Units
Unit 1
Solids & Liquids
Sorting solids and liquids, describing melting, freezing and boiling, and changes that can or can't be undone.
Content standard: 2.1; 2.4; 2.9 · sorting solids and liquids by their properties, and heating and cooling changes
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.
Content standard: 2.2; 2.4 · choosing materials for a job, and changes that can or cannot be undone
Unit 3
Mixtures & Materials
Mixing liquids and solids (dissolving, separating), what sinks or floats, and which materials soak up or push away water.
Content standard: 2.1; 2.2 · classifying materials by properties and choosing the right one for a use
Unit 4
Objects & Structures
Structures that hold up a load, what everyday objects are for, how fasteners join things, and where materials such as wood and wool come from.
Content standard: 2.2; 2.3 · what structures are made of and how their parts fit together
Unit 5
Plants, Seeds & Pollinators
Practices testing what plants need to grow, and how animals carry pollen and spread seeds.
Content standard: 2.5; 2.6 · testing one variable at a time on plant growth, and how animals spread seeds and pollen
Unit 6
Plant Experiments
Children sort seeds, predict and test which conditions help plants grow, and record and graph plant growth. This is practice, not a report-card mark.
Content standard: 2.5 · fair tests that change one condition to see how plants grow
Unit 7
Water World
The water cycle, where our water comes from, and simple ways to save water and keep rivers clean.
Content standard: 2.8; 2.9 · oceans, lakes and rivers, and where water is solid or liquid on Earth
Unit 8
Habitats Near & Far
Your child learns that many kinds of plants and animals live in habitats on land and in water, with examples from Alabama.
Content standard: 2.7 · the many kinds of living things in habitats on land and in water
Unit 9
Land & Water Maps
Your child names the shapes and kinds of land and water on Earth and finds them on simple maps and models, with Alabama examples.
Content standard: 2.8 · the shapes and kinds of land and water on Earth, shown on models and maps
Unit 10
Fast & Slow Earth Changes
Your child learns that some changes to the land happen fast and some slowly, and compares ways to slow wind and water from wearing land away.
Content standard: 2.10; 2.11 · earthquakes, floods and erosion, and designs that protect the land
Unit 11
Changing Land
Your child sorts changes to the land into fast and slow, and looks at ways people keep soil and shorelines from washing away.
Content standard: 2.10; 2.11 · fast and slow changes to the land, and ways to stop wind and water wearing it away
