The risk of contracting an infection in the hospital is low, but it does happen. Learn what risk factors have the highest correlation with hospital-acquired infections in the final lesson of a three-part series. Using the open source R...

Turn expressions into equations with a statement of equality. Individuals view the step-by-step process of writing two expressions and then setting them equal to find a value that makes them equal. The equation has variables on both...

Can you determine the exact volume of a bottle based on the relative volume of other bottles? A series of four videos shows someone pouring fluid into bottles. Scholars must set up a system of equations to determine how much each bottle...

Math is like another language with a vocabulary all its own. Translating verbal statements to mathematic symbols is a challenging task for learners. The video instruction provides several examples viewers watch—and rewatch—to improve...

Express yourself! Using a table method, the lesson presentation explains how to convert a verbal expression into an algebraic expression. The examples include problems with a variety of operations.

Variable expressions can take many shapes and forms. Learners review the different components of many different variable expressions in a straightforward video lesson. After introducing vocabulary, the instructor uses context to write...

Young scientists learn the importance of experimental design and the key elements of an experiment. Through observing videos and designing their own experiments, scholars apply each lesson plan they learn.

Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

Keep everything under control. The lesson, the 16th segment in a 22-part unit, provides a more detailed look at the parts of a plane, specifically the control surfaces. Pupils learn about the construction of the wings and the tails and...

Build a solid understanding of equivalence before introducing equations. An interactive lesson helps learners explore the concept of equivalent expressions. They use an applet to write and make conclusions about expressions.

What factors affect the time it takes a ball to roll down a ramp? Learners build an experimental design by considering these variables. They collect data in two-way frequency tables and analyze them for patterns.

Recycle, reuse, and rearrange! Young scholars learn to rearrange formulas to highlight a variable of interest. They then use their new formulas to make calculations.

Determine if your classes understand the meaning of independent and dependent variables. An application question asks scholars to define a set of variables as well as determine appropriate units for each. They must also consider the best...

The process is literally the same for solving an equation. Pupils gain practice in manipulating formulas and equations to solve for a variable of interest. The instructional activity connects solving literal equations to solving an...
