In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this activity, learners use their sense of smell to explore the world on the nanoscale.

This hands-on activity shows you how to make a shaker -- a small instrument with a big sound! Fill it with beads or even pennies for a cool sound.

In this activity, young learners use different-sized paper 'caterpillars' and various household items to predict and measure their height.

This guide features three related ramp explorations in which learners investigate the following science concepts: when placed on a ramp, some objects roll, others slide, and others stay put; the shape

In this activity, learners arrange triangles together to make patterns to create paper quilts. Learners experiment with arranging the triangles in different ways to make various designs.

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

This activity gives caregivers and their children an opportunity to practice scientific ways of thinking that are developmentally appropriate for early learners.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
