Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
High school students will explore the structure and property changes of water through videos and classroom discussion. They will be introduced to atomic arrangement of solids by looking closely at carbon in different forms, such as graphite and diamond. They will view and manipulate online files of graphite and diamond structures to discover similarities and differences. An extension activity is research of buckyballs.

1. Students should view Structure and Property Changes of Water QuickTime Video video (1 minute 5 seconds)
2. Teacher and students should discuss how phase changes of water affect its physical and chemical properties (3 minutes).
3. Students should research and list the meanings of the following terms: condensation, deposition, evaporation, freeze, gas, liquid, melt, solid, and sublimation.
4. Students should complete Part I
Structure-Property Relationships Vocabulary PDF Document(2-5 minutes).
5. Teacher and students should review worksheet answers and talk about underlying concepts (5 minutes).
6. Teacher and students should review how adding or removing energy affects water using the terms defined above (10 minutes).
7. Students should complete Part II
Structure-Property Relationships Diagram PDF Document(20 minutes).
8. Students should view Atomic Arrangements in Solids QuickTime Video video (1 minute 30 seconds).
9. To view and manipulate the atomic structures of graphite and diamond, students should visit an alphabetical list of common molecules hosted by Reciprocal Net by copying and pasting the following url into their browser (3 minutes).
Students should then scroll down the list to find, open, and manipulate the graphite and diamond files, noticing how their structures are the same or different.
Reciprocal Net is funded by the U.S. National Science Foundation as part of the National Science Digital Library project and is open for use to the general public including students, teachers, and researchers.
10. Teacher should lead a discussion asking the students questions about similarities and differences between diamond and graphite (3 minutes).
11. Teacher should lead a discussion about other objects whose physical properties change as simple molecular-structure changes occur (ex: iron horseshoes vs. iron swords, tearing 1 sheet of paper vs. tearing a ream of paper, etc).
12. Students can research a "buckyball." What is it? How is it similar/different from diamond and graphite
