Science@Work II showcases Ohio people, applying in everyday life, the Physical Science concepts that instructors are teaching to their students. The target populations for Science@Work II are grade levels 8, 9, and 10. Each module title contains the entire uncut video, a content segmentation aligned to the current Ohio Educational Content Standards, a closed-captioned file, and a descriptive video file. It is WBGU-TV's goal to expand the reach of these programs to students with different learning styles and students with disabilities.

Tracing Energy Transformations
In this episode we will trace the transformations of energy within a system and recognize that energy is conserved. The transformation of chemical energy to electrical energy to mechanical energy is traced through a car. Thermal energy is also released.
Illustrating Exothermic and Endothermic Reactions
In this program we will investigate exothermic reaction, producing heat energy as the reaction takes place, and endothermic reaction, heat energy being required for the reaction to occur. Example: making of ice cream.
Explaining Thermal Energy
In this episode, we will explain how thermal energy exists in the random motion and vibrations of atoms and molecules. All objects, even solids have molecular motion. The higher the temperature the greater the average atomic or molecular motion. In changes of state the temperature remains constant.
Demonstrating Thermal Energy Transfer
This episode demonstrates three ways thermal energy can be transferred: conduction -- collision of particles, convection -- currents created by differences in temperature and density, and radiation -- electromagnetic waves.
Showing Wave Properties
This program explores the properties of waves which is determined by the medium through which the waves travel. Electromagnetic waves can travel through a vacuum as well as matter.
Describing Wave Behavior
This episode will investigate wave behaviors, including interference, refraction, reflection and diffraction.
Demonstrating Properties of Electromagnetic Radiation
This program explores electromagnetic radiation which does not require a medium through which to travel. Visible light acts as a wave and is only a small portion of the electromagnetic spectrum.
Describing Radioactive Substances
This episode reviews the structure of atoms, compares radioactive and non-radioactive substances, and discusses nuclear decay.
Summarizing Energy and Matter Transformations in Nuclear Reactions
This program summarizes how nuclear reactions convert a small amount of matter into a large amount of energy. Fission involves the splitting of a large nucleus into smaller nuclei. Fusion is the joining of two small nuclei into a larger nucleus.
