Now that you have finished taking notes on your Ancient Greek landmark, you should be writing your stories in writing class. Today in computer class you will be looking for a photo of your Ancient Greek landmark and taking a green screen photo(s). Next week you'll superimpose yourself into your photo. Here are some sites you can use to find a photo. I like these two sites because it is easy to find a "public domain" or "creative commons" photo. Remember to download the "full size" image and put it in your personal folder. Don't forget to give credit for using the photo. You can save the information in a Microsoft Word document.
