  8. The Metric System from Big to Small

    29 Jan 2020 | | Contributor(s):: Joe Donahue, NNCI Nano

    This interactive lesson will review the metric system and relate the size and scale of objects to various metric units, including the very small nano-scale. The activity is best done in groups of 3-4 students and requires the groups to make measurements and convert them to the metric system.

  9. Size and Scale: Learning about Measurement

    28 Jan 2020 | | Contributor(s):: Nancy Healy, NNCI Nano

    Using images of objects and the SI unit of measurement, students will visualize the order of numerical properties of objects from the nanoscale to visible scale using exponents and decimals. Students will make size comparisons of objects. Students will develop an understanding of how small a...

  10. The Micro and Macro Worlds Around Us

    23 Jan 2020 | | Contributor(s):: Marilyn Garza, NNCI Nano

    This activity focuses on scale and the importance of using scale bars, for this is the most common feature when presenting nanoscale structures or nanoscale science. Understanding size and scale is fundamental to learning about nanotechnology as size defines the nanoscale . ...

  11. Noodling Around: Powers of Ten

    21 Jan 2020 | | Contributor(s):: Marilyn Garza, NNCI Nano

    This activity develops a K–12 student’s skills in measurement by using a pool noodle to measure objects. The activity encourages students to consider features that are useful when developing or using a measurement tool. This lesson introduces scale by demonstrating scales as factors...

  12. The Pinch Test: The Right Tool for the Right Object

    21 Jan 2020 | | Contributor(s):: Pamela Gilbert-Smith, NNCI Nano

    This lesson will be used to assess student knowledge of size or SI prefixes and which equipment/tools you would need to view objects of particular sizes. The lesson can be used to see how much students know before teaching; to introduce them to the topic; or to assess what they have learned...

  13. Scale Models: A Size and Scale Activity

    21 Jan 2020 | | Contributor(s):: Marilyn Garza, NNCI Nano

    This lesson introduces scale by demonstrating scales as factors of ten. This facilitates the introduction and reinforcement of the metric scale and paves the way to the discussion of lengths that are smaller than what can be seen with the naked eye. ...

  14. Shrink Me: A Size and Scale Lesson
