Tools of Magnification
Source Institutions
In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

Be a Scanning Probe Microscope
Source Institutions
In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano

Atoms and Matter (K-2)
Source Institutions
In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

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

Magnifying and Observing Cells
Source Institutions
In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.

Size and Scale: Probing and Predicting
Source Institutions
In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?
