This week

We are learning about ENERGY!  Students have been learning about light and getting hands on with refraction, reflection and absorption.  This week we'll continue learning about light energy.  We'll also start learning about other types of energy.

VOCABULARY QUIZ: Friday January 20th words students will be expected to know are at the bottom of the post.
Students created either flashcards, foldables, presentations, or Quizlet sets with these words last week.  Below are some of the Quizlet sets and slides created by students.

Social Studies: We are learning about explorers.  Last week students learned about the Silk Road and how that caused European explorers to seek new ways to Asia.  This week we'll be learning about some of the technology they had that made exploration easier as well as the explorers themselves.

Energy — the ability to do work or cause change; can be changed into different forms and can move between objects. 

FORMS OF ENERGY:

·      Chemical Energy — energy that can be released by a chemical reaction

·      Electrical Energy — energy that comes from an electric current

·      Light Energy — energy that we can see directly.  Light energy can be:

o   Absorbed—To take up and store energy without reflecting or transmitting that energy

o   Reflected — the bouncing of heat or light off an object

o   Refracted — the bending of light

·      Mechanical Energy—energy an object has due to its motion or position

·      Nuclear Energy—energy caused by the splitting of atoms

·      Solar Energy — energy that comes from the sun

·      Sound Energy — energy in the form of vibrations that travel through a substance

o   Pitch — a measurement of how high or low a sound is; depends on fast or slow vibration

o   Vibration – the rapid movement of an object back and forth

·      Thermal Energy — energy caused by heat

TYPES OF ENERGY:

·      Kinetic Energy - energy of motion

·      Potential Energy – energy based on position or condition

ELECTRICITY

Atom—the smallest unit of an element; containing the same properties of the element

·      Neutron—a particle within the atom (subatomic) that carries no electrical charge; it has a neutral charge

·      Proton—a particle located in the nucleus of an atom (subatomic) that is positively charged

·      Electron-–a particle within an atom (subatomic) that has a negative charge

Charge—a measure, can be positive or negative; force of electro magnetic interaction.

·      Positive—an electric charge with more protons than electrons; the opposite of a negative charge

·      Negative—an electrical charge in which there is a build up of electrons; the opposite of a positive charge

Static Electricity – electric charges that build up or collect on an object.

Attract—to pull or draw towards

Repel—To force or push away.

Electrical Energy —energy that comes from an electric current

·      Current —the flow of electric charges through a material

·      Circuit —a closed path that an electrical current can flow through

·      Conduct —To transmit heat or electricity through a medium.

o   Conductor—materials that allow heat, electricity, or sound waves to pass through; a substance that allows electrical charges to travel.

o   Insulator—A material used to reduce or prevent the transfer of electricity, heat, or sound.

Electromagnet — a metal object that acts as a magnet when an electric current moves through it; giving it magnetic properties

Generator — a machine that converts mechanical en
