Our Solar SystemThe Sun is by far the most massive object in the Solar System, therefore gravitationally dominating all other members of the Solar System. The Sun is a star that gives off radiant energy that drives Earth systems and is essential for life. The Solar System consists of comets, asteroids, planets, and their respective satellites, most of which orbit the Sun on a plane called the ecliptic. The planets in our Solar System revolve in the same direction around the Sun in elliptical orbits that are very close to being in the same plane.

The distance between two adjacent crests is the wavelength. The wave height or wave amplitude is the distance from the crest to the trough. The wave frequency is the number of waves that pass a given point each second. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 2 EarthquakesAn earthquake is the result of a release of stored energy in the Earth's crust that creates seismic waves. Seismographs are machines that detect and measure seismic waves caused by earthquakes. P waves, or primary seismic waves, are the fastest moving waves. They travel through solids, liquids and gases. S waves or secondary waves are slower and can travel through solids, but not liquids. The slowest and most destructive seismic waves are called surface waves. Read more...iWorksheets: 3Vocabulary Sets: 4 FossilsAncient life forms have been preserved, in part and in whole, in the rock record. These preserved pieces of ancient life forms are called fossils. Fossils found in limestone are usually formed by a process called cast and mold. Petrified wood is formed by a process called petrification. In very hot, arid environments, flesh can be dried out and preserved indefinitely. This process is called mummification. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 2 Geologic timeAge of the Earth is 4.6 billion years. Geologic time scale is a map that divides Earth history into logical segments of time. The geologic time scale is broken into divisions and subdivisions. The divisions are called eons. Eons are divided into eras, eras are divided into periods, and periods are divided into epochs. Read more...iWorksheets: 5Study Guides: 1 MineralsA mineral, by definition, must meet four criteria. It must: be a naturally occurring substance, be a solid substance, have an internal crystal structure and have been formed by inorganic processes (in other words, it cannot be formed by an organism). A rock, by comparison, is composed of one or more minerals or organic material (such as coal). Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 3 Plate tectonicsThe Earth is a dynamic planet. Its interior is actually in motion! The crust on its surface is also in motion. It was not until the 20th century that geologists truly began to understand Earth's dynamic movements.

Read more...iWorksheets: 3Vocabulary Sets: 3 VolcanoesEarth's crust is fractured into 13 major and approximately 20 total lithospheric plates. Most of the Earth's volcanoes are located at lithospheric plate boundaries. The belt of volcanoes along the boundary of the Pacific Ocean is called the Ring Of Fire because it contains about 75% of the world's active volcanoes. Why does a volcano erupt? When magma rises towards the surface, gas bubbles expand and increase in pressure. The force of the gas pushes the magma out of the vent and causes an eruption. Read more...iWorksheets: 3Vocabulary Sets: 3 Understanding WeatherThe global winds in the Northern hemisphere curve to the right. The global winds in the Southern hemisphere curve to the left.

Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 7 Circulation and immunityThe circulatory system, otherwise known as the cardiovascular system, consists of the heart, blood vessels, and blood. The heart has two separate sides, the right and left, which are separated by the septum. The septum prevents oxygen-rich blood from mixing with oxygen-poor blood. The valve prevents blood from flowing backwards in the one-way direction of the circulatory system. There are three types of blood vessels in the human body: arteries, capillaries, and veins. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 7 Respiration and excretionAir travels through the nose, pharynx, trachea, and the bronchi within the lungs. Oxygen is gained by the respiratory system and glucose is gained from the digestive system. Both the oxygen and glucose are transported around the body by the circulatory system. With every breath, we pull oxygen out of the atmosphere. The atmosphere consists of 78% nitrogen, 21% oxygen, and 1% other gases, so the air that we breathe is not all taken into the body. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 4 The Digestive System & NutritionThere are six different types of nutrients that the body needs. They are carbohydrates, fats, proteins, minerals, vitamins, and water. There are three main functions of the digestive system. They are to break down foods into molecules that the body can use, absorb the molecules into the blood and send them all throughout the body, and eliminate wastes from the body. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 5 The Endocrine system and ReproductionThe endocrine system controls long-term and short-term changes of the body and many of the daily activities of the body. The system is made up of glands, which are organs that produce and secrete chemicals. Endocrine glands release chemicals called hormones into the bloodstream, which will then be carried throughout the body. The hypothalamus is a small part of the brain that links the nervous system and the endocrine system together. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 5 The nervous systemThe nervous system gathers information from inside and outside of the body, responds to the information that it gathers and helps to maintain homeostasis. There are three different types of neurons: sensory neurons, interneurons, and motor neurons. The three different types of neurons will work together to carry messages all throughout the nervous system. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 6 The Evolution and interaction of Living ThingsOver 3.5 billion years ago, the Earth was much different than it is today.

