What student wouldn’t want something scientific named after him or her?! This experiment from Teach Engineering is a hands-on activity that allows students to make their own temperature scale before using that scale to measure temperatures in different places. It also shows how to convert Fahrenheit to Celsius, an appropriate activity because the Fahrenheit thermometer was invented in December, 1714. The instructions of what the students are to do are very clear and detailed. The plan includes motivation for the lesson, necessary vocabulary, materials needed for the experiment, and assessment criteria.http://www.teachengineering.org/view_activity.php?url=http://www.teachengineering.com/collection/cub_/activities/cub_energy2/cub_energy2_lesson06_activity1.xml
Watch this beautiful slideshow of photographs by Kenneth Libbrecht from his book, The Art of the Snowflake. The twelve slides are stunning in their color, delicacy, and, of course, symmetry. Each slide has a brief explanation of the snowflake which explains properties of crystals and why snowflakes can look so different from each other. Find out about stellar dendrites, sectored plates, and how local environment affects the snow crystal as it falls through the sky. What a great reminder of the incredible beauty to be found in the natural world.
