Students use microscopes to observe single-celled organisms and to differentiate between plant and animal cells. Students extend this knowledge to consider health implications for themselves. Activities Using examples in the classroom, students brainstorm what they think is living and non-living.
Students record their observations with special attention to the shapes of cells.
Using Venn diagrams, students illustrate the similarities and differences between plant and animal cells. They observe the impact these micro-organisms have on the host. They discuss how some micro-organisms can spoil human food and how others can help make food or prevent disease. They demonstrate their scientific skills and processes through demonstrations and performance tasks. Skills and processes Students prepare a slide, view the slide using a microscope, and illustrate what they see.
