In this learning activity you'll study the structure of the cell membrane and construct it using the correct molecules.

In this video you'll study the structure of the cell membrane and construct it using the correct molecules.

In this animated activity, learners examine nanotechnology applications that are based on cell membrane structure and function.

In this interactive object, learners read the definitions of the parts of a cell and assemble a basic eukaryotic cell in a drag and drop exercise. A matching quiz involving cell terms and their definitions completes the activity.

In this learning activity we’ll learn how the web works by using a Request and Response algorithm.

This screencast will help the student identify normal blood cells and their functions. This will include the identification of red blood cells, five types of white blood cells, and platelets.

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

Students read how to lock a cell that is being referenced in a formula so that it does not automatically show an increment when the formula is copied.

In this learning activity you'll explore how computers connected on a network use Ethernet technology.

In this interactive object, learners examine how work is performed in foot-pounds by a hydraulic system that uses a pump and cylinder. A brief quiz completes the activity.

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

Learners examine how CEC, base saturation, and soil pH work with each other to define plant nutrient availability.

Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

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

Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units.

Learners examine the different stages of maturation for red blood cells, white blood cells, and platelets. A quiz completes the activity.

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.

Learners examine how metal detectors function. This object includes animation and sound.

In this animated object, learners are introduced to the structure and function of animal cell organelles.

In this animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.
