    Does Size Matter? Measurements & Nanoscale

    Does Size Matter? Measurements & Nanoscale

    Overview

    This short mini-lesson is designed to be used by any science instructor teaching the International System of Measurements (SI).  It will introduce students to the concept of nanoscale.

    Standards

    Biology Standards(Indiana): B.2.2, B.5.1, B.5.3

    Learning Objectives

    Students will classify and catorgorize objects based onsize, including nanoscale.

    Students will identify the most commonly used units of measure in Biology.

    Materials

    10 pictures of items across the SI units scale

    Student handout with blanks for drawing items across SI scale and include blanks for SI units that will be used during course.

    Procedure

    Do Now:

    1. What is the smallest item you have ever seen?
    2. What technology can be used to see items that aren’t visible to the naked eye?
    3. In your own words define nanotechnology and site reference.

    Demonstration

    Handout pictures of items to 10 students in class and allow them to arrange themselves (with input from class) from largest to smallest. If space allows, draw a size scale on board for student placement. Distribute handouts for all students to draw items on the scale. Discuss the SI units (with examples) that are used for volume, length, mass, temperature, and time while students take notes on the handout.

    Exit Ticket:

    1. What is nanotechnology?
    2. Name 3 applications of nanotechnology?
    3. What are the standard units of measurement for volume, length, and mass?
