Mr. Nike! My Sneaks Slide Too Easily!!!!

My cherubs, today, elevated a laminate board, placed a sneaker on the board and tilted it until gravity overcame friction. Then, they applied a layer of water between the shoe and board and found the lubricate decreased friction, permitting gravity to pull easier on the wearing apparel. Needless to say, a whole bunch of deodorizer was used in the room. Whew!

Have a great weekend, folks -- I gotta work, tomorrow.

Lee Lee's Brain Burped

Ah, Lee Lee, talk about a bad hair day. But, thanks for the entertainment. I hope we had fun with your ditsy math display in class. I know I enjoyed an otherwise boring math problem. Poor Lee Lee was trying to show that a 100-gallon bottle of water contains 21 gallons of oxygen, using the constant of 21%. A bit of algebra confused her. In fact, now that I think about it. That was the type of equation that confused you when it was a math homework assignment several weeks ago. Oh well, all better, now.

I Dig Archaeology
Hey, check out my website! I am adding more about archaeology. It's a dirty little subject few discuss.

Have a great night, folks.

Inquiry-based Learnin' Goin' On

Okay, so, you determined that a 59-mL test tube holds about 14-mL of oxygen. Great. Although you did not get 21% oxygen in the atmosphere, you were close. So, today, I asked, "How come, y'all did not get 21%?" Well, answers varied and it was great. Also, I asked, what if we used a 200-mL test tube, or a larger candle? Of course, the volume of oxygen would change, but, prove that it would still be proportional to the total volume of the test tube. Made for some great intra-group discussions.

The Bionic Website
The district has revamped the appearance of our websites. In turn, I am rebuilding my website. Streamlining and organizing all units. It's gonna be so cool, when I'm done.

Archaeology Society Meetin' Tonight
The local society, in conjunction with the Muncy Historical Society are gearing-up for the opening day of the Pennsylvania Canal Lock excavation at Muncy, on Thursday, April 26. The site is open to the public. If you want to learn more about local history, play in the dirt, or just understand the meaning of archaeology, I urge you to go the dig site, off Pepper Street, in Muncy. Here is the link to the Muncy Historical Society webpage. Just click-on the link. http://www.muncyhistoricalsociety.org/dig/index.html Also, the local society is looking for new members. We meet tonight, at 7 p.m., in the Thomas Taber Museum. Use the parking lot entrance. Robin Van Auken has a neat presentation planned for tonight. Hope to see you there. Getting to know our local history is a great teaching tool for our children.

Have a great night, folks.

Using Microsoft Excel to Make Bar Graphs

It was a crash course in using Microsoft Excel to convert the oxygen volume data from last week, into a digitized data table and bar graph. Nifty tool, instead of a sheet of graph paper, ruler and colored-pencils.

Have a great night, folks.
