The Biology Project Sources of Food Affect Dietary Adequacy of Inuit Women of Childbearing Age in Arctic Canada The Science Spot Reference Cards I have created reference cards for many of the units/activities listed below, which are designed to replace the student worksheets and some lab pages for those units. The cards are printed on card stock (back-to-back) and laminated for student use. Students use overhead markers to add notes to the pages as we discuss each lesson and keep them to review for the unit quizzes. (You could also have students record their answers in a lab notebook rather than write on the pages.) At the end of the unit, they clean them off with a wet cloth and turn them in so they are ready for the next class! Daily CSI Challenges I start each class period with a warm-up activity targeting forensic science concepts and other skills (observation, problem-solving, etc.) Forensic Science A to Z Challenge (PDF) - Students must use clues to identify forensic science terms and then find them in a "bent word" style word search.

How does caffeine affect the body? Biologist Neal J. Smatresk--Dean of the College of Science at the University of Texas at Arlington--offers this explanation: Caffeine--the drug that gives coffee and cola its kick--has a number of physiological effects. At the cellular level, caffeine blocks the action of a chemical called phosphodiesterase (PDE). Historically, cAMP was the first second messenger ever described. Thus, when caffeine stops the breakdown of cAMP, its effects are prolonged, and the response throughout the body is effectively amplified. Caffeine would be expected to have this effect on any animals that used these neurotransmitters to regulate their heartbeat.

The science of attraction - Dawn Maslar When two people join a dating website, they are matched according to shared interests and how they answer a number of personal questions. But how do sites calculate the likelihood of a successful relationship? Christian Rudder, one of the founders of popular dating site OKCupid, details the algorithm behind 'hitting it off.'
