In this activity, learners make a model of a one-way heart valve to investigate how a heart controls the direction of blood flow.

In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

In this online activity about heart disease, learners will, with the virtual help of an actual surgeon, watch a virtual bypass surgery.

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

Learners construct a bracelet containing two strands of beads, which represents a double strand of DNA that codes for a gene. They match beads to the bases in a section of a chimp's DNA code.

In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.

This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

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

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

This is an activity about acid-base reactions using eggs and vinegar. Learners place eggs inside a container of vinegar and leave to soak overnight.

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

Learners will explore the chemistry of mucous and its importance to our health by following a process to make their own replica "snot." The activity includes a time and age recommendation, a materials

In this activity, learners model a population of deer and see how the number of deer changes over time.

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

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 activity, use standard playing cards to introduce learners to cellular interactions such as cell to cell recognition and signal and receptor specificity.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

In this activity, learners will create a home for animal friends in their backyard using recycled materials. Some material suggestions include: pine straw and twigs.

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