Plant and Animal Tissues
No full textIn this lab activity from the Biotechnology Alliance for Suncoast Biology Educators, students will use a compound microscope to examine a few simple plant and animal tissues and explore the idea of different cell types that specialize in their form and function. Students then submit a set of drawings to demonstrate their learning. The lesson includes background information on different types of tissues, the materials needed, and the procedure
Estimating Rates of Photosynthesis
No full textIn this lab activity from the Biotechnology Alliance for Suncoast Biology Educators, students will explore photosynthesis, develop a testable hypothesis about the effect of light quality (color) on the rate of photosynthesis of Elodea, and graph measurement data from their testing. The lesson includes background information on photosynthesis, the materials needed, and the procedure
Chromatography
No full textThis lab activity from the Biotechnology Alliance for Suncoast Biology Educators covers background information on the basic types of chromatography and has the student separate pigments extracted from pens and plant leaves using paper chromatography. The lesson includes the materials needed and the demonstration procedures
Understanding Science
No full textThe mission of the Understanding Science website is "to provide a fun, accessible, and free resource that accurately communicates what science is and how it really works." The project has a specific focus on assisting teachers in keeping young people interested in science; to support this goal, the site includes a range of materials for teachers. Visitors can start with the Site Tour area to learn about the structure and organization of the site. Moving along, the Understanding Science 101 area includes quick reviews of topics like How Science Works, What is Science?, and Why Science Matters. The Resource Library contains classroom activities, teaching tools, and strategies for keeping students thinking and engaged. Visitors can also use the Correcting Misconceptions area to address certain commonly held beliefs like Science is complete or Science is a collection of facts. Finally, visitors can sign up to receive updates when the site adds new information
Distillations Podcast
No full textCreated by the folks at the Chemical Heritage Foundation, Distillations is an award-winning podcast that offers commentary and perspective on the past, present, and future of chemistry. The program is hosted by Meir Rinde and new episodes are issued every other Friday. The archive here contains over 150 podcasts with titles such as "Shipwrecks," "Sweat," and "Something in the Air." Visitors can also sort through the documents by category and learn about the Distillations staff. The archives date back to 2007, so there's plenty to explore and visitors are free to use the materials as they see fit. An episode or two might be the perfect way to keep a group of students intrigued by the world of chemistry
What is ATE?
No full textThe ATETV project delivers web-based videos to connect students to careers in advanced technology. This episode of ATETV explains what advanced technological education is. The importance of math, science and applied knowledge is demonstrated. Students training in a variety of programs like industrial maintenance, remotely operated vehicles and welding are shown. Running time for the episode is 4:55
A Simple Fiber-Optic Communications System
No full textIn this video adapted from the ICT Center, students will "learn how rise-time analysis is performed to determine the maximum data range of a fiber optic communications system." The video also demonstrates how a transmitter, fiber, and receiver work together. The material is intended for students in grades 11-12. Running time for the video is 5:31.The lesson is accompanied by discussion questions, teaching tips and state educational standards. Users who sign up for a free account can save the resource and download the video as well
Bowden's Hobby Circuits
No full textThis website is a small collection of electronic circuits for the hobbyist or student. The site includes over 100 circuit diagrams, links to related sites, commercial kits and projects, newsgroups and educational areas. Most of the circuits can be built using common components available from Radio Shack, Digikey, Jameco, Mouser, Allied electronics, or salvaged from scrap electronic equipment. Most of the circuits have been built, tested, and believed to perform as described
Industrial Maintenance Class Produces Multi-Skilled Technicians
No full textThe ATETV project delivers web-based videos to connect students to careers in advanced technology. This episode of ATETV allows viewers to visit an industrial maintenance class where students master skills from welding and HVAC to robotics and electronics. The class uses a systems approach which can be applied to different settings. Running time for the episode is 3:54
DNA Microarray
No full textThis animated YouTube video, created by Southwest Center for Microsystems Education (SCME), illustrates how DNA microarrays work in the context of nanofabrication. The animation and associated narration describe "how a DNA microarray identifies complementary DNA (cDNA) strands from a sample. On the substrate of the array are synthetic ssDNA stands or oligonucleotides (oligos). Each grid in the microarray contains hundreds to thousands of oligos with a unique DNA sequence. These oligos hybridize with cDNA from one of two samples. There are thousands of grids on the array allowing for the simultaneous identification of thousands of different DNA sequences. Each sample cDNA is "tagged" with the red or green tag as shown in the animation. The "tags" enable an interpretation of the DNA hybridizations." A supporting learning module and activities can be downloaded from the SCME website
