Each group needs:

• 2 sheets of cardstock (or paper) for construction of model houses (alternative: use math snap cubes as houses; they won't get ruined when wet and rinse off easily when finished; need at least 6 per group; won't need template, tape, scissors or markers)
• Model House Template
• transparent tape
• scissors
• markers, colored pencils, or crayons to decorate houses
• 5-pound (2.3 kg) box of modeling clay per group (reusable)
• aluminum baking pan
• a small board (or something else rigid) to support the baking tin after inserting the clay
• clean-up supplies (paper towels, sponges, towels, etc.), for after using wet clay
• a thick book to prop up the plastic tub (may not be needed if you conduct activity outside)
• Riverbed Template, one of three designs provided

To share with the entire class:

• computer with projector to show students attached PowerPoint presentation (or print out some images from the presentation)
• computer with Internet access to show students video clips of actual river flooding
• 1 large, shallow, plastic waterproof tub (8-in x 14-in x 30-in or 20-cm x 36-cm x 76-cm, clear plastic is better but not necessary) (may not be necessary if you can conduct the activity outside)
• wire cutters or tin snips to cut the baking pan (only necessary first time) (alternative: use the plastic landform trays in FOSS Landforms kits, which are shaped like baking trays and have drain holes)
• a small paper cup, used to pour water over the riverbed model
