Grade 7 Quiz & test questions
A 32-point grade 7 test where students size a fictional irrigation pond, compute seepage saved by two liners, and compare their yearly costs before recommending one.
Grade 7 Math problem set
Students size a fictional constructed treatment wetland, compute nutrient removal percentages, and check the design against a budget and a water-quality goal.
Grade 7 Lesson plan
A grade 7 lesson where students use a map scale to find a drainage area, size the design flow for a fictional culvert, and separate its criteria from its constraints.
Grade 7 Classroom activity
Student teams role-play a fictional water board, scoring three competing supply designs on a shared decision matrix and defending one recommendation.
Grade 7 Worksheet
A grade 7 worksheet where students stack a fire reserve, a day of demand, and an operating reserve, then test a fictional village's proposed tank against the total.
Grade 7 Worksheet
Students size a fictional town's booster pump, turning water height into pressure and checking each neighborhood against a service pressure range.
Grade 7 Lesson plan
A 50-minute grade 7 lesson where students separate design criteria from constraints for a school rain garden and calculate the runoff volume it must capture.
Grade 7 Classroom activity
Grade 7 teams build a model silt fence, test it against a no-fence control with a measured water pour, then redesign and retest to reduce sediment reaching a model creek.
Grade 7 Worksheet
A grade 7 worksheet where students calculate cost per year of service for two pipe materials and use the results to recommend a water main replacement design.
Grade 7 Lesson plan
A 50-minute grade 7 lesson where student teams score three prototype filter designs on a weighted rubric and use the totals to choose the strongest design.
Grade 7 Worksheet
A grade 7 worksheet where students use a stated recovery rate to size a reverse-osmosis pilot's clean water output and reject volume against a service constraint.
Grade 7 Quiz & test questions
A 22-point grade 7 unit test with multiple-choice, short-answer, and computation items on design criteria, removal efficiency, and backwash waste.
Grade 7 Math problem set
Seven problems where students test a rain barrel array for proportionality, write its equation, and use percent to see how much of a storm it can capture.
Grade 7 Math problem set
Eight problems where students convert a rainwater cistern blueprint's scale measurements to actual feet, find its volume in gallons, and redraw it at a new scale.
Grade 7 Lesson plan
A 55-minute grade 7 lesson where teams test a model berm spillway across three redesigns, recording freeboard changes to find the most flood-resistant version.
Grade 7 Worksheet
A grade 7 engineering worksheet where students size a fictional stormwater pump station, converting flow units and applying the continuity equation to a constraint.
