with Leigh Ann Yoder Class OverviewAfter a brief introductory video and key concept review of microscopes, cells and cell parts, students rotated through stations learning about magnification and microscopes. At station 1 students had the opportunity to use hand held microscopes and magnifying glasses to examine various pieces of cloth and newsprint. At the second station students used a simple (or stereo) microscope to examine insects. At the third station they learned the proper parts and mechanics of a compound microscope as they examined a variety of slides. They also had the opportunity to view living organisms in a sample of stream water brought in by a fellow student. At the final station students completed section 1 of the Technology Lab: Build a Microscope found in the textbook pg 14. This final activity demonstrated the basic design concept of the compound microscope. Egg-sperimental ScienceNext, students were properly prepared for their first project: Egg-speriment with a Cell, found in their notebooks. As a class we reviewed the lab requirements, set up a timeline for completion, recorded data and began the project. *Note - each student came home with a glass mason jar containing their egg soaking in vinegar. As I mentioned before, this project will require just a little parent involvement. Students should be measuring their egg daily and changing the liquid. Unforgettable Cells!
HomeworkMandatory:
Project: Egg-speriment: Follow class instructions and timeline. Record measurements each day and change your liquid as directed. Read Section 1.3 Chemical Compounds in Cells Study Guide: Chemical Compounds in Cells Compounds in Foods (pg. 30 of text) Optional: Online Activity pg. 26 of Textbook Enrichment: Modeling Cell Structures (found in your notebook enrichment section) Comments are closed.
