BI 101 Fall 2018 Monday Oct. 8 2018 5:00 p.m. 131 Weniger 1. Journals can be turned in early 2. Late Portfolio? Can be turned in to 131 Weniger either: (A) Monday Oct. 8 5:01 p.m. - Tuesday Oct. 9 12:00 p.m. (noon), 25% deduction or (B) Tuesday Oct. 9 12:01 p.m. - Wednesday Oct. 10 12:00 p.m. (noon), 50% deduction. Directions Biology Journal Volume I 1. Assemble the journal, instructions are on the inner front cover. 2. Some of the journal entries are done on your own, others require an in-class stamp. If you miss a stamped activity, you can make it up the following week in GTA office hours, EXCEPT the conifer I.D. (journal #2) and the GTA talk (journal #3). See those journals for additional information. 3. To receive credit, journal entries need to be appropriate for a multigenerational public environment. Minimize disruptive impact to other students, the community, organisms, and the environment. 4. Exercise safety on your science excursions. Be alert and travel with friends. Name: Have memorable new science experiences that change your perspectives about the world, & journal them for future personal reference. Lab #
If you find this journal, please contact: Grading Please leave this page blank for the graders. Each completed page (8 total) is worth 1.0 point each, 8.0 points total. - zero points are assigned to pages that did not have a required stamp (both pages of lichens & both pages of flowers to fruit) - deductions are taken on pages that are incomplete, have errors, or inappropriate content. Be alert and travel with friends Avoid potentially toxic organisms Minimize impact on the environment and others Page Title Points Comments 1 Warm-Up (/1.0 pt.) Instructions for journal assembly: 1.

Pressed Leaf Find a deciduous leaf, press, dry, & attach here www.arborday.org/trees/whattree/ Warm-Up Complete this page after assembling journal Journaling is a method of recording experiences that encourages focused observation for possible later reference. Today s Date: Weather: Today s To-Do List: (activities, assignments, etc.) Look around you & select one item in your environment to sketch. It can be a pen, a cup, a leaf, etc. Try capturing its outline, and label with words to describe color, size, & other key features. Tentative I.D. Location Date Collected By Notes Collect responsibly & avoid potentially toxic plants, BI 101 Outcome: use a combination of print journaling (this Biology Journal) and digital media posts to promote Wash hands after handling any organisms. and capture memorable science experiences. 8 1
Lichen Basics A lichen is a community of organisms, including the larger (mycosymbiont) that we see, and the microscopic or (photosymbionts) living inside that give the lichen a green, green-blue, yellow, orange, or even red color. Ant Observations Make a detailed drawing of two individual ants. Label what each ant is doing and any other details you observe. Individual Ant #1 Using the Microscope The on switch is on the front of the base, left side Look through the eye pieces and slowly move the focus knobs (back, right and left sides) Individual Ant #2 Give everyone a chance to locate their own view To share scopes, switch places with someone else, without moving the fragile equipment Total Magnification = eyepiece magnification x (times) objective magnification Total Magnification used for your drawing = x 2 7
Ant Observations Observe the ant enclosures is in the hall window of 127 Weniger. Date: Time: Make a loose sketch of two of the ant enclosures. Include ant tunnels, locations of ants, and any other general information about what you see. Ant Enclosure #1 Lichens 1. Locate both the mycosymbiont and the photosymbiont in the same microscopic view, which one is more likely to be green? Stamp 2. Draw both the mycosymbiont and the photosymbionts. Ant Enclosure #2 3. Label the fungus and the producers in your sketch. The fungal hyphae (hair-like structures are more likely to be clear or brown-gray. 6 3
Floral Anatomy Stamp Flowers to Fruits and Seeds In last week s activity you learned about flower structures. Sketch the lily flower provided and label: sepals, petals, stamens (filament and anther), and pistil (stigma, style, ovary). Sperm (found in a pollen grain) fertilizes an egg (found in the ovule), and the fertilized egg within the ovule develops into a seed. What female structure of the flower does the pollen grain land on? The pollen grain starts to germinate and produces a tube that sperm cells from the pollen grain can move through to get to eggs. Once the eggs are fertilized by sperm, seeds can start to develop within a fruit. Fold Journal Pages Here During fruit and seed development, there is often a stage where flower parts are still visible. Sketch a developing fruit. Label: ovules (becoming the seeds); fruit (growing from the ovary); stamen (flower s male reproductive parts, and stigma (top of the flower s female reproductive parts): 4 5
