DO NOT CUT OUT THE NOTES!!Copy the following information in the “Structure and Functions of Living Organisms” section of foldable Prokaryote: organism without a nucleusEukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton; have a nucleusA system is a group of organs that work together and provide an organism with an advantage for survival. System levels of organization progress from cells to tissues to organs and then systems. Systems work alone and with other systems to allow your body to maintain homeostasis. Homeostasis is a stable internal environment that allows you (and your cells) to survive.Copy the following information in the “Evolution and Genetics” section of foldableA Punnett Square shows the genotype’s two individuals can produce when crossed (founded by Reginald Punnett)Gregor Mendel: father of genetics; studied pea plantsIn humans, body cells have 46 chromosomes a piece (receive 23 from each parent)The ONLY way for a recessive trait to show up in an organism is if that organism's genotype is homozygous recessive (two little letters, like "rr").Heredity is the passing on of characteristics from parents to offspring and genetics is the study of heredity.A pedigree is a diagram of family relationships that use symbols to represent people and lines to represent genetic relationshipsMeiosis — sexual reproduction; type of cell division where one body cell produces for gametes, each containing half the number of chromosomes in a parent’s body. Ex: fertilization--male (sperm) and female (egg) sex cells come togetherMitosis—asexual reproduction; nucleus undergoes cell division in which 2 daughter cells are formed, each containing a complete of chromosomes Ex: budding—a cell or group of cells pinch off from the parent to form a new individual Copy the following information in the “Energy Conservation” section of foldableMechanical Energy = sum of objects potential and kinetic energy EX: cars’ moving energy or book resting on top of tableThe faster molecules move = more thermal energy Heat is energy transferred from object of higher temp to object of lower temp. (always flows from hot to cold)The Law of Conservation of Energy states that energy cannot be created or destroyed; only transferred from one from of energy to another. (energy transformation)Temperature measured in degrees; thermometer is used to measure temperature- Celsius Scale - most commonly used around the world; water freezes at 0°C and boils at 100°C- Fahrenheit Scale- used in United States; water freezes at 32°F and boils at 212°FA simple machine is a device that makes work easier by changing the size or direction of a force. Compound machines are a combination 1 or more simple machines.Mechanical advantage is the number of times the machine multiplies force.(output force/input force)Ideal Mechanical Advantage (IMA) is what is desired of a machine (usually 100%), where Actual Mechanical Advantage (AMA) is what the machine actually does. A complete circuit is made by a closed path through which an electric current flows or may flow.Copy the following notes in “Forces and Motion” Section of FoldableMotion: a change in position, measured by distance and time.?Frame of reference: the point from which movement is determined. To measure movement, some point must be considered as nonmoving. Earth is the most common frame of referenceVelocity: speed in a given direction. Velocity gives distance, time, and the direction of travel.Force: any push or pull. Forces give energy to objects. Forces cause a change in motion. Friction: a force that opposes motion between 2 surfaces that are touching. Gravity: the force of attraction between all objects in the universe.? Free fall - an object falling under the influence of gravity. Near the surface of the earth all objects are accelerated by gravity at a rate of 9.8 m/s/s Weight: the effect of gravity on an object’s mass (Weight a change due to gravity but mass does not change.)Momentum: the product of the mass of an object and its velocity.All moving objects have momentum. To calculate momentum, use the equation: Momentum = Mass x VelocityAn unbalanced force acting on an object changes its speed or direction of motion, or both. If a force is balanced, it is not moving.Inertia is the tendency of objects to resist any change in motion. Likewise, inertia is the reason a moving object stays in motion with the same velocity unless a force changes its speed or direction or both. Copy notes in the “Earth Systems” section of the foldable3 Ways heat is transferred Conduction- transfer of heat from one object to another through DIRECT CONTACT-warmer object transfers energy to cooler object until equal temp- conductors – transfers heat well like metals- insulators – poor conductors of heat such as wood, paper, and plastic foam- Convection- transfer of heat by movement of liquid or gas- increase of temp causes density of substance to decrease and move upward- Radiation- transfer of energy by electromagnetic waves- Sun is biggest source of radiation heat transferCopy on the back of your foldable:Scientific method steps:1. Define Problem or question2. Gather information3. Form hypothesis4. Plan experiment and identify variables5. Conduct experiment 6. Analyze and organize data 7. Draw conclusions and share results-independent variable- factors that are changed or manipulated in an experiment (goes on X-axis: horizontal);only ONE independent variable per experiment (EX: color of the light bulb) - dependent variable- outcome variable or factor being measured or observed (goes on Y-axis: vertical); EX: growth of plantsGraphs shows data in a visual way and makes it easier to understand the data. ................
