After your group explores the Arcadia Earth app section titled Keep the Great Lakes GREAT! and are introduced to challenges the amazing Great Lakes face, learners investigate their own use of a precious resource, water. The lesson culminates with learners developing strategies to conserve water and identifying how they can play a part in keeping our Great Lakes Great!

How do ecosystems work, and how can understanding them help us protect them? In this unit, students investigate the 30 by 30 initiative, a proposal to protect 30% of US lands and waters by 2030, and the reasons humans engage in conservation. Students use the Serengeti National Park as a case study to figure out ecosystem and conservation principles and apply those understandings to conservation dilemmas in the US.

What causes fires in ecosystems to burn, and how should we manage them? What causes fires in ecosystems to burn, and how should we manage them? This unit is designed to help students build a deeper understanding of the flow of matter and energy within ecosystems and the cycling of carbon on a global scale due to increased fires. Students read about mysterious arctic fires popping up near the burn scars of old fires and do a visual inquiry to obtain more information about what is happening with matter and energy in these arctic fire systems. To figure out how these fires can burn under ice and release so much carbon dioxide, students explore the interactions between peat, permafrost, decomposers, the sun, and other components of the system by investigating burning fuels, measuring the rate of decomposition and photosynthesis under different conditions. Students are motivated to see if they can generalize this phenomenon to other systems and the effect of increased carbon dioxide on the atmosphere. Students quantitatively model how matter and energy flow through different earth systems and different levels within an ecosystem. Finally, students use what they have figured out about positive feedback effects to design solutions to disrupt that flow of matter and energy in communities they care about.

How does urbanization affect nonhuman populations, and how can we minimize harmful effects? How does urbanization affect nonhuman populations, and how can we minimize harmful effects? This unit on natural selection and evolution of populations focuses on the phenomenon of increasing urbanization around the world and the impact of that change on nonhuman populations. Students investigate case studies that investigate fragmentation, poison, and proximity to humans as selection pressures that affect the relative fitness of individuals with particular anatomical, physiological, and behavioral traits in a population. Through investigations with complex data sets, they figure out how genetic diversity in a population allows populations to adapt to changes encountered in urban environments.

Students are introduced to the concept of engineering biological organisms and studying their growth to be able to identify periods of fast and slow growth. They learn that bacteria are found everywhere, including on the surfaces of our hands. Student groups study three different conditions under which bacteria are found and compare the growth of the individual bacteria from each source. In addition to monitoring the quantity of bacteria from differ conditions, they record the growth of bacteria over time, which is an excellent tool to study binary fission and the reproduction of unicellular organisms.

In this inquiry activity, students generate investigable questions to explore the link between hygiene/cleanliness and bacteria growth/population. The students will present their conclusions, and video clips containing additional information will be discussed.

This animation describes how bacteria are cultured in the lab and the different phases of bacterial growth, including lag, log, stationary and death.
