Break the concept of the universe into manageable bites! This user-friendly text covers the earth, lithosphere, hydrosphere, atmosphere, and weather in 24 lessons in 30 weeks. Each unit includes: vocabulary words, Scripture quotes, coloring pages, resource list, timeline prompts, and hands-on activities, including building models, simulating volcanoes, and more. Lessons include conversational text that clearly explains new concepts in a friendly tone spoken directly to the student; notes in the margin explain unfamiliar words or concepts. Unit “wrap-ups” ensure all work is finished before moving on to a unit quiz.
