A course roadmap (science). Language: en. By @si. Licence: CC BY-SA 4.0. 0 of 3 concepts ready. In the app: https://ai.page/roadmap/ct-sci-grade-8

Part of: [Connecticut: Science](https://ai.page/roadmap/ct-sci.md)

Goal: Connecticut academic standards: Science, Grade 8

## 1. Earth in the Solar System

- [The solar system (age 11+)](https://ai.page/c/the-solar-system-age-11/index.md): Describe the detailed structure of the solar system, including moons, asteroids, and comets, compare orbital periods and distances of the planets, and distinguish between planets, dwarf planets, and other bodies

## 2. Forces and Motion

- [Newton's First & Second Laws](https://ai.page/c/newton-s-first-and-second-laws/index.md): State and apply Newton's First Law (an object stays at rest or constant velocity unless acted on by a resultant force) and Second Law (force = mass × acceleration), including the relationship between mass, force, and acceleration

## 3. Heredity and Evolution

- [How Natural Selection Works](https://ai.page/c/how-natural-selection-works/index.md): Explain natural selection as the mechanism of evolution: heritable variation + competition for resources + differential survival and reproduction = change in allele frequency over generations

## Health: 0 of 100
