GEOL 1208.1 learning journals

Question Description

Learning Journal

•Make an entry after each class. Notebook or computer.

•Think about what you have learned. What does it mean to you? Do not write a chronology of the class.

•As you reflect you will begin to see how you are learning and how you connect your learnings to your life to make sense to you.

Writing Learning Journal Entries :1.Purpose (#1): help you think more deeply about –

qWhat you are learning,

qWhat it means to you, and How it connects with your thoughts, life experiences, and/or the media

2.Purpose (#2): reflect and connect.

3.Purpose (#3): practice an ‘art-form’ that will add greater depth and enjoyment to your learning.

4.Purpose (#4): give powerful intellectual tools with critical thinking for success.

Basic Requirements for a Good Mark

•Have enough entries.2 to 5 are too few.Have more than 6.

•Length: 100 words to 1000. Your choice, depending on your interest.

•Use the pronoun “I” so I know you are ‘speaking.’ Think about what you are learning and what it means to you
•You may begin with what happened in class.Move onward in your writing to reflect on what this meant for you.

•One entry per class. Date each entry.

•Low marks (<12/20) for simply listing what happened in class.

Examples of Poor and good writing

We began the class with Dr. Howard telling us about the class.He then had trouble with the computer system.He asked us a question about cosmic dust.After that he talked about the models he brought to class.We listened to him tell us about nucleus and electrons and some of the forces. ……..

Class started with a problem of the computer working; Dr. Howard reflected that sometimes looking at the problem overall will offer a solution.I have begun to do this and it is surprising how many problems I can solve with this idea.Then he asked if we thought we were stardust.What a question! I talked with my group and we began to get an answer.We think we are stardust because we all came from the primal explosion. I had never considered this question.So I am thinking, what else haven’t I asked myself?………..

Final word on journals

•Journals are fun to write.

•They may have short entries but > 6 entries.

•Date each entry.

•They help you learn.

••Use reflection.

•Talk about how you connect your learnings to your life!

•Suggest ways you might apply your knowledge.

Forum 4: Biodiversity and Extinction

Question Description

We’ve recently discussed how new species arise and also how they end: the process of extinction. Recent research suggests that we may be in the middle of a sixth mass extinction event, in this case caused by humans.

The following articles deal with aspects of world biodiversity and extinctions. Read through at least two articles and draw from them in your posts and comments.

There Have Been Five Mass Extinction Events in Earth’s History. Now We’re Facing a Sixth (Washington Post) (Links to an external site.) Interview with Elizabeth Kolbert, author of the recent book The Sixth Extinction.

Mass amphibian extinctions globally caused by fungal disease (Links to an external site.) A third of all amphibian species are threatened with extinction.
(Links to an external site.)
New Madagascar conservation map protects maximum number of species in biodiversity hot spot (Links to an external site.). The island of Madagascar is home to thousands of rare species found nowhere else, including lemurs.
(Links to an external site.)

Climate Race Separates the Weeds from the Trees (Links to an external site.)(New Scientist). An interesting possible future trend is the rise of “weedy” species that flourish in disturbed environments and crowd out existing plants and animals.

This is a fairly open-ended forum. In your posts, please address two or more of the following. You can also draw from other sources you’ve read independently, or make other relevant comments on the topic of biodiversity and extinction.

  • Madagascar, Indonesia and the Amazon basin have some of the greatest numbers of different species concentrated in a single area. What kinds of environments do you think encourage greater biodiversity?
  • What are some examples of non-native “weedy” (hardy, easily adaptable) species of plants and animals that have entered North America and have caused or are starting to cause major problems for existing plant and animal (and human) communities?
  • How are humans and human activities contributing to extinctions of plants and animals?
  • Can humans realistically do anything to reverse these trends described in the articles? If so, what sacrifices (economic, demographic, etc) are we willing to make in order to preserve biodiversity?

Science lab pro

Question Description

Lab project 1

For each assignment, you will use the M.U.S.E. link to complete the lab.

In this lab, you will see the progression of industrialization and human growth. This will help you write a scientific paper that focuses on the sustainability of groundwater.

Human Impacts on the Sustainability of Groundwater

Sustainability is based on this simple principle:

  • Everything that is needed for human survival and well-being depends on the environment

Also, sustainability:

  • Creates and maintains conditions for humans and nature to exist in harmony
  • Helps fulfill the social and economic requirements of present and future generations

Keeping sustainability in mind, address the following in your scientific paper:

  • If current human growth stays the same, will groundwater sustainability be impacted?

Using the M.U.S.E. link, review the background information and gather your data.

SC235 General Biology – Human Perspectives

Question Description

***My assigned niche is “An Ecologist Studying Sloth Behavior in a Tropical Rainforest”***

This assignment is 750 words in APA format.

Where do we fit in?

This week you are exploring the characteristics of our species and the role we play in our ecosystem. Two terms commonly used to describe an organism’s place in the environment is their “habitat” and their “niche.” A habitat is defined as an area inhabited by particular species. A niche is defined as the role (job), activities and resources used by an organism. For example, a polar bear’s habitat is the arctic whereas its niche is to swim, eat fish, walruses and seals, and to take care of polar bear cubs. Have you ever considered the characteristics of your habitat and niche or thought about what might happen if you were forced to move and occupy another habitat, and switch to another niche? This Assignment will give you the opportunity to compare and contrast your current habitat and niche with an assigned niche (described below).

Your essay should include:

  • A description of your personal habitat and your assigned habitat highlighting the similarities and differences.
  • A description of your personal niche and of your assigned niche highlighting the similarities and differences.
  • Consider what characteristics would provide a survival advantage to you or to the individuals who currently occupy each niche and habitat.
  • How have humans adapted to the two habitats and niches?
  • What difficulties might you have living in the assigned niche and why?
  • What types of cultural adaptations have evolved from living in your niche? Your assigned niche? What are the benefits and challenges of these cultural adaptations?
  • Your discussion should consider any biological adaptations as well; things such as dealing with food spoilage, insect vector control, food and waterborne illnesses, etc.
  • Consider the organism you have been assigned to study in your assigned niche. Would you classify it as a biotic or an abiotic component of the environment? Explain your reasoning by applying the characteristics of life covered in Chapter One.
