4 Adopt an Element Adopt an element project Page 1 Purpose To research two elements on the periodic table and create a neat, colorful, and creative 8.5 x 11 poster on colored paper that highlights the following information:! Symbol (lettering must be 11 cm high, minimum must be placed in the left hand corner)! Name of element (lettering must be 2 cm high, minimum Must be underneath the symbol.)! Atomic number (lettering must be 2 cm high, minimum Must be placed in the top right hand corner)! Uses (lettering must be 1 cm high, minimum; be creative!)! Fast facts (see grading rubric, for details)! Anything else that will add innovation, creativity, and uniqueness to your poster Materials and resources! You may use a variety of reference sources.! Fast Fact sheets must be neat, written in black ink, and contain all the information requested.! Crayons/markers/colored pencils/paints! Fast facts sheet on which to complete this assignment Created by G. Baker Adapted from and S. Young

What state of matter has the most particle motion? Which state of matter has the least particle motion? Grade and graph your Mad Minute!!!

8 Main Idea Changes in energy can cause matter to change from one state to another. Learning Objectives Compare melting and freezing Compare vaporization and condensation Key Words Temperature Thermal Energy Melting Point Boiling Point Freezing Point Vaporization Boiling Evaporation Condensation Sublimation Deposition! Changes in States of Matter Name: Temperature, Thermal Energy, and Heat A change from one state to another is the result of the change in in an object and the strength of the forces of the particles in the object. Moving Particles and Kinetic Energy Even when an object is not moving, the particles in the object are moving. The particles have. Temperature and Average Kinetic Energy is a measure of the of the particles in a material. Particles in matter move as the temperature. Measuring Temperature One way to measure temperature is to use a liquid. The particles in the liquid move farther apart and cause the liquid to take up more space. Particles of Matter and Potential Energy Particles in a substance have. Potential energy as particles move together. Potential energy as particles move apart. Thermal Energy energy kinetic and potential energy. Objects in the state have particles that move and are compared to objects in the solid state. Gas particles have potential and kinetic energy than particles in a solid. The thermal energy of the gas state is than the solid state for substance. Adding and Removing Thermal Energy a pot of water thermal energy. water in a refrigerator thermal energy. Thermal Energy and Changes of State When energy is in a substance, the of the substance. When only potential energy is increasing, the substance. Changes Between the Solid and Liquid States The difference between water and ice are the of the particles and the thermal energy the particles contain. occurs when a solid changes into a liquid. The of a material is the temperature at which a material changes from solid to liquid. As thermal energy is to a solid, the temperature increases until the melting point is reached. The substance until it has.

9 Energy Changes During Melting Even though thermal energy is still being added, the temperature is not changing as a substance melts. The average kinetic energy of the substance does not change, only the potential energy changes. The attractive forces become weaker as the particles increase speed and move farther apart. Freezing occurs when a changes into a. The is the temperature at which a liquid changes to a solid. Thermal energy is and the potential energy. Vaporization and Boiling is the change from a liquid to a gas. The particles become too and the are too weak to keep the particles close together. Vaporization occurs at the and the liquid. Vaporization that occurs the liquid is called. refers to the temperature that boiling occurs in a substance. Evaporation Vaporization that occurs at the of a liquid is called. Evaporation occurs both at the boiling point and the boiling point. Condensation is the change from a to a. Thermal energy is from a gas. The gas particles and move until the attractive forces hold them together and a. Changes Between Solids and Gases is the change of a to a gas. Thermal energy must be added to a solid. changes from a solid to a gas. The of sublimation is, the change of a to a without. Thermal energy is removed from a gas. Water changes directly to as on leaves. Summary:
