Chemical Bond Challenge

Through multimedia interaction, understand the formation and breaking of chemical bonds. The exhibit consists of interactive multimedia screens, where visitors wave their arms and perform actions to cut chemical bonds, forming a game of new substances. The game includes three modes: thermal energy, light energy, and electrical energy, corresponding to the three mechanisms of chemical bond breaking. The three modes appear randomly, and the light dots on the screen represent the electrons in the molecule. With different modes, different types of movements are performed, and visitors can complete the interaction by cutting off the chemical bond. This exhibit is set with a point ranking, and the challenge ranking can be viewed after the interaction ends. Through interactive games, display the types of chemical bonds, including ionic bonds, covalent bonds, and metal bonds, and understand that the essence of chemical reactions is the breaking and generation of chemical bonds. Target audience: Adolescents aged 6-15. Interactive multimedia device operation instructions (audience experience) 1 Observe the interactive prompts on the screen to understand the.

Interaction type: Interactive multimedia. The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

1. The essence of chemical bonds is the interaction of electrons. In molecules, atoms form chemical bonds by sharing or transferring electrons. The sharing or transfer of these electrons forms a stable structure within the molecule, giving it a certain degree of stability and chemical reactivity. (1) Ionic bonds are chemical bonds formed through electron transfer. In ionic bonds, atoms transfer electrons to each other to form positive and negative ions, thereby forming a stable structure. This type of electron transfer typically occurs between metals and non metals, such as sodium ions and chloride ions in sodium chloride binding through ionic bonds. (2) Covalent bonds are chemical bonds formed through electron sharing. In covalent bonds, atoms form stable molecular structures by sharing electron pairs. Covalent bonds usually occur between non metals, such as oxygen and hydrogen atoms in water molecules bonded through covalent bonds. (3) Metal bonds are formed through the chemical process of electron oceans.
