Energy
Energy is the ability to do work. It is what makes things happen and allows objects to move or change. There are many forms of energy, including kinetic, potential, thermal, chemical, electrical, and sound energy.
Forms of Energy
- Kinetic Energy: energy of motion
- Potential Energy: stored energy
- Thermal Energy: heat energy
- Chemical Energy: energy stored in the bonds of atoms and molecules
- Electrical Energy: energy from electric charges
- Sound Energy: energy produced by vibrations
Energy Transfer and Transformation
Energy can be transferred from one object to another or transformed from one form to another. For example, when a ball is thrown into the air, the potential energy is transformed into kinetic energy as it moves.
Sources of Energy
Energy Conservation
It's important to conserve energy to reduce our impact on the environment. This can be done through energy-efficient practices and using renewable sources of energy.

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
