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

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

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.

In this activity, learners work in groups to create a time line representing significant moments in their lives.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

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 activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

In this activity, learners examine nanoscale structures of common things.
