Susan E Sandusky 6 th grade Teacher Booth-Fickett Math/Science Magnet School Tucson, AZ Lesson Plan Title : Cheek Cells Concept / Topic To Teach : Focus on animal cells by having students look at cheek cells through a microscope on an interactive white board. Standards Addressed: Arizona Science Standards: S6-S4C1-PO3- Describe the function of each of the following cell parts: • Cell wall • Cell membrane • Nucleus S6-S4C1-PO4-PO 4. Differentiate between plant and animal cells. General Goal(s ): Students will look at an animal cell under a microscope. Specific Objectives : Students will be able to: Identify cell wall, cell membrane, and nucleus of an animal cell. Required Materials: Microscope Slides Cover slips Methane Blue Toothpicks Gloves Dropper bottle Interactive white board Document camera Appropriate cords for listed technology Microscope attachment for document camera Rubbing alcohol Anticipatory Set (Lead-In ): On the students’ mindset, have questions related to cells (i.e. review questions from the previous lesson), Microscope care and usage procedures, etc. With the microscope on your desk, students will generally be curious and ask about what they’ll be doing that day. Also in students view: slides, slide cover slips, and the toothpicks. Step-By-Step Procedures: *Before beginning the demonstration, make sure to emphasize that this is only a demonstration and that the students won’t actually be performing this activity themselves. * Before the demonstration, put ¼ cup of Methane Blue into a dropper bottle so it’s easier to handle when it’s needed. Be very careful with the Methane Blue because it will stain anything that it comes in contact with. Also, attach the document camera to your interactive while board projector so it can be seen on the board. First, familiarize the students with the materials required for the demonstration and, if needed, the purpose of the material (i.e. Methane Blue). You will then put on the gloves. Using the document camera, you will place a slide under the camera. Using the Methane Blue dropper bottle, you will place 1-2 drops on the slide. Then, you’ll take a clean toothpick from your work area and scrape it on the inside of your cheek 5-6 times. After scraping your cheek, take the toothpick and stir it in the Methane Blue you had previously put on your slide for about 1 minute. After stirring, throw your toothpick away. Next, take a cover slip and, under the document camera, put it on the slide. Once your slide is complete, you will use your document camera and microscope attachment to view your slide. With your slide in focus, have students observe the slide and record it in their Science notebooks. Next, ask students if they can see any of the cell parts. If they can, they can (one at a time) come up to the board and point it out for the class. If they can’t see it, then ask why they can’t see it. Once you’re done with your slide,

you will wash it in the sink and then use rubbing alcohol to disinfect the slide and cover slip. If you have enough slides available for future investigations, then you can throw your slide and cover slip away.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
