Diigo web 2.0

Diigo is a web 2.0 (social network) site designed to share bookmarks and lists.  You may have noticed I used to use Delicious and fed my bookmarks to the sidebar of this blog.  I have found Diigo to be much easier to use and much more powerful.  Besides being able to bookmark and tag websites and feed links to the blog, I am able to create list lists for science subjects like Biology, Chemistry, Physics, Astronomy, Science Interactives, and so forth.  I can add notes to websites that others in my network can see when they visit.  I can even highlight and annotate part of a website and send that to others in the network.  I am also able to create groups, like the At Home Science group I made, to which members can contribute and be emailed the latest posts as they are added, or daily, or weekly.

Diigo also has a very hand toolbar for bookmarking, highlighting and annotating websites.  I have buttons that take me to my library website or displays links in a sidebar.  If the toolbar is too much, you can drag the Diigolet to your links toolbar, then click on it whenever you want to save a website to your Diigo.



If you decide to use Diigo, be sure to follow me and join the group to send and receive great science links.  If you don't join, feel free to browse my public library and lists.

Finding Darwin's God

Finding Darwin's God: A Scientist's Search for Common Ground Between God and Evolution (P.S.)Evolution, Creationism, Microevolution, Intelligent Design, Materialism, Science and Religion...where does one begin to understand what all controversy is about?  Start with Kenneth Miller's book, Finding Darwin's God.

Kenneth Miller is a Catholic cell biologist that clearly explains all of these subjects.  He begins by taking us through the volumes of evidence supporting Evolution, including the scientific meaning of "theory" that is often misused by opponents of Evolution.  He then gives the details of Creationism, Microevolution-only, and Intelligent Design, describing not only where these proposals are wrong based on the scientific evidence, but also where they are philosophically insufficient to explain God's relationship to His creation.

After showing the fallacies in these common challenges to Evolution, he continues on to a very important section detailing how scientists also misuse Evolution as a basis for a philosophy of religion in that it somehow proves that God does not exist.  He points out that scientists' vicious religious attacks are some of the reasons why Evolution has such passionate opponents. (He did not continue on with how a twisted interpretation of Evolution became the foundation of the horrid philosophy of Eugenics.)  He points out the hypocrisy in demeaning those who try to discount Evolution by distorting the science while giving a pass to those who also distort the science to apply it to philosophy and society.

Finally, he takes his readers through the scientific basis as to why Evolution does not mean that our lives, our choices, our futures are determined and predicted by our genetics.  He explains that, at the very core of all the ordered universe, we have found quantum chaos that impacts even how mutations occur. In other words, God has a role to play in our lives.

My sense is that Miller wrote this book for scientists and people like me--Catholics who understand the Unity of Truth and have no qualms with Evolution, but strongly reject Evolutionism.  He demonstrates that being a serious scientist and a serious Catholic is not a conflict.  He does not, however, get into any of the theology about where Evolution fits into God's plan; he does not discuss why there is something instead of nothing, and, frankly, that is much too big a question to address in this book.

In taking this approach, he sometimes oversimplifies an argument to the point where he puts it on theologically shaky ground.  For example, he says that evolution eventually created what God was looking for--creature that could know and love Him--undermining an All-Knowing God.  He also discusses free will by saying that it is impossible to create people with the option to sin that would never do so.  Technically, using a logic argument, it is highly unlikely that no one would sin ever but not impossible.

While the book is an excellent overview of this controversial topic, it does not discuss Evolution in light of Catholic religious philosophy or theology.  Finishing this book left me looking for a good follow up to fill in these areas.

I particularly took interest in the tale of Fr. Murphy, who told a very young Miller that a flower is a work of God, just like we are, because scientists don't know why they form.  This was, indeed, a botanical mystery until a much older Miller saw the discovery of genes that cause leaves to modify into flowers.

If we teach our children a God-of-the-Gaps--that God must exist because science cannot explain certain natural phenomena--then we are setting them up to lose that belief as science progresses, especially if they become scientists.  Teach them that we must have a regular, predictable world in order to recognize miracles; that we live in a natural as well as a supernatural world; and that God is the answer to the question, "Why is there something instead of nothing?"

Cloud Study Week 2

The second week's activity was for the students to research and create a cloud classification system.  It was meant to be done as a Problem Based Learning exercise, but our kids did not do well with this approach at all.  The difficulty was that none of them were adept at extracting information from their book sources, so that only led to confusion when trying to pull things together as a group.  Ultimately I gave them each books to take home so that next week they could all bring back information they learn.

I have been looking for online resources for the kids to look at, too.  One of the best sites I have found is Windows to the Universe, which has a wealth of information for all fields of science. Their teacher resource section for Atmosphere and Weather has several activities relating to clouds.  It also has this nifty cloud viewer to print and use for classification.  We have decided to continue our co-op until the end of June so I can find some extension activities here if we finish the NASA packet.  The student page about clouds has a lot of great information for the kids to read.

Another site I got from Library of Books, Links and More: Crazy About Clouds was NOAA's JetStream--Online School for Weather section about clouds.  They have two interactive cloud charts (main page and classification page,) a pdf cloud observation log, and a cloud identification wheel to cut out and use.

Finally, I found a neat article about Luke Howard, the man who named the clouds.  It's from The Weather Notebook, a great resource from the Mt. Washington Observatory that is still available though stopped posting new material in 2005.

A site a just recently came across is NASA Virtual Skies.  This has all things aviation, from math, to physics, to weather, to technology.  It includes teacher resources as well.  I found great information on clouds including a chart of cloud map symbols.


Hopefully the kids will do a little better with the group dynamics once they all have some information under their belts.  I am going to read more about PBL from a teaching perspective to find some tips to encourage my students.

We Found Them All!


I just thought I'd mention that we found all 10 of the Mystery Classes! The kids were very excited to see the posting on the web site and to see the locations displayed on the animated globe.
