Units
Unit 1
Solids & Liquids
Sorting solids and liquids, describing melting, freezing and boiling, and changes that can or can't be undone.
Benchmark: 2P.1.2.1.1 · how heating and cooling affect different materials
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.
Benchmark: 2P.3.1.1.1 · changes from heating or cooling that can and cannot be reversed
Unit 3
Push & Pull
Pushes and pulls, magnets, gravity, and how surfaces slow things down.
Benchmark: 2P.2.2.1.1; 2P.1.1.1.1 · balanced and unbalanced forces, and asking questions about how objects move
Unit 4
Water World
The water cycle, where our water comes from, and simple ways to save water and keep rivers clean.
Benchmark: 2E.4.2.1.1 · where water is found on Earth
Unit 5
Weather & Seasons
Dressing for the weather, the four seasons in order, day and night, and how plants and animals change with the seasons.
Benchmark: 2E.2.1.1.1; 2E.4.2.1.2 · the weather expected in each season, and climates in different places
Unit 6
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.
Benchmark: 2E.2.1.1.2 · testing designs that lessen the harm from weather hazards
Unit 7
Plants, Seeds & Pollinators
Practices testing what plants need to grow, and how animals carry pollen and spread seeds.
Benchmark: 2L.3.2.2.1; 2L.4.1.1.1 · how seeds are spread, and which plants and animals survive well in a habitat
