Classification

flat =Classification of Trees= As communities grow and new houses are made, many look at wooded areas and decide that building in or near these areas are a good option. In order to really understand the value of this resource, we must consider the individual purpose of a specific tree. In this activity, you will research a specific tree and prepare the information about that tree. After the research is complete, the class will take a field walk and you will be responsible for sharing your information as we find each tree. Each student will be responsible for submitting their specific tree information to the class wiki page. You are responsible for knowing the information about all of the trees reviewed in class. A quiz on trees will follow.

Information to find

 * 1) Name
 * 2) Scientific name
 * 3) Other trees it is related to
 * 4) Deciduous or Coniferous
 * 5) If coniferous: Spruce, pine, or fir and how many needles in a bundle
 * 6) If deciduous: type of margin, simple or compound (pinnate or palmate), alternate or opposite leaves
 * 7) Give 3 distinguishing characteristics of the leaf and/or the tree
 * 8) Give a specific use of the tree (for wood or furniture is not the best answer)

Resources:
[]

1. How are trees important to other organisms? Give examples. 2. How are trees important to the cycling of materials in the biosphere? Discuss these. 3. How are trees important to our food and fiber system? Give examples. 4. Discuss how trees demonstrate all the characteristics of living things discussed in class.
 * Homework:**

=Leaf project=

=Characteristics of Woody Stems=

Complete the following using the twig provided in class.

1. Share your twig age as well as the growth for each year (distances between all bud scale scars) with the rest of your group. Is the growth each year the same? What factors would contribute to the different rates of growth of the twigs? 2. Make a drawing of how leaf scars would be on a branch if it were alternate, opposite, and whorled. 3. What type of tissue would be found inside the bundle scars (ask yourself what is the purpose of the bundle scars)? Why is this tissue needed for the life of the tree? 4. What is the purpose of a lenticel? Where are they located on the twig? 5. What is a node when referring to a branch?
 * Homework**:

= = =Monocot and dicot lab= Monocot and dicot lab rubric ==

1. What is a cotyledon? 2. What structure took up most of the space found inside of the seed? 3. Which of the characteristics of monocots and dicots that you researched in the pre-activity would be the best for classifying an unknown plant as a monocot or a ? Why would the one you chose be the best? 4. What two types of tissues are found in the vascular bundles? 5. What is meant by the term herbaceous?

=Food and Fiber System:= We use plant species to provide for both our food and fiber needs. As a class, we will research various grains and fibers that are used around the world. Find about where the grain/fiber originated, uses of the grain/fiber, and nutrition information (most other grains are more nutritious than the ones we use regularly) or care requirements (maybe there are none) of the fiber. What are the advantages of the grain/fiber and the disadvantages?

Use your google doc from your class to answer the homework.

1. Which fibers or fabrics seem to be the most difficult to care for? 2. Which fibers are made from nonrenewable resources? What are the characteristics of these fibers that make using them beneficial? 3. Which fibers do you prefer to have your clothing made from (you can include synthetic fibers like rayon, polyester, and spandex that are made from petroleum.)? Discuss why (advantages that are most important to you and maybe disadvantages that don't seem to matter.) 4. What are the top three grains used in the world? What other grains are used to replace these? 5. If you could try one of the grains that you have not heard about before, which would you try and why?
