Molecules Made: Glucose, Amylose (linear glucose chain in starch), Fructose, Sucrose and Stearic Acid Topics Covered: Amino acids as building blocks of protein, protein structures (ribbon and backbone) and bringing in protein structures using the database in Chem Doodle Molecules Made: Amino acid template, Methionine (needed for break down of fat to release energy), Lysine (calcium absorption) Topics Covered: Aldehyde and Acid functional groups in organic chemistry Molecules Made: Formaldehyde, Citric Acid, Aspirin Topics covered: Electron orbitals, make orbitals using Chem Doodle widget, learn about VSEPR (Valence Shell Electron Pair Repulsion Theory) used to predict molecule shapes Molecules Made: Carbon dioxide, Methane, Carbonate ion, Chlorine Trifluoride, Sulfur Hexafluoride Session 2: Atom Orbitals and Molecule Shapes Topics covered: The structure of atoms - protons, neutrons and electrons, types of Covalent Bonds, learn about chains of carbon atoms called alkanes, alkynes and alkenes Molecules Made: Water, Alkanes (methane, ethane), Ethanethiol, Alkenes and Alkynes Setting up Chem Doodle 3 for our sessions Session 1: Introduction to ChemDoodle Interface

When you have drawn the target acetic acid molecule, click the 'submit' button to check your answer.Learning Goals for each class session are listed below:

The shape of the molecule doesn't matter, but be sure that you have included the double bond to oxygen and the four lone pairs before submitting your drawing. If the symbol that you want doesn't appear, press repeatedly to cycle through the possible symbols.

To overwrite an atom with the keyboard, hover the cursor over the atom and when the brown circle appears press the key for the first letter of the element symbol. You have already overwritten atoms with the label tool in the CO2 molecule. Or you can use the bond tool to quickly complete a carbon skeleton, like the one on the right above, by just clicking on existing Catoms, then use either the Set Label tool or the keyboard to overwrite the necessary atoms. o H H-c-d H 0-11 You can draw the two C atoms with the bond tool, and then use the Set Label tool to add the rest of the atoms by clicking and dragging.
