Grade 8 Graphic organizer
A grade 8 definition organizer that separates measurable criteria from hard constraints before students propose any fix for nutrient runoff from school athletic fields.
Grade 8 Lab / experiment
A grade 8 lab in which teams run four-day evaporation trials on three cover designs, score each against stated criteria, and build a combined cover from the winners.
Grade 8 Graphic organizer
A grade 8 trade-off matrix organizer for comparing full lead line replacement, corrosion control, and point-of-use filters against five stated criteria.
Grade 8 Graphic organizer
A grade 8 organizer for comparing three tested rain-tank diverters one feature at a time, then combining the best chamber, screen, and reset into a single design.
Grade 8 Worksheet
A grade 8 worksheet using five tested inlet screen designs: students model flow as a linear function of bar spacing, then pick the one design meeting all three criteria.
Grade 8 Lesson plan
A 50-minute grade 8 lesson where students weigh central lime softening, ion exchange, and household rebates against hardness, chloride, cost, and fairness criteria.
Grade 8 Lesson plan
A 55-minute grade 8 lesson where students take four water-sector roles, judge three new-source options from their own criterion, and negotiate one recommendation.
Grade 8 Project
A three-session grade 8 project in which teams design, pilot, and defend a creek sampling network that can detect whether a street-sweeping program is working.
Grade 8 Project
A five-session grade 8 project where teams build tabletop lagoon models, test three air-delivery layouts for dead zones, and recommend a retrofit to a village board.
Grade 8 Project
A four-session grade 8 project in which teams design a staged drought trigger plan from well-level data and defend it to a water board with a one-page notice.
Grade 8 Math problem set
A grade 8 set where students read one nozzle package from a table and one from an equation, compare the unit rates as slopes, and pick the package that fits the pump.
Grade 8 Lab / experiment
A grade 8 lab where teams time sand, silt, and coffee grounds settling through three water depths, then use the speed to size a wastewater grit channel.
Grade 8 Worksheet
A grade 8 worksheet where students build linear cost functions for replacing aging water mains, solve for feet within a budget, and compare two contracts.
Grade 8 Math problem set
A grade 8 set where students write and solve a two-equation system to blend pure reverse-osmosis water with bypass water to hit a target dissolved-solids level.
Grade 8 Lab / experiment
A grade 8 lab where students build a solar still, measure fresh water collected over time, and compute a collection rate and percent recovery from salt water.
Grade 8 Classroom activity
A grade 8 engineering activity where teams design a coagulant recipe on a points budget, test it on muddy water, and iterate to reach the clearest cup.
Grade 8 Worksheet
A grade 8 worksheet where students plot chloride against conductivity for a salted river, draw a line of best fit, and use its slope to predict values.
Grade 8 Quiz & test questions
A grade 8 assessment mixing multiple-choice, computation, and design short-answer items on reducing runoff, using the rational method and scientific notation.
Grade 8 Math problem set
A grade 8 set on a lead service line replacement program where students write two linear equations, solve for the week the crews match, and interpret a no-solution case.
Grade 8 Lesson plan
A grade 8 engineering lesson where students size a floating wetland raft to pull nitrogen from a green campus pond, working within a materials budget.
Grade 8 Quiz & test questions
A 20-point grade 8 quiz on screening a micro-hydro project, mixing constraint identification with forebay volume, pressure, and flow conversion computations.
Grade 8 Classroom activity
A grade 8 station activity where teams pour known volumes through three rigged water meters, then write the linear function that describes each meter's error.
Grade 8 Lesson plan
A 55-minute grade 8 lesson where students set criteria and constraints for capturing air conditioner condensate, then model the storage tank with a linear function.
Grade 8 Worksheet
A grade 8 worksheet turning a streambed survey table into a linear function, comparing two reach slopes, and placing rock riffles where storm flow runs fastest.
