    A short video clip is used as the hook for the lesson. The clip highlights the "strange properties" that happen at the nanoscale. In this lesson, students explore how properties change with size through a series of experiments. The students work in small groups to answer questions about what they observe. After completing the experiments, the teacher leads a discussion in which the class generalizes the findings of the activities. Analytical reasoning will be used to develop explanations for why these effects occur. Direct instruction on the unique properties of the nanoscale and the models that explain behaviors ends in analysis of a graphic organizer that displays the key ideas of this lesson.

    Generation Science Standards.Standards (NGSS; Achieve, 2013). The 2013
    Specific reference to nanotechnology is found in the Virginia Standards of Learning. "Nanotechnology is the study of materials at the molecular (atomic) scale. Items at this scale are so small they are no longer visible with the naked eye. Nanotechnology has shown that the behavior and properties of some substances at the nanoscale (a nanometer is one-billionth of a meter) contradict how they behave and what their properties are at the visible scale. New discoveries based on nanoscience investigations have allowed the production of superior new materials with improved properties (e.g., computers, cell phones). Recognize examples of the use of nanotechnology and its applications." (VADOE, 2010)
    This unit extends content beyond the NGSS performance expectations in Physical Science beyond the identification of materials by their properties (e.g. 5-PS1-3 http://www.nextgenscience.org/5ps1-matter-interactions and MS-PS1-2 http://nextgenscience.org/msps1-matter-interactions ). Students explore the scientific models that explain behavior at the nanoscale and compare these models to the models that explain behavior at the visible scale.

    The curriculum components include: lesson plans, embedded video clips, links to supporting websites, supplementary reading materials for students and the teacher, and masters of all handouts referred to in the lesson plans.
    Each lesson has detailed descriptions to aid teacher implementation including notes to alert the teacher to prerequisite knowledge that may need to be reviewed and the rationale/purpose for each activity.
    The unit will behas been field-tested in January. After field-testing,and revisions will behave been made.
