The learner listens to and sees Chinese vocabulary words used to describe hobbies, sports, and other pastimes.

In this interactive object, learners examine the structural-functional, social-conflict, and symbolic interaction analyses of sports. A mind map and quiz questions are included.

In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.

Explore what passive transport diffusion is and how it moves water through a membrane.

Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.

In this animated object, learners examine processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.

In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.

In this animated object, learners examine water molecules moving through a semipermeable membrane.
