Units
Unit 1
Solids & Liquids
Sorting solids and liquids, describing melting, freezing and boiling, and changes that can or can't be undone.
Learning standard: 2.PS1.4; 2.ESS2.3 · changes from heating and cooling, and water as a solid or a liquid
Unit 2
Changing Materials
Ways to change materials: cutting, bending, mixing, warming and cooling keep the same material, while cooking, burning and rusting make something new.
Learning standard: 2.PS1.1; 2.PS1.4 · describing materials and changes that can or cannot be reversed
Unit 3
Water World
The water cycle, where our water comes from, and simple ways to save water and keep rivers clean.
Learning standard: 2.ESS2.3 · where water is found on Earth and the forms it takes
Unit 4
Mixtures & Materials
Mixing liquids and solids (dissolving, separating), what sinks or floats, and which materials soak up or push away water.
Learning standard: 2.PS1.1; 2.PS1.2 · testing materials' properties and choosing the best one for a job
Unit 5
Plants, Seeds & Pollinators
Practices testing what plants need to grow, and how animals carry pollen and spread seeds.
Learning standard: 2.LS2.1; 2.LS2.2 · plants need sunlight and water, and animals pollinate plants and spread seeds
Unit 6
Fast & Slow Earth Changes
Practices sorting Earth events into fast ones (eruptions, landslides, floods) and slow ones (erosion, carving canyons), and comparing ways people slow wind and water from changing land.
Learning standard: 2.ESS1.1; 2.ESS2.1 · Earth events happen quickly or slowly, and ways to stop wind and water from changing land
Unit 7
Habitats Near & Far
Practices comparing the plants and animals that live in different habitats, from Pacific Northwest forests and tide pools to deserts and grasslands.
Learning standard: 2.LS4.1 · comparing the variety of plants and animals in different habitats
Unit 8
Oregon Land & Water
Practices naming kinds of land and bodies of water and showing them on a simple map, using Oregon places like Mount Hood, Crater Lake, the Willamette Valley, the Columbia River and the Oregon coast, and where water is solid or liquid.
Learning standard: 2.ESS2.2; 2.ESS2.3 · modelling the kinds of land and water in an area, and where water is found as a solid or a liquid
Unit 9
Build, Test & Rebuild
Practices engineering steps: asking questions to define a problem, sketching how a shape helps an object work, comparing two designs from test data, and seeing how an object made of small pieces can be taken apart and built into something new.
Learning standard: 2.ETS1.1; 2.ETS1.2; 2.ETS1.3; 2.PS1.3 · defining a problem, how shape helps an object work, comparing test data, and building new objects from the same pieces
