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).

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

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

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
