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 the function of each part of a microscope and follow step-by-step instructions on how to focus on a specimen. They also review the proper use and care of a microscope and test their knowledge in two drag-and-drop exercises.

In this animated object, learners read an introduction to protein structure and function.

In this animated object, learners examine the major events that occur at the neuromuscular junction.

In this animated object, learners read a brief description of the roles of the hypothalamus, emotions, and adrenal secretions during the stress response.

In this learning activity you'll review answers to commonly asked questions about the GED/HSED essay and view the official scoring guide.

Be the force to create a safer agricultural community by creating and presenting effective educational presentations. By informing others about biosecurity strategies, you’ll become a biosecurity advocate as you spread the word about its importance!

In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.

Explore what proteins are, their structure, and their functions.

This interactive object is designed to help learners memorize schematic symbols used in pneumatic diagrams. Learners quiz themselves using electronic flashcards.

In this simulation activity, an electrician troubleshoots a defective compressor motor that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

In this animated and interactive object, learners follow steps to perform the process identification procedure for the Ziegler-Nichols Continuous Cycling Tuning Method. A short quiz completes the activity.

Learners review guidelines for the proper use of a dial caliper. Illustrations appear throughout the learning object.

In this simulation activity, an electrician troubleshoots a defective water pump that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

In this animated object, learners examine the eight cranial bones, the fourteen facial bones, and the ribs.

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

In this 3D animated object, learners examine the way in which a three-phase generator produces three sine waves with three armature coils. A quiz completes the activity.

Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.

In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.

In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

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

Learners follow a methodical approach for the dc analysis of series-parallel circuits.

Explore vertical hydroponic growing with Fork Farms and FVTC. We'll introduce you to what vertical hydroponic growing is, why it's important to our economy and the environment, and how you can get started.

This activity is a simulation that allows the learner to practice personal protective equipment tasks.
