Extraterrestrial life
This document discusses theories of extraterrestrial life over history and current scientific research on the topic. It describes how Greek philosophers first proposed the possibility of life on other planets. NASA researchers claim to have found evidence of ancient life in a meteorite from Mars. Scientists also believe Europa and planets discovered by the Kepler satellite could support life as they seem to meet the basic prerequisites of liquid water and sources of energy. While no conclusive evidence of extraterrestrial life has been found, ongoing studies have made the possibility more plausible.
Search For Extraterrestrial Life
NASA and other space agencies are searching for signs of extraterrestrial life by looking for bacteria and organic molecules on planets and moons that show evidence of once having liquid water. The Viking landers tested Mars for life in 1976 but found no conclusive evidence. The Phoenix lander searched the Martian arctic for organic molecules and water ice in 2008. The Hubble Telescope has detected methane, an organic molecule, in the atmosphere of planets orbiting other stars, which could indicate the possibility of life. Europa and Enceladus, moons of Jupiter and Saturn, are also prime targets in the search due to evidence that they may harbor subsurface oceans.
A new framework to test the origins of western American megadrought
We know from tree rings and other natural drought records that the western United States has been affected by several 'megadroughts' during the past millennium. But are these exceptionally long-lasting droughts due to unusual external forcings, or are they inevitable given a sufficiently long period of time? Here we present a statistical model that combines sea surface temperature records and drought severity statistics from the western USA, and use that tool to set out an expectation for megadrought, given no other changes in the climate system. Even though this model was trained using only modern climate data (and incorporates no information from tree rings or other proxies), it still produced megadroughts. Moreover, those simulated megadroughts were just as long-lasting, covered as large an area, and were just as severe as real megadroughts estimated from tree rings. That result means that megadroughts can occur in the western United States even if nothing else changes in the climate -- they really are just a matter of time. On the other hand, the only aspect of real-world megadroughts that the model cannot duplicate was the high number of these events during the so-called Medieval Climate Anomaly (800 to 1300 CE). So that cluster of megadroughts may have been caused by some sort of unusual climate circumstances that have not been observed by us during the past few decades. The proxy record tells us that many different kinds of exceptional or unusual climate events happened in the past. But it is often difficult to determine what caused those exceptional events because even, within a period of a thousand years, we still have very few cases. So besides being an aid to understand the causes of past megadroughts, we hope this approach can be applied to other paleoclimate records to distinguish between real interrelations between separate components of the climate system and simple coincidences.

Keplers law
Kepler's three laws of planetary motion are summarized as follows:
1) Kepler's first law states that planets move in elliptical orbits with the Sun located at one focus.
2) His second law describes that a radius vector between the Sun and a planet sweeps out equal areas in equal times.
3) Kepler's third law specifies that the square of a planet's orbital period is directly proportional to the cube of the semi-major axis of its orbit.
New discovery
1. Astronomers detected a planet orbiting Proxima Centauri, the star closest to our sun, that is 1.3 times the mass of Earth and sits within the star's habitable zone.
2. Scientists from LIGO detected gravitational waves from the collision of two black holes over a billion years ago, confirming Einstein's theory of relativity.
3. Archaeological discoveries in Australia have shown that humans have inhabited the continent's interior for at least 49,000 years, 10,000 years longer than previously thought.

2014 Genes and Heredity
This document summarizes key concepts in genetics and heredity. It discusses Gregor Mendel's experiments with pea plants that revealed the laws of inheritance. Mendel discovered that traits are passed from parents to offspring through discrete units called genes located on chromosomes. Genes come in different forms called alleles that can be dominant or recessive. A Punnett square can be used to predict the possible combinations of alleles and the traits that may be expressed. Sexual reproduction involves two parents and produces offspring with a mix of parental traits, while asexual reproduction requires only one parent and produces identical offspring. Charles Darwin's theory of natural selection explains how organisms with traits better suited to their environment are more likely to survive and reproduce, passing on

The expectations are that the illustrations will be in color and writing will be in pencil or ink. Various due dates are provided for different components of the assignment.
Cell structure 2013
Plant and animal cells contain organelles that carry out essential functions. Key organelles include the nucleus, which controls cell activities, mitochondria which generate energy, and the cell membrane which regulates what enters and exits the cell. Plant cells additionally contain a cell wall, chloroplasts for photosynthesis, and larger vacuoles for storage. While organelles vary in shape and function, they work together within cells to keep organisms alive.
Watershed Lab 2013
A watershed is defined as the land area that drains into a particular water body. During rainstorms, water flows over land as runoff and collects in streams, rivers, and other channels, with the entire land area draining into these waterways comprising the watershed. Watersheds resemble branching tree patterns as tributaries flow into streams and streams join together to form larger rivers. Pollutants from cities, factories, roads, and other sources are carried by runoff during rainstorms and drain into waterways, mixing together as they flow through the watershed from higher to lower elevations.

Chemical interactions between Saturn’s atmosphere and its rings
Past remote observations of
Saturn by Pioneer 11, Voyager 1 and 2, Earthbased
observatories, and the Cassini prime and
solstice missions suggested an inflow of water
from the rings to the atmosphere. This would
modify the chemistry of Saturn’s upper atmosphere
and ionosphere. In situ observations
during the Cassini Grand Finale provided an
opportunity to study this chemical interaction
Chapter 18 Lecture
The chapter discusses the history of life in the universe from its beginnings through cosmic evolution. Key stages included the formation of amino acids on Earth and possibly in space, as well as the first single-celled organisms appearing around 3.5 billion years ago. Other places in the solar system like Mars, Europa, and Titan could potentially harbor life. While the Drake equation estimates the number of intelligent civilizations in our galaxy, many of its factors are uncertain, so the nearest technological civilization is likely hundreds of lightyears away. We have sent probes into space carrying information and our radio broadcasts leak signals, while actively listening for messages at the "water hole" frequency.

Nervous System
Here are the steps for the reaction time lab activity:
1. The stimulus is the dropping of the meter stick.
2. The response is catching the meter stick.
3. The variable being measured is reaction time, as determined by the distance the meter stick falls before being caught.
4. The right and left hand reaction times may differ due to handedness - most people tend to be faster with their dominant hand due to more practice with fine motor skills.
5. Record the data from each trial in a table and calculate the average distance for each hand to determine which hand has the faster overall reaction time.
Let me know if you need any clarification or have additional questions!

2013 respiratory system pdf
The respiratory system brings oxygen into the body and removes carbon dioxide through a series of organs including the nose, pharynx, larynx, trachea, bronchi, bronchioles and alveoli. Air enters the nose and mouth, and is transported through the respiratory tract to the alveoli where gas exchange occurs through diffusion. The diaphragm and rib muscles work together to inhale and exhale air during breathing.
circulatory system
The circulatory system consists of the heart and blood vessels that circulate blood throughout the body. The heart pumps blood through a network of arteries, capillaries and veins. Arteries carry oxygenated blood away from the heart while veins carry deoxygenated blood back to the heart. Capillaries connect arteries and veins and allow for the exchange of oxygen, carbon dioxide and other materials between the blood and tissues. The circulatory system circulates blood an average of once per minute to deliver oxygen and nutrients to tissues and remove carbon dioxide and waste.
