If your school has a website maintained by someone you know, you might enjoy adding some free content using FreeDictionary.com. Other educational widgets are also available with a bit of "Googling."
This link has examples of what the blocks can do on the left-hand side and the HTML code in the boxes on the right. You can easily use these, for example, to look up all the words which end in "-able" and all the words ending in "-ible" to make a comparison. There are vocabulary activities and this-day-in-history resources as well.
