This blog (short for “web log”) is where the GLOBE Chief Scientist writes about a variety of science topics for students. Students are encouraged to participate in these discussions and respond to each other’s comments on the site to explore the topics. Dr. Peggy LeMone will update the blog every few days.

How to add a comment:

At the end of each blog article is a link to the comments/discussion for the article. To read or add comments click either the Comment(s) link or “Click here to add a comment”. It doesn’t matter which of these two links you click. They both go to all the existing comments for the article followed by space where you can add a comment if you like. To add a comment, you will need to log in first. You can click “Login” on the right side of the page to log in; or if you are on the Comments page, you can click “logged in” at the bottom of the page to log in. Type in the username and password that you got by registering. Enter your comment or question in the large box and click “Submit Comment”. Your comment will go into a list to be moderated and once it is approved it will show up with the comments for the article. It might take a day or two for your comment to show up. Watch this web site to see if your comment generates further discussion and to read new topics as they develop.
