Lids On! Teaching Children Survival Skills

Children are excellent at picking new information however children often find learning survival skills difficult. Even when they do remember what to do to survive, will they remember to use the skill when they need it?
Educating children for wilderness survival needs to be very simple and driven home with a demonstration. Take for example the simple skill of having and wearing a warm hat. Exposure to the elements is something that is very dangerous. It can be fatal to adults and children are even more sensitive.
This may seem like a simple thing, wearing a hat is definitely a simple thing but have you ever tried to keep a hat on a child under ten years old? This is an almost impossible task, except when NOT wearing a hat is too painful like in extreme hot or cold temperatures. Waiting until it is too painful before you put on a hat might be too late in a survival situation.
Here is an experiment you can do with kids to show them the importance of keeping insulated. It is called the Lids On experiment.

What you will need is very simple and you may already have them in your house.
1) Two pots of equal size with lids.
2) Two thermometers. It can be done with one thermometer but it is more dramatic with two. More drama increases the likelihood of them remembering the lesson.
3) Stove with two equal sized burners
4) A timing device, watch, stopwatch, egg timer or a normal clock will all be
sufficient.
5) A measuring cup.

The procedure for the lids on experiment is very simple as well. And there are many possibilities for side lessons some of which I will point out.

1) Measure out the same volume of water and pour it into each pot.
2) Bring both pots to a boil at the same time.
3) Turn off heat source for both pots at the same time.
4) Measure the temperature of the water and note the time.
5) Leave the water to cool on the stove. But leave one pot with it’s lid on and one pot without a lid. You can do the entire experiment again and leave the pots outside and watch the temperature drop faster.
6) Have the kids guess which will cool faster, lid on or lid off?
7) After approximately 10 minutes return and measure the temperature of both pots.

The pot without the lid will be significantly cooler. This is because the lid traps warm air around the top of the boiling water. (Just like a hat does for our heads). The water not protected by the insulating effect of the air is exposed to the elements and heat is actively lost very rapidly. (Just like our body heat when we are improperly protected from the elements).

This experiment can be more than a survival lesson. You can expose children to the safety precautions around the stove/cooking, the physical properties of water (why it boils and at what temperature), how to tell time or read a clock, how to measure volume/temperature and how to ask a scientific question (hypothesis) and test for an answer.
I would only add more information about the experiment if the child or children are really demonstrating that the survival lesson has been learned and internalized. Saying the phrase “lids on” after the experiment has been completed when the child is putting on a hat will help drive the message home. So will playing a Simon Says type game where the commands are Lids On and Lids Off. Lids On instructs that they put on a hat and act warm. Lids Off instructs that they take off the hat and act cold.
The repetition after the experiment will be the best thing you can do to maximize the chances that they will remember to put their lids on when they really need to.

Rebuilding Society: Agriculture

This is my latest article on what is important for rebuilding society after a societal collapse. Agriculture is important for obvious reasons. Without an adequate food supply there is no possibility for any society. Agriculture is the only long term method for managing the food supply. Hunting and gathering take too much time and area for current populations. Storing food is very temporary and doesn’t last very long. Trading for food is something many countries do today, but this is dependent on a very reliable transportation network.

The lowest level of sustainable agriculture is subsistence agriculture. This means the levels of production from agriculture are just enough to sustain your own existence (or your family’s existence). Subsistence agriculture is very time intensive. It leaves you with little to no time for other things like education, construction and any other form of employment. Societies heavy with subsistence agriculture are also societies rampant with poverty. Subsistence farming is not a way to grow a society, it is merely a way to survive. After a societal collapse, subsistence farming will become common place. Those with knowledge and the means to grow food will probably be able to produce ample amounts of food. It is everyone else who will struggle to achieve a subsistence level of food production. Those that fail will probably die from starvation.

The knowledge required for successful agricultural production needs to survive the collapse. Books on the subject are a good start. A much greater resource are people who are already successful at propagation of food plants and raising livestock. Agriculture at any level is more complicated that putting seeds in the ground or letting a herd roam free. There will be local conditions that determine best chances of success. Soil and weather patterns vary widely at surprisingly small scales. If someone you know has knowledge like this, make them your new best friend.

