A grade 8 science problem set where students model a fictional town's reverse-osmosis and conventional plant energy use as linear functions and compare the two slopes.
Grade 8 Worksheet
A grade 8 science worksheet on lead in drinking water: students weigh corrosion control, compare tap results to the shifting action level, and use scientific notation.
Grade 8 Worksheet
A grade 8 science worksheet where students convert head to pressure on a fictional hillside system and solve linear equations for an unknown tank elevation.
Grade 8 Worksheet
A grade 8 science worksheet where students build a linear function for roof runoff, predict the most water caught per storm, and connect the model to stormwater control.
Grade 8 Reading passage
A grade 8 science reading passage about a summer algae bloom that made a fictional town's tap water taste earthy, and how the plant treated the symptom and the cause.
Grade 8 Worksheet
A grade 8 science worksheet on PFAS removal at a fictional well, using scientific notation and removal efficiency to compare readings against the 4.0 ppt limit.

A 50-minute grade 8 lesson where students model a fictional town's cast-iron water main replacement with linear functions for miles remaining and cumulative cost.
Grade 8 Lesson plan
A 50-minute grade 8 science lesson where students run a fictional water plant's numbers: converting MGD to gpm, sizing a pump for peak demand, and setting criteria.
Grade 8 Worksheet
A grade 8 science worksheet where students read a fictional lake's dissolved-oxygen depth profile, find the low-oxygen zone, and trace a nutrient-driven fish kill.
Grade 8 Worksheet
Grade 8 students at the fictional Sable River Dam write reservoir capacity, downstream releases, and hydropower figures in scientific notation and compare their sizes.
Grade 8 Lesson plan
A 50-minute grade 8 science lesson where students calculate runoff from a fictional school's paved lot and model how a rain garden reduces stormwater.
Grade 8 Lab / experiment
A grade 8 science lab where students evaporate salt water, measure the salt left behind, and scatter-plot class data to model the water cycle and distillation.
Grade 8 Lesson plan
A 45-minute grade 8 lesson where students find chlorine demand and filter loading rate at a fictional plant and read loading rate as a proportional relationship.
Grade 8 Classroom activity
A grade 8 science activity where groups build a sand aquifer model, release a dye contaminant, and map how the plume spreads toward a well.
Grade 8 Worksheet
A grade 8 science worksheet where a fictional family audits its water use: per-person demand, two showerhead flow rates as slopes, and toilet and leak losses.
Grade 8 Math problem set
A grade 8 science problem set on a fictional gorge dam: the constant of proportionality between flow and power, two turbines compared, and a Hoover Dam scale check.
Grade 8 Worksheet
A grade 8 science worksheet on a fictional plant's anaerobic digester: volatile solids destroyed, biogas produced, and yearly electricity in scientific notation.
Grade 8 Math problem set
Grade 8 students model a fictional well's drawdown and pumping level as linear functions of pumping rate, then check finite aquifer storage with scientific notation.
Grade 8 Worksheet
A grade 8 science worksheet using Q = A x V on a fictional district's hydrant test to find velocity, travel time, and whether pressure stays above the required minimum.
Grade 8 Lab / experiment
A grade 8 lab where students track a settling column's clarity over 40 minutes, graph clarity against time, and connect the trend to sedimentation-basin design.
Grade 8 Lab / experiment
A grade 8 science lab where students run a jar test, dosing muddy water with alum, rate each jar's clarity, and find the coagulant dose that clears it best.
Grade 8 Lab / experiment
A grade 8 science lab where students time how fast water passes through sand, loam, and clay, calculate infiltration rates, and connect them to recharge and runoff.
Grade 8 Worksheet
A grade 8 science worksheet in which students read five sequential tap samples from a fictional home to locate the lead source and compare results to the action level.
Grade 8 Worksheet
A grade 8 science worksheet where students model how a reverse osmosis membrane separates water from dissolved salt and calculate salt rejection.
