A question that sometimes drives me hazy:
am I or are the others crazy?

  Remix — to adapt the work; any way you see fit.
    Under the following conditions:
    Do not sell these lessons or make a profit on them in any way
      without written permission
    Attribute the original source, and do not change the copyright
      footer on the pdf files.
    Do not claim these lessons as your own work.
    If you make significant changes, and don't mind, send it to me and I'll
    post it crediting you.
  Link to any page or file on this site to a webiste, blog, or wiki.
    Please do not download science-class.net files and re-upload to your
    website. I make changes to files as needed, and the most up-to-date
    version is always on this site. I have no problem with links directly to
    files on this site.
Do you sell your stuff on Teachers Pay Teachers? (Or similar sites?)
  No. Everything I make is for myself or colleagues. I don't sell, I share.
    I am not in the business of publication.
    Because I create for use, not sales, the material on science-class.net
    does not have extensive instructions, teacher notes, or answer keys.
    It is also not as "cute" as items for purchase in other places.
    I design for practical use, not marketing.
    I assume professional educators are using the resources on this
    site, and do not need or want lots of color or "fluff."
    Unless color is necessary for the activity, material created for student
    use is in black & white for ease in printing.
    Everything on this site is however, absolutely free for anyone who
    wants it.
Are the lessons and activites aligned to NGSS or state standards?
  That depends on how the lesson or activity is implemented in your
    classroom. The resources cover the content and topics in the
    Disciplinary Core Ideas of the NGSS, the TEKS, and other state
    standards. Whether or not they meet the actual intent of any
    particular standard often depends on how a teacher uses it in a
    I am hesitant to state that the resources are aligned simply because
    meeting a standard involves much more than matching content or
    topics. Making sure the content is presented in a way that allows
    students to interact with the content at the level or in the manner
    required by student performance expectations or knowledge and
    skills statements requires teacher guidance. I share materials with
    professionals, I don't write to tell teachers how to teach.
Do you have answer sheets?
  No. Since I create the lessons and activities for myself, I don't need
    them. Occasionally I include a note or two for teachers, but the
    materials on this site is pretty much just student sheets. Furthermore,
    since I use much of this material in my classes, I don't want my
    students Googling and finding the answers.
    See question above.
Do you take special requests for lessons?
  If I can. It's always a time issue and I can't promise to be able to
    provide material within a given timeline.
Do you do workshops or provide professional development for schools
  or districts?
  Sometimes. Again, it's a time issue. I do enjoy working with other
How do I advertise or get my product mentioned on your site?
  All of the advertising on this site is done through Google Adsense
    I use it because I control the number, size and placement of ads.
    I will, on occasion, advertise for other organizations.
  I am open to other advertisments, but I am extremely selective about
    what I allow on this site.
  Any product mentioned in context on a page is one I have used myself.
    Mentions of this type are not advertisements; they are testimonials.
Do you do link exchanges with other websites?
  Sure. However, the link must fit within the scope of this site.
  It must be useful to teachers of science and it must have a natural
    place on one of the pages on this site.
What did you use to build this website?
  I use Macromedia Dreamweaver as my exclusive webpage
    builder / editor.
  The site itself is hosted by IX WebHosting.
    They have the BEST technical support I have ever used.
What about the graphics on this site or your resources?
  Some I made myself. Most graphics are either purchased by me and I
    own it or comes from clker.com
    My favorite artists there are Ocal and Mohamed Ibrahim.
    I sometimes use Wikimedia commons as well.
  The icons for linking to social media came from this talented artist:
    Elegant Themes
  Some graphic resources are purchased from ©BrownCow Creatives
How can I get in touch with you?
  I used to have an email just for this site. However, the amount of
    spam I received was ridiculous. I've changed the address a couple of
    times, but having an email address on the open web is an invitation to
    junk mail. However, I can be messaged through my social media
    pages. Links are in the upper right corner of each page.
