You know the one we showed the day I was absent…
Very well done. Sub atomic physics is really weird.
Today in EPS we spoke about entropy and the second law of thermodynamics. What if gravity was a function of entropy? this is pretty deep stuff, but interesting…
Here are the requirements for this quarter’s project options. Good Luck! The project is due when we get back from break.
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.
A not uncommon sight out west. Fun when it happens along the Pacific Coast Highway.
Still at it. What a great guy.
Here it is, any future such assignments will be posted here.
Blizzard Bag Lesson for Dynamic Earth
Go to the following Web sites from USA Today. Look at the graphic of Seasons and of Doppler Radar and complete the questions that follow. Turn the assignment in when we return to school.
Blizzard Bag Lesson for Earth / Physical Science
Instructor Chris Boch
Go to The Physical Science section of howstuffworks.com
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.
You fire a soccer ball at 50 mph out of the back of a pick-up truck doing 50 mph? I explain this each year in E.P.S. but now, thanks to Mythbusters, you can see for yourself.
To the observer on the side of the road, it appears as though the ball just drops, and it does, relative to that observer.
Here is the link to this week’s reading assignment. The article is on a new type of polymer plastic.
As you read, think about the following questions,
“Who developed the new material?”
“What can it do?”
“What is it good for? or Why is there a need?”
Looks like fun, and an excellent addition to any EPS Quarterly Portfolio.
Awesome! I forget who told me this in class (thank you Ramneet) but I am thrilled. I missed the second episode, but was able to watch it in HD on hulu. Here is the link for all three episodes so far….
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.
Okay, this makes me mad.
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.
The original press release is here…
Mars rover Curiosity snapped this photo of Earth (and the Moon) high in the Martian sky. You can see it much clearer in the larger size (click on the link). Humans can be amazing sometimes.
The BBC has created this infographic to illustrate some predictions on the far future. All the way to 100 trillion years from now. Not sure I buy a lot of it though.
Mass movement strikes! Amazingly, no one was hurt.
