This Grade 3 Computer Science worksheet provides a comprehensive introduction to computer hardware fundamentals. It systematically explores the four core components of a desktop computer (monitor, keyboard, mouse, and CPU box), establishing clear analogies like comparing the monitor to a TV screen and identifying the CPU as the "brain" of the system. The material expands to essential peripherals including printers, scanners, webcams, and storage devices like pen drives and CDs/DVDs, explaining each component's practical function in age-appropriate terms. Key technical concepts such as UPS (Uninterrupted Power Supply) are simplified to demonstrate real-world applications, helping young learners connect classroom knowledge to everyday technology use.
Designed for active engagement, the worksheet features diverse question formats that reinforce learning through multiple-choice exercises, true/false statements, and scenario-based applications. Students identify components by function ("Which part prints documents?"), distinguish technical terms (CPU vs. UPS), and solve practical problems ("How to bring files to school?"). The structured progression from basic identification (monitor/keyboard) to complex peripherals (scanner/projector) builds conceptual depth, while exercises like matching devices to tasks (recording songs with a microphone) develop critical thinking. This approach transforms abstract technical knowledge into tangible skills, preparing students for digital literacy in later grades.
