The learner will understand how to measure a problem over time by using a common run chart to visualize the gap between past performance and future goals.

An Algebraic Word Problem Involving Motion: Case 2

In this animated object, learners use an algebraic formula to solve the following problem: An airplane travels a certain distance with the wind in the same amount of time that it takes to travel a shorter distance against the wind. Given a constant wind speed, what is the speed of the plane without a wind?

Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

Learners read about how universities, government agencies, energy companies, and nanotech firms are working together to use nanotechnology to help produce clean water for consumption.
