DENSITY, BUOYANCY & MEASUREMENT, CONTINUEDDensity Box—Demonstration KitIn this clever density demonstration, the clear acrylic chamber is divided in half by a removable wall. Hot, red water is on one side and cold, blue water on the other. When the dividing wall is removed, the two solutions mix and dramatically separate with the hot, red water on top and the cold, blue water on the bottom. Great for discussing convection currents, air turbulence and water turnover. Includes instructions and teaching tips. AP4784 I $37.25Grow-Dino Measurement—Student Laboratory KitProvide practice in measuring, graphing and making calculations as students investigate whether Grow-Dinos really grow more than 600% in water. Students daily measure and graph the length, height, thickness, perimeter, area, volume, mass and density a polymer dinosaur over a period of five days for analysis. Includes Teacher Notes, student handouts with data tables and graph sheets, 15 Grow-Dinos, metric rulers, storage bags and measuring string. AP6127 I $33.50It’s All About Density—An Introductory Super Value Activity-Stations KitIntroduce density as students determine mass and volume of seven different materials—vari-ously shaped solids and two liquids. Students measure volume with a ruler and water displacement. Activity stations allow groups to rotate among materials. Includes instruc-tion masters, pre-lab activity, background information, post-lab questions and all mate-rials (except distilled water). Super Value Kit is for seven lab stations with two setups at each. AP6153 I $31.55Discovering Buoyancy—Super Value Guided-Inquiry KitStudents discover buoyant forces and volume by submerging objects like Archimedes did in Ancient Greece. Students collect data and investigate forces acting on identical volumes of four materials then compare and analyze the results and reconstruct Archimedes’ Principle. Students complete five activity stations in any order. Includes student handouts and Teacher Notes. Super Value Kit is for 10 student groups. Includes four 5-N spring scales. AP7627 I $66.85Density Cube SetThis is a handy, low-cost set of 10 one-inch cubes cut from modern materials. Use these precision cubes to perform a variety of density experiments. The set contains one cube each of aluminum, steel, brass, copper, acrylic, Nylon®, poplar, oak, willow and polythylene. AP6058 I $36.20Equal Mass Kit—Classroom SetMass, volume and density are taught through-out the year in many ways. Help students understand relationships between these concepts with the Equal Mass Kit. Cylindrical objects of different materials with differing lengths all have the same mass and radius, showing density as inversely proportional to length. Contains five 15-g, ½”-diameter cylinders of brass, aluminum, nylon, PVC and polyethylene. Classroom set includes 15 sets of materials.AP6147 I $131.90Specific Gravity Specimens, Set of 10Determine the specific gravity of ten different materials and then use the density values to identify each material. Set of 10 specimens includes aluminum, brass, copper, glass, graphite, lead, polyvinyl chloride, polyeth-ylene, steel and polystyrene. Four-page handout includes background, lab activity procedure and reproducible student data table, calculations and questions.AP9235 I $16.05
