    How much info is too much info per lesson?

    I find it difficult to teach bonding on the IGCSE course (Cambridge). I always want to start adding in other info that is not on the syllabus. I have now prepared a lesson for sale, but it feels very info heavy. I have included the following topics:

    - introduction to bonding
    - a reminder of what ionic bonding was all about (from previous lesson)
    - the definition of covalent bonding
    - some slides explaining stability and valency ( part reminder but some new terminology)
    - dot and cross for H bonding
    - dot and cross for Cl bonding
    - dot and cross of O bonding
    small explainer on different ways to represent and single , double and triple bonds. At this point I feel like it is a lot to take in - but there is one part left in the course to explain which is bonding in Methane and HCL. So I include links on the lesson so student change perspective and see a video on how to generate the dot and cross diagram for these molecules as well as including how to do this (with answers) - a sort of check on understanding

    But I have left out the concept of structural formula and why we draw the bonds at angels as well as leaving out properties of covalent bonding ( as not on syllabus). However it would really complete the lesson. So my question is - too much info or add it anyway?

    After seeing this, I lost all interest in helping...

    Okay! I see your point. But it was/is a genuine concern. I am never sure how much to add to a TES lesson so I guess the question is best suited for the authors group.....I will move it there.

    You clearly don't see my point when you post the identical OP in a different forum. The issue isn't who you are asking, it is why. If you were asking purely because
    and you didn't want your students to struggle due to your deficiency, I have no doubt posters would be willing to help. To seek advice on how to make more money despite your deficiency riles me.

    well - its one and the same thing. What I put in my lessons on TES is what I teach, sorry my comment riled you so much but thanks for interacting. I guess seeing my question didn't generate any answers perhaps more people feel the same way . For me it was purely a technical question but I am confident I will figure it out.
