In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

Learners observe working lava lamps to understand how they work (included in PDF link).

In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

Many people get water from a source deep underground, called groundwater.

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners observe hard parts of sea creatures (shells, molts, etc.) to better understand marine environments.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

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 introduces learners to the structure and properties of carbon nanotubes.

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

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.
