Natural Science - Year I

Unit 25: Microscopes and Cells

Preparation

• History Web Lecture: This is a rather long lecture, so students need to take their time to get through all of it. There are many details; have them read for the big picture: how is the development of this instrument driving and shaping the content of biology?
• Science Web Lecture: Our subject this time involves a lot of terms that may be new to the student. We will see these again next year when we discuss cell structures in the processes of photosynthesis and cellular respiration. The external site extends the information in the weblecture.
• Homework: This set of questions is pretty straightforward and should not be too difficult to grasp.
• Discussion: We will discuss the interaction of instruments and how they shape what we observe as we look at different kinds of modern microscopes used to explore cell structure.
