Curriculum Overview

This unit consists of five activities designed to help students understand the size and scale of objects.

Activity 1: Scale Models gives students a sense of size and scale using objects that cannot be seen with the naked eye. This activity focuses on measuring length, for this is the most common feature when presenting nanoscale structures or nanoscale science. It can be introduced into the K–12 curriculum by discussing scientific measurement. This activity connects well to the introduction of atoms and cell structures as well as advancements in technology.

Activity 2: Noodling Around: Powers of Ten 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.

Activity 3: Shrink Me! gives students a sense of size and scale using objects that cannot be seen with the naked eye. It is designed to help students understand the size and scale of objects that are shrunk by orders of 10.

Activity 4: The Micro and Macro World Around Us is designed to help students understand the size and scale of objects that can and cannot be seen with the naked eye. It focuses on scale and the importance of using scale bars.

Activity 5: What’s in YOUR Neighborhood? gives students a sense of size and scale using their classroom and their neighborhood as a frame of reference.
