Our Solar SystemSolar systems begin in the dust and gas clouds found in between the stars. The dust is composed of elements like iron and carbon. The gas is hydrogen and helium. These dusty clouds are called nebulae. Here these particles start to come together to form planets.

As viewed from space, the Earth rotates counter-clockwise. This is called prograde rotation. Planets that spin clockwise are said to have retrograde rotation. Read more...iWorksheets: 4Study Guides: 1Vocabulary Sets: 5 Agents of Erosion and DepositionFreeForces of weathering and erosion are constantly reshaping Earth's surface. Erosion includes the chemical and physical breakdown of rocks and their transport from their point of origin to another location. Blowing wind, running water, flowing ice and and gravity are the forces that erode rock and sculpt the landscape. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 4 Weathering of rocks and soil formationWeathering is a collection of natural processes that, over time, break large rock into smaller and smaller pieces. Rocks can be broken down by physical processes (called mechanical weathering) and chemical processes (called chemical weathering). Soil is a combination of decomposed rock and organic materials. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 4 Exploring the Oceans/OceanographyFreeThe oceans are highly comples environments. The oceans consist of different zones and habitats. As one moves deeper, the amount of light decreases, water temperature decreases and water pressure increases. There changing factors determine the zones and habitats and which organisms can live in each. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 5 EarthquakesThe theory of plate tectonics describes the movement of the plates of the lithosphere relative to each other. This movement creates forces that push and pull on the crust. Crustal rock can absorb and store energy, but only so much. There is a point at which the stress is more than the rock can hold and the rock breaks. When the rock breaks, the stored energy is released and this energy travels through the Earth. This sudden release of energy created when rocks break is called an earthquake Read more...iWorksheets: 6Study Guides: 1Vocabulary Sets: 7 VolcanoesThe intense heat and pressures in the mantle turn solid rock into liquid magma. Magma comes out through the surface of the crust to form volcanoes. Three volcanoes categories are cinder cones, shield volcanoes and stratovolcanoes. The ash and rock that is extruded by explosive volcanoes is called pyroclastic material. This volcanic mudflow is called a lahar. Read more...iWorksheets: 4Study Guides: 1Vocabulary Sets: 4 ClimateOne key factor affecting climate is latitude. Because the Earth is a globe, the sun’s rays hit the equator more directly than they do near the poles. A second factor is that the Earth is tilted at 23.5 degrees on its axis as it rotates around the sun. As it does, the Northern and Southern hemispheres are either pointing toward or away from the sun’s rays. Consequently, lands near the equator have smaller temperature fluctuations throughout the year. The climate is predictably warm and humid. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 6 Bacteria and VirusesBacteria are prokaryotes, meaning that their DNA is in the cytoplasm because they do not have a nucleus. In addition to not having a nucleus, bacteria also do not have many of the other structures that are found in a eukaryotic cell. However, they still meet the criteria for being a living organism. There are three different shapes of bacteria: spiral, rod, and spherical shaped. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 4 Energy and energy resourcesMechanical energy is the energy of a moving object such as an airplane in flight. Thermal energy or heat energy: When a sidewalk warms up from the sun it now has thermal energy. Electrical energy speaks for itself. Whenever electricity is used, its energy is being used. Chemical energy is the energy that gets released when chemical bonds are broken. Electromagnetic energy is energy that travels in waves. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 2 ForcesForce is a pull or a push and its strength is measured in units called newtons and represented by the symbol F. Forces can act in combination and produce what is referred to as net force. Gravity is a type of force that pulls objects towards each other and toward the earth. Newton’s first law is that an object that is at rest will remain at rest and that an object in motion will continue in motion. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 1 MotionWhen motion occurs, there is speed and velocity. Speed is calculated by dividing the distance traveled by the time it took to travel. Velocity has an additional component. Velocity tells you how fast an object is going and where it is going. Therefore, if two objects have the same speed, but are going in different directions, they will have different velocities. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 1 Acids, bases and saltsAn acid is a compound that is defined by its physical and chemical properties. Acids taste sour and react with metals and polyatomic ions called carbonates. A carbonate is a charged cluster of Carbon and Oxygen atoms. In addition, when tested with blue litmus paper, acids turn the paper red. A base or hydroxide, like an acid, is also defined by its properties. Bases taste bitter, are slippery to the touch and turn red litmus paper blue. An example of a base is NaOH or sodium hydroxide. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 1 Mixtures, solutions and compoundsMixtures, unlike compounds, are the physical combination of different substances. Solutions are a type of mixture with at least one solute and solvent. In a solution, finely dissolved particles of a solute are dissolved by the solvent. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 1 Chemistry in our worldChemistry literally affects us twenty four hours a day. At any one moment in our bodies, thousands of chemical reactions are occurring. All of these reactions are controlled by catalyst-like chemicals called enzymes. Most of the chemical digestion of food we eat gets done in our small intestines with enzymes. Outside our bodies, chemicals and their reactions help us in many practical ways. Composites are mixtures of two or more substances, many of which are polymers with different properties, combine to give us better products. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 2 Technology in our worldEngineers use technology to meet human demands and to provide solutions to our problems.

Cell phones using networks of microwave generating cell towers have dramatically changed the way we communicate. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 1 Work and machinesWork is the exertion of force through a distance. The formula for its calculation is: work =force x distance. For an example, if 5 newtons of force were applied for 5 meters, the amount of work done would be 25Nm. Mechanical advantage = output force/input force. For example, if a machine takes the force coming in and multiplies it three times, the mechanical advantage would be 3. Read more...iWorksheets: 5Study Guides: 1 MD.1.0.

The human body has different levels of organization that consist of cells(the smallest), tissues, organs, and organ systems (the largest).

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.

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.
