In this activity, learners smell bottles containing bee pheromone molecules (or herb/spice extracts as a substitute). Bees release these molecules to send messages to each other.

In this activity, learners explore how their sense of smell affects their taste buds. Learners taste different flavored jelly beans while holding their nose.

In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

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

In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.

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

This activity (on page 3 of the PDF under GPS: Animal Scent Activity) is a full inquiry investigation into animal behavior.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this two-part activity, learners use household items to smell the difference between some stereoisomers, or molecules which are mirror images of one another.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

In this wintertime outdoor activity, learners role play wolves tracking their prey by following scented trails.

In this matchmaking activity (on page 2 of the PDF under GPS: Animal Scent Activity), learners will each have a scented cotton ball taped to their shoulder. The scent (e.g.

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 outdoor, sensory activity, learners role play as animals trying to identify their "family's" scent and locate their "territory." Learners mark their territories and sniff out other territories

In this activity, learners use household materials to investigate and explore their ability to smell an odor.

In this activity about olfaction (8th activity on the page), learners smell 10 different items with different odors. Then they try to identify the smells when they are mixed together.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

In this activity about olfaction (7th activity on the page), learners use natural ingredients to concoct their own perfume.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.

In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.
