En esta lección, los estudiantes aprenderán a transformar aplicaciones estáticas en interfaces interactivas mediante el uso de TouchableHighlight y la actualización del estado (setState) en React Native dentro del entorno CodeHS.

A comprehensive set of practice problems covering the six fundamental gas laws: Boyle's, Charles's, Gay-Lussac's, Ideal, Combined, and Dalton's law of partial pressures.

A comparative study of geomorphology, exploring how liquid properties (viscosity, density, and flow) shape land formations on Earth and other celestial bodies like Mars, Titan, and Venus.

An immersive exploration of liquid properties—viscosity, density, capillary action, and intermolecular forces—comparing water to various common fluids through hands-on experimentation and data analysis.

A hands-on gallery walk activity where students explore the history and tenets of cell theory by visiting scientific 'exhibit' stations and completing a chronological discovery log.

A focused lesson on the fundamental laws of electricity, covering Ohm's Law for circuits and Coulomb's Law for electrostatic forces through conceptual analysis and calculation practice.

A deep dive into the industrial processing of seed oils, their prevalence in modern diets, and how to identify them on food labels. Students will explore the journey from crop to bottle and become 'oil detectives' in the grocery aisle.

A comprehensive biology lesson covering genetics (transcription/translation), evolutionary classification, and ecological succession, designed to mirror the rigor and format of the Texas EOC.

A comprehensive midterm review for CS10 covering NC standards for data representation, cybersecurity, and basic programming logic. Includes a detailed study guide and a 75-question practice exam.

A comprehensive look at the structural differences between plant and animal cells, using a technical blueprint aesthetic to explore organelles and their functions.

An exploration of data collection methods, storage formats, and the practical implications of data management in computer science. Students will identify data sources and compare storage solutions.

This lesson compares linear and rotational motion through a case study of a high-tech amusement park ride. Students explore the analogies between force and torque, mass and inertia, and work/power/conservation laws in both systems.

This lesson compares linear and angular motion through a multi-part reading assignment, including an informational article, a textbook excerpt, and a case study. Students will identify key formulas and physical principles.

Cette séance de 2 heures permet aux élèves de distinguer qualification et compétence, d'analyser l'impact des conditions de travail sur le comportement des salariés et de mesurer la performance de l'activité humaine via des indicateurs de productivité et de climat social.

A comprehensive introduction to cybersecurity for secondary students, focusing on threat identification, personal data protection, and safe online habits through case studies and practical protocols.

A project-based lesson where students learn algorithmic thinking by designing game mechanics using flowcharts and pseudocode with a retro arcade theme.

Students will learn to track energy transformations in simple harmonic motion, understanding how kinetic and potential energy exchange while maintaining a constant total energy.

A comprehensive look at simple harmonic motion, focusing on the relationship between restoring forces and displacement, Hooke's law, and real-world oscillatory systems.

A 100-minute intensive lesson covering the four experiences of animal systems: organization, nutrient regulation, reproduction, and environmental response. Includes an outdoor observation activity to analyze animal behavior and responses in real-time.

Analyze how the nervous, muscular, and integumentary systems work together to detect and react to external changes.
