APES 9/30 & 10/1 GET A COMPUTER!
Learning Targets I can analyze and communicate the effect of salinity on seed germination. I can use my math skills to calculate the volume of water run-off in a fictitious parking lot and research sources and consequences of run-off.
Soil Salinization Lab 1. Testable Question including MV and RV 2. Hypothesis 3. Procedure detailed enough that I could do it without help 4. Data table 5. Graphical representation of effect of soil salinity on seed germination (bar, line- whatever you like) 6. CLEVR conclusion Claim = what was your hypothesis? Was it correct? Evidence = at least 2 pieces of data to support your claim Reasoning = why did your data turn out this way? (i.e. why would certain salinities affect seed germination in the way they did?)
Add to your lab… Find another group that experimented on the same seed type as you did. Add their data as a second trial Add an average % germination to your data table
Conclusion Writing MY prediction: CL, EV will be easy-ish for you. R(easoning) will be harder Background: How do plant cells work, generally? Osmosis Why a high salt concentration outside a plant cell will stop seeds from germinating
Soil Salinization Lab Read the requirements I went over carefully Submit your lab as one group Google doc by Sunday at noon. Include all group member’s names
AP Exam Info. – add to notes 60% of test = 100 MC Questions (90 minutes) 40% of test = 4 FRQs (90 minutes) FRQ #1: Always a “Data Base Question”- a document is provided to analyze. Could be an article, set of data, graph, etc. FRQ #2: Always a math-based question FRQ #3-4: General knowledge (not data base or math-based)
Free Response Tips Be concise and answer the prompt only! Flowery language doesn’t help. Do not use bullet points- must be in essay form. Don’t restate the question in your answer. Keep sections of your answer separate Ex: a: ______________________________________ b: ________________________________________ If the questions asks for 2 examples, only the first two you give will be scored. If later in your answer you provide the right answer, too bad Answer the easiest parts first! Your answers can be out of order, as long as they are marked!
Free Response Practice #1 Do this question on a separate piece of paper You will need to use the book to research information for parts a, e, and f Next time, you will put it in a folder (provided by me), scored and stapled to the prompt. These will stay in class and be used for review later.
Math Review (30 minutes) Today’s Goal: Get through problem 55! Ask me for help if you need it. OR: Start the Chapter 2 Reading Assignment.
Due Next Time Complete the Chapter 2 study guide in your lab book. Bring a 2L bottle. The FRQ is not homework. Leave it here! Reminder: test corrections and retakes need to be done today by 3:45!
