This the effect of the apparent flow of electrons through a conductor. People also refer to this when they talk about using electrical energy to power their homes, cars, and other things.

These are any type of object through which an electric current can flow. Metal wire is the most common. These are used in electric circuits. are any type of object through

These have a backbone, or spine, that runs the length of their body, and they are sorted into five groups: fish, amphibian, reptile, bird, and mammal. Bass, tree frogs, alligators, brown thrashers, and deer are examples this classification group.

These are the many different parts that make up a cell. (Nucleus, Cell Membrane, Cytoplasm Chloroplasts, and Cell Wall)

These are single-celled microorganisms that can live in almost every environment and grow and

reproduce on their own. Many types of these are beneficial, like the ones that make cheese or break down chemicals and waste. Many others are harmful, like the ones that cause illness or spoil food.

Animals without backbones are part of this classification group. They include insects, spiders, and crabs.

These use seeds to reproduce. Some plants make their seeds in flowers, while other plants do not. Pine trees are classified as plants that make seeds without using flowers. Apple trees and roses are examples of plants that make seeds by using flowers.

Behaviors like where to find food or how to raise offspring are taught to an organism, or discovered through interactions with the environment. Being able to tie shoelaces is an example of is type of behavior.

These are developed after the organism is born and are not passed to offspring by parents. Having a scar or being a fast runner are examples.

Plants that do not reproduce by seeds. Ferns are an example of this type of plant.

These objects are used to magnify objects. Some objects are too small to be seen without magnification.

These can be controlled by building dams to hold back floodwaters and to let the excess water move downstream more slowly or by building levees (earthen walls along riverbanks) to prevent rivers from going outside their banks onto surrounding land. Cities can also modify their storm drain systems or direct the drainage flows to retention ponds to slow the runoff of rainwater into streams and rivers to reduce the risk of this process.

Scientists have a tool they can use to detect,

measure, and record seismic waves. As an earthquake or volcanic eruption starts, a this detects the increase in the strength and frequency of seismic waves. Earthquakes can trigger volcanic activity and tsunamis. Scientists can analyze the data to determine the likelihood of a tsunami forming.

This is the molten rock below Earth’s crust. When it breaks the crust, it is called lava.

These can be found where faults are located under the ocean. Valleys and canyons, are small versions of this and are also created by erosion.

These are sheets of very old ice that are the size of states and that move along Earth’s surface, also create valleys as they slowly grind along the surface.

These are the different forms in which matter can be found. (Solid, Liquid, and Gas)

This happens when matter breaks down into two or more substances or when more than one substance is combined to form a new substance. Hydrogen peroxide forming bubbles on its own is an example of matter breaking down into two substances. Vinegar and baking soda turning into bubbling foam is an example of two substances combining to create other substances.

This is created when an electric current flows through a wire. In general, the wire in one of these is wrapped around a core made of a magnetic metal, such as iron or steel. A magnetic field is created around the wire, turning the core into a temporary magnet. When the electric current is turned off, the magnetic field quickly fades. You can make this using a circuit with a battery, switch, and wire wrapped around a nail.

These are any properties that can be measured only by chemically changing an object. Paper starts to burn at around 450 degrees. At this temperature, the paper combines with oxygen in the air and new substances are formed.

These are the smallest unit of life and make up all living things. They perform basic life functions, such as making energy, growing, repairing, and getting rid of waste. These can look different and perform different roles in an organism.

This is a destructive process where Earth materials such as rocks and soil are broken down into smaller parts. It can also break down roads, buildings, and other materials humans make.

These have no definite shape and take the shape of their container.

This is a constructive process whereby soil and rock that are eroded from one location are deposited as sediment in another location. As the sediment from a river is deposited at the mouth of a river over time, new land is created, which is called a delta. An example is the Mississippi delta.

The surface of Earth, including under the ocean, is made up of these.These form sections of the surface of Earth, and some plates move toward or away from each other. Plates can also slide past each other.

These are vibrations that move through Earth.

This is thrown out by volcanoes.

These are formed when tectonic plates collide and both push up. This creates hills and mountains. These and individual mountains can also be formed in areas where magma, molten rock from Earth’s core, pushes up between or through tectonic plates. Stone Mountain may be one of these magma-created mountains.

