O-H!
Title: O-H!
Prepared by: Craig Montgomery
Background
The Ohio State University was founded in 1870, football was established at the university in 1890. Ten undefeated seasons, eight national championships, twenty-five bowl wins, and six Heisman Trophy winners are just a few of the accolades in the Buckeye’s history.
Newton's First Law
The first law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted on by another force.

Quest For Fire
Title: Quest for Fire
Background:
One of humankind’s greatest achievements was the ability to control fire thousands of years ago. Fire enabled our early ancestors to cook food, light the dark, and keep warm.
For combustion to take place, three things must be present:
1. Fuel - the substance that burns, e.g. wood, oil.
2. Oxygen - when a fuel is burned it is reacting with the oxygen in the air.
3. Heat - this ignites the fuel and keeps the fire burning.
This can be represented in a diagram known as the Fire Triangle:

Let it Snow
Background:
A snowflake begins to form when an extremely cold water droplet freezes onto a pollen or dust particle in the sky. This creates an ice crystal. As the ice crystal falls to the ground, water vapor freezes onto the primary crystal, building new crystals – the six arms of the snowflake.

Ancient Geometry-Name the Shape
|
Background:
From about 200 BC to AD 500, the Ohio River Valley was a focal point of the prehistoric Hopewell culture. The culture is characterized by the construction of enclosures made of earthen walls, often built in geometric patterns, and mounds of various shapes. The most striking Hopewell sites contain earthworks in the form of squares, circles, and other geometric shapes. Many of these sites were built to a monumental scale, with earthen walls up to 12 feet high outlining geometric figures more than 1000 feet across. Conical and loaf-shaped earthen mounds up to 30 feet high are often found in association with the geometric earthworks. Below are maps of the Newark Earthworks and High Bank Works near Chillicothe. Both Newark and Chillicothe were significant sites of mound building and were probably once connected by parallel mounds that formed a road the length of the seventy miles between the two sites. Time to think: Using the two maps, what geometric shapes can you identify? What similarities do you see between the two sites? What differences? The Great Circle in Newark is nearly 1200’ in diameter; how do you think the Hopewell created a circle that large 2,000 years ago? How do you think they built two nearly identical features, a circle with a conjoined octagon, nearly seventy miles apart from each other? |
