NSTA National Conference | BSCS The National Science Teacher Association’s (NSTA) mission is to promote excellence and innovation in science teaching and learning for all. Many BSCS science educators are members of NSTA and have presented at the NSTA National Conference for many years. On this page you’ll find session presentations given by BSCS science educators at NSTA conferences, all in downloadable PDF form. Click on session titles to download presentations. Please note: PDFs of BSCS session presentations and handouts will be posted within one week of sessions.

Mobile Computing in App Inventor | Mobile CSP IPCC - Intergovernmental Panel on Climate Change BJC - Beauty and Joy of Computing Howtoons ITSI run Electrons are constantly on the move, so rather than pinpointing where an electron is, it's more useful to depict regions of electron density - regions where an electron or an electron is most likely to be found. WHAT TO DO: Model 1 An atoms's electrons repel each other, but they're fiercely attracted to particles that are positively charged. Use the buttons below the model to view attractive and repulsive forces that four regions of electron density experience. The second model contains an atom that has 2, 3 and 4 regions of electron density around it. WHAT TO DO: Model 2 Use the controls beneath the model of an atom with two electrons to explore how 2, 3, and 4 electron dense regions position themselves around an atom.
