Unit #1 – The Chemistry of Life 6th Edition – Ch. 2,3,4,5,6. Day 1 BIG IDEA 2: Biological systems utilize free energy and molecular building blocks to grow, to reproduce, and to maintain dynamic homeostasis. EK 2.A.3.b LO 2.6 The student is able to use calculated surface area-to-volume ratios to predict which cell(s) might eliminate wastes or procure nutrients faster by diffusion. SP 2.2 – The student can apply mathematical routines to quantities that describe natural phenomena. SP 2.3 - The student can estimate numerically quantities that describe natural phenomena. SP 3.1 - The student can pose scientific questions. SP 4.3 - The student can collect data to answer a particular scientific question. SP 5.1 - The student can analyze data to identify patterns or relationships. Activity Objective Intro – Leaf Lab The objective is this lab is severalfold: Firstly, it’s a nice first day activity instead of going over green sheets and stuff they do in every other class. Secondly, it allows them to organize themselves into groups on the first day. At the completion of the lab and write-up, my students are allowed to decide whether those groups are permanent for the year or given their only chance to switch. Materials Required Lots of random leaves of many different kinds. Walk around your neighborhood and/or campus and collect them. “Introduction to Measuring Leaf Lab 2012” handout. Time Notes One double period day. This lab is a nice starter. I really don’t give them much instruction on this. It asks for students to measure 20 different leaves, calculate surface area, make a data chart and construct some graphs. It neither says how to construct or label the data table nor the graphs; this is our chance for a nice learning opportunity in terms of, at the end when we’re assessing it, how to construct data tables and graphs and, very importantly, how to label them. It should all be constructed and labeled so that a random person picking up their notebook would understand what it’s talking about. It also has them come up with testable predictions at the end. This should also facilitate a good discussion regarding acceptable hypotheses. Day 2 Activity Objective Finish activity from previous day if needed. (I do NOT let lab notebooks leave the room, so students need extra time on occasion to finish.) Finish lab. After everyone is done with the lab, hand out “Standard Science Notebook Procedures 2012” paper. The main objective is not to make kids re-write a lab to be mean, however, this sets the tone for the entire school year regarding how their labs are to be written up. Re-do write-up accordingly. Materials Required Notebooks. “Standard Science Notebook Procedures 2012” handout. Time Notes One period. This is literally just giving them time to finish creating graphs and answering questions from the previous day. Give a strict time limit of the first hour of class though! One period. The consensus was that having the kids look at their own “free form” lab write up, then going over in class some things wrong with it (i.e. lack of thorough instructions, TOC, illustrations, data tables NOT labeled, graphs not labeled, pages not numbered, etc. would be beneficial to setting a standard for lab notebooks. This standard will carry them through to their college lab notebooks and into industry. Day 3 EK 4.A LO 4.17 - The student is able to analyze data to identify how molecular interactions affect structure and function. LO 4.22 - The student is able to construct explanations based on evidence of how variation in molecular units provides cells with a wider range of functions.

Background Info” Enzyme Lab Grading Rubric Enzyme Lab Prompt Jell-O packets or plain gelatin packets. Lactaid Pills. Milk of various types (I buy Half&Half all the way down to NonFat and even Silk). minutes official AP Lab #13 regarding enzymes. Students are given the handouts. We can certainly have much discussion in the room regarding expected outputs, i.e. creating a setup that will test lactose/lactase or the fruit proteases. The lab groups will definitely need time for whole class discussion, ingroup discussion and planning, then conferring with you in terms of their ideas (for approval or modification), then beginning their lab write-up. We can also use today to make some jello so it sets overnight, or to freeze any Lactaid or milk as per the students’ lab design. Day 11 SP 6.1 - The student can justify claims with evidence. SP 5.2 - The student can refine observations and measurements based on data analysis. SP 4.2 - The student can design a plan for collecting data to answer a particular scientific question.

Materials Required Those listed yesterday, plus hot plates. Time Notes 2 hours. This is the day for the students to finalize their lab plans (all lab groups should be doing a DIFFERENT lab in terms of independent variable) and test out their hypotheses. Today they should be focusing on testing and data acquisition. Since I don’t allow notebooks to be taken out of my classroom, tomorrow is for finalizing their write-ups, summaries, data tables, etc. Day 12 EK 2.A.2 - Organisms capture and store free energy for use in biological processes.
