Science resources by month:
The **Great Minds® PhD Science®** curriculum for **2nd Grade (Level 2)** is an inquiry-driven, phenomenon-based program. Instead of memorizing isolated facts, students explore real-world, anchor phenomena to build deep, three-dimensional scientific knowledge.
Spread across a standard **academic year**, the curriculum is divided into **four comprehensive modules**.
Each module spans roughly **2 to 2.5 months**, integrating physical science, earth science, life science, and engineering design.
## 2nd Grade PhD Science: Topical Breakdown
### 🍂 Months 1–2: Module 1 – Matter (Physical Science)
* **Anchor Phenomenon:** How and why different kinds of birds use specific materials to build their nests.
* **Core Concepts:**
* **Describing & Classifying:** Investigating and classifying different types of matter based on observable properties (e.g., color, texture, flexibility, hardness).
* **Properties of Materials:** Understanding how the properties of small pieces or materials (like twigs, mud, and feathers) make them suited for a specific purpose.
* **Assembling & Disassembling:** Discovering how objects can be built up from a small set of pieces and broken back down into components.
* **Application / Engineering Challenge:** Students examine how temperature changes or physical mixing alters materials, helping them understand that some changes (like freezing water) can be reversed, while others (like baking or burning) cannot.
### ❄️ Months 3–4: Module 2 – Earth Changes (Earth & Space Science)
* **Anchor Phenomenon:** Rapid and slow changes to the Earth's landscape (often anchored around a specific event like the 1900 Galveston Hurricane or the formation of canyons).
* **Core Concepts:**
* **Slow Earth Changes:** Exploring how wind and water shape the land over long periods through erosion, weathering, and deposition (e.g., how water carves out valleys).
* **Rapid Earth Changes:** Investigating sudden geological events such as volcanoes, earthquakes, and landslides.
* **Mapping Landforms:** Learning how to identify and map landforms and water bodies on Earth.
* **Application / Engineering Challenge:** Designing solutions to slow down or prevent wind/water from changing the shape of the land (e.g., building models of retaining walls or dikes to protect a simulated shoreline).
### 🌱 Months 5–6: Module 3 – Plants (Life Science)
* **Anchor Phenomenon:** Plant growth, reproduction, and dependence on their environment (such as how butterflies or bees interact with specific plant life to survive over time).
* **Core Concepts:**
* **Plant Needs:** Investigating what plants need to survive and grow, specifically testing the necessities of sunlight and water through hands-on experiments.
* **Pollination & Seed Dispersal:** Understanding the vital relationship between plants and animals. Students learn how animals help plants reproduce by moving pollen and seeds from place to place.
* **Plant Structures:** Observing the functions of roots, stems, leaves, and flowers.
* **Application / Science Challenge:** Conducting controlled experiments to observe plant growth under varying conditions, and modeling how different seed structures (like burrs that stick or wings that fly) aid in dispersal.
### ☀️ Months 7–9: Module 4 – Biomes / Biodiversity (Ecosystems & Habitats)
* **Anchor Phenomenon:** Life in unique habitats, such as life surrounding a mangrove tree, a desert environment, or the elevation changes of Mount Everest.
* **Core Concepts:**
* **Diversity of Life:** Comparing the variety of plants and animals living in different habitats (terrestrial, aquatic, desert, forest).
* **Habitat Suitability:** Exploring why certain organisms thrive in their specific environments while others cannot survive there.
* **Interdependence:** Mapping out how living things rely on both the living (biotic) and non-living (abiotic) parts of their environment to meet their needs.
* **Application / Socratic Seminar:** Synthesizing the entire year's knowledge by evaluating how changing environments impact biodiversity, and how living things adapt to variations in their habitats.
