Science

• The study of the natural world and its processes.

Safety

• Prevention against hurt, injury, or loss.

Safety Equipment

• Tools used to prevent against injury or loss.

Scientific Method

• A method of research where scientists test a problem and document their results.

Investigation

• A formal examination or research

Prediction

• A statement about something which may occur.

Matter

• Anything that has mass and takes up space.•

Magnetism

• Attracted to a magnet because it contains iron.

Mass

• Amount of matter in an object.

Physical State

• The classification of matter as a solid, liquid, or gas.

Thermal Energy

• Energy that causes a change in temperature between substances.

Inference

• An explanation based on what you already know or what you have seen.

Relative Density

• Objects that are more dense sink in water, less dense objects float in water.

Solubility

• Measurement of the ability for some types of matter to dissolve in a liquid.

Dissolve

• To break down and spread out evenly in a liquid.

Mixture

• A combination of two or more substances where each keeps its own properties and can be easily separated.

Electrical Energy

• Energy produced by the movement of electrons.

Conductor

• Material that allows electric current or heat energy to flow through easily.

Insulator

• Material that slows down or stops electric current or heat from flowing.

Energy

Mechanical Energy

Light Energy

Sound Energy

Alternative Energy Resource

• Energy generated by natural processes that is renewable.

Wind Energy

• Energy from moving air that turns the blades of a turbine to generate electricity.

Solar Energy

• Energy that comes from the Sun.

Bio Fuel / Biomass

• Fuel made from plants, animal wastes, and decomposing plant and animal tissue.

•

Renewable Resource

• Materials from the Earth that can be replaced by nature in a short period of time; for example trees.

Nonrenewable Resource

• Materials from the Earth that cannot be replaced within a reasonable amount of time; for example, coal, oil, and natural gas.

Fossil Fuel

• A flammable material made from the waste and remains of plants and animals in the Earth’s crust that is used to produce heat and power.

Hydroelectricity

• Electricity made from the energy of moving or falling water.

Geothermal

• Energy that comes from the natural heat inside the earth.

Electric Circuit

• The pathway through which electrical current flows.

Electromagnetism

• Magnetism created by an electric current; examples are MRI and Electric motors.

Force

• A push or pull that causes an object to move, stop, or change directions.

Gravity

• A force that pulls objects toward the center of Earth.

Friction

• A force that slows or stops motion when objects rub together.

Inertia

• The property of an object that resists movement by a force.

Kinetic Energy

• Energy in motion

Potential Energy

• Energy that is stored

Illuminate

• To light up

Reflection

• Energy waves bouncing off the surface of an object. (mirrors or echoes return energy back to their source)

Refraction

• Energy waves that bend (change direction and speed) as they pass from one type of object to another type.

Organic Matter

• The waste and remains of plants and animals

Pressure

• The action of force by one object against another (in a geyser, hot water escapes the pressure from under layers of the earth’s crust)

Sedimentary Rock

• Rock made of layers of compressed organic and inorganic sediments.

Oil

• A flammable liquid produced from organic matter (remains of marine organisms) buried under layers of sediments for millions of years.

Natural Gas

• A flammable material without a definite form, produced from organic material (remains of marine organisms) buried under layers of sediments found near oil deposits.

Weathering

• The breakdown of rock into smaller particles (sediments) from the effects of wind, water, and ice.

Erosion

• The movement of weathered material on the Earth’s surface by wind, water, or ice.

Deposition

• The build up of land by depositing sediment and soil in a new location.

Landform

• Features on the surface of the earth such as mountains, hill, dunes, oceans, and rivers.

Delta

• A triangle-shaped (deposit) landform at the mouth of a river as it empties into another body of water.

Canyon

• A deep gorge in the surface of the Earth formed by the erosion of moving water and sand.

Sand Dune

• Hills formed by the wind blowing sand

Volcano:

• Created from the mixture of molten lave, ash, and gases from the middle of the Earth that erupts through a crack in the Earth’s surface.

Earthquake

• A sudden release of energy under the Earth’s surface that makes the ground shake or crack.
