Fix It or Let It Drip? A Grade 4 Water Repair Decision Activity

A grade 4 station-rotation activity where small groups weigh the benefits and costs of fixing four household water leaks for a family with a limited repair budget.

Objectives

  1. Students will compare the benefit and cost of fixing four different household water leaks.
  2. Students will use a real fact about how much household leaks waste in a year to support a decision.
  3. Students will explain how a family with limited money might set repair priorities.

Vocabulary

Water conservation
Using less water and using it wisely so there is enough for people and nature now and in the future. Small actions matter, since a faucet dripping once per second wastes roughly 3,000 gallons per year.

Also: leak, benefit, cost

Teacher overview

This is a small-group station-rotation activity for a class of about 20 to 24 students, working in four groups of five or six. Each of four stations describes one leaking fixture in the home of a fictional family, the Alvarez family, who have only a limited amount of money to spend on repairs this month. Groups read each leak's description, weigh its benefit (water and money saved) against its cost (repair price and effort), and decide whether the family should fix it right away or wait, turning an abstract idea like "costs and benefits" into four concrete household decisions.

Activity Directions

  1. Before class, print or write out four station signs, one for each leak: the Kitchen Faucet, the Running Toilet, the Garden Hose, and the Pipe Under the Sink. Post them around the room, spaced far enough apart for a group to gather at each one.

  2. Explain the setup to the whole class: suppose the fictional Alvarez family has noticed four leaks around their house, but this month they only have enough money to fix two of them. Every dollar amount in this activity describes the Alvarez family's imagined household budget, not a real utility's prices.

  3. Read aloud the shared fact that grounds the whole activity: household leaks waste an average of about 180 gallons of water per week, or nearly 9,400 gallons in a year, according to the EPA's WaterSense program. Tell students that some leaks waste far more than this average and some waste less, which is part of what each station card will describe.

  4. Divide the class into four groups and assign each group a starting station. Give each group a decision card to record their answers.

  5. At each station, groups read the leak's card (see Student Handout) and answer two questions on their decision card: what is the main benefit of fixing this leak now, and what is the main cost of fixing it now? Groups then mark the card "Fix it now" or "Wait" and write one sentence explaining their choice.

  6. After 6 minutes, call time and rotate groups to the next station clockwise. Repeat until every group has visited all four stations, about 24 minutes total.

  7. Gather the whole class. Ask each group to share which single leak they would fix first if the Alvarez family could only afford one repair this month, and why. Record each group's top choice on chart paper to see whether the class tends to agree.

  8. Close with the three debrief questions in the Answer Key, ending with: "The Alvarez family cannot fix every leak at once. What should they think about when deciding which leak to fix first?" End the activity once every group has shared and the debrief questions have been discussed.

Student Handout

Station 1: The Kitchen Faucet. This faucet drips almost every second, day and night. Suppose a new washer to fix it costs about $5 and a family member can install it in ten minutes, no plumber needed.

Station 2: The Running Toilet. This toilet keeps running softly after every flush, wasting water the whole time. Suppose the part needed to fix it costs about $10, and it takes a family member about thirty minutes to install.

Station 3: The Garden Hose. This outdoor hose leaks at the connector, but only during the warmer months when it is in use. Suppose a new rubber washer for the connector costs about $2 and takes two minutes to install.

Station 4: The Pipe Under the Sink. This is a slow, hidden leak inside the cabinet under the kitchen sink. It is harder to reach, so suppose fixing it requires calling a plumber, at a cost of about $75 for the visit and repair.

Answer Key

  1. Debrief question: "Which station likely offers the best benefit for the lowest cost?"
    Answer: Most groups should identify the Kitchen Faucet or the Running Toilet, since both have a low repair cost and a simple fix, and both waste water all the time until they are fixed. The Garden Hose is the cheapest fix, but it leaks only while the hose is in use, so fixing it saves less water.

  2. Debrief question: "Why might the Pipe Under the Sink be harder to decide about than the other three stations?"
    Answer: It costs the most to fix and requires calling a plumber rather than a quick family repair, yet a hidden leak can waste water for a long time before anyone notices it, so its true cost of waiting may be larger than it first appears.

  3. Debrief question: "The Alvarez family cannot fix every leak at once. What should they think about when deciding which leak to fix first?"
    Answer: Answers will vary but strong responses weigh both the repair cost and the ongoing cost of waiting, such as how much water and money keep being wasted the longer a leak continues, and whether a leak is easy for the family to fix themselves or requires paying someone else.

Differentiation

Support (below grade level)

Provide a simple two-column recording sheet at each station with "Benefit" and "Cost" already labeled, and read each station card aloud to the group before they discuss, rather than having students read it independently.

Extension (above grade level)

Ask advanced groups to rank all four leaks from "fix first" to "fix last" for the whole family, not just choose one, and to write a two-sentence justification for their full ranking that mentions both repair cost and the leak's likely water waste.

ELL supports

Pair the station names with simple icons (a dripping faucet, a toilet, a hose, a pipe under a cabinet) on each sign, and allow groups to record their "Fix it now" or "Wait" decision with a circled word and a single supporting phrase rather than a full sentence.

Extensions

Ask students to look for real leaks at home with a family member, such as a dripping faucet or a toilet that keeps running after a flush, and to report back on one leak they found and whether their family decided to fix it right away or wait, connecting the classroom decision-making to a real household choice.
