InThinking is a great organisation. I got my first category training with them and it was one extremely useful to my teaching. In addition, the website is highly in line with the training and the IB curriculum and also very helpful. It is such a blessing...

This is my first year of full-time teaching, and I would not have survived so far without the vast pool of resources available on the InThinking Chemistry site. From teacher prep notes to lab suggestions to last-minute homework assignments to understandings...

The InThinking Chemistry website by Geoffrey Neuss is a valuable resource. The presentations are useful and supplement my course textbook by giving students tasks throughout to check their understanding. The topic introductions provide points of interest...

    Thanks Geoff. I gave that very point of view to my colleague today. I am still a Chemistry teaching novice though and your work goes a long way in helping my students succeed. Both of you resources are great- here on InThinking and then with...

    Hi Dan, Thanks for this. I very much agree with two of the points you make. There is now much more material that is specifically targeted to the current four options for students to be able to teach themselves (thanks for the link to your videos!)....

    Hi Geoff, I don't dispute your observation about the1 teacher taught option. I got that advice from the Bio OCC moderator 4 years ago and many veteran Group 4 teachers. However, I have to say that it probably depends on the school. The teacher...

    Electrons in atoms
    Hello Sigrid, In the old programme some definitions were actually listed in the syllabus (under Objective 1) and were asked as such in exams. The new programme does not actually list or ask for definitions, even so, I think students should...

    Electrons in atoms
    Hi Geoffrey, just one small item that caught my attention: in former exams Students were punished for not using the 'molar' definition of the ionisation enthalpy. Has this been changed now?
  • Hello Chris, CH3NH2 is known as methylamine, methanamine or aminomethane. As I understand it. it seems generally the case that for when C is 1, 2 or 3 the names methylamine, ethylamine and propylamine are still the preferred IUPAC names whereas...

    Organic fundamentals questions (1)
    Hello Geoff Q2(d). Isn't methanamine the name the IB now uses? Do you think they will still use the old names in exams (aminomethane is another version).

    2. Atomic structure
    Hello David, The higher the charge but the lighter the mass the more it will be deflected, so the answer is C.

    2. Atomic structure
    Hi Geoff, Re:Q 14- Should the answer be D as it has the highest mass and charge?
  • Hi Cindy, Because it is a temperature rise, not the actual temperature, and a temperature rise of 14 K is the same as a temperature rise of 14 oC.
  • Hi. Why is B the answer for #6 when the specific heat capacity units are in K but the answer uses 14 C instead of 287K? thanks