The gases in Earth's atmosphere include: Nitrogen - 78 percent, Oxygen - 21 percent, Argon - 0.93 percent, Carbon dioxide - 0.04 percent,
Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 2 Modern GeneticsThe main function of a gene is to regulate the production of proteins within cells. Proteins establish the phenotype, physical characteristics, and many other traits of a particular organism. Recall from Topic 5 that DNA is made up of 4 different nitrogen bases, Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 6 Heat and heat technologyAll matter is made up of particles that vibrate with kinetic energy. This movement of particles occurs even when the temperature goes well below zero. When we use the term temperature, we are referring to the amount of thermal energy that a substance has. Thermal energy is the sum of the energy of the moving particle and the potential energy of the resting particles. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 1 The energy of wavesWhen a disturbance transfers energy from one place to another, this is referred to as a wave. Most waves, except for electromagnetic waves, require a substance or medium through which they can travel. This medium could be a solid, liquid or vapor like air. Waves requiring a medium are called mechanical waves. Amplitude: the maximum distance that the medium particles move away from their resting position when a wave is passing through. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 2 Forces in fluidsPressure is calculated by dividing force by area and is measured in units called pascals. For an example, if a force of 10 newtons was exerted over an area of 2 square centimeters, the pressure would be 5 pascals. In fluids, which are substances that can flow, pressure is the sum of each of the forces of each particle in the fluid. Examples of fluids include liquids such as water and gases such as air and helium. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 2 LightWhen light hits an object, it either goes through easily, partially, or not at all. An object that lets most of the light through is said to be transparent. The colors we see depend upon which wavelengths of visible light get reflected back to our eyes. Objects appear white when they reflect all of light’s wavelengths and conversely, they look black when they reflect little or none of the wavelengths. This is why it is wise to wear light-colored clothing in the summer; your clothing doesn’t absorb the light. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 2 Mirrors and lensesThe reflection of light can occur in different ways. Since a mirror has a very smooth surface, all the light bouncing off of a mirror reflects in a regular manner. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 2 SoundSound is a type of longitudinal wave. As it travels through its medium, the mediums particles show areas of compression and rarefaction. Sound, at room temperature, normally travels at a speed of 343m/s. At different temperatures, sound travels at different speeds. The speed of sound is also influenced by the density and elasticity of the medium. When the frequency of sound changes as its source moves in relationship to someone listening, this is called the Doppler Effect. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 2 Chemical bondingFreeChemical bonding involves only an atom's outermost electrons.

States of MatterThere are Four states of matter observable in everyday life: solid, liquid, gas, and plasma. Matter in the solid state has a fixed volume and shape, with component particles (atoms, molecules or ions) close together and fixed into place. Matter in the liquid state has a fixed volume, but has a variable shape that adapts to fit its container. Its particles are close together but move freely. Matter in the gaseous state has both variable volume and shape, adapting both to fit its container. Its particles are neither close together nor fixed in place. Matter in the plasma state has variable volume and shape. Read more...iWorksheets :3 RI.RST.6-8. Reading Standards for Literacy in Science and Technical Subjects
