EA #43.0 Mountain Survival Situation
Your charter flight to your annual fly in fishing trip to Canada has just crash landed in some low foot hills below the timberline of the Rockies. The crash site is in a very remote and rugged area. The ten passenger Otter sea plane started to burn when it crashed, however all ten passengers survived the crash with minor injuries; unfortunately the pilot was killed in the crash. Only a few metal pieces of the frame remain after the fire. It is approximately noon in mid-January during a severe winter storm.
The Problem:
Before the plane caught on fire, your group was able to salvage some of their gear. The list below is the gear that was salvaged. Your group has the task of ranking in order the items salvaged in order of the importance to the groups survival. Use the number one to represent the most important, two the second most important and so on. In fifteen minutes we will discuss your and the rest of the classes rankings so be prepared to validate your prioritization.
Items salvaged
A metal coffee pot
A liter of Vodka
Four wool blankets
A Jack knife
Sectional map of the pilots
A flashlight with four batteries
One pair of Cross-Country skis
A 9’ x 12’ plastic sheet
Three books of matches

EA #43.5 The Desert Survival Situation
It is approximately 10:00 AM in mid July, and you have just crash landed in the Sonora Desert in southwestern USA. The light twin engine plane containing the bodies of the pilot and the co-pilot has completely burned. Only the air frame remains. None of the rest of you has been injured seriously.
The pilot was unable to notify anyone of your position before the crash; however, ground sightings, taken before you crashed, indicated that you are 65 miles off the course that was filed in your pre-flight plan. The pilot has indicated before you crashed that the plane was approximately 70 miles south-southwest from a mining camp which is the nearest known habitation.
The immediate area is quite flat and, except for occasional barrel and saguaros cacti, the area seems to be rather barren. The last weather report indicated that the temperature would reach 1100, which means that the temperature within a foot of the surface will hit 1300. You are dressed in light-weight clothing- short sleeved shirts, pants, socks, and street shoes. Everyone has a handkerchief. You have collectively in your pockets $2.83 in change, $85.00 in bills, a pack of cigarettes, and a ballpoint pen.
Before the plane caught fire, your group was able to salvage the 15 items listed below. Your task is to rank these items according to their importance to your survival, starting with #1 being the most important and #15 being the least important. First rate the items individually and next discuss your lists with your group and rate them as a group, your group must come to consensus (where everyone agrees to agree on the list).
Items salvaged
Flashlight with batteries
Jack knife
Sectional air map
Plastic raincoat
Magnetic compass
First aid kit
Loaded pistol
Red and white parachute
Bottle of salt tablets
1 liter of water per person
A book titled, Edible Animals of the Desert
Sunglasses enough for everyone
2 liters of Vodka
1 coat for each person

EA #47.0 Survival Food Gathering
The last thing that you need to be concerned about in a survival situation is food. The average person, according to the “rule of threes”, can go about 3 weeks without food. The average person lost in the wilderness is found within three days, so the lack of food should not effect your survival. If, however, you are unlucky enough to be one of those people that are not rescued within a few weeks you will need to gather food as our ancestors did in the wilderness.
To educate ourselves on the topic of gathering food in the wilderness we will be gathering information from a website. Remember we learned how to gather non poisonous foods by watching animals browse and also we learned the hard way what was poisonous and what was not, so do not experiment on your own with wilderness gathering only gather foods that you are certain are nonpoisonous.
The website you can visit is the following (or do your own search), http://www.wilderness-survival-skills.com/survivalfood.html.
Even though you will not need food for three weeks to survive, why is food important in all survival situations?
What determines the food sources you will be able to exploit?
Why should you make sure that you vary your diet? What provides everything a long term survivor would need?
What is the most appropriate diet in the early stages of a survival situation?

Look in Eating Wild Plants, What are the two rules to remember in identifying poisonous plants?
What is the last step of the edibility test? What happens if you are unlucky and pick the wrong plant?
What are insects rich in, why do we not eat them?
Look in Survival Foods, where do you look for insects and bugs to eat?
What are some examples of useful insects to eat?
Look in Simple Methods of Catching Fish, What can you use as a float to catch fish? For a hook? For bait?
Where can you find fish if the weather is hot? If the weather is cool? Where do fish like to get shelter?
When is the best time to catch fish? What is the technique for spearing fish? How could you improvise a landing net?
How should you obtain your meat in a survival situation?
Look in Simple Traps, Why is it crucial to regularly check traps? What type of prey should you attempt to trap?
How can you determine the presence of animals? What should you look for where you may use your traps or snares?
How can you avoid leaving signs of your presence?
Look in Dead Fall Traps, sketch a figure four dead fall trap. Sketch the variation to the figure four trigger.
What can be used to make snares? Sketch a snare. How high and wide should the snare be?
Why are eggs a good food source?

