This project aims to demonstrate the effective use of technology to a student-centered, model-based approach to secondary science teaching. Using a variety of computer-based manipulable models and probeware, MAC teaches students how to create, refine, and apply mental models to improve their...

The Molecular Expressions website features photo galleries that explore the fascinating world of optical microscopy. The site offers a large collection of color photographs taken through an optical microscope (commonly referred to as "photo-micro-graphs"). The Photo Gallery contains an introductory...

The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical phenomena." This particular one deals with molecular polarity. When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. This...

This website from Duke University is a project-based data archive that collects thousands of 3D morphological data and models. The website allows researchers to store and organize, share, and distribute their own 3D data. Registered users can search for and download 3D morphological data sets that...

This classroom module will help students understand "how a polymer based multilayered coating method can be used to control the release of biological agents for different applications." The experiment is described step by step in the document; photographs are also included. The activity is intended...

In this webinar, published by the National Center for Nanotechnology Applications and Career Knowledge, Mrunalini Pattarkine from Harrisburg University discusses efforts to develop a trained workforce in nanobiotechnology. Pattarkine provides an overview of nanobiotechnology, career opportunities...

The National Center for Biotechnology Information presents the first full release of all NCBI Reference Sequence (RefSeq) records. RefSeq "aims to provide a comprehensive, integrated, non-redundant set of sequences, including genomic DNA, transcript (RNA), and protein products for major research...

This page from the National Center for Biotechnology Information (NCBI) offers a set of tutorials, online tools, FAQs, and documentation to help users make full use of NCBI's bioinformatics tools. The tutorials, which target both new and veteran users, cover NCBI's BLAST and PSI-BLAST, the Entrez...

This video, provided by Digital World Biology, is from the 2022 Antibody Engineering Hackathon, an event where teams collaborated to develop Course-based Undergraduate Research projects (CURES) for students studying biotechnology. During this presentation, presenter Sandra Porter provides...

This lecture from the iBioSeminars project is presented by Nico Stuurman, professor of cellular and molecular pharmacology at UC-San Francisco. Fluorescence is a physical phenomenon in which a compound absorbs light and re-emits this as light of a usually higher wavelength. Since the excitation...
