"Ever wonder why we are made up of the particular ratio of elements that we happen to be made up of? The answer may be very simple. Perhaps we are that way because the universe is that way." This infographic reminded me of this H21 lesson (http://blogs.henrico.k12.va.us/21/?s=element+survivor&x=-1067&y=-38) and could provide a neat extension/summary for the lesson. After the students create their products and justify their choices, the teacher could show the infographic on this page and have the students compare and contrast their choices to the infographic and discuss "Why do you believe the human body contains these proportions of the listed elements?" Then, after an appropriate amount of time for the discussion, go for the big reveal and show the graphic that displays the abundance of each element in the universe.

"Tables charting the chemical elements have been around since the 19th century - but this modern version has a short video about each one. We've done all 118 - but our job's not finished. Now we're updating all the videos with new stories, better samples and bigger experiments. Plus we're making films about other areas of chemistry, latest news and occasional adventures away from the lab." Interesting video resources for each element on the periodic table. This type of thing might be cool for students to produce/create. They could design an experiment around an element, videotape it, and put up the videos as a class/school.

"goREACT is a free iPad and Android app from the Museum of Science and Industry, Chicago. This free iPad app allows students to virtually create chemical reactions. To create the reactions students simply drag elements from the periodic table to the "reaction area." The app features suggested reactions to help students get started. In all there are nearly 300 chemical reactions supported on the app. The app includes pictures and videos related to the reactions that students can virtually create on goREACT."

This the version that will accept any HTML element and render it as the variable.

By viewing the page source here, you can now make multiple variable webpage generators. They might be useful for things like this which is a for refining project based questions or you could use as elements in a writing prompt. I have another one that randomizes images as well that works slightly differently.

This seems like a decent interactive for an introduction to atoms/elements/period table. Have the students click through several atoms in order and then discuss: - What do you notice? - What do you wonder? - Predict what the next atom (or the atom 17 clicks away) will look like. Explain your response.
