Science Will Save the World! Episode 3: We’ve Got Chemistry! (Acid and Base Experiment) with Jessie Rack

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…)

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

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 ( Interested in learning more about sky islands or about conserving these amazing places? Check out Sky Island Alliance (

Nature Play Learning (Statewide)

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.


McDowell Sonoran Conservancy (Scottsdale)

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.

NEEF | Environmental Literacy Report 2015

Environmental educators have an unprecedented opportunity to create a more environmentally literate citizenry — a citizenry equipped with the knowledge, skills, and motivation to tackle the environmental, social, and economic challenges that we face today and in the future.

USA National Phenology Network and Nature’s Notebook Citizen Science Program

Observing phenology, or plant and animal life cycle events, through Nature’s Notebook citizen science program from the USA National Phenology Network offers place-based, hands-on learning opportunities, provides a collaborative platform for site-based educators, and promotes cross-subject engagement while addressing standards of learning.  Their formal and non-formal education resources can be used to help students of all ages plug into real-world scientific research questions addressed by many researchers, natural resource, land manager and educational groups. Phenology is an excellent lens for teaching about the natural world.

Laboratory of Tree-Ring Research (Tucson)

The primary mission of the Laboratory of Tree-Ring Research is to remain in the forefront of world dendrochronology through the use of tree rings as natural chronometers and recorders of change in the environment with which human society is inescapably linked. The Laboratory makes significant contributions to understanding natural environmental variability in climatic, hydrologic, geomorphic, and ecological systems.

They are committed to promoting public awareness (and understanding) of science and making informal contributions to science education. As part of their Outreach program, they strive to inspire new connections and nurture existing connections among our community, which includes visitors to and residents of Tucson, and the K-12 educators and students communities.

AZ Dept. of Environmental Quality (ADEQ) | Children’s Environmental Health (Statewide)

The Arizona Department of Environmental Quality (ADEQ) is sponsoring a new recognition program to help individual schools become Arizona Environmentally Healthy (AEH) schools. This program recognizes policies and actions taken by schools to help ensure a healthy and safe learning and teaching environment. This checklist is to be used by school principals, or their designees, to certify to ADEQ that the school has taken action to safeguard their students, faculty, and other personnel against environmental pollutants and other potential environmental risks.

Green Education Foundation (GEF)

Green Education Foundation (GEF) is a national non-profit organization committed to creating a sustainable future through education. GEF aims to identify key factors and impediments influencing sustainability education, evaluate existing approaches, and develop effective educational materials and programs to promote behavior change towards sustainable practices.  GEF offers free programs that provide curricula and hands-on activities to inspire K-12 students and teachers to think holistically about global sustainability concerns and solutions.
