Description
- Overview:
- This video resource is presented as a real-world application of chemistry in the field of conservation archaeology. Conservator, Francis Lukezic, walks through the conservation practices for waterlogged archaeological wood and explains the chemical and cellular processes at work. Use to support Maryland/NGSS for Grades 5, MS, and HS. For 5-PS1-1 and MS-PS1-1, have students watch or perform the paper clip demonstration and discuss how the hydrogen bonding of water allows this then is disrupted by the soap; have students develop diagrams explaining the phenomenon of surface tension on the molecular level. For HS-PS2-6, have students watch or perform the sponge demonstration and discuss how the molecular structure of the wood makes it vulnerable to becoming waterlogged then brainstorm materials that are more resilient to water and discuss the uses of the materials. For interdisciplinary connections to geography and history, have students research why Maryland archaeologists do or do not discover the materials brainstormed instead of wood. If you evaluate or use this resource, please respond to this short (4 question) survey bit.ly/3DhRumA
