Crystalline Solids Model Kit
By: The Flinn Staff
Assemble the crystal structures of many metals with this
large-scale model kit. Use the stunning, three-dimensional arrangements of atoms to explain and predict many of the physical properties of common metals. Because the two closest-packing structures, cubic and hexagonal closest packing are very similar, many students find it difficult to visual- ize the differences between them. Once assembled, the sturdy model can be passed around for students to create both structures and identify their unique features. Bring clarity to what is certainly a “fuzzy” image in most students’ minds. Demonstration Notes included.
Models of Ionic and Metallic Crystals Kit
By: The Flinn Staff
Display ionic and metallic models at the same time!
Compare the different structures and arrangements of an ionic solid versus a metallic solid. Assemble any of the five different arrange- ments—face-centered cubic, body-centered cubic, simple cubic, hexagonal closest packing and cubic closest packing. Models are 8" x 8" x 8". Kit contains two machined bases, 22 support rods, 14 3-inch diameter spheres, 14 21⁄2-inch diameter spheres and 13 2-inch diameter spheres. Detailed Assembly and Demonstration Notes are included.
Student Molecular Model Kit
For individualized student use; kit includes student instructional manual. Your students will learn bonding capacity, molecular shape, reactivity, multiple bonding, and isomers. This very inexpensive but practical kit includes: 15 2"-diameter colored Styrofoam® balls, 15 1"-diameter white balls, toothpicks and pipe cleaners for single and multiple bonds, a jig for tetrahedral molecules, and a 14-page instruction booklet.
Advanced Molecular Model Set, 121-piece
You’ve requested it and it’s here. A kit that can be used for demon- strating not only organic structures, but also inorganic structures and molecular geometry. Use these colorful, sturdy, wooden models to help your students visualize molecules, such as C4H10, C4H8, BeH2, CCl4, XeF4, PF3Cl2 and SF6. Show saturated, unsaturated and substituted organic compounds as well as different types of isomers. Illustrate linear, trigonal planar, square planar, trigonal bipyramidal and octahe- dral geometry. This advanced set contains 71 color-coded, enameled wood balls drilled to receive wooden or spring bonds (50 bonds provided). Specific contents of set:
Balls—11⁄4" diameter
• 12 carbon (black) – tetrahedral 4-hole
• 2 nitrogen (blue) – tetrahedral
• 2 phosphorus (gray) – trigonal bipyramidal • 2 sulfur (yellow) – octahedral
