How well can your class concentrate on solutions? Scholars use colorimeter absorption to explore a starch concentration calibration curve. They add iodine to different starch solutions to see how the concentration of the solution changes.

This assessment pair goes way beyond simple graphing, factoring and solving polynomial equations, really forcing learners to investigate the math ideas behind the calculations. Short and to-the-point questions build on one another,...

Create tables of solutions of linear equations. A lesson has pupils determine solutions for two-variable equations using tables. The class members graph the points on a coordinate graph. 

Inequalities: when one solution just doesn't suffice. Individuals learn to write inequalities in real-world contexts and graph solution sets on the number line. All inequalities in the lesson are of the form x < c or x < c.

Need a less abstract approach to introducing extraneous solutions? This is it! Young mathematicians explore properties used to solve equations and determine which operations maintain the same solutions. They...

To conclude a mini unit on the dissolving of M&Ms® candy coating, this lesson investigates whether or not the concentration of sugar in the solvent affects the dissolving rate. Consider having older science learners write their own...

You know global warming is real when your squirrel feeder is full of popped corn instead of kernels! Activity two in a series of five allows learners to explore climate change through the eyes of another. After briefly analyzing their...

A single page provides you with lecture notes for your lesson on hydrolysis. Introduce your chemistry class to Bronsted-Lowry theory by explaining the hydrolysis of acidic cations and basic anions. Show them how the resulting pH can be...
