Life Science - Tracking Matter: Movement Of Matter, Cassandra Armstrong

Model NGSS Lessons: 4th - 5th Grade

Energy exists in many forms and is constantly being transferred between forms. All energy types can be sorted into two main categories: potential and kinetic. Potential energy is stored energy. Chemical energy, nuclear energy, stored mechanical energy, and gravitational energy are all examples of potential energy. Kinetic energy is the energy of motion. Radiant (light) energy, thermal energy, sound energy, and electrical energy are all examples of kinetic energy. Energy cannot be created or destroyed, only transferred between the types of energy. Most energy we use on Earth stems from the nuclear energy from within the sun.

Life Science - Structure And Function: Internal And External, Patrick Young, Nicole Ross

Model NGSS Lessons: 4th - 5th Grade

Plants and animals evolve to survive and reproduce in their environments. Both their internal and external structures will be well suited to support survival, growth, behavior and reproduction.

All animals have a mouth. Its function is to take in food, without which it could not survive to reproduce. The type of mouth, however, will vary between animals, depending on what they have evolved to eat. Internal organs of the digestive system will likewise vary depending on an animal’s diet. All parts of the system for eating and digesting food must work together.

Plants also have internal systems for processing food …
