Lab 1: Tao of the Molecular World Compare tetrahedrons; view caraway & spearmint (use Lab01_Tao in Structures menu) Surfaces jmol view (will be presented in lab)[Created by Frieda Reichsman) Dan Damelin's
electronegativity gizmo (courtesy Dan Damelin & the Concord Consortium) Dan Damelin's demo of bond strengths You're so far away--where's an electron? Brian Cox on electrons, waves & orbitals--not directly relevant, but fun & interesting The (molecular) world according to Bruce unfinished, but perhaps useful Periodic table with access to great electronegativity displays Chemistry: a volatile history (BBC show online about discovery of the elements) Interactive periodic table Other representations of the periodic table Yet more periodic tables 20 things about the periodic table MIT on wettability and surface tension Nice explanation of electronegativity from chemGuide Scaling: Size, spacing of proton & electron (scroll right to find the electron!) S.F. Exploratorium experiments involving ice & angles APPLICATIONS Making bread (with some molecule-y insights) H-bonds and spider silk strength Kevlar: H-bonding saves lives non-stick chewing gum! (try 'why things stick' & 'shoe testing') Better paper (think cast iron!) through H-bonding An African desert beetle that uses principles of this lab to harvest water Periodic Table of Videos--each element linked to a video about the element HHMI structural images (stick and 3D) of common molecules (aspirin, sugar...) Secrets to rose petal's beading of water Wonderful Question/Answer page on orbitals, energies, electrons, light Hydrophobicity to clean up oil spills Wherefore capsaicin (the hot in hot peppers)[structure available in Structviewer under 'Other'] Overview of how we detect/classify scents FURTHER READING Nice write-up on electronegativity Rings & Double Bonds: 'Aromaticity' |
