Lesson 116

For a first aid kit you will need something to stop a lot of bleeding: non-adhering dressing or bandages, surgipad, surgical dressings, medical tape. Telfa bandages for smaller wounds. Having something to adequately stop bleeding while you wait for help may save someone’s life.
Supplies to clean wound(s): 5 ml test tubes for hydrogen peroxide. Alcohol swabs.
Supplies for repairing a wound if you are out in the wilderness: single-edge razor or scalpel. Medical sutures.
Any medications that you need (label bag). Cotton balls. Band aids for minor cuts and scraps. Transparent plastic kit bag to fit all first aid supplies.

Lesson 117

Three signs of heat exhaustion are dizziness, headache and fever. Three signs of heat stroke are unconsciousness, blurred vision and rapid shallow breathes. Three signs of hypothermia are cold, pale and low body temperature. The primary steps to treating heat stroke are calling 911, cooling the patient down and comforting them. The primary steps to treating hypothermia are warming the patient up and calling 911.

Lesson 118

The difference between a second-degree and a third-degree burn is a third degree burn makes the skin chalky and white and a second degree burn is just blisters and maybe redness. You treat a first-degree burn by cooling it down. You treat a second-degree burn by cooling it down, putting it under the sink for 10-15 minutes and if it is bad enough call 911. You treat a third-degree burn by cooling it down, calling 911, putting it under the sink for 10-15 minutes and rapping it in plastic rap. Three ways to prevent burns from occurring in your home are be careful, have protecting gear on and have supervision. Higher sunscreen SPF not sufficient for protecting your skin because it doesn’t get any better than SPF 50.

Lesson 119

If there is a fire in your house roll out of bed onto floor; don’t stand up if there is smoke or flames in the room. Feel door with the back of your hand to make sure that it is not hot. If door is hot or if you see flames do not open the door Crawl out of your house or building.

Essay 2 First Aid

For a conscious choking adult and child you would put the thumb side of your hand over the bellybutton but below the ribs and rotate your hand as you move your hand up and in. For a conscious choking baby you would turn the baby over on your knee and support the head and give 5 hard back slaps then 5 chest compressions look in the mouth to see if there is the object if so sweep out and if not repeat until food gets out of the mouth.

The way to help someone who is unconscious and choking is just doing CPR but look into their mouth before giving the rescue breath and sweeping out the object if you see it but if you don’t see the object give a rescue breath and if that doesn’t go in then reposition the head and try again if it doesn’t go in repeat this cycle until you can see the object and sweep it out when it does come out continue with CPR.until help arrives or until the patient wakes up.

Some common side affects of shock are decreased level of conscious, angsty, chilled and cold, pale and clammy, rapid breathing or pulse and low capillary refill. To treat shock, elevate the legs at the knee then cover the patient up or keep them warm some other way. Every few moments check for responsiveness by shouting and tapping

To help bleeding wrap a tight bandage and start the furthest from the heart and wrap towards it. You don’t take the bandage off you only add to it. To properly wash your hands you should use germ-x unless you have physical stains on your hands then you wash your hand for 60 seconds at least with warm water and soap.

Science (Fitness)

In this unit I will be talking about “All the things that you probably do wrong every day.”

The first lesson is about sleep. Getting enough sleep is important why but too much sleep is bad. An average teen needs 8-11 hours of sleep and an adult needs around 7-10 hours of sleep. It depends on your age.

As you all know, water is important, but how important? Studies show that in order to get enough water you divide your weight in half and that is how much water you should drink in ounces. Did you know that when you exhale you are releasing water particles. Your body is around 75% water.

Sitting for long periods of time actually is bad for your health. I know, I know sitting can be great to catch your breath from a sport or an exercise. In the end excessive sitting is bad, if you do have to sit, sit with your knees and feet at a 90 degree angle and with your back straight.

On the 1% chance that a druggie is reading this DONT DO DRUGS. Sugar (although fatting) is an alternative for drugs. Something that drugs and sugar have in common is dopamine (pleasure). But sugar never fades away. With drugs you can’t get that full sensation anymore well with sugar you always do it doesn’t level out. DONT DO DRUGS OR SUGAR but if you are a druggie do sugar instead.

Do you live with stress? If you do it is very bad for you. It can cause inflammation and diseases. What stress does is it destroys connections in the brain and that can be dangerous. It can later have a big negative impact on later life. Cure: meditation, exercise.

Smoking is a terrible thing to do. It destroys lungs and lives. It can cause cancer and other terrible things. The best cure is to stop smoking. Second hand smoking is bad Because the smoke that comes out from the end still has chemicals in it so it is just like some one else smoking with you. Side note: STOP SMOKING.

