Units
Unit 1
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.P1U1.1; 2.P4U1.3 · describing materials, and how heat can change them
Unit 2
Solids & Liquids
Sorting solids and liquids, describing melting, freezing and boiling, and changes that can or can't be undone.
Learning standard: 2.P1U1.2 · how heating or cooling changes a substance between solid and liquid
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.E1U1.5 · water as a solid, liquid or gas, and where it is found on Earth
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.P1U1.1 · matter has mass, takes up space and is recognized by its properties
Unit 5
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.E1U1.4; 2.E1U3.7 · how wind and water change the shape of the land

Unit 7
Weather Hazards & Solutions
Practices judging design solutions that reduce harm from weather hazards like floods, windstorms, lightning and snow, and solutions to problems when habitats change.
Learning standard: 2.E1U2.6 · weather in different regions, and designs that reduce the harm of weather hazards
