Strand 8.2: ENERGY IS STORED AND TRANSFERRED IN PHYSICAL SYSTEMS

Objects can store and transfer energy within systems. Energy can be transferred between objects, which involves changes in the object's energy. There is a direct relationship between an object's energy, mass, and velocity. Energy can travel in waves and may be harnessed to transmit information.

Standard 8.2.6

Obtain and evaluate information to communicate the claim that the structure of digital signals are a more reliable way to store or transmit information than analog signals. Emphasize the basic understanding that waves can be used for communication purposes. Examples could include using vinyl record vs. digital song files, film cameras vs. digital cameras, or alcohol thermometers vs. digital thermometers. (PS4.C)

• SEEd Storyline 8.2.6
  Storyline Big Ideas: Digital signals are a more reliable way to store or transmit information than analog signals. Why can a cd (or hard drive?) hold so many more songs than a vinyl record even though a record is larger?
