Cris DeWolf

Hello! I teach Biology, AP Biology, Earth & Space Science, Astronomy, and Oceanography. 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.

You could show how density changes when water is heated or cooled by using colored water. Heat some water with red food coloring and slowly put it into a clear container that has half full with room temperature water. It should form a layer that "floats" on top of the cooler water. Then do a similar thing with a new container half filled with room temperature water and slowly add ice water with re...

I just heard about the DIG Texas Blueprints on the NESTA Facebook page. Have any of you used them? What do you think? Here is a link to the site:

I help operate a network of educational seismographs in Michigan (MIQuakes) that is part of the Incorporated Research Institutions for Seismology (IRIS) "Seismographs in the Schools" project. Even without your own site-based seismograph, you can display near real time records of seismic activity from a variety of online sources using free software called jAmaSeis. This software can be downloaded f...

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.
