Tumacácori sits at a cultural crossroads in the Santa Cruz River valley. Here O’odham, Yaqui, and Apache people met and mingled with European Jesuit and Franciscan missionaries, settlers, and soldiers, sometimes in conflict and sometimes in cooperation. Follow the timeworn paths and discover stories that connect us to enduring relationships, vibrant cultures, and traditions of long ago.

Science Will Save the World! Episode 3: We’ve Got Chemistry! (Acid and Base Experiment)
With Jessie Rack
Today we are exploring the wonderful world of chemistry with an acid-base experiment. Using household ingredients, we create a reaction that (if we’re lucky) makes a Ziploc bag explode!
1/2 cup Vinegar
2 Tablespoons Baking Soda
Ziploc bag Paper towel (ripped into a square)
3/4 cup water
Food coloring (optional)
Atom – the teeny-tiny building blocks that make up all matter in the universe. Kind of like Legos.
Ion – atoms or groups of atoms with an electrical charge, either positive or negative.
Acids and Bases – special chemicals that contain lots of ions, which makes them want to react with each other. Acids have lots of positive ions; bases have lots of negative ions.
*** Higher-Level Science Explanation:
What’s really happening here is a two-part reaction.
n step one, vinegar (acetic acid) reacts with the baking soda (sodium bicarbonate) to form sodium acetate and carbonic acid.
In step two, the carbonic acid immediately falls apart into carbon dioxide and water. The bubbles you see are the carbon dioxide leaving the solution!
Equation: (for proper notation, see https://www.thoughtco.com/equation-fo…)
Step 1: Sodium bicarbonate + acetic acid → sodium acetate + carbonic acid NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3
Step 2: Carbonic acid → water + carbon dioxide H2CO3 → H2O + CO2

Science Will Save the World! Episode 2: Sky Island Field Trip
With Jessie Rack
The word of the day is biome! You can think of a biome as a “nature zone” – a zone that’s defined by what kind of plants live there. Mountains in the Sonoran Desert are special because they are sky islands – as you go up the mountain, it gets cooler and wetter, which means the nature zones change with elevation. Let’s go on a field trip up a sky island in Arizona! Biomes we experience today: Desert Grassland Deciduous Forest (trees that lose their leaves. This one is an oak forest) Chaparral Coniferous Forest (trees with needles) Can you draw your own sky island? Draw a mountain where the nature changes as you go up it. Feel free to use your imagination! I’d love to see what you come up with.
This video was filmed at various points on Babad Do’ag, also known as Mount Lemmon, in Tucson, Arizona. Once again, this production is brought to you by the University of Arizona’s Community and School Garden Program. And Penny!
PS: Most of what I know about sky islands was gained by reading A Natural History of the Sonoran Desert, published by the Arizona-Sonora Desert Museum (https://www.desertmuseum.org/) Interested in learning more about sky islands or about conserving these amazing places?

Science Will Save the World! Episode 1: How to Make a Homemade Magnifying Glass
With Jessie Rack
Stuck at home? Why not do some science? Today, with the help of Penny the Cat, I demonstrate how to make a homemade magnifying glass with things you probably have around the house. I’ll also explain how it works – through the science of vision and light, and the power of lenses.
Come for the science, stay for the awkward sound effects and the time Penny knocks stuff off the couch. This production brought to you by the University of Arizona’s Community and School Garden Program. And Penny!
Who Pooped in the Garden? Worm Science with Jessie Rack
Regeneration! Multiple hearts! High-quality poop! Earthworms are amazing creatures and a super important part of the garden ecosystem.
Ecologist Jessie Rack is here to shout about earthworm science in the garden! Jessie is the Environmental Education Program Coordinator of the University of Arizona’s Community and School Garden Program.
Our parent organization, NAAEE’s mission is to “bring the brightest minds together to accelerate environmental literacy and civic engagement through the power of education.” Filled with a variety of resources and information, including learning opportunities and an international conference planned in Tucson, Arizona, for October 2020. Includes most recent State Environmental Literacy Plan Status Report (2014), and EEPro, an online platform for environmental education professional development and resources, open to all.
The Prescott College Center for Nature and Place-Based Early Childhood Education was established to support and expand training for early childhood educators, pre-service teachers, administrators, and program directors in developmentally appropriate nature and place-based pedagogy. Founded in 2016 with support from the George B. Storer Foundation, the Center is housed in and integrated with Prescott College’s Department of Education and Teacher Preparation.
The Center focuses on designing innovative nature and place focused professional development opportunities and course curricula for undergraduate and graduate programs. It offers residential professional development institutes and outreach workshops that provide training and experiential learning opportunities for early childhood educators across Arizona and beyond, including the Summer Institute for Nature and Place-Based Early Childhood Education. Learn more at: www.prescott.edu/sifece
The Center provides opportunities and support for student research on the effectiveness of nature and place-based early childhood teacher education and outdoor learning activities in order to add to current professional knowledge in the field. The center actively seeks opportunities to collaborate with other higher education institutions, schools, and organizations in implementing nature and place-based teacher training initiatives and related research projects.
Nature Play Learning offers design consultations, professional development, and project management services to help you maximize the potential of nature play landscapes from concept to installation to pedagogy and use. A design consultation with NaturePlayLearning will begin your site’s journey toward a sustainable, safe, and sensory-filled naturescape perfect for connecting any age to nature. As your process of transformation is underway, I offer professional development and front line delivery appropriate for all levels of stakeholders from the kids themselves to the staff to the administrators and funders. Presentations and workshops can include any aspect of nature play design, planning and use. I will work with you to decide what will directly meet your site’s and your audiences’ needs.
The McDowell Sonoran Conservancy is a non-profit organization that champions the sustainability of the largest urban preserve in North America. More than 30,500 protected acres, known as Scottsdale’s McDowell Sonoran Preserve, are enjoyed by 750,000 hikers, mountain bikers and equestrian riders each year. As stewards, we connect the community to the Preserve through education, research, advocacy, partnerships and respectful access. McDowell Sonoran Conservancy offers programs for grade school, high school, higher education, citizen science and more.
