Grade 7 Lab / experiment
A grade 7 lab where teams test three baffle layouts in a model settling basin, then build a fourth that combines features from their best layout and a partner team's.
Grade 7 Graphic organizer
A grade 7 organizer for reading three media-bed test results, naming the feature worth keeping from each, and stacking those features into one combined filter design.
Grade 7 Project
A five-session grade 7 project where teams screen four nitrate-cutting designs against land, budget, and drainage limits, then pitch one to a fictional drainage board.
Grade 7 Lesson plan
A 50-minute grade 7 lesson matching laundry greywater supply to courtyard irrigation demand, then screening three layouts against a coverage target and a budget.
Grade 7 Graphic organizer
A grade 7 organizer pairing a pass-or-fail constraint screen with a weighted scoring matrix for three PFAS treatment options at a fictional water district.
Grade 7 Graphic organizer
A grade 7 organizer that turns vague meeting comments about a failing water main into measurable requirements, sorted into criteria and constraints with named impacts.
Grade 7 Project
A five-session grade 7 build-and-test project where teams design bank shade structures on a model reach, run three timed heat trials, and combine the best features.
Grade 7 Worksheet
A grade 7 worksheet that screens three pump station upgrades against capacity, lot size, downtime, and cost limits, then compares their weekly energy use.
Grade 7 Project
A four-session grade 7 project where teams order and justify the treatment steps ahead of a fictional brackish-well membrane plant, then defend the train to the board.
Grade 7 Lesson plan
A 55-minute grade 7 lesson where students size storm runoff from a fictional road-salt pad, then pick among a full roof, a partial roof, and a catch basin.
Grade 7 Lab / experiment
Students build three filter designs, time how fast each runs, rate how clear the water is, and find the trade-off between speed and clarity.
Grade 7 Lesson plan
A grade 7 lesson where students build a proportional sampling plan for a fictional school's drinking taps, infer how many exceed the action level, and size a retrofit.
Grade 7 Classroom activity
A grade 7 station rotation where teams make one decision at each of four water-utility desks, then compare the constraints that pushed each role toward a choice.
Grade 7 Worksheet
A grade 7 worksheet on a fictional quarry seep where students size a limestone treatment cell, test it against a retention-time rule, and deepen it for spring flows.
Grade 7 Math problem set
Students plan a fictional town's lead service line replacement, finding yearly pace, program cost, grant share, and how a test result compares to the action level.
Grade 7 Quiz & test questions
A grade 7 engineering unit test on a fictional stormwater retrofit, mixing multiple-choice, short-answer, and computation items on runoff and percent reduction.
Grade 7 Math problem set
A grade 7 problem set on a fictional sludge digester where students work percent reduction, biogas volume, and the share of a plant's daily electricity it covers.
Grade 7 Lesson plan
Students design a managed aquifer recharge basin for a fictional town, choosing a site and shape that refill a falling aquifer within real constraints.
Grade 7 Worksheet
Students design a fictional town's carbon filter for PFAS, using percent removal to check each well against the 4.0 ppt limit and sizing the daily flow.
Grade 7 Math problem set
A grade 7 problem set on a fictional dam where students size a fish ladder's pool steps, convert between drawing inches and real feet, and redraw at a second scale.
Grade 7 Lesson plan
Students design a water-quality monitoring plan for a fictional creek, choosing sampling sites and tests to detect three pollution sources within real limits.
Grade 7 Lab / experiment
A grade 7 lab where students build three mesh panels, spray them under identical conditions, and use the collected volumes to design a better fog-catching panel.
Grade 7 Math problem set
A grade 7 set on a fictional well field where students find a drawdown rate as a constant of proportionality and solve an inequality for safe pump hours.
Grade 7 Math problem set
Students compare a fictional farm's sprinkler and drip systems, using proportional reasoning and percent to size the daily and seasonal water they save.
