Cookie Subduction
Source Institutions
This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.

Oreo Phases
Source Institutions
In this activity, learners recreate the lunar phases using the frosting from Oreo® cookies and place the phases in order. Round cream cheese crackers can also be used if cookies are not an option.
Pepper Scatter
Source Institutions
In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

Toast a Mole!
Source Institutions
In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

Making Waves
Source Institutions
Investigate the interaction of liquids of different densities and experiment with wave patterns with this hands-on activity.

Single Serving Volcanism
Source Institutions
In this activity, learners eat a snack and make a model of the plumbing system of a volcano.

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.

Chocolate Lava
Source Institutions
In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

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.

Hot Sauce Hot Spots
Source Institutions
In this activity, learners model hot spot island formation, orientation and progression with condiments.

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.

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.

Dinosaur Homes
Source Institutions
In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

Soda Pop Cave
Source Institutions
In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

Comparing Crystals
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

What's the Difference between Weather and Climate?
Source Institutions
In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

An Apple as Planet Earth
Source Institutions
In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.
Why is the Sky Blue?
Source Institutions
In this activity, learners create a "mini sky" in a glass of water in a dark room.

Space Jell-O
Source Institutions
Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

Make An Impact
Source Institutions
In this hands-on activity, learners simulate the crashing and smashing of a meteor impact using household cooking supplies.
