Answer Key
Teacher Notes:
This worksheet reviews core computer science ideas connected to matter through data representation, modeling, sensors, simulations, and algorithms used in real-world science and technology. Suggested use: warm-up, guided practice, or independent review. Learning objectives: students will define key terms, connect computing to scientific measurement, and apply concepts to scenarios involving digital models of matter. Differentiation: support struggling learners with word banks, partner work, or sentence starters; challenge advanced learners to justify answers using examples from simulation software, lab sensors, or data analysis tools. Extension: ask students to compare a physical experiment with a computer simulation of particle behavior.
