I love the fall! The colors start changing and the leaves begin to cover the yard. Kids go back to school, family gather for holidays, and a light, crisp chill hits the air reminding me to enjoy the season before winter comes to erase the year away.
But the biggest reason I love fall is for all the bountiful fruits and veggies that abound! Fresh produce is one of things I enjoy about living in rural Colorado.
You don't have to go very far to find a veggie stand with zucchini, squash, vine ripened tomatoes, and lettuce. Or just take a short drive east and you'll find a sign for "You Pick..." apples, peaches, pears, apricots, berries, etc....
But the thing about fresh is - fresh isn't fresh forever! Sad Day...
Thankfully my folks were both avid food preservationists and instilled in me the knowledge to preserve fresh food for my own family. Thus was born my passion for canning! A passion I happily can pass on to the youth I work with!
Life Skills Girls Learn to Can Applesauce!
This last week I joined the Life Skills girls group again to teach them about food preservation. We discussed the difference between fresh food and preserved food and why preserving food now allows for long term storage later.
After all, who doesn't want to crack open a can of homemade applesauce in January, when apples are scare in Colorado?
Applesauce is pretty simple to make and can at home, and has a shelf life of about 1+ years. We took our recipe from the National Center for Home Food Preservation website (see direct recipe link below) because it's important when canning to always use an Approved (Tested) Recipe from a reputable source.
NOTE: label above for display only and does NOT indicate an approved recipe! The science behind canning has to due with heat treatment (or heat/pressure treatment if using a pressure caner). Everything you place inside a jar for canning must be heated fully to a certain temperature and then held at that temperature for a determine length of time. This high heat for X amount of time is what preserves the food and kills off any illness causing bacteria that might be present. Approved recipes have been tested to meet the heat/time requirements needed to keep the food you are preserving safe! Always can with an approved and up to date recipe! Back to applesauce! The girls helped skin, core, and slice the apples and then cooked them up into a big batch. Applesauce can be made smoother by running it through a food mill, but since I don't have one presently (Christmas Present???), we opted for chunky applesauce from the blender!
The girls were each able to fill a pint jar with the sauce and place it in the water bath caner. Apples have a lower pH which also helps to kill off any tag a long bacteria still in the product. Processing takes time and we have to add additional time to make altitude adjustments (Most recipes are for sea level to 1000ft - We are canning at 4,875ft). Going up in altitude means we have to wait a few more minutes for things to cook, no problem!
Unless you have a bunch of applesauce hungry girls on your hands, then waiting is FOREVER!!!! So they do dishes to pass the time.
All Done! We opened an extra jar and poured it out. We like to add some zing to applesauce in our family so we melted in some Hot Tamale candies and everyone enjoyed! HINT: For a tasty treat, try dipping corn chips into your applesauce!
Food preservation can help you enjoy the fruits of the summer, no matter what season. For these girls, hopefully they will see how saving the bounty of food now to eat it later can help them provide for their families one day too!

Apollo 17 - Return Landing Many a youth has been asked the probing question "What would you like to be when you grow up?" Although there were many answers (i.e. Vet, Police, Fireman, Doctor...) one that always put a smile on my face was when a little called out ASTRONUT! Yes, even some of us adults still ponder what it would be like to have climbed NASA's stairs to the capsule, entered the control module, and waited to hear the countdown for takeoff and a chance to see the stars, moon, and earth from a completely new angle! Although very few of us have ever had (or will have) the opportunity to do a space walk, for a youth interested in STEM Careers, the space program (past and future) has created numerous avenues for creative and innovative career pathways that are STEM approved and still give space seekers a chance to 'Shoot for the Stars" with their career pathway. History of the Command Module Parachutes! Parachutes were first imagined in the 14th century....
Simple Sugar Glucose This month, I got to teach a class on cellular respiration, or how cells make energy. Cellular respiration is the process of breaking down sugars into ATP (Adenosine triphosphate), what we call energy. Cells can use Aerobic or Anaerobic pathways for breaking down sugars into energy. Aerobic means 'with oxygen' while Anaerobic means 'without/lacking oxygen'. Although a cell can use both pathways to produce energy, the efficiency of ATP production is greatly affected in a non-oxygen environment compared to when oxygen is present for the process. For comparison, a single glucose (sugar) molecule will produce only 2 ATP in the fast paced and wasteful anaerobic process, while the aerobic process can produce 34-38 ATP from the same, single sugar molecule. The complicated process of how a cell makes energy Our class experimented with yeast to see how the process works in real time. We couldn't, of course, see the cellula...
Welcome back to school! Yes, some of you have been at your desks since August already, but time flies as you get older (Trust me....). It's exciting to see that STEM is taking a front row seat in our districts' this year as each school has brought on a STEM coordinator to bring the joy of hands on education through Science, Technology, Engineering, and Mathematics! I'm going to be brief today but want to share just a couple of fun resources available through our STEM Programming this year! Three (3) In-Classroom/Home Chicken Incubators available for loan out to study life cycles/sciences. These kits include all the materials needed to go from a fertilized egg to the live chicks and engages students in discussions about the industry, parts of the egg and cycles, creating a farm, and even life and death conversations and dissection's. 25+ STEM Kits for Check-out through our kit loan program. Like a backpack program, STEM kits can be checked out ...
