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.
Passive Transport: Filtration and Facilitated Diffusion
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.
Learners read and listen to phrases in Mandarin Chinese that would be part of directions to common locations. Additional vocabulary words related to forms of transportation are also presented.
