gathering and evaluating information. We want to make science accessible and relevant to the general public.

Students will be introduced to the subject of dendrochronology — the study of time using trees, specifically the annual growth rings in trees. Students in this class will have a hands-on exploration of tree “cookies” or cross sections of trees to better understand how dendrochronology has influenced forest ecology, archaeology, and climate change.</p> <p><em>Location:</em> Portable Classroom Visit/LTRR</p> </p></div></div> <div class="card"><div class="card-header"><div class="card-title"> <h4 class="card-title">Investigating Artifacts: Uncovering the Past through Middens</h4> </div></div><div class="card-block"><p class="card-text"> <p>The science of archaeology often focuses on old village sites known as “middens”. Middens are deposits people have left behind, the remains of settlements, the “garbage dumps” of long lost communities. In this session, students will examine “middens” representing sites of prehistoric Hohokam people at Tumamoc. After a demonstration of the procedures that will be used to excavate the site, teams of students act as archaeologists working together to excavate objects form the layers of the soil in shoe box “middens”. Students learn that materials discarded or lost by people long ago can provide valuable clues for reconstructing a picture of an earlier culture. While practicing the methods of archaeologists, students infer information from objects, group objects, and share drawings and explanations from clues of the past.</p> <p><em>Location:</em> Portable Classroom Visit/LTRR</p> </p></div></div> <div class="card"><div class="card-header"><div class="card-title"> <h4 class="card-title">Field Class: Middle Bear Canyon, Catalina Mountains Day Trip</h4> </div></div><div class="card-block"><p class="card-text"> <p>Dendrochronology is a retrospective science that can provide glimpses into our environment long before humans altered the natural environment. Students will be introduced to the subject of dendrochronology - the study of time using trees, specifically the annual growth rings in trees. Students in this class will have a hands-on experience learning to sample and core trees. We continue our exploration of Mt. Lemmon and look at the urban-wildland interface by exploring the landscape around Summerhaven to better understand fire history and forest management practices. We continue our exploration up Mt. Lemmon to another field study site to calculate plant densities in plots, where students will then analyze their results.</p> <p><em>Location:</em> Catalina Mountains</p> </p></div></div></div></div> </div> </div> <div class="entity entity-paragraphs-item paragraphs-item-uaqs-card-deck mb-4 default"> <div class="content"> <div class="card-deck-wrapper"><div class="card-deck uaqs-card-deck-width-two-cards"> <div class="card"><div class="card-header"><div class="card-title"> <h4 class="card-title">Ecology: Introduction to Cactus Surveys - Currently not Offered</h4> </div></div><div class="card-block"><p class="card-text"> <p>Students will survey cactus species and perform a spatial analysis of the plants.
