Homework for Class 3
In class, we covered everything the students will need in order to finish the Tree Project.
We identified the trees to the best of my ability while only looking at the leaves. I cannot be confident about my identification because I couldn't see the size/shape of the tree or the arrangement of leaves on the branches. Feel free to research and correct any of my identifications.
We covered how to estimate the size of a leaf using graph paper. 5 sheets of graph paper were provided.
We covered how to estimate the circumference of a tree by wrapping a cord around it then laying the cord flat and measuring it with a measuring tape. (You can also use a fabric measuring tape if you have one.)
We covered how to estimate the canopy of a tree (instructions handed out and attached below). 5 more sheets of graph paper were provided.
We covered how to estimate the height of a tree (another method is in the handout attached below).
Homework: Complete 1 worksheet for the Tree Project (handed out in class and attached below). You may use the student's sketch of the tree from last week for item 10 on the worksheet or choose a different tree. Note: The student should not do more than 1 tree before next class because I want to make sure they are doing it right before they go on. If the student is not able to complete it due to extraneous circumstances, please email me before our next class.
Homework for Class 2
Sorry this is a little late! We had a great class yesterday, the students behaved amazingly well and we had fun talking about the big picture plan for the semester and the basic anatomy of bacteria.
I passed out syllabuses in class, and it is attached below in case it gets lost.
This semester has several projects:
Tree Identification Project: Beginning now, due October 7. By the end of the project, the student will have collected data on 5 trees of different types. As they learn how to collect information in class (like estimating the height, trunk circumference, canopy circumference, etc) they will collect that data on their trees throughout the week as homework. For now, they just need to collect one leaf from each tree (5 leaves overall). The trees should be close to home (even in the yard) so the student can easily visit them and collect data.
Bird Identification Project: Beginning November 4, due December 9. I will provide information on this project on November 4.
Insect Collection Project: Beginning September 16, due next semester. I will provide more information on this project next week.
Homework: There are two bits of homework for this week:
1) Select 5 trees for your Tree Project and bring a leaf from each tree to next class so we can (hopefully) identify the tree. They must be five different types of trees, and they should be fairly isolated from other trees with their branches not overlapping too much with other trees.
2) Use your sketchbook and a gray pencil to sketch any 1 plant. Focus on details like leaf shape, veins, bark texture, etc, and don't distract yourself by adding color. Don't spend more than 30 minutes unless you want to keep going.
Anatomy of Bacteria (Lecture Notes)
Bacteria are the simplest form of life. They are made of a single cell, with relatively few organelles (which is the organ of a cell). They have a tail-like organ called a flagellum which spins like a fan to move them through fluids. The rest of the bacteria is encased in a cell wall which projects them, gives them their shape, and allows food and oxygen inside the cell (because they don't have a mouth). Inside the cell wall, bacteria have ribosomes (which make proteins), DNA (which is like the recipe for proteins), All these organelles float in cytoplasm, which is a gel-like fluid filling the cell. Below is a picture with a bit more detail.