E.A. #56.0 Plans for a Five Day Pack
In this activity you will be making plans for a two day expedition into the wilderness. You first must decide what type of expedition you will be taking part in and then the supplies that you will need to take along on your expedition.
First stage of planning is to decide where you are going into the wilderness and what type of physical activity will be involved. You then must calculate your calorie requirements for the expedition and plan a menu that will provide the calories in a well balanced fashion. The National Outdoor Leadership Schools diet plan recommends that you supply 3,700 Calories each day for summer expeditions and 4,250 Calories for winter expeditions.
How to determine your energy requirements:
Your basal metabolism is the number of calories that you require just to stay alive without any physical activity. Just staying alive for the 5 days is your first activity in the chart below.
Basal Metabolism = (0.45 Calories) X (#hours during your trip) X (#pounds you weigh)
Calories to supply energy for your activities.
Activity Cal *hr*lb
Walking @ 2mph 0.45
Walking @ 3 mph 0.90
Walking @ 4 mph 1.60
Sitting 0.20
Sawing wood 2.60
Camp duties 0.60
Swimming 3.60
Driving 0.40
Canoeing 2.00
Climbing 3.00 (Add 1.10 Calories for each lb for 1000 ft rise)
Biking 2.40
Fill in the table with each activity you will plan on doing for the five days. Find the calories burned in the table above for each hour and pound you weigh. Multiply the three columns together to get the calories burned for each activity. Finally added up the calories for each activity to determine the total calories you will need to consume to supply your energy requirements for all your activities.
Activity Calories/hr?lb Your Weight Hrs of Activity Calories
Discussion
How does the total of calories you calculated in 3 compare to that recommended above.
To supply the most calories in the smallest weight for you to carry what types of food should you consume?
E.A. #57.0 Energy (Calories) Input
To power your human machine on your outdoor adventure you need to stoke your furnace with fuel. That fuel comes in the form of the foods you will be eating and that you will be packing for your trip. To ensure that you will have enough food to supply your energy needs we will be planning menus in this activity for a trip of five days into the BWCAW. You will use your caloric needs that you calculated in E.A. #56.0 and the reference materials in the EA Resource Manual pages 300 through 319.

