Cell Biology Part 2: Cell Transport Lesson Bundle

This unit includes 7 Lessons (50 minutes each) and 15 page printable work bundle. The Work Bundle has the students fill-in critical notes (red slides), conduct exciting hands-on activities about surface area, osmosis, diffusion, and active transport. Student's also answer questions, interpret graphs, includes games, built-in quizzes, and much more. The work bundles chronologically follow the detailed and interactive set of slideshows. A Quiz Game concludes for a great review and additional assessment. Answer keys, video links, crosswords, and much more are provided. Everything you need to run a fantastic learning experience is provided. Everything arrives in editable format if you want add in your own slides and activities, and the slideshows and work bundles can easily be converted into Google Slides / docs for friendly Google Classroom learning. This unit explores the Cell Wall, Cell Membrane, Surface Area, Diffusion, Osmosis, Passive and Active Transport. Please see the specifics about each part of this one of a kind learning experience.

Brief Descriptions

Lesson 1 Surface Area and Cell Membrane: The set lessons begins discussing ground beef vs a beef patty and time to cook. This gets the students understanding a bit about surface area form real work experience. A neat beet lab explores surface area. the lab uses beets cuts into sizes and placed in bleach. The beet pieces with the most surface area experience more discoloration from the bleach. Students make sketch and record info about surface area. This can be run as a demonstration if short on time and supplies. A slide describes the outcome that can be used if lab is skipped. Next, a gummy bear lab for two days from now is introduced so those can begin soaking. A teacher also sets up a dialysis tubing and corn syrup demonstration for the next day. Teacher also sets up several eggs to soak in vinegar for later in the unit. A slide in the slideshow describes what to do. Student's record the weight and size of the egg before soaking in their work bundle. Cytoplasm is described and supported by visuals and important red slides. As is the cell wall.

Lesson 2 Osmosis The Plasma membrane is then described in a series of slides with images and special focus is presented to the phospholipid bilayer and polarity. A journal questions asks the students to describe what a cell wants to let come in, and what a cell wants to keep out. The answers to these questions are presented in a step by step process. A lab for Osmosis is presented that has the students set-up, and as the students wait for reactions, they learn some important vocabulary and concepts. Directions for the set-up are provided. (Dialysis tubing, starch solution, and Iodine, Water, Clear Container). Students are introduced to diffusion as the teacher adds Iodine solution to the water. Diffusion is presented in a series of steps and teacher sprays some air fresher in a part of the room and students raise their hand when they smell it. This is always neat to watch how the particles spread out. A series of animated slides show how diffusion and the kinetic molecular theory are connected. Students then sketch a "close-up" drawing of the dialysis tubing membrane with molecules. A series of slides describe how the membrane is semi-permeable.

Lesson 3 Gummy Bear: Student's investigate their gummy bears that have been soaking and do a % calculation for increase in size. Students find that the Gummy Bear in the Saltwater has decreased in size.

Lesson 4 Extensions: Passive Transport is then described as well as osmosis. A step by step process describes what is happening in the lab at a molecular level. Throughout this process, students are encouraged to make notes about what is happening in their containers. Vocabulary such as permeable, semi-permeable, and impermeable are addressed. Teacher at the end of lab portion after the starch solution in the dialysis tubing has turned dark purple pocks dialysis tubing with dissection pin and students observe the starch reacting with the Iodine / diffusing through the solution. A series of follow-up questions with answers are provided. Hypotonic, Hypertonic, and Isotonic solutions are then described in a series of slides with neat visuals. Students then test their knowledge with a built-in quiz that has the students record if the solution is hypo, hyper, or isotonic based on the behavior of the cell. The answers are provided after the quiz. The question is previewed before the answer is revealed so the teacher can call upon students. A demonstration is provided (Teacher should plan in advance as the egg takes a few days) which has an egg placed in vinegar for several days. The students then observe the egg and answer a series of questions based on their understanding of solutions and osmosis.

Lesson 5 Active transport is then described in a series of slides including many animated slides. Students study an animated slide of the sodium potassium pump and try to recreate it using students as the molecules and transport proteins. This activity gets everyone involved and moving around. This is always a lot fun. Endocytosis is then explained in a step by step process and activity is included. A group of students holds hands (amoeba) and move across room and surround a few selected students who are stuck in place. The amoeba gets larger as it engulfs more students. Directions with visuals are provided. Pino and Phagocytosis are described. A series of challenge questions has the students demonstrate their understanding with many animated slides. Answers are provided in the next slide. The best note taking slide of the year has the
