This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

In this design challenge, learners will practice empathy and design thinking skills by creating an invention of the future.

In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

Learners explore the endless possibilities of cardboard engineering in this open-ended STEAM activity. Practice being creative by building structures with no glue, only cardboard and scissors.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this activity, learners make self-assembled polymer spheres.

In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

In this activity, learners investigate how some butterfly wings get their color.

In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.

In this Spanish-language chemistry activity, learners use simple materials to explore how fire extinguishers work to put out fires.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.
