Early parent conferences: 5-9 before and after school. (Presenting at NSTA–type Frazier in keyword search under search events: http://www.nsta.org/conferences/schedule2.aspx?id=2018atl
Be prepared: Complete and up-to-date DSN. Partner Tree. Tree survey–Field study #1. Most interesting idea. Most challenging idea. Most interesting observation. Understanding of survey techniques. Understanding of search image acquisition. Understanding of classification and naming of living things. Understanding of Darwin’s basic ideas.
Each group check in with Dr. F
Finish tree survey
Campus Trees Science 7 Periods 1 and 3 Frazier 2017-2018
Finish partner tree research
- A Partner Tree Prevents “Plant Blindness”Please acquire and organize the following information.
- Scientific, common English and local names of the tree
- Information on how the tree got its names
- Location of your tree on campus–map and description
- Location of other specimens of your species on campus
- Total number of specimens of your tree species on campus
- Description of key features of your partner tree (height/diameter, leaf shape/size, arrangement, branching pattern, bark, fruit, flowers, etc.) Girth in cm at 1.5 meters above the ground OR just below where the trunk divides–give the height above the ground as well. Greatest spread of canopy in meters. Approximate area shaded by canopy (directly under the tree) in square meters.
- Pictures of your tree, its flowers, fruits, bark and leaves over the course of the year and examples of other specimens of the same species,
- Leaf rubbing showing venation
- Bark rubbing
- Line drawings showing various structures and details of your tree (specimen and/or species)
- Use a stethoscope and “listen” to the tree. Describe any interesting sounds that come from the tree–not sounds from, say, scraping the stethoscope.
- Tell a secret to your partner tree. You do not have to record this in your DSN. Record it in your “heart.”
- What the tree is used for by humans? Furniture, medicine, fodder for livestock, ritual? What cultural or religious associations are there with the tree species? Dr. F may be able to give you a hint if you are stuck. Can you find a poem, story, novel, song, work of art associated with your tree species?
- What associations does the tree have with other organisms? Is it eaten by animals (host plant for butterfly or moth larvae, for example)? Dens or nests. Pollinators? Parasites? Fungi? Bacteria?
- How much oxygen would you estimate that your partner tree releases in a year? How could you / scientists make this estimate? How much carbon from carbon dioxide is taken up by your tree in a year? How could you / scientists make this estimate? How productive is your tree–if , for example, you could collect the fallen leaves every day for a month and get their dry weight, how much would you get–estimate–or make arrangements to do the experiment?
- What particular importance does the tree species have for science?
- Is it native or introduced? Native to the Delhi region? To India? To Asia? Introduced from where? If it was transferred, what can you find out about its introduction to India? If it is exotic (introduced), what is the extent of its invasiveness?
- References must be cited–full bibliographic information. (Note: You must have permission to use any photos that are not your own.)
Discuss summative–2 parts: Page on partner tree in specified format (to be included in pamphlet on campus trees; Interpretive questions on database of campus trees. Can we start on WED?
View, read, review the following links. What do you learn? What is your reaction?
