built a cash register out of cardboard

Science

• The student gained an understanding of the concept of money and currency exchange through the design and use of the cash register.
• They learned about simple machines and engineering principles while constructing the cardboard cash register, such as levers for the cash drawer and buttons for the calculator.
• The activity also introduced the student to the basics of electricity and circuitry through the use of simple LEDs or buzzer elements for the cash register's display or sound effects.

For continued development, students could expand on the cardboard cash register activity by incorporating additional electronic elements such as a simple Arduino circuit to control the display or even integrating a barcode scanner for more realistic functionality. They could also explore the history of cash registers and how they have evolved over time, linking to the development of technology and innovations in business. Moreover, students could consider the environmental impact of using cardboard and explore sustainable alternatives for building materials.
