This lesson, presented by the National Nanotechnology Infrastructure Network, introduces elementary students to the concept of using tools to gather information about the world around them. This provides a useful skill foundation for students as they continue into middle and high school and encounter more complex tools. Especially for nanotechnology, the use of tools is extremely important because our knowledge of nanoscale objects relies entirely on the data collected from those tools. Included in this lesson are: Student Worksheet #1, Student Worksheet #2, Student Worksheet #3, Optional Tool Matching set k-2, Optional Tool Matching set 3-5, Center Directions - Matching, Center Directions - Seeing, Word Match Sheet, and Tool Cards.
