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.

This is an especially fun visit for Steve since Wally Keesecker was his 8th grade science teacher in the Littleton Public Schools. “People like me make the decision to go into education after being inspired by an amazing teacher. While I didn’t exactly know that I would one day become a science teacher, I knew that I wanted to do something in education after experiencing someone as amazing as Wally Keesecker,” says Steve Spangler who is like a kid in a candy store whenever he pays a visit to his former science teacher.
Wally and his teaching colleagues dazzled us with two demonstrations centered around a Halloween theme. The first demo illustrated a chemical reaction that oozed from the eyes and mouth of a carved pumpkin. Because of safety reasons, Mr. Keesecker did not share his secret recipe for the reaction he featured on television, but we learned that a similar effect can be achieved by placing a glass of hot water in the carved out pumpkin, add a squirt of Dawn dish soap to the water and drop in a chunk of dry ice. Bubbles filled with carbon dioxide gas will ooze from front of the pumpkin – very cool! Here are more Halloween Science demos you can try with dry ice.
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!). Read more.

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. Read more.

When you work on the morning show of a news station, getting up early is just a way of life. The alarm clock went off at 3 AM this morning and I was on my way to meet another great teacher. The kids at Our Lady of Fatima Catholic School in Lakewood love Fred Scherrer. He makes science come alive for 4th, 5th and 6th graders. Most days you’ll find him in his white lab coat, hunched over some kind of hands-on experiment that gets his kids all amped up and ready to learn. Read more

I approached my television producer with this idea several months ago… let’s invite viewers to nominate their favorite science teacher to receive a special visit from our morning crew at their school during our “Mad About Science” week at 9NEWS. My producer didn’t even have to think twice about the idea – do it! Within the first few hours after we made the announcement on-air, emails were coming in from all parts of Colorado. Every teacher nominated was worthy of a visit, but travel to some of the far reaching areas of Colorado played a factor in the selection process. The producers selected 5 amazing teachers who have their own special way of getting students excited about science.

We hit the road and made our first stop at the University of Northern Colorado to visit Professor Courtney Willis who prepare students for a career as classroom teachers. But these are no ordinary teachers of science… these pre-service teachers are getting hands-on experience in learning how to create science lessons with impact. Read more.
The explanation is simple if you understand physics and the principles of force, mass and weight. The weight of the person on the bed of nails is distributed across a greater surface area. One nail would be bad. Three thousand of them work fine.
