摘要:
Modular frames for instructional use that provide secure mounts for geometric solids are presented. Some contemplated modular frames can be assembled into three dimensional modular devices and are particularly suitable for instructional purposes. Modular devices comprising two or more frames could be coupled via a clip in two or more different configurations. Containers including conductive material and configured to provide a Faraday cage around their contents are also provided.

A non-transitory computer-readable medium storing instructions executable by a hardware processor to create a plurality of adaptive grids, present an adaptive hexagon grid in a drawing window on a display, prompt a user to create a first chemical structure on the adaptive hexagon grid, present a first plurality of atomic bond representations on the display, receive a first location selection chosen by the user from the adaptive hexagon grid, present a first plurality of atomic bond representations on the display, receive a first atomic bond selection chosen by the user from the first plurality of atomic bond representations, and present the first atomic bond selection at the first location selection on one of the plurality the adaptive grids. The first plurality of atomic bond representations include at least a single covalent bond representation and a double covalent bond representation.

Systems that are used to support a plurality of frames arranged in a specific configuration are contemplated. The system comprises outer frame panels that removably couple to the plurality of frames. It is contemplated that the outer frame panels collectively couple to the plurality of frames to thereby provide additional stability to maintain the plurality of frames in the specific configuration, such that the risk of the plurality of frames losing their specific configuration during transport is reduced.

A construction teaching set for education. A polyhedral block body has first and second divided members and provided by engaging and assembling of the first and second divided members. Each of the first and second divided members has a rectangular plane, a plurality of rectangular inclined surfaces adjoining sides of the rectangular plane, triangular connectors formed between the adjacent rectangular inclined surfaces, and a plurality of vertical skirts extending from the plurality of rectangular inclined surfaces and the triangular connectors. A connection bar has a protruding fastener at one end or both ends to be selectively connected to one among a first fastening hole passing through the rectangular plane, second fastening holes passing through the plurality of rectangular inclined surfaces, and third fastening holes formed in a pair of the vertical skirts adjoining each other. A coupling unit generates coupling force for the first and second divided members.

A kit of educational building blocks includes a first set of amino acid side chain building blocks, each amino acid side chain building block corresponding to a distinct one of 20 distinct amino acid side chains, a second set of identical amino end building blocks, each amino end building block having a first end configured to removably engage with the amino acid side chain building blocks to form an amino end-side chain block combination, and a third set of identical acid end building blocks, each acid end building block having a first end configured to removably engage with amino end-side chain block combination to produce an amino acid building block assembly. The first, second, and third set of blocks are configured so that a plurality of amino acid building block assemblies can be linked to one another so as to model a series of linked amino acids in a protein.
摘要:
A three-dimensional object formation instruction apparatus receives information pertaining to distribution of a predetermined physical quantity in a three-dimensional space, and on the basis of the received information, determines a shape of a representation body representing the physical quantity, and then, on the basis of the received information, determines a position at which the representation body representing the physical quantity is to be arranged. The three-dimensional object formation instruction apparatus generates a three-dimensional object formation instruction including an instruction to form an object having the determined shape at the determined position, and outputs the generated instruction.

A system and method for guided or unguided instruction, comprising a color, or/and a tactilely coded list of most common ions, and a set, of blocks corresponding to a chart, sufficient to represent formula units in any possible combination of ions coded in the chart, is provided. A valid ionic compound (formula unit) model constructed with the present invention is represented by a rectangular, or cuboid, shape having six sides and eight corners and no more than two ionic types represented by blocks having ionic coding.

The present disclosure provides a modeling apparatus having a plurality of modeling devices, each having a generally tetrahedron shape having four faces with an interface element attached to each face. Each interface element cane b removably and rotatably coupled to an interface element of an adjacent modeling device. A combination of modeling devices are selectively couplable to form a variety of structures such as molecular, architectural, artistic, dynamic, and/or any other suitable model. The interface elements can include magnets with distinct or identical polarities, and with selective strengths to emulate the target structure or assembly attributes. They can also be iron or a neutral material such as aluminum. The vertices of the modeling apparatus include a curvilinear boundary tracing a spherical periphery of a sphere having a radius extending from a center point of the tetrahedral shape to a midpoint of an edge thereof.

A system of construction that uses a discrete repertoire of elastic modular units that interconnect forming assemblies of diverse curved geometries applicable at any scale.Each modular unit is formed with linear elements with less than infinite elastic modulus. The modular units connect to one another under tension creating structural networks that have stored elastic potential energy.The linear elements may be formed of carbon based composite materials and their future permutations, including smart materials. The modular assemblies created using this system have application in terrestrial, space and aquatic environments and as an educational tool.

A molecular modeling kit provides a system for molecular modeling that represents exclusion between resonance structures in a molecule and permits their rotation, providing an informative tool for describing resonance in a classroom or other learning environment. The kit includes atom modeling components and bond connector components that are connected together to form models of molecules. The atom modeling components or the bond connector components include a mechanical exclusion feature that prevents simultaneous connection of two bond connector components to represent two pi-bonds formed with a single atom in a single plane.
