Engage in a stimulating biology lesson as we explore semipermeable membranes through a hands-on experiment. Gather necessary materials and complete the organelle foldable for homework. Work in groups to answer pre-lab questions and observe the interaction of oil and water. Document your observations and inferences to understand the properties of cell membranes. This lesson emphasizes critical thinking and collaborative learning while preparing for finals. Don't forget to finish your vocabulary flashcards and turn in your quizzes!

DO NOW: Answer Review Questions during Homework Check • FINALS REVIEW: What is an organelle? • Why do your fingers get wrinkly when they are in water for too long? • What is the picture on the right showing?
EXPLORE: Oil and Water Step 1) Answer your prelab questions with groups of 2-3 and get stamped so you can get started!! Step 2) Collect your materials (water in a beaker and a few drops of oil) and experiment with what happens when you combine oil and water. Step 3) Write down your observations and inferences.
Observations / Inferences Clean up Clock: Observations: What happened when you added oil to the water? Did it float or sink, mix or not mix? Include anything you saw. Inferences: Why do you think this happened? 2:00 1:49 1:50 1:51 1:52 1:53 1:55 1:48 1:56 1:57 1:58 1:59 1:54 1:46 1:45 1:47 1:44 1:43 1:42 1:41 1:40 1:39 1:38 1:37 1:36 1:35 1:34 1:33 1:32 1:30 1:02 1:29 1:28 1:27 1:26 1:25 1:24 1:23 1:22 1:21 1:20 1:19 1:18 1:17 1:16 1:15 1:14 1:13 1:12 1:11 1:10 1:09 1:08 1:07 1:06 1:05 1:04 1:03 1:31 0:59 0:28 1:01 0:56 0:55 0:54 0:53 0:52 0:51 0:50 0:49 0:48 0:47 0:46 0:45 0:43 0:58 0:42 0:41 0:40 0:39 0:38 0:37 0:36 0:35 0:34 0:33 0:32 0:31 0:57 0:30 2:00 0:44 0:27 0:26 0:25 0:24 0:23 0:22 0:21 0:20 0:19 0:18 0:17 0:16 0:15 0:14 0:13 0:12 0:11 0:10 0:09 0:08 0:07 0:06 0:05 0:04 0:03 0:02 0:01 End 0:29 1:00
This is why we don’t swell up when we go swimming. Cells let water out, not in!
Finals Review: Organelles Foldable ** Include all twelve organelles! Finish this for homework. ** Remind me to give you your quizzes back (they were great!)
