Grade 7 Classroom activity
Grade 7 groups swap crumpled-paper watersheds, place up to three monitoring stations, and use upstream and downstream results to find a hidden leaking site.
Grade 7 Lab / experiment
A grade 7 lab where students measure porosity and soak-in time for gravel, sand, and a mix, then use a boring log to compare a sand-gravel aquifer with clay.
Grade 7 Math problem set
A grade 7 science problem set in which students use meter tests and a dye test to find a home leak, then trace where indoor and outdoor water goes.
Grade 7 Debate kit
A two-session grade 7 science debate comparing dam removal, a fish ladder, and repair at a fictional mill dam, with evidence on fish, sediment, safety, and town use.
Grade 7 Worksheet
A grade 7 science worksheet reading an hourly storm hydrograph from a fictional brook: baseflow, peak, lag time, percent recession, flood stage, and warning time.
Grade 7 Lesson plan
A 50-minute grade 7 science lesson using a fictional bench test of lead released at five pH values to show how corrosion control lowers lead without digging up pipes.
Grade 7 Reading passage
A grade 7 science reading passage on summer layering and fall turnover in a fictional reservoir, with a depth data table and seven comprehension questions.
Grade 7 Lesson plan
A 50-minute grade 7 science lesson where students convert a river's current to miles per hour, find a spill's travel time, and plan sampling before the intake closes.
Grade 7 Writing prompt
A grade 7 science argument prompt on building a truck repair depot inside a fictional town's wellhead protection area, with background, organizer, exemplar, and rubric.
Grade 7 Writing prompt
A grade 7 science writing prompt: explain how a fictional water reclamation plant removes most microplastics, why some still reach the river, and what residents can do.
Grade 7 Lesson plan
A 55-minute grade 7 science lesson comparing storm flow with plant capacity at a fictional town's combined sewer, then sizing the overflow a green plan prevents.
Grade 7 Project
A five-session grade 7 science project on whether parking lot runoff warms a creek, ending in a report and one affordable fix for a fictional public works office.
Grade 7 Debate kit
A two-session grade 7 science debate on a proposed rule requiring planted stream buffers on farms, with two-sided evidence on nutrients, fish, land cost, and fairness.
Grade 7 Lesson plan
A 45-minute grade 7 science lesson on a fictional town's PFAS-tainted well, where students compare test results to the federal limit and study a rule still being changed.
Grade 7 Lab / experiment
A grade 7 science lab where students track how muddy water clears in two jars of different sediment and connect settling speed to a treatment plant's job.
Grade 7 Worksheet
Students use the 0.433 psi per foot constant to turn house elevations in a fictional hill town into water pressures, then judge which homes fall outside safe limits.
Grade 7 Worksheet
A grade 7 science worksheet: students read lead results from 10 homes, find the percent above the action level, and judge if the sample fits the town.
Grade 7 Lesson plan
A 50-minute grade 7 science lesson where students read how a treatment plant works and build a flowchart placing the six stages in the correct order.
Grade 7 Worksheet
Students sort a fictional town's 6,000 service lines by material, find percents, and build a ten-year lead pipe replacement schedule with costs.
Grade 7 Worksheet
A grade 7 science worksheet: students track cloudiness in NTU through a treatment plant, find the percent removed per stage, and compare finished water to the limit.
Grade 7 Math problem set
Ten problems in which students convert acre-feet to gallons, compute days of supply for a fictional town, and test how growth and evaporation shorten it.
Grade 7 Reading passage
A grade 7 science reading passage on bioremediation, tracing how microbes clean sewage and a fictional fuel-leak site, and why PFAS resist the same living cleanup.
Grade 7 Classroom activity
A grade 7 role-play where students move nutrient and oxygen tokens along a lake pathway to model fertilizer runoff, an algae bloom, and an oxygen crash.
Grade 7 Lesson plan
A 50-minute grade 7 lesson where students compute the water footprint of foods, then build an evidence-based argument about how food choices add to water demand.
