It was armed with a single torpedo tube and one dynamite gun to use against enemy ships. The USS Holland was the basis of the propulsion system for many years to come. A year later, Simon Lake followed up the USS Holland with a bigger, more advanced submarine called the “Protector”. This submarine was the first to incorporate a light infrastructure to improve the overall seakeeping qualities of the vessel. Also, the submarine was equipped with the first ever airlock for divers to exit and enter the ship.
The word, tattoo originates from the Tahitian word tattau, which means, "to mark" and was first mentioned in explorer James Cook's records from his 1769 expedition to the South Pacific. However, some scientists believe that the earliest known evidence of tattooing dates back to markings found on the skin of the Iceman, a mummified human body that dates as far back as 3300 B.C. Tattoos have came a long way since then. People get tattoos every single day whether it’s a portrait an animal or their favorite sports teams’ logo people love tattoos. When getting a tattoo there are many things to look at and look for when choosing the right parlor.
Robert Hooke's most famous scientific work was his book Micrographia, which he published in 1665. This book is a collection of observations from his homemade compound microscope and illumination system. He observed not only plants but also many types of life from insects, sponges, and microorganisms all the way up to bird feathers. In conclusion, Robert Hooke was probably the single greatest experimental scientist to come out of the seventeenth century. He was one of the most diverse of all scientist of his time contributing major findings to almost all fields of science.He was an natural philosopher, architect and polymath who played an important role in the scientific revolution, through both experimental and theoretical work.
May 21- July 31 We started upstream on the Missouri River from the St Louis area camp. We had been preparing for the expedition since fall of last year. Me and nearly four dozen other men met up with Meriwether Lewis. We started making our way up the Missouri on a fiftyfive foot long keelboat and two smaller pirogues. As we traveled, I spent most of his time on the boat, charting the course of our journey and mapping it out the river and such, while Meriwether was often ashore studying the landforms, animals, and plants.

Which view of geography do his remarks on the island best support? A Most people use ____ to find places. B What kind of geographic observation is this penguin using? A An environmental specialist may advise governments on ways to protect the environment.
My independent variable is the green crab, which I added to the tide pool off the Washington State coast. My dependent variable was the coral weed because it is affected by the green crab. I started my experiment at 0 crabs/sq. ft. I replicated this step 5 times (resetting the simulation between each replication) and measured the population of the green grab and the coral weed at the end of each repetition.
The Challenger was a space shuttle of great experience. Before its last journey it had witnessed the first steps of man and the first woman on the moon. It was named after the British Naval research vessel that sailed the Atlantic and Pacific Ocean during the 1870’s. The Challenger certainly made its scientific contribution to the sense of exploration because the Apollo 17 also carried the name Challenger (Space Shuttle Overview: Challenger n.p.). The next and last journey of the space shuttle was on January 28, 1986 when the US Space Challenger broke apart seventy-three seconds after lift off.
Christopher Columbus was a navigator, colonizer, and explorer whose voyages across the Atlantic Ocean led to general European awareness of the American continents in the Western Hemisphere. His historical findings changed our scientific understanding of the natural world. We acknowledge the spherical Earth, the use of the trade winds, and new plant and animal life he introduced to the “New World.” During his lifetime, Columbus led a total of four expeditions to the New World discovering many of the Caribbean islands, the Gulf of Mexico, and the South and Central America main lands. On October 12, 1492, after a thirty-three-day voyage from the Canary Islands, Columbus landed in San Salvador in the eastern Bahamas. He thought San Salvador was
Back then, the eastern part of New York was bordering the Atlantic Ocean which was filled with a plethora of corals, clams, and sails. Many of these creatures built their shells from calcium carbonate, which they gathered from the waters around them. The deposits of these creatures’ remains built up over time and the pressure built up. Finally, the lower layers
Geo 202 Ichthyosaurs Ichthyosaurs, the Greek word for fish lizard, were a marine animal far from what its name implies. They played the role of what whales, seals, and dolphins play in today’s marine ecosystem. From fossil records, geologists can tell a lot about the life ichthyosaurs lived throughout the years it roamed the seas, including their body structure, how they reproduced, what they ate, where they lived, and much more including their extinction. Based on fossil evidence, the ichthyosaur first appeared around 245 million years ago. Although earlier forms had a sleek, lizard like body, most had a body structure that most resembled modern day mammals (Perkins).
