This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume.

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 discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r

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.

In this activity, learners use their imaginations and experiment with different materials to create bug hats.

In this activity, learners work in teams to study the observation skills essential to scientific research.

In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.

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

Your tongue can sense about 6 different flavors (salty, sweet, bitter, sour, umami/savory, and fat), but your nose provides a lot more "taste" information than you realize when you eat.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

In this activity, learners investigate the olfactory system by conducting several experiments.

Learners complete a series of hands-on and investigative activities to explore cumulus clouds.

In this activity about olfaction (9th activity on the page), learners smell 10 different items with different odors, including some edible food items.

In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e