The area where two or more tectonic plates meet and show movement.

This is the force of attraction between two electrically charged objects or a charged object and a neutral object. When you use a balloon to pick up pieces of paper, the force between the balloon and pieces of paper is great enough to pick up the pieces of paper. Objects cling to each other when there is enough electricity.

This is the flow of an electric charge through a conductor. When this move through a conductor, they create heat and magnetic fields. Lightning, static electricity, and the movement of electricity in power lines are examples.

This is the buildup of an electrical charge in or on the surface of an object. When two objects, like a balloon and a piece of cloth, are rubbed together, some of the electrons from one object stick to the other object. This causes the buildup of a charge on one of the objects. When a second object is brought near the first object, the buildup of the electrical charge can jump across to that second object. When the electrical charge jumps from one object to another, it is said to have discharged. This is the spark you see.

Interactions like babies crying for food or being quiet in the nest when parents are away, are this type of behaviors because the organism knows how to behave without being taught.

These are objects which an electric current cannot flow. Glass and rubber are very common examples of these materials. These are used to protect people from electric currents.

These are any properties that are measurable and can be seen. These properties can be determined without changing the chemical properties of an object. Color, hardness, area, length, strength, and temperature are examples.

These are living things that are too small to be seen without magnification. Some are beneficial to people and the environment. Others can be harmful and cause disease.

These are even smaller than bacteria and cannot reproduce or grow unless they infect another organism. These use the organism to stay alive and make copies of itself, eventually making the host organism sick.

Scientists organize them into groups based on characteristics they share, so that they can study ways those things are similar or different. It can be used to identify and study species.

These are organisms that make their own food. They can be classified by the way in which they transport materials within the organism. They can also be classified by the way in which they reproduce.

These are the physical characteristics that are used to describe an organism. Some are unique to individual organisms, and some are common because they are shared by many individuals. These can be divided into two main types: inherited and acquired.

These are passed from parent(s) to offspring. Fur color and beak shape are examples that are passed down from parents to offspring.

To make one of these you need at least a power source and a path for the electric current to flow through. You can add objects, such as light bulbs, along the path. You can also add a switch to start and stop the flow of an electric current through.

This is produced when magnetic fields are generated. This is a property of certain types of materials that allows them to attract or repel other objects that have this property. It is generated by the presence of magnetic fields or by the presence of an electric current.

This happens when matter has a change in its physical properties but not its chemical properties. For example, salt can be dissolved in water, but, if the water evaporates, the salt is still there.

This is done to reduce the effects of erosion on beaches can be accomplished by dredging sand from the ocean floor and depositing it back on the beach.

This happens when tectonic plates suddenly slide around. The plates shake, and the energy from that creates waves that echo through Earth.

These have a definite shape and volume. Their shape and volume cannot be easily changed.

This is the movement of materials from one place to another by natural methods. It can be a destructive process, such as when a landslide moves material from the top of a mountain.

This is something that contains two or more substances that are not combined chemically. Salted popcorn is an example of this. Something is an example of this if you can physically separate the mixture into the substances that made up the mixture. You can tell that salt water is an example because you can evaporate the water and all that will be left is salt.

This is anything that has mass and is in one of the states of matter.

As the sediment from a river is deposited at the mouth of a river over time, new land is created.

This is a break in Earth’s crust that lets magma come out from the mantle and onto Earth’s surface. They can be found in the deep ocean and on Earth’s surface. They are a constructive process. They show up on Earth’s surface where the magma can push through weakness in the crust.

This is the state of matter that has a definite volume but no fixed shape.

When an earthquake happens under water. This happens when the energy released by an earthquake is transferred to the column of water above it and creates waves that travel away from the area. These happen where the ocean meets the shore. The water starts to rise as the waves from the earthquake push the water up. These waves are longer than regular water waves. As these waves hit the shore, it carries much more water and creates a lot of damage

The green structure is found only in plant cells and uses energy from the sun to make food.

This is the brain of the cell. It controls all the cells activities.

This is the outer layer of an animal cell. It controls what enters and exits the cell.

This is the outer layer of a plant cell. It supports the cells and helps it keep its shape.

This is the jelly-like substance found in both plant and animal cells that holds and protects the cell's organelles.
