Recent U.S. initiatives to mandate the labeling of foods made with genetically modified organisms (GMOs), including the heavily contested Proposition 37 in California, have failed. But these initiatives have jump-started public conversations about the use of biotechnology to improve crops and foods. Making crops more pest-resistant and boosting the nutritional value of staple foods are two examples of genetic modification.
Teachers and parents can help students better understand current GMO discussions by exploring the science and technology behind GMOs and talking about ways in which GMOs are integrated into our food chains. For more information about GMOs and suggestions for hands-on student and classroom investigations, see "Altered Foods: Labeling, GMOs, and Biotechnology" on the Science Buddies Blog.

Trick or Treat Science
New Biotechnology Techniques Exploration
Halloween costumes may be tucked away for the year, but the candy may linger for months to come! The newly released "What Makes Candies So Colorful? Investigate How Gel Electrophoresis Unlocks the Color Code!" Project Idea guides students in an investigation of candy coatings. With only certain color additives available, how do candy makers achieve their range of colors? Using the STEM Electrophoresis Kit from Bio-Rad Laboratories, students can investigate the dye molecules that make up popular candy colors. Do all candy makers use the same color formulas?
More 'Spooky' Science
You and your students can build on last month's tricks and treats with a variety of hands-on science projects. From other candy-based investigations to glow sticks and eerie music, there are plenty of fun science angles to explore. For Halloween-inspired science connections, see the "Science Projects for Trick or Treat" and "More Halloween Science" blog posts.

Born on November 7, 1867: Marie Curie, two-time Nobel Prize-winning chemist and physicist whose research on radioactivity included the discovery of both polonium and radium. In the "Build Your Own Radon Detector" electronics Project Idea, students build and use a simple radiation collector and an ionization chamber to measure radioactivity. (A Project Kit is available!)