Engine Management System
There are cities with populations of millions in Asia and Europe where people do not own cars. They use mass transit or bicycles. Could we in Rochester use principally mass transit or bicycles to commute daily? Discuss why you answered the way you did.
EA #63.0 Bicycle Maintenance
Before we go on our bicycle tour in a couple of days you will need to check over your bicycle and make sure it is safe to ride. Remember you are only as safe and as comfortable on your ride as your equipment will allow.
In this activity you will practice on the bicycles provided and then perform the same safety check on you bicycle at home.
Pick up your bike and shake it. Investigate any rattles, this any other noises the bike makes while riding is how your bicycle communicates problems to you.
Check the brake blocks for excessive wear.
Brake blocks adjusted so they have maximum contact with the rim when they are engaged.
Brake blocks should not contact the rubber of the tire.
The brake levers should only move two inches, if they move any more the cables will need to be adjusted.
Check brake cables and shifter cables for fraying, both at the hand controls and the mechanisms.
Go through all the bolts and nuts and make sure they are tightened.
Check to see that the wheels do not wobble on the bearings.
Make sure that the seat is tight and does not tilt or rotate when struck with your heel of your hand.
Handle bars and goose neck are tight when wiggled up and down and side to side.
There should not be any play in the pedals when you wiggle the crank around.
The pedals should be tightly screwed to the crank.
Look for cracks in the frame, especially in the joints of the frame.
Make sure that the nuts or quick release levers good and tight.
Check the tires for wear, cracks and proper pressure. Tires can require anywhere from 40 to 100 lbs of pressure. Spot check by pressing the tire on the curb, you should be able to hit the curb and not pinch the tire to the rim.
Are the valve stems straight and without cracks, do they have their dust caps?
Make sure the seat post has at least two inches inside of the frame; most have a safety mark on them.
Check for presence of reflectors or lights on the front and rear of the bicycle.
Adjusting a derailleur:
Have someone support your bicycle so that the rear wheel is off the ground. Turn the crank and pedals slowly and shift through all the gears on the right (rear) gear select lever. If the derailleur does not slide the chain through all the gears then it needs to be adjusted and cleaned. First remove all of the old oil and dirt from the gears and derailleur and re-oil the gears, you should not use regular oil on your bicycle it attracts dirt, use a silicon lubricant. Use the two adjustment screws, one for the smallest gear one for the largest, to ensure the derailleur reaches the two outside gears but do not over adjust causing the chain to jump off the gears.
EA #64.0 Bicycle Fitting
You should be able to identify and measure certain aspects of your bicycle so that you are familiar with its construction and design. Use one of the bicycles provided or your own to answer the following questions.
Brand name and model of your bicycle.
Serial number.
Frame size (measured from seat post to crank).
Wheel size.
Tire size and pressure.
Age of the bicycle.
How many speeds (number of front gears times number of back gears).
Material frame is made from (Steel, Aluminum, Chrome alloy, Titanium, Carbon fiber)
Weight of the bicycle.
Quick release hubs or nuts.
Calculate the gear ratios.
Divide the number of teeth on the rear gears into the number of teeth on the front gear and multiply that number by the diameter of the rear wheel.
Check the fit of your bicycle by standing over the bicycle. The cross bar should be no less than 1” below your crotch.
Adjust your seat height so that your knee will have a slight flex in it when the ball of your foot rests on the pedal. A seat that is too high or low will cause sore knees.
It is important to have a clean chain, derailleur and gears to keep them from wearing out. A thin coat of bicycle lubricant (do not use regular oil it attracts dirt) will ensure that the parts do not rust and move smoothly.
Obtain some mineral spirits and take a clean cloth and wipe the chain, front gears, rear gears and derailleur to ensure that they are very wet. Allow the mineral spirits to dissolve the old grease for a few minutes.
Next take an old tooth brush and dip it into the mineral spirits and brush the chain, gears and derailleur until they are clean.
Finally coat the gears, chain and derailleur with the bicycle oil.
Check the pressure of the tires using a tire pressure gauge, make sure the gauge reads pressures to the pressure required as indicated on the side wall of the tire. Release air from your tires if necessary by using the button on the back of the tire gauge. Add air to your tire only using a compressor designed for tires and toys. Using an automotive compressor fills the tires to quickly and could lead to rupturing the tires.
Wash and wax your bicycle regularly to stop the formation of rust and make it look nice.
Helpful Hints:
Try to not use of the smallest diameter rear gear it causes excessive chain and gear wear.
Do not pedal your bicycle backwards, especially when shifting. It will ruin your derailleur.
Shift before coming to a hill. When shifting reduce your pedal pressure, this will reduce wear and having the chain jump.
Use your arms and legs as shock absorbers to reduce stress on your frame and wheels.
Remember that wet rims do not stop as efficiently as dry rims.
Try to keep your weight back on your bicycle.
Do not use your front brake solely it will cause you to flip over the handle bars.
Always wear shoes when bicycling, no open toes or flip flops or sandals. Your toes can be cut off in the spokes.
Remember people driving cars are not looking for bicyclists; they are looking for cars, so make sure they see you before making a move around them.

EA #73.0 Quarry Hill Fossil Hunt
The sedimentary rock formations that have been uncovered in the quarrying operations at Quarry Hill Park are loaded with fossils. These sedimentary rock layers like the Decorah Shale and the Dubuque Limestone where deposited in shallow seas 400 million years ago, during the Ordovician Period. You will be looking for small corrals, worm borrows, Trilobites , Brachiopods, and Crinoids, for a few examples. Use the Identification Key provided by your teacher to help identify the fossils that you find.
A good place to hunt is on the ledge in the quarry or on the cliff above the caves. Find at least six different fossils, put them in plastic collection bags and fill out the specimen sheet and place it in the bag with the specimen.
Cut out the six specimen sheets below and place them in your collection bag with your fossil finds.
