The Sorcerer’s Apprentice, or Never Use a Formula You Don’t Understand
In my grade 10 Science class I recently gave my students an introductory microscope lab, and in my haste I used a “canned” lab from a textbook. Although there are some good activities in this lab, students are presented with … Continue reading
