    I am glad this is still available- I love your style of teaching and it helped me get through my first few years of teaching at a low SES school with no science resources~ Thank you

      Lisa – that is so great to hear, we should all help each other since we all have the same goal, but we don’t all have the same resources or experiences. I am still learning from other teachers, too. Liz

    Hi! I love the worksheet you created on finding the valance electrons. I tried to download the powerpoint slides that go along with the work sheet but it says something about the file being password protected. Is there another way that you can send it to me? I would love to use it in my 7th grade science classroom. Thanks!!

      Hi Nikki, The power points are in a ‘read only’ format and can be used by anyone, they just can’t be saved and edited. A lot of the ppts I make are posted in places I don’t want them to be, for example on Teachers Pay Teachers or on other websites, so that is why they are in Read Only and can be used by accessing the link. Thank you for understanding. Liz
