Radar Mapping: What's in the Box?
Source Institutions
In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

Our Beautiful World
Source Institutions
In this Bob the Builder(TM)-themed activity, learners go on a nature walk outside and describe what they observe using their senses.

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

Exploring Size: Scented Balloons
Source Institutions
In this activity, learners use their sense of smell to explore the world on the nanoscale.

Give or Take?
Source Institutions
In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

Our Chemical Senses: Olfaction
Source Institutions
In this activity, learners investigate the olfactory system by conducting several experiments.

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

Number Sense and Computation: Money Counts
Source Institutions
In this math lesson, learners count and compare amounts of money less than or equal to one dollar.

Number Sense and Computation: To Half or Half Not
Source Institutions
In this math lesson, learners use slices of bread and geoboards to explore several ways to divide a rectangle in half. Learners also identify equivalent fractions that represent one-half.

Our Sense of Touch: Two-Point Discrimination
Source Institutions
In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

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

How Are Soils Classified?
Source Institutions
In this activity about soil (page 7 of the PDF), learners will use their sense of touch as well as sight to understand how soil is classified based on texture and other details.

Silent Stalking
Source Institutions
In this outdoor game, learners role play predator and prey to explore the importance of keen hearing and silent stalking skills in the animal world.

Smelly Balloons
Source Institutions
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.

Mystery Box: Making Observations and Collecting Data
Source Institutions
This activity was designed for blind learners, but all types of learners can use it to learn to differentiate between qualitative and quantitative observations and to practice data collection.

Rumination
Source Institutions
In this activity (on pages 24-34), learners explore the four-part stomach of cows (and other grazing animals called ruminants), and compare it to the human one-part stomach and its digestive process.

Exploring Size: Scented Solutions
Source Institutions
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).

Tasty Visions
Source Institutions
In this activity (5th activity on the page), learners explore how what you see influences taste. In experiment 1, learners taste five sodas, one of which is clear soda with orange food coloring.

Sensational Seaweed
Source Institutions
In this culinary activity, learners use multiple senses (sight, smell, touch, and taste!) to explore real seaweed samples.

Number Sense and Computation: Soak It Up
Source Institutions
In this math lesson, learners compare products to determine the best product.
