Integrated Science- Year 2 Sample Flowchart for Concept Instructional Sequence

The interaction of matter and energy results in a dynamic Earth system.

IB

Why is the sun necessary for life?

Incoming/outgoing energy: Solar energy heat

Reflection and absorption of light; photosynthesis (E4b)

Instruction will include: Solar budget Photosynthesis

How does heat produce wind and ocean currents?

Effect of Earth’s rotation (E5b)

Circulation and distribution of heat in atmosphere and ocean (E5a)

Convection: wind and ocean currents

Origins and effects of temperature inversions (E5c) Climatic bands at specific latitudes, i.e., rain forests, deserts (E5e) Climate changes over time with changes in geography, atmosphere, plate movements, etc. (E6c) How is climate different from weather? * Interaction of wind patterns, ocean currents, and mountain ranges (E5f) Latitude, elevation, topography, proximity to water, and ocean currents determine climate (E6b) Climate as long-term weather average * El Nino southern oscillation, sea surface and air temperature Transfer of energy in and out of atmosphere responsible for weather and climate (E6A) Early Earth different from Earth today (E1c)

Instruction will include: Differential heating Atmospheric circulation Ocean currents Coriolis effect Biomes Roles of convection
