Lesson Plan : Viral Models
Teacher Name: | Stephan/Bondies |
Grade: | Grade 9-10 |
Subject: | Science |
Topic: | Viruses and Bacteria Unit |
Content: | Helical, Spherical, Polyhedral shapes of viruses |
Goals: | Students will discover how the structure of a virus makes it an effective agent of infection |
Objectives: | 1. To learn that viruses occur in a variety of different shpaes. 2. To compare the structural properties of 3 different viruses. 3. To relate virus structure to viral infection of cells. |
Materials: | Intro and Dev-- Powerpoint, projector, models handout, premade model of "final product" for each station. Per Student-- Station 1:polyhedral pattern, 2" yarn, 12 cotton swabs, markers, glue gun Station 2:large ballon, small balloon, 2" yarn, "spikes" pattern Station 3:toiletpaper roll, 20 toothpicks, playdough, 8" yarn |
Introduction: | Powerpoint on various shapes of viruses we have discussed, including models and electon-microscope pics (Stephan) |
Development: | Review Model handout. Discuss the names and reasoning behind these names for each of the three shapes. Show and describe how each model is made. (Bondies) |
Practice: | Students are sent to labs in predetermined groups. On each lab table is a handout with instructions on making that particular model. Walk around to assist; may have to hand-over-hand (Stephan and Bondies) |
Accommodations: | Students may work with a partner assigned by the teacher to complete the write-up or the task. Because this is a hands-on activity, accomodations are limitless. |
Checking For Understanding: | The following day, an oral review is given over the shapes and how each model infects its host. |
Closure: | The students will use the information from this lab in a paper on a virus they each have chosen from a list. |
