Wild About Tie Dye
Filed under Teaching Moments
Lots of kids learn how to do tie dye, but the fifth graders at Wilder Elementary got a dose of art and science today when yours truly and art teacher extraordinare, Jill Day, approached the activity from a slightly different angle. You won't find the science of tie dye in the fifth grade curriculum, but today's lesson was both a gift from the Wilder staff and PTO and a rite of passage as these students move onto middle school. From the science perspective, the students learned about three "secrets" of tie dye, and on the art side, Mrs. Day covered the coolest way to use colors in a tie dye pattern.
In addition to washing their tie dye t-shirts tonight, the students were invited to share some of the "secrets" they learned and some of the finer points of learning the "real" tie dye methods (as one of the students said, "Direct from the tie dye hippie artists to our classroom!") The students will be posting their comments all night long... check back tomorrow and we'll even have some pictures and video up … (more...)
I love Halloween. One of my favorite activities is to "carve" pumpkins using a simple reation inside the fruit. First, you carve the face then carefully replace pieces. After creating a reaction by generating a gas inside and igniting it (ask your local chemistry teacher for the details) the face pieces are blown off with a small explosion.
Halloween is more than 100 days away and I just couldn't wait. So I initiated the new weather anchor at the local Denver television station by introducing her to carving watermelons. The problem was, we didn't really carve the watermelon, it exploded. 
Our week-long salute to amazing science teachers wraps up with a visit to Heritage High School in Littleton, Colorado, where chemistry teacher Wally Keesecker gets students fired up about science. Wally is well-known for his attention-grabbing science demos that introduce students to real-world connections to everyday chemistry.
The next stop on our week-long tour was Hamilton Middle School in the Denver Public Schools to shine the spotlight on Ms. Emily Pringle, science teacher extraordinaire. Emily Pringle has taught there for eight years and uses the scientific method to make the light bulbs come on in her bright, young eager students. She and the kids showed us her candle lab experiment, also known as the "composition of air" demonstration. Here's the concept... A candle sits in the bottom of a dish full of colored water. The candle is lighted and covered with a test tube or jar. When the candle burns out (because of the lack of oxygen), the water rises in the test tube. Data is gathered as to the volume of water that displaces the air in the tube. Ms. Pringle's class concluded from the experiment that 21% of the air that we breathe is oxygen (and the students are correct!). 
When it comes to doing science, I'll volunteer for anything - fear is not a factor for me. Then I visited Pam Schmidt's class at Thunder Ridge Middle School in Centennial, Colorado... and 49 of her pet snakes! That's right, at 5:30 in the morning, I was greeted by a room full of enthusiastic kids all holding snakes - big snakes. Each snake has a name - there's Phantom, a 12' 11" Albino Burmese Python and Jazira, a 16" Blotched King snake. Pam loves snakes, and shares that passion with all her students who learn plenty about their biology, habitat and eating habits.
