This lesson focuses on how materials behave differently as their surface area increases.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

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 confront their perceptions of gravity in the solar system.

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

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners model the gravitational fields of planets on a flexible surface.

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

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this lesson, learners cut paper into very small pieces to explore the small size of quarks, the smallest thing we know of on Earth.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

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).

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

In this activity, learners examine the culture and history of the tomb site.

In this activity, learners place cards featuring biological structures in order by their relative size from largest to smallest.

Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.
