Anatomy of an Egg - Exploratorium
WEBBumpy 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. The shell also has a thin outermost coating called the bloom or cuticle that helps keep …
Cow's Eye Dissection - Exploratorium
WEBThis works because the lens in your magnifying glass is carefully shaped to bend light in a particular, predictable way. The lens is shaped to bend light rays so that they come together and then spread apart to make an image.The lens of your magnifying glass is probably fat in the middle and thin at the edges.
A Brief History of Pi (π) - Exploratorium
WEBHere’s a brief history of finding π. The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for π, which is a closer approximation. The Rhind Papyrus (ca.1650 BC) gives us insight into the ...
Build a Solar System Model | Exploratorium
WEBIf you build your solar system on a roll of toilet paper, you can make the Sun about .4 inches (10 mm) across and still fit the entire solar system on the roll. A standard roll of toilet paper has about 450 sheets that are about 4.375 inches long, hence the roll is about 164 feet long. You should check your toilet paper for length.
Your Weight on Other Worlds - Exploratorium
WEBScales measure the force of attraction between you and the Earth. This force of attraction between you and the Earth (or any other planet) is called your weight. If you are in a spaceship far between the stars and you put a scale underneath you, the scale would read zero. Your weight is zero. You are weightless.
What Causes a Solar Eclipse? | Exploratorium
WEBA solar eclipse occurs when the moon passes between the Sun and Earth, casting the moon's shadow on Earth. This only happens occasionally, because the moon doesn't orbit in the exact same plane as the Sun and Earth do. Two things need to occur at once for you to see a solar eclipse: the Sun, moon, and Earth need to be in a straight line, with ...

Science of Bread: Bread Science 101 - Exploratorium
WEBThis organism lies dormant until it comes into contact with warm water. Once reactivated, yeast begins feeding on the sugars in flour, and releases the carbon dioxide that makes bread rise (although at a much slower rate than baking powder or soda). Yeast also adds many of the distinctive flavors and aromas we associate with bread.
