THEME: Nature’s Design: Systems, Cycles, Patterns, Relationships, and Adaptations in the Garden System
STRAND: Energy and Matter

Key Concepts

Understand that the sun is the source of energy for all things on the planet.

Photosynthesis provides the basis for the food chain.

Compare and contrast organisms in the garden and other ecosystems.


Design an experiment where students analyze the effects of different amounts of light on germinated seedlings.

Plant 2 rows of lettuce or root crops some with shade-cloth others without. Compare and contrast the difference.

Measure temperature in compost and graph heat over stages of decomposition. Infer heat is a byproduct of the processes of cellular respiration of bacteria.

Observe how ambient temperature affects the movement of macroorganisms in the garden.


Estimate, calculate and record volume.
