This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

In this activity, learners use measurement concepts to make models of what their body parts might look like if they were a snake or a chameleon.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this quick activity about size and scale (on page 2 of the PDF under What's Nano?

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).