Pain killers are killers. Number one; they can be addicting and two; if you overdose you can DIE. There are other ways to cancel out pain like herbs and stuff like that. If you do your research you’ll know what herbs to buy to numb the pain.

Do you play video games? If so you know how important controllers are. Without them you couldn’t play. Same thing with enzymes. Enzymes are the remote controller for your body. Foods like veggies are loaded with them. What they do is DESTROY bad cells.

Kale, carrots, broccoli, dark leafy greens-what do these all have in common? VEGGIES! Kale actually has more and better calcium than milk. The milk excuse doesn’t work any more. Carrots actually help you see in the dark. Broccoli is just good for you.

Sprouts are great and better for you than store-bought veggies or fruits. one reason is the nutrients are lost in store bought vegetables and can not be gained back. Another reason is it could have chemicals that make it look but not be good for you

To pick a sprout you can’t just get any one. You have to do research and thinking. Alfalfa and sesame seeds are great, so are beans, and other things. Different sprouts do different things just do some research before you start.

I started my sprouting project today and I just soaked them. Tonight they will be soaked enough to rinse and do all of that stuff. I planted quinoa, it is black, white and brownish.

Bees are very important. They make honey which has healing properties and its yummy. Wild honey is better for you because it doesn’t have pesticides. Also it is made from a wide variety of wild flowers which gives it natural nutrition.

Exercise is more important than you would think. To exercise start with stretching in 5 second bursts, be careful and don’t go past the point of pain. You need a 12 week exercise program with intense and easy workouts.

Emotional health is important. Are you an optimist or a pessimist? This is a question you should ask yourself. Pessimists tend to get depression more than optimists. So start looking for the light pessimists.

Manners are important. You might think you know them all but you would be wrong. Do you know the proper dining set up? Use your manners daily because they make an impression, good or bad. People are watching.

Hygiene is being clean and being prepared. Think about it, you need to know what you are wearing the next day. Is it clean or dirty? Ask yourself the tremendous three. What will I wear? Is it clean and prepared? Am I clean and prepared?

Now that you know health&fitness, fight, for the right, to liiiiiiiiive in HEALTH!

 

 

Science lessons 21-24

Lesson 21 is the crystal radio project. A crystal radio is a radio that needs no electricity. Lesson 22 is the amplifier project. Lesson 23 is the AM transmitter project. The transmitter is so simple to build. Lesson 24 is the yagi antenna protect and it too is simple.

Lesson 21

Radio project; build the radio

If you would like to build a crystal radio there are multiple youtube videos that take you step by step though the instructions on how to build a crystal radio. My advice to you is invest in one because if you are a teacher or a mom or even a kid, they are great and inexpensive.

Lesson 22

Radio project; build an amplifier

Amplifiers are electronic components that amplifie a current or wave. An example of an amplifier is a speaker. Amplifiers are interesting because they are everywhere in your earbuds, in your phone, and in your speaker. They are in pretty much everything.

For an amplifier (speaker) you need Two 10 microfarad (uF) electrolytic capacitors, One 0.1 microfarad (uF)ceramic capacitor, Two 220 microfarad (uF) electrolytic capacitors, One 0.047 microfarad (uF) ceramic capacitor, One 10 kilo ohm potentiometer (variable resistor), One 10 ohm resistor, Simple on/off switch, One 9 volt battery ,Battery circuit attachment, Small speaker (8 ohms works), One LM386 amplifier chip or equivalent part, Amplifier chip socket, Perfboard, Solder and soldering iron and a Plastic jar. For instructions watch this video. For an amplifier for the earpeice you will need One 0.001 microfarad (MF or uF) capacitor, Two 1 microfarad (MF or uF) capacitors, One 10 microfarad (MF or uF) capacitor, One 82 kilo ohm resistor (82k), One 100 kilo ohm resistor (100k), One 10 mega ohm resistor (82M), One 2N4401 transistor or equivalent part, One 9 volt battery, Breadboard (for testing) and watch this video.

Lesson 23

Radio project; build an AM transmitter

To build an AM transmitter you need One small transformer (audio or doorbell transformer), One oscillator chip(for AM radio frequencies – 540 kHz to 1.6 MHz), Sound source (CD player, iPod, etc.), One mini male phone-jack (1/8″ works), Four AA batteries, Battery holder case (4 AA slots), Breadboard, 24 gauge (AWG) wire or22 gauge also works. For the video it is here https://youtu.be/_4-Sx-T6VBc

The transmitter works by turning AC(alternating current) to DC(direct current) because AM frequency are AC but the radio needs DC to play sound. I think that is funny because if it can convert AC to DC, then why can’t it just accept AC?

