Students review the best practices for using a ruler and answer five basic questions.

In this interactive object, learners identify the risk factors and the precautions to follow when treating a patient with a cardiac condition. They also design a treatment plan for that patient.

Learners study an animation that shows how a battery charge reduces over time and when varying resistance values are placed in a series circuit. Ten review questions complete the activity.

Learners use this interactive and animated object to examine the use of binary numbers in a programmable logic controller. A brief quiz completes the activity.

In this animated and interactive object, learners calculate the area and centroid of a triangle.

The student reads about the parts of a pipe/tubing bender and later identifies them in an interactive review.

In this interactive object, learners change the amount of money received from tax revenue and the amount spent on federal programs as they calculate how fiscal policy affects the gross domestic product (GDP), unemployment, inflation, the annual deficit, the national debt, and interest on the national debt.
