensive,computer-generated concept map of body fluid chemistry.This map should resemble the maps that I include in the “lecture notes” section of each of our units, and should feature what you believe are the most important details from our video links in this unit!
Please make sure your map is saved as a .jpg file!Questions?Just ask!
Concept Mapping Resources
Directions:Everyone should visit the first link to gain a general understanding of what concept mapping is, how to create a concept map, and the reasons for creating and using concept maps.Then, everyone will need to useconcept mapping software to use for this assignment, or use an online app.Two options are provided below (you only need to use one form of concept mapping software, not both!).
1.This is the software that I use to create our “lecture notes” maps.When you visit the following site, click on Downloaded and follow the instructions that appear.Pros and Cons:Some people say that this software is not as easy to use or as fancy as Inspiration concept mapping software.However, it is absolutely free — you may download it for free, with no time limit on its use!

2. Free Online App!Some of my former students have commented that SmartDraw, below, is easy to use.

Please reply to the following discussion. Participate in the discussion by asking a question, providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between two or more lines of reasoning in the discussion. Responses must consist of at least 130 words, do NOT repeat the same thing your classmate is saying.

Element: The first time I heard the term element in chemistry, it was in middle school science class, learning about pure substances and the periodic table. Many people use the term “element” to describe things such as forces of nature like wind, earth, water, or fire, such as shows like Avatar: The Last Airbender. Other times, the word element in everyday use could describe a pivotal piece of something, like my mom talking about needing “the element of surprise” so she could pull a joke on my dad. The definition in chemistry differs from everyday use, and in our textbook an element is defined as a pure substance that chemical changes cannot break can down into simpler substances. This term will help us within this course to understand the building blocks of our world, and allow us to see how chemical changes affect these elements to create substances necessary to maintain life, such as oxygen, carbon, water, and more. The terms in everyday use and within the subject of chemistry are somewhat similar. Everyday use of the term defines it as something that is necessary or key to something; needing the “element” of surprise, or saying a book has the “elements” of a fantasy novel. However, in technical use the definition is more limited on what could actually be called an element, which is only pure substances that cannot be broken down any further. With previous knowledge added onto my learning from this chapter, I do not believe that the similarities or differences of these definitions will cause me to have difficulty with learning any concepts this course.
Density: I learned about density in elementary school, learning why certain objects like rubber ducks would float on water, versus objects like coins that would sink. Density is often used in everyday conversations to describe something as being thick or heavy. I would often hear my mom say something like “that pasta sauce is too dense for me”, meaning the sauce was too heavy for her taste. In our textbook, density is defined as a ratio of mass to volume for a substance or object. Within this course, density will help us to further understand the relationship between mass and volume, and will help us understand things such as anatomic weights, and why certain elements are more dense than others. The everyday term uses density or dense to describe something only as thick or slow, but the technical use of the term uses density to describe all levels of itself, from low density to high density. I do not foresee myself having issues with this term in understanding the course material as long as I remember density is not defined as just mass alone, but also in relationship to volume within chemistry.

Density is a term I have some prior knowledge on in regards to air density and the ideal gas law. This applies to my work as a Flight Nurse in regards to oxygen utilization and oxygen consumption of patients during air transport. The term density in Chapter 1 is defined as the ratio of the mass of sample of the substance (solids, liquids, gases) to its volume (mass/volume). An everyday example of density could be the relationship between ice and water. Ice floats because while it has a higher volume, it has a lower density. An everyday way I hear people utilize the word density would be people describing the weather/increased humidity as more, “dense.” To chemist, the term density can be applied to solids, liquids, gases as a unit of measurement. This relates to the course student learning outcome of explaining matter at the microscopic level because density in this context is broken down to its smallest quantification of weight by mass/volume. Some similarities between everyday use of the term are how we describe things in mass or quantification by density. This similarity impacts my learning of chemistry concepts by providing everyday context.
Molecule is a term I have prior knowledge of regarding two atoms being joined through a bond. I would say a common term people use in everyday life or language regarding molecules would be the description of water, which is a covalent bond. This comes to mind in casual conversation regarding hydration with water and even tying into salt consumption. The word molecule people often utilize to describe something small and compounded. The term molecule in Chapter 1 is defined as two or more atoms joined by a chemical bond. This term is technical to chemist as the basis of collections of pairs of atoms formed together. This relates to the course student learning outcome of explaining matter at the microscopic level as molecules are quite literally a main concept of microscopic chemistry relating to bonds.

Discussion: History of America from the end of the American Revolution to 1865

SmithJ — Thu, 13 Oct 2022 10:40:31 +0000

2.) Discuss and analyze the history of America from the end of the American Revolution to 1865 from the perspective of a modern scholar interested in advancing the Native American perspective. How did the important events that occurred over this time period (including the War of 1812, U.S. Mexican War, Civil War, and Reconstruction period) directly affect Native Americans? You may also consider: 1) what changes occurred in white Americans perceptions of Native Americans and 2) how did the movement West affect Native Americans internally as well as externally? Be sure to discuss at least a few prominent Native American figures of the time and explain their impact on Native relations with the United States.
