Cris DeWolf

Hello! I teach Biology, AP Biology, Earth & Space Science, Astronomy I and II, and Oceanography I and II. I've been teaching now for 27 years. I am very active with the Michigan Earth Science Teachers Association, currently as their past president. My profile pic is from my flight on SOFIA as one of the first two Airborne Astronomy Ambassadors. This is an amazing airborne infrared telescope.

If they can make a connection to the idea that light from the sun heats the earths surface, there is something I first saw on Bill Nye's Seasons video. You use solar cells attached to a globe that are hooked up to volt meters to show how the changes by orientation of Earths axial tilt changes the amount of light.

The key to a fast, huge eruption is pressure. If you use a graduated cylinder you do not get as much pressure forcing the material out of the top as you would if you used a large conical flask. Larger reaction area at the base (more gas produced) confined at the neck/mouth of the flask, resulting in greater pressure and a more dramatic eruption. Steve Spangler has some material on a patriotic d...

5 Forensic Science Collection
We are in the process of designing a Forensic Science elective course in our department. We want to make it fun, engaging, and meaningful for our students. The activities in this collection will provide me with the tools I need to bring the department together as we explore our options. The Career of the Month and Careers in Science features will help our students see forensic science as a possible career path for themselves. There are also several useful labs included. I really like the one called Forensic Science Demonstration via Hawaii Five-O. The soil analysis they use there could also be extended to my Astronomy class when we talk about how rovers like Curiosity test for the presence of organics in the soil on Mars.

5 Heredity and Variation SciPack Review
This SciPack did an excellent job of challenging my current understanding of genetics and heredity. I teach Biology and thought that it would not require much thought. I was wrong. I would recommend this resource to anyone who would like either an in-depth refresher of modern genetics, or a deeper look at something they have a more limited background on.
