Science

DIY science is the perfect way to use your creative skills and learn something new. With the right supplies, some determination, and a curious mind, you can create amazing experiments that open up a whole world of possibilities. At home-made laboratories or tech workshops, makers from all backgrounds can explore new ideas by finding ways to study their environment in novel ways – allowing them to make breathtaking discoveries!

Color thermal inkless printing technology

Color thermal inkless printing technology

My father recently drew my attention to an article in IEEE Spectrum about the so-called “Zink” printing technology commercialized by a group of former Polaroid employees. Zink, an acronym for “zero ink,” uses special paper with three layers of embedded dye crystals activated by heaters in the print head. Solely by controlling the temperature and duration of heat pulses delivered by the print head, the yellow, magenta, and/or cyan layers may be selectively activated. It is essentially a refinement of the black-only thermal printing technology commonly used, for example, in cash registers and label makers. By eliminating the requirement for ink or toner, Zink promises to produce dramatically smaller and more portable color printers, and has already been incorporated in several “digital polaroid” style cameras with integral photo-printers, such as the Polaroid PoGo Instant Digital Camera.

History of curved origami

History of curved origami

Interesting article from MacArthur fellow Erik Demaine covering the history of origami-style models that include curved folds. Shown above is “Concentric Circular Tower” by late UCSC Professor and noted computer scientist David A. Huffman (Wikipedia), whose curved-origami work was covered posthumously by the New York Times in 2004. The Flickr curved fold pool is chock-a-block with fascinating models of this type.

STEM resources for teachers

STEM resources for teachers

This weekend I had an opportunity to attend a renewable energy workshop organized by the Southeastern Massachusetts Achievement and Retention in Technology group at Bristol Community College. The morning was packed with teachers sharing their lesson and unit ideas on ideas based around the STEM subjects of green technologies and energy.

The college offers a Lending Lab for tools and lab equipment that most schools are unlikely to stock. Through using these equipment resources, teachers can get their students’ hands onto enough materials to for a series of lessons on windmill design, hydrogen cars, air purity testing, and more. Teachers shared their experiences in bringing this equipment into their classes and how it affected student learning.
