Today in EPS I discussed chemical reactivity, and I used the element Fluorine as an example of a crazy reactive substance. Here is the video I mentioned. And the presenter’s hair is a comic bonus. Your welcome for that.
Pick one of the articles, read it and write a one-page review, telling me about the article, what you learned and how you felt about it (was it well written, was it boring, etc.) Turn the assignment in when we return to school.
Wow, and before you tell me the images are grainy, remember, this is from a probe we humans put around Saturn! Saturn’s northern and southern lights glow in red on the bottom and purple on top in visible light, according to Cassini photos.
This year marks 45 years since we put a human on the Moon, and 54 years since the first human orbited the Earth. How is this possible? In all my years of teaching, I have NEVER met a kid who thought the Sun went around the Earth, not one. Frankly, I doubt I’ve met many adults who thought that either (and like most folks, I’ve met some really dumb people). Anyone who doesn’t understand how the Earth orbits probably can’t blame it on our educational system. Certainly not in a state like Ohio where it has been taught since long before I was born. This is ignorance by choice.
