PSIWA Black Holes

This is a publicly shared DropBox folder that has copies of the slides and notes from the week.

CSATS is meant to be the portal into Penn State for all science teachers. They offer teacher professional development, research experiences for teachers, and are trying to maintain a comprehensive list of all of the STEM education and outreach programs going on at Penn State

Demonstrated by Glenn -- great resource for many, many topics in astronomy

As of 7/2013, the link is to version 4 of the book, updated in 2012. I don't see any dates in the manual itself, though, so I can't tell if the link below goes to the older version of the guide, or if they reset all of the links to point to this new version.

We would love to have everyone join PAESTA -- it's free until 2012!

Looks like membership is still free. Great resource

Hi Folks. Sorry I am just posting this now -- I thought it was here already!

Link to Derek's files (Keynote, Powerpoint export, and movies) from his presentation

This is the one location that has every resource related to the Hubble Space Telescope, including images, videos, animations, interviews with astronomers, links to on-line activities, and more.

Audience: EducatorsGrades: 7-12 Many aspects of black holes can be understood by using simple algebra and pre-algebra skills. Use Black Hole Math as a classroom challenge activity, an assessment tool or an enrichment activity. The problems in this booklet investigate black hole science and mathematics concepts including parts of a simple black hole and calculating gravitational potential energy.

Remember that there are some important typos in this document! For problem page 1, they give the mass of the Earth incorrectly (it says 5.7 x 10^24 in one place). For problem page 2, they don't provide the radius of the Earth, and the answer to problem 7 is 0.0132 m, not 0.17 m. This suggests there are likely other typos, but we didn't check beyond problem page 2.

Here is the link to the book with the "How Much Energy is That" activity we did in class.

I can email it to you, if that is simple enough, although it is in Apple Keynote format, rather than PowerPoint. If you don't have access to Keynote (it is part of Apple's "iWork" package) I could also do the conversion to PPT, but that might not preserve the formatting.

That would be fabulous! Apple Keynote is fine. Thanks so much!

Niel mentioned that there is an on-line activity that you can do that leads you through using Hubble images to estimate the number of galaxies in the Universe. This is the link to this activity, I encourage you to try it out!

Question - I couldn't find an answer to this and thought you could help. Has anyone run calculations to see if black holes could form within a black hole?

Hi Terry. I think that if you refer to the notes on singularities this is partly answered. Niel recommended Lee Smolin's book -- "The Life of the Cosmos", and he discussed at least one idea from that book related to your question. I think the best answer is that it appears plausible that this could happen if black holes behave inside their horizons as described in Smolin's book. Ultimately though, we are prevented from seeing anything inside the horizon, so we have no way to tell!

This is worth listening to.

This is the Black Holes website from the Hubble Space Telescope group that I quickly demonstrated on Friday.

This is "bookmarking" website I send my students to. These are the most frequently used sites I use with my students in both physics and astronomy.