Lesson 24

Yagi and dish antennas

The dish works like a funnel with a filter it picks up all of the stations and then funnels them out. The yagi works with music wire and the music wire is the thing that pick up the stations and the radio filters them out. Antennas have to be half the length of the wavelength ex: 3 meter wave length 1.5 meter antenna. The gain of an antenna is a very technical measurement but, broadly speaking, boils down to the amount by which it boosts the signal. Bandwidth is the range of frequencies it can pick up. If you are interested in the yagi antenna (I am) you can build one with this video and some cheap supplies it is very interesting and I highly advise making one.

All and all crystal radios and some extra components are cheap and inexpensive. They are fun to build and they teach lots of great stuff. Some things are worth spending money on and this is one of them.

Science lesson 31-34

Lesson 31 is the first robotics lesson because it is the start of a new unit. Robotics is the science of designing and building robots. They are awesome because they do dangerous things that people can’t. The other 3 lessons (32-34) are talking about robotics

Lesson 31
Robotics intro
In this lesson you will learn how robotics can boost your skills by electronics, mechanics, work shop, team work and programming. A robot is a device that does not need a mimics animal or human behavior and does not need a human controller and artificial intelligences is a field that people are trying to mimic human intelligence.

lesson 32
Robotics project overview
The robotics project will start in 15 lessons we will be building the RRB-bot platform.The project is in 2 parts the first and the second. For the project (if you want to build it) you can find parts here and here. Kits are great but expensive around $200+ they save time and maybe money you might want to look into the project because it is super cool. The website we will be using is robitoid.com.

lesson 33
Robotic bot families
The main 6 categories are stationery vs. mobile, autonomous vs. teleoperated, self contained vs tethered. There is this awesome arm on the hubble space telescope that can lift 7000lbs. in space but can’t lift itself on earth. Speaking of cool electronics there is this invention that is called the walking truck that is powered by hydraulics and it is very tiering because when you move it makes it move.

lesson 34
The origin of the word robot comes from roboti which means hard labor. To make a universal gripper you watch this video here but the supplies you need are a air hose, balloon, funnel, and coffee grounds

All and all we learned about the intro to robotics, the project that i will be doing, bot families and robotic anatomy.

Science lessons 16-19

In science lessons 16-19 we learned a lot about electronics and crystal radios. Lesson 16 was on soldering. Lesson 17 was on Arduino. Lesson 18 was on electronic test equipment. Lesson 19 was on how a crystal radio works.

In lesson 16 we learned that welding is melting metal together and letting it dry, soldering is melting metal off of wire to make an electric connection. The tools you will need are here and a wire that needs fixing.

In lesson 17 we learned about Arduino. Arduino is a tool that allows you to “play” with technology. Arduino is super cool in fact a group of people made a critter cam to take a picture when movement is sensed. To get Arduino click here to get the safe software click here

In lesson 18 we talked about electric test equipment. An oscilloscope is a device that measures an electric signal. A multimeter measures ohms, volts, amps and watts. The multimeter is better than something like an ohmmeter that only measures ohms.

In lesson 19 we talked about how crystal radios work. A crystal radio is complex. First  radio waves travel through the antenna down to one coil which gives off a magnetic wave which hits another coil, the tuning coil. The tuning coil has a tuning slide which can slide to tune. Close to the tuner is a capacitor that is connected to a diode then goes through an ear piece. finally it goes up and around to earth ground like this

 

Science Lessons 11-14

This blog post is dedicated to lessons 11-14. Eleven is on semiconductors and diodes.Twelve is on transistors. Thirteen is on integrated circuit. Fourteen is on schematics diagrams.

In lesson 11 we learned what a diode does, what a semiconductor does and why a diode is needed for a crystal radio. A diode is an electric device that allows current to flow in only one direction. A semiconductor is an element that is usually an insulator but is turned into a conductor with the proper amount of volts. A diode is important for a crystal radio because regular waves are alternating and a crystal radio needs direct current and a diode can do that.

In lesson 12 we learned the primary benefits of a transistor and what the electrical contact for the positive and negative junction of a transistor is called. One of the benefits of a transistor is a transistor turns a circuit on and off like 35000 times a minute. The positive junction is called the gate the negative is the source and the drain.

In lesson 13 we learned what an integrated circuit is and what it is made of. An integrated circuit is a set of circuits on one small semiconductor material. A integrated circuit is manly composed of silicon.

There are multiple links for schematic symbols here is one. Schematic diagram are used to help build electronics because instead of drawing each component they can just draw the symbols.

In conclusion building electronic components is hard.
