To make a household water fixtures use setup (see Figure 1, which the teacher constructs) for one group:

• shoebox (or any similarly-shaped box to support six funnels)
• (optional) 8 Popsicle sticks (to make shoebox more sturdy)
• (optional) duct tape (to make shoebox more sturdy)
• 6 funnels
• plastic tubing that fits snugly on the ends of the funnels
• 2 large measuring cups marked in ml
• marker
• masking tape
• scissors
• box cutter

Each group also needs:

• 1 medium-sized cup or beaker to hold and pour ≤ 100 ml water
• graduated cylinder or something to measure ≤ 100 ml
• colored pencils, markers or crayons (for coloring bar graphs)
• Shades of Gray(water) Worksheet, one per student

To share with the entire class:

• pitcher of water
• 1 container of liquid food coloring
• sponge/paper towels, for any clean-up needed

Note: Plan on each initial household water fixtures use setup costing ~$3 per group, and then about 10¢ each time you run the activity again because you are reusing the shoebox setup.
