This project requires students to create a website investigating a specific element from the periodic table. The tic-tac-toe choices are designed so that no 3 in a row option is too challenging or too easy. For differentiation you have several options- you can allow students to pick any three from the board or have students complete only 2 or 1 square. You can also require students who need enrichment to complete 4 or even 5 squares. Squares incorporate a variety of Web 2.0 tools and 21st century skills. Project options also include a variety of learning styles and skills.
