Experience the Exploratorium at Pier 15
WEBExperience the Exploratorium. Let your curiosity roam free through hundreds of exhibits in our six spacious indoor and outdoor galleries at Pier 15, San Francisco.
Secret Language: Cryptography & Secret Codes | Exploratorium
WEBDownload the PDF file containing the cipher wheels.; Copy and cut out the two wheels. Place the smaller wheel on top of the larger wheel and rotate them so your "key letter" on the small wheel is beneath the "A" of the large wheel.
A Brief History of Pi (π) - Exploratorium
WEBLearn about the long and rich history of π. Pi (π) has been known for almost 4000 years—but even if we calculated the number of seconds in those 4000 years and calculated π to that number of places, we would still only be approximating its actual value.
Origins: CERN: Ideas: The Big Bang - Exploratorium
WEBFor a brief moment after the Big Bang, the immense heat created conditions unlike any conditions astrophysicists see in the universe today. While planets and stars today are composed of atoms of elements like hydrogen and silicon, scientists believe the universe back then was too hot for anything other than the most fundamental particles -- such as quarks and photons.
Anatomy of an Egg - Exploratorium
WEBShell. Bumpy and grainy in texture, an eggshell is covered with as many as 17,000 tiny pores. Eggshell is made almost entirely of calcium carbonate (CaCO 3 ) crystals.It is a semipermeable membrane, which means that air and moisture can pass through its pores.
Your Weight on Other Worlds | Exploratorium
WEBMass and Weight. Before we get into the subject of gravity and how it acts, it's important to understand the difference between weight and mass.. We often use the terms "mass" and "weight" interchangeably in our daily speech, but to an astronomer or a physicist they are completely different things.
Science of Eggs: Egg Science | Exploratorium
WEBEgg proteins change when you heat them, beat them, or mix them with other ingredients. Understanding these changes can help you understand the roles that eggs play in cooking. Proteins are made of long chains of amino acids. The proteins in an egg white are globular proteins, which means that the long protein molecule is twisted and folded and curled up into a more or less spherical shape.
Naked Egg: Biology & Chemistry Science Activity | Exploratorium
WEBDay 1. Use a scale to find the mass of each de-shelled egg before treatment. Record the result on notepaper. Place one egg in a labeled container and cover it with your chosen treatment.
Total Solar Eclipse 2024 Time & Path | Exploratorium
WEBBe with an astronomer. Find someone who has a telescope and knows how to use it. You can watch the eclipse with your eclipse glasses, but a telescope—with the proper, safe filter!—will make viewing the eclipse even more amazing. If you don’t have a buddy with a telescope, check at your local library or museum for special events.
Build a Solar System Model | Exploratorium
WEBOne of the most exciting exercises I ever did as a kid was to make a scale model of the Solar System. Most of the pictures in my books made the distance between planets seem small and easy to travel.
