product central Science and technology sets The new LEGO Powered Science & Technology Set, designed for 4th grade and up, gives students the option to build 16 different models focusing on physical science and technology concepts including powered forces and motion, simple machines, measurement, moving energy, magnetism, and more. The addition of power expands the learning potential and boosts exploration. Great for teaching teamwork as two building guides for every model are included— one for Student A and one for Student B. Each student assembles a portion of the model and then the two team up to complete the building process. For additional information, visit www.legoeducation.com. New tools, equipment, and teaching aids to make you a more effective educator. The better way to remove paint The Eastwood Company’s new line of Soda Blasters and Soda Blast Conversion kits for popular abrasive blasters are environmentally friendly. Blasting with baking soda has long been preferred by professional shops because it removes paint without damaging the base metal, glass, or trim, so little disassembly and masking is needed. The efficient design allows users to soda blast with as little as 7 cfm at 80 psi with greater precision and control. Check out this new EPA and OSHA-approved environmentally friendly way to remove coatings. Call 800-345-1178 or e-mail jsloane@eastwood.com.