Historic techniques for farming will be very useful. Many modern crops and farms are dependent on pesticides and fertilizer. Unless someone knows how to continue making these chemicals, those supplies will quickly run out and in some cases expire. Ideally, the knowledge required is more than just historical farming techniques as many of them were destructive to either the environment at large, water sources and soil quality. The best knowledge to have are the low technology techniques for treating current agriculture problems. A good example of what I mean is how flies around cattle can spread pink eye around the herd. Currently this is usually controlled by a bovine insect repellent sprayed over the cattle. It works great at keeping flies away, but after the collapse the industry and transportation infrastructure may not be present or reliable. A low technology solution is to feed the cattle garlic. Something in the garlic makes the cattle less appetizing. You may not notice less flies around the herd as you would with the insecticide, but the infection rates of pink eye will go down, and isn’t that the problem that needed solving? With the prevalence of garlic worldwide, this solution for pink eye cold be done by almost any cattle farmer (I’m not sure if garlic would affect milk taste in a dairy cow). My point is, all the farmer needs is to grow some garlic and he/she has something with multiple uses and is dependent on nobody to do it.

After subsistence level agriculture, comes increasing levels of food security, wealth and time. Historically we moved beyond subsistence farming by improving techniques and creating new techniques, new hybrid crops and breeding animals to better suit local conditions. This was achieved through research, experimentation and trial and error. After a collapse, research and experimentation will probably stop, leaving just trial and error and people who know better slowly spreading the best techniques through word of mouth.

As society begins to reform, places with food will become boom towns and places without will disappear. Sustainable agriculture is the best way towards a stable society.

Can I use a storm-water pond as a back-up source of water?

Storm-water ponds are the closest alternative source of water for many people living in urban areas. In an emergency this source of water may be all that is available to you.  Eventually any water you have stored will be consumed and the water in a storm-water pond may be the difference between life and death.  With the proper treatment your local storm-water pond can be a great backup source of drinking water.

Storm-water presents a unique set of challenges during treatment. Because storm-water ponds collect surface water, the water is exposed to all the contaminants on the ground in the catchment area. This includes but is not limited to pesticides and fertilizers applied to lawns, motor oil and gasoline leaking from vehicles and litter like cigarette buts. It all ends up is the storm-water pond. Those chemicals are already in storm-water ponds on a normal day. During an emergency there may be additional contamination from sewage runoff from an overloaded or broken sewage system. The water in the pond will also contain all the microorganisms like ecoli, giardia and cryptosporidium normally in surface water. Any one of these will make you very sick if you get infected with them.
Finally, there will be high levels of nitrates in storm-water ponds. Too much nitrates consumed by young children can cause blue baby syndrome.

The first step in treating water from a storm-water pond is straining. Straining the water through a cloth or loose sand filter will remove large particles (ones you could pick up with your fingers). Remove as much of the suspended particles from the water as you can. Straining the water first will extend the life of your proper water filter.

If you have a clarifying agent like aluminum sulfate, this is the best time to add it to the water.  It will make contaminants too small to be filtered become attracted to each other and become significantly larger.  Larger particles are easier to remove from the water. Let the water sit still for at least 30 minutes without disturbing it.  All the newly formed large particles (called floc) will sink to the bottom.  When you take the water from this container, make sure you leave the majority of the settled material at the bottom of the container.

The next step is to filter the water. Filter the water even if it looks clear, the human eye is five times too weak to detect dangerous levels of particles. Filter the water at least once through an activated carbon filter. Activated carbon is known to remove many different chemicals from water including pesticides, chlorine and fluoride. Activated carbon is not the same as charcoal. Charcoal is similar, it can remove toxins from water but it is nowhere near the efficiency of activated carbon.

The third step is oxidation. Oxidation will help with disinfection as most disinfectant chemicals are also oxidizers. Chemicals like sodium hypochlorite and potassium permanganate are both oxidizers and disinfectants. Oxidation will break down many of the remaining contaminants and inactivate many of the remaining bacteria. Keep adding the oxidizer/disinfectant till you can detect a residual after 20 minutes. The 20 minutes is the minimum you should wait for a gallon of water. Wait longer for larger volumes. This is because oxidation is a chemical reaction that isn’t instant. It needs time to complete the reaction.

The fourth step is to filter the water again. Filtering again is necessary because the disinfection/oxidation step will create some potentially carcinogenic byproducts. We filter before oxidation to minimize the amount of chlorine (or other chemical) and to limit the possibility of forming dangerous byproducts. We filter the second time to remove any byproducts that have been formed.

The final step is to boil the water.  This will help with disinfection, but the main goal of boiling at this point is to remove any volatile chemicals.  Any chemical with a boiling point lower than water will be removed after boiling.

