Model Eardrum
Source Institutions
In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.
Smell Match
Source Institutions
In this matching activity (3rd activity on the page), learners use their sense of smell to match pairs of opaque containers filled with various smelly items like orange peel, roses, or moth balls.
Edible Model of the Sun
Source Institutions
In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.
The Jelly Bean Challenge
Source Institutions
In this activity, learners explore how their sense of smell affects their taste buds. Learners taste different flavored jelly beans while holding their nose.
Bake Ice Cream in Your Oven
Source Institutions
In this a hands-on activity, learners explore how to put ice cream in an oven without it melting. Ideas in this activity include insulation and cooking.
Potato Straw
Source Institutions
In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.
Marshmallow Models
Source Institutions
No glue is needed for learners of any age to become marshmallow architects or engineers.
Frog Eggs
Source Institutions
In this activity, learners compare frog eggs to chicken eggs to better understand why frog eggs need water. Learners compare a boiled chicken egg to "frog eggs" represented by boiled tapioca.
Chocolate (Sea Floor) Lava
Source Institutions
In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.
Condiment Diver
Source Institutions
In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.
How to Extract DNA From Anything Living
Source Institutions
In this genetics activity, learners discover how to extract DNA from green split peas.
For the Birds
Source Institutions
In this activity, learners will explore nature by creating food for birds. Learners will develop fine motor skills and engage in nature observation through this activity.
Hot Sauce Hot Spots
Source Institutions
In this activity, learners model hot spot island formation, orientation and progression with condiments.
Casting and Molding
Source Institutions
This activity was designed for blind learners, but all types of learners can explore the process used to cast and mold molten metal, glass, and plastics.
Your Sense of Taste: Discover the real taste of candy
Source Institutions
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.
Cabbage Chemistry
Source Institutions
In this chemistry activity (page 5 of the PDF), learners make an acid-base indicator using cabbage. Learners then explore how various subtances react with this indicator.
Geyser
Source Institutions
This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.
Color-Changing Carnations
Source Institutions
Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.
Spaghetti Bridge
Source Institutions
In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.
Amazing Marshmallows
Source Institutions
In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.
