LSD Unit:   2b       Michigan Curriculum Framework (2000)       "Using" Science Benchmarks

IV.2.e.1


LSD Units
 
2b
5b

Describe common physical changes in matter - size, shape; melting, freezing (K-2); dissolving, evaporating (3-5).
Key concepts: States of matter - solid, liquid, gas. Changes in size and shape - bending, tearing, breaking. Processes that cause changes of state: heating, cooling. See EH-V.2 e.1 (water in three states).
Real-world contexts: Changes in size or shape of familiar objects, such as making snowballs, breaking glass, crumbling cookies, making clay models, carving wood, breaking bones; changes in state of water or other substances, such as freezing of ice cream, or ponds, melting wax or steel, puddles drying up.

V.1.e.1

2b
4a

Describe major features of the earth's surface.
Key concepts: Types of landforms - mountains, plains, valleys; bodies of water - rivers, oceans, lakes (see EH-V.2 e.2); deserts.
Real-world contexts: Examples of Michigan surface features, such as hills, valleys, rivers, waterfalls, Great Lakes; pictures of global land features, including mountains, deserts.

V.1.e.3


LSD Units
 
2b
4a

Describe natural changes in the earth's surface.
Key concepts: Causes of changes - volcanoes, earthquakes, erosion (water, wind, gravity, glaciers). Results of change - valleys, hills, lakes, widened rivers, mountains, cracks, movement of earth materials (boulders, gravel, sand, clay).
Real-world contexts: Places around the school where erosion has occurred, such as gullies formed in down-hill gravel areas, cracks in asphalt. Places beyond the school where changes have occurred, such as volcanic mountains, shorelines, landslides, sand dunes, slopes, river valleys.

V.1.e.6


LSD Units
 
Kb Subsidiary
2b
3a

Demonstrate ways to conserve natural resources and reduce pollution through reduction, reuse, and recycling of manufactured materials.
Key concepts: Materials that can be recycled - paper, metal, glass, plastic. Conservation and anti-pollution activities - reduce, reuse, recycle.
Real-world contexts: Collections of recyclable materials, plans for recycling at home and school, composting, ways of reusing or reducing the use of paper.

V.2.e.1


LSD Units
 
2a
2b
5b

Describe how water exists on earth in three states.
Key concepts: Liquid (K-2) - visible, flowing, melting, dew. Solid (K-2) - hard, visible, freezing, ice. Gas (3-5) - invisible, water vapor, moisture, evaporating. See PCM-IV.2 e.1.
Real-world contexts: Examples of water in each state, including dew, rain, snow, ice, evidence of moisture in the air, such as "fog" on cold bathroom mirrors; examples of melting, freezing, and evaporating.

V.2.e.2


LSD Units
 
2b
4a

Trace the path that rain water follows after it falls.
Key concepts: Precipitation - see EAW-V.3 e.1. Flow - downhill, to rivers, into the ground. Bodies of water - streams, rivers, lakes, oceans. See EG-V.1 e.1 (earth features).
Real-world contexts: Examples of water flowing locally, including gutters, drains, streams, wetlands.

V.2.e.3


LSD Units
 
2b
3a

Identify sources of water and its uses.
Key concepts: Water sources - wells, springs, Great Lakes, rivers. Household uses - drinking, cleaning, food preparation. Public uses - generate electricity, recreation, irrigation, transportation, industry.
Real-world contexts: Examples of local sources of drinking water, including wells, rivers, lakes. Examples of local occasions when water is used, including car wash, swimming, fire hydrants, drinking, food preparation, cleaning, watering lawn, bathing, fishing, boating, shipping on the Great Lakes.
