Wednesday Wonderings: What Works?
I have been spending a lot of time cogitating, and basically spinning my wheels. I loved the way that Jana structured the final optics exploration: we self-assessed and then discussed our learning. Memorable for me was Jana’s description of how she decided to create shoebox cameras obscuras pretty much FIRST rather than last. The structure […]
Optics — Physics, Art and Fun!
Exploring the nature of light, and the way that vision works, today we explored a pinhole camera and a camera obscura. Questions to consider: What makes vision possible? How does light move? What is a reflection? What is refraction? What is a lens (hint: consider shape)? What is the difference between seeing something directly, and […]
Cozy Science
Got time to pull up a chair and have a spot of tea? Join me as we explore the wonderful world of science! There will be two main categories in this journal: optics (whole class activities) and measurement of force and motion. I am choosing the measurement because I know that can be a challenging […]
