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
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.

Flow of energy 2013-2014
1. Energy from the sun is stored by producers like plants through photosynthesis and stored as glucose. Producers are then eaten by primary consumers like herbivores. Higher-level consumers like carnivores eat those primary consumers.
2. Food chains and food webs show the transfer of energy between organisms in an ecosystem. Food chains show a single pathway while food webs show the complex interconnected feeding relationships.
3. Energy pyramids illustrate that only about 10% of energy is transferred between trophic levels, so the amount of energy decreases at each higher level. Producers form the base and consumers occupy higher levels.

H r diagram
Stars can be classified based on their size, temperature, and brightness. A star's temperature determines its color, with red stars being cooler and blue stars being warmer. A star's apparent brightness depends on both its true luminosity and its distance from Earth, while absolute brightness represents luminosity alone. Scientists map stars' temperatures and absolute magnitudes on a Hertzsprung–Russell diagram to study stellar evolution.
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!
Light Years Notes
This document defines and provides examples of light years, which are used to measure the vast distances in space. A light year is the distance that light travels in one year, which is approximately 5.88 trillion miles or 9.5 trillion kilometers. When viewing stars and other objects in space, we are seeing them as they appeared in the past due to the time it takes their light to reach Earth, such as light from Sirius taking 8 years to reach us.

Force & motion notes 2014 2015
This document discusses forces and motion. It defines key terms like force, net force, balanced and unbalanced forces. It explains that an object's motion can only be determined relative to another object used as a reference point. Forces can be added or subtracted depending on whether they act in the same or opposite directions. A net force causes an object to change its motion, such as starting to move, stopping, or changing direction. Balanced forces in opposite directions do not change an object's motion.

It then describes the major components of the human digestive system from mouth to anus. Key functions and processes at each stage are highlighted, including mechanical and chemical breakdown of food. Absorption of nutrients primarily occurs in the small intestine. Undigested material then passes to the large intestine where water is absorbed before waste is excreted.
Exp design water notes 2014
Scientific research and discoveries have significantly improved modern life. Key scientists like Copernicus, Newton, Curie, and Pasteur made contributions that changed our understanding of physics, chemistry, and medicine. Without scientific advances, we would lack many modern technologies and medical treatments. Proper water filtration is also important, as unsafe water can spread disease. Filters work by using porous materials to remove particles from water through permeability and percolation. Understanding water's physical properties helps design effective filtration systems.
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.
Staar warm ups 1
The document contains several short science passages and multiple choice questions about topics like:
- The physical and chemical processes of human digestion.
- Representations of molecules and elements in chemical equations.
- Evidence of chemical reactions like burning sugar producing a gas.
- The conversion of mechanical to electrical energy by a wind turbine.
Chicken wing dissection
1. The document provides instructions for a lab on dissecting a chicken wing to learn about the musculoskeletal system. It discusses how dissection can teach students about human anatomy by examining similar structures in other animals.
2. The lab covers safety procedures for handling raw chicken and cleaning up. It then guides students through dissecting a chicken wing to observe muscles, tendons, bones, joints, and how they work together to allow movement.
3. Key structures that are identified and their functions explained include the bicep and tricep muscles that lift and lower the arm, tendons that connect muscles to bones, ligaments that connect bones at joints, and cartilage in joints that provides a slippery surface for