A note about disinfection.  If all of these steps are followed there is no need for a step dedicated for disinfection.  Between the oxidation and the boiling of the water any microorganisms will be inactivated.  If you are storing the water for a long time then add some sodium hypochlorite for a residual disinfectant.  The residual disinfectant will prevent the water from becoming recontaminated before you drink it.

One additional possible step is to aerate the water.  Ponds are frequently stagnant.  Stagnant water is green with algae, it smells bad and tastes worse. After the water is made potable, transfer the water back and forth between two glasses. This adds oxygen to the water and will make the water taste better.

This may seem like a lot of work for something as small as a storm-water pond.  What I have described are the basic steps to turn the potentially toxic water in the pond into clean and safe drinking water.

Water Preparedness: Common Beginner Mistakes

Are you thinking about starting to store water? How about emergency water treatment? Getting started can be a very daunting task. Where should efforts be focused? What pitfalls should be avoided?  This article will explore a few of the mistakes I see people make when they start to take their personal water security seriously

Don’t be left without potable water. Avoid beginner mistakes. (source: always foodie.com)

The very first thing to learn is that there is no magic bullet. There is never a single product or technique which will always make water safe to drink. Combining, knowledge, multiple storage/treatment techniques and multiple products for storage/treatment is the best way to guarantee a safe source of drinking water for yourself and your family.  This logic or philosophy of combining as many protections as possible is used by municipal water systems all across North America.  It is referred to as a multi-barrier approach and it boils down to having many different protective measures to prevent contamination, in the event that one barrier fails, there are still many others in place.  To put it in layman’s terms, when it comes to water security, it isn’t a good idea to put all your eggs in one basket.

Marketing campaigns will make all sorts of claims about water products. Some will be irrelevant, like claims of BPA free plastic when the product is made from a type of plastic that never had BPA. Other claims will be over stated. The claim that is most often overstated is the number of times a water treatment product can be used. The quality of the water being treated is too variable for any company to give you an absolute number of times. This might not be done to deceive you. It could just be that the water they tested the product with was easier to treat then your water. Remember that no product will make the water perfect.  They will make the water safer when used correctly, if used incorrectly many water treatment products can make the water significantly more dangerous to drink.

Water needs to be stored in an appropriate container. This container needs to be able to physically hold the weight of the water and not leach any chemicals into the water. Assuming any garbage can sized container is appropriate will at best lead to soggy disappointment and at worst a severe case of gastrointestinal disease. For more information on water storage, read The Why? How? and How Much? of Water Storage?

Once your water is stored it needs to be kept safe. Water can become contaminated at any time. Anytime the container is open there is potential for contamination to occur. Read this article to find out what to do when your backup source of water becomes contaminated. The assumption that water only needs to be treated once is false. What was once safe to drink may be very dangerous when you need it if your aren’t protective of your supply. Water can turn stagnant when stored for long periods of time. Stagnation while not a health hazard is a taste hazard. Stagnant water tastes bad. Adding air to the water is how you relieve stagnation. Adding air is as simple as passing the water from one glass to another repeatedly or stirring the reservoir. The goal is to increase surface contact between the atmosphere and the water. It is important that aeration of the water will also remove the remaining chlorine (if any was present) in the water. If you are aerating the reservoir make sure you add some more disinfectant. Do this so you can keep your disinfectant residual high enough to keep the water contamination free.

Another mistake people make, is they store water but make no changes for reducing the water they use. Forgetting to change behavior during a crisis is probably the biggest mistake beginners make. Different situations require different behavior, this applies to your personal water use. You will be amazed at how much water is used if you aren’t careful. What could last a week might be used in a day and then you will understand the true value of water conservation. This mistake can also happen in more than just your water use.  For more information on water conservation read why water conservation is a prepper’s must do.

The single biggest mistake beginners is they assume that they can learn how to treat water later. Later becomes too late and then it can become fatal. It is very difficult to learn something complicated like water treatment when your life depends on it. Learning as much as you can before an emergency strikes is the single best thing you can do to stay safe.

This article covers just a few of the common mistakes I see people make when they start taking their water security more seriously.  There are many more mistakes that can be made and no one person has the perfect solution to them all. Water security is something that needs to be tailored to each person or family’s needs.  Have you found any common mistakes while preparing for water shortages? If so, leave a comment below, I would love to hear them.
