Teachers are developing unique teaching aids to attract students to the field of chemistry. Ideal teaching aids are tools that students can enjoy utilizing, reutilizing, and which can be constructed without employing special tools. LEGO®-based teaching aids satisfy all these requirements. Chemistry teachers have employed bricks to illustrate basic chemical concepts. Moreover, LEGO-based chemistry teaching aids have been vigorously reported by Campbell and coworkers since the late 1990s and are still being persistently reported by several groups. The focus of this review is the applications of LEGO bricks in teaching chemistry. This review describes LEGO-based teaching aids that are easily constructed and may be beneficial to readers, in terms of creating new teaching aids. Since LEGO bricks possess varieties of shapes and colors, they can be employed to design various teaching aids, including periodic tables, molecular models, polymer structure models, and frameworks for handmade measuring instruments. The polymeric structure models are generally difficult to build with typical ball-and-stick type molecular models; however, they can be easily built, employing LEGO bricks. The bricks are suitable for the construction of handmade measuring instruments because of their versatility and computer interface, as well as their non-requirement of special tools.

“…The solidified mixture is then pressed into interlock brick molds placed on a base, labeled accordingly, and left to dry for approximately 28 days. This methodology, as outlined by the researchers [9,[19][20] ensures the creation of interlocking bricks with robust structural integrity and dimensional stability. The study's focus on material composition and drying time, as well as the utilization of hydraulic machinery, highlights the meticulous approach taken in producing these innovative bricks, offering insights into the practical aspects of interlock brick manufacturing.…”

Interlock brick is an environmentally friendly substitute for house wall materials because the manufacturing process is not burned like red brick. This method of installing interlocking walls, like Lego, can function as a structure for sluice gates, columns and ring beams without the need for plastering or painting, so it is more effective and efficient and can reduce cement consumption. Several actions must be taken to minimize the use of cement by using environmentally friendly materials. One of the environmentally friendly materials that will be researched is Interlock bricks made from a mixture of Fly Ash . This research aims to determine the compressive strength and water absorption capacity of Interlock bricks mixed with Fly Ash. The research method begins by looking for interlock brick parameter data in the form of compressive strength and water absorption capacity. Compressive strength is a parameter of the mechanical suitability of interlock bricks , while water absorption is the ability of a material to absorb water. There are 3 variations of the mixture, namely with the ratio Fly Ash : Sand: Cement, mixture I (3: 3: 1) Fly Ash 43% , mixture II (4 : 3 : 1) Fly Ash 50% , and mixture III (5 : 3 : 1) Fly Ash 56% calculation divided based on the percentage of the amount of Fly Ash , obtained the compressive strength value of Interlock brick from the Fly Ash mixture in mixture I 16.0 kg/m2 and water absorption capacity 20%, mixture II 24.7 kg/m 2 and strength water absorption 17.5%, mixture III 10.3 kg/m 2 and water absorption 21.8%. According to SK-SNI-S-04-1989-F Interlock brick mix II with a Fly Ash composition of 50% is close to class K25 (25 kg/m 2 ) and has an absorption capacity value of <20.0% according to the absorption capacity limit based on SNI 15- 2094-2000.Keywords: Interlock Bricks, Fly Ash, Compressive Strength, Water Absorption.

“…The interlocking toy brick chemistry demonstration outlined here was the second of several PERCEIVE (Preparing Engaging Real-time Chemical Education Interactive and Visual Examples) demonstrations employed while the lecturer bridged chemistry topics with healthcare practices, and introduced the Fall 2022 semester of a Chemistry for Health Professions course, in which BSN students assembled and worked a chemistry for health professions lecture demonstration. Interlocking toy bricks (or building bricks: LEGO) have been useful for other chemical education topics, such as transcribing ionic compound formulas, kinetics and equilibrium, , polymers, and green chemistry . With considerations for accessibility, the use of interlocking toy bricks offers a tactile (i.e., manipulative) learning experience for vision impaired students in a chemical education learning environment .…”

For decades, chemical modeling sets have allowed the user to manipulate atoms and bonds using plastic/wooden ball and stick materials. Here is a design for an interlocking toy brick modeling set in which the undergraduate nursing student can manipulate electrons during the simulated chemical bonding exercise. The author presents a teaching and learning activity/demonstration designed to help undergraduate nursing (BSN) students both visualize and physically manipulate (“handle”) abstract chemical education topics such as valence shell electrons and molarity (with manipulatives for solubility rules) of salts, acids, and bases in a chemistry for health professions didactic course, as an effort to increase comprehension of these chemical education topics. This learning tool was one in a series of newly coined “PERCEIVE” (Preparing Engaging Real-time Chemical Education Interactive and Visual Examples) chemical education demonstrations, where BSN students prepare engaging demonstrations, while working in groups. The preparation (building) step allows students to get a “handle” on how the chemistry concept works. Afterward the newly prepared demonstrations are utilized as examples for chemical education and chemistry in health topicshence, the “PERCEIVE” acronym. This publication outlines: (i) Connections between Molarity and Solubility in modern healthcare practices, (ii) The method and materials for using interlocking toy bricks selected according to CPK color-scheme for modeling valence shell electrons (based on Bohr models), (iii) Solubility rules, (iv) Molarity (and calculations), and (v) Results from anonymous pre- and postqualitative student questionnaires. Student responses indicated a marked increase in the ability to calculate molarity in different volumes (1 L vs 500 mL) postdemonstration. Additional qualitative surveys were conducted, and the results highlighted more than 90% of 152 respondents endorsed the continued implementation of this demo in subsequent chemistry for health professions courses.
