Activities in this unit focus on factors that impact the equilibrium of an ecosystem such as the Blackland Prairies of Texas.
The First Nine Weeks will focus on Ecoregions of Texas. Students will get to perform a Bottle Biology Lab, analyze how ecosystems maintain equilibrium and the physical properties used to classify rocks and minerals.
Enduring Understandings
Balance within systems is regulated by the interactions between biotic and abiotic factors.
Comparative and descriptive investigations are designed and implemented by making observations.
Essential Questions
How are biotic and abiotic factors connected to equilibrium in an ecosystem?
How might you justify that a microhabitat is an ecosystem?
What stores can rocks tell?
What would the history of Texas look like from a rock's point of view?
