LIVE Q&A Calls
Every Wednesday at 12 noon Pacific (3pm Eastern), we’ll be on the phone answering any questions you have about any part of this program. These Q&A calls are for folks on any level of the eScience program, whether at the beginning or with the more advanced stuff. We stay on the phone as long as there are questions to answer.
Here’s the phone number you need to dial in:

I have a video on how to do this in my summer e-Camp (which is posted here: http://www.sciencelearningspace.com/summer-camp/) It’s incredible to watch – it’s the fastest way to TP a house… or a kid!
How do you make TP fly over 30 feet???
You can permanently damage magnets if you heat them beyond their curie temperature (read more about what that is here: http://www.sciencelearningspace.com/2010/04/curie-heat-engine/ ), so if you burn them, chances are you’ve exceeded their upper temperature limit.
Hi Aurora
I just want to know why magnets doesn’t stick after burned.
Thanks!!
Yes, you’ll want to keep an eye on it since we’re ‘roasting’ the food and it can conceivably catch on fire and pose a hazard. Make sure you don’t leave this cooking unsupervised – it will cook within 5 minutes.
I just got a page magnifier and I am thinking of using it in the pizza box cooker instead of the saran wrap, Am I in danger of burning the box ?
Excellent question! We go into a lot of detail about that here in the Unit 11 content about where magnetism comes from and why iron works so well. When you rub a magnet along a nail, you’re lining up the domains to point all in one direction, but they don’t like to stay that way permanently (as you’ve found out). If an object is filled with atoms that have an abundance of electrons spinning in the same direction, and if those atoms are lined up in the same direction, that object will have a magnetic force. Check out this magnet experiment to help you understand what’s really going on.
Hi Aurora,
I was thinking about how you can magnetize metals by rubbing them against magnets (we just did the compass thing) in one direction, and I realized that the metal that you’ve magnetized, it’s magnetic field will eventually wear out. How come this doesn’t happen on the magnets you can buy at stores?

Wow. Good link. Thanks!

Hi Nathan,
Thanks for the correction – I’ll get that fixed on the quiz right away!
Our sun is not large enough to go supernova or even nova. Stars that go nova have a solar mas of at least 1.4 times the mass of our sun.
Hi Aurora,
We just took your intro to science test and found a problem. The answer to question 9 should be A,B,C, but it says the answer is A,B,D, which would tell you that the three primary colors of light are red, blue and yellow. And in question 24, you say that when you combine red and green together, you get yellow – which is correct, so I thought it was funny that your two questions contradicted each other because if yellow is a primary light color, then you can’t make it with red and green.
Also, I had a question about #2. I thought that our sun would become a supernova, and was sure I’d seen that in documentaries. So, if the sun turns into a hard black diamond about the size of the earth, does it not go super nova? Or is that a stage after supernova?
Thanks,
Nathan

Where can I find on the website how to shoot peas?
Thanks!

You can always send an email or ask a question here anytime. We’re happy to help!
why not on other days
Yes – we can talk this way… in the comment box. Otherwise, you pick up the phone (on Wednesdays).
Whatever works best for you.
can you talk on the computer
Hmmm… I don’t think we even record the Q&A calls, so there isn’t a transcript. However, you’re more than welcome to join in on the next one and ask about it!
But here’s how to see the IR beam.
Is there any place we can go to get transcripts of the previous calls? I would love to know the answers to shocking parents and seeing IR beams with my eyes. All of them, really. So awesome.
Yes, the same format where you call in around noon and I stay on the phone as long as there are questions. You can ask about anything to do with e-Science: how to get around the site, find a particular experiment, get info on unit that’s posted, or q’s about any experiment online. And you can expect to hear more secret experiment ideas during the call also like we did last year! (How to shock your parents with a lemon, how to shoot peas with a pencil, how to make TP fly over 30 feet, how to see IR beams with your eyes… cool stuff like that.) Talk to you soon!
Are these the same as last year’s call ins?
