A large variety of scissors and shears all exist for specialized purposes. Hair-cutting shearsand kitchen shears are functionally equivalent to scissors, but the larger implements tend to be called shears. Hair-cutting shears have specific blade angles ideal for cutting hair. Using the incorrect scissors to cut hair will result in increased damage or split ends, or both, by breaking the hair. Kitchen shears, also known as kitchen scissors, are for cutting and trimming foods such as meats.Modern scissors are often designed ergonomically with composite thermoplastic and rubber handle s which enable the user to exert either a power grip or a precision grip.https://en.wikipedia.org/wiki/Scissors

Thread
Thread is made from a wide variety of materials. If your machine will sew with the thread, any thread can used for just about any purpose. This is very useful for someone who is trying to learn sewing. However, it should be remembered that where a thread is stronger than the material that it is being used to join, if seams are placed under strain the material may tear before the thread breaks.
Garments are usually sewn with threads of lesser strength than the fabric so that if stressed the seam will break before the garment. Heavy goods that must withstand considerable stresses such as upholstery, car seating, tarpaulins, tents, and saddlery require very strong threads. Attempting repairs with light weight thread will usually result in rapid failure, though again, using a thread that is stronger than the material being sewn can end up causing rips in that material before the thread itself gives way.https://en.wikipedia.org/wiki/Thread_(yarn)

Ruler A ruler, sometimes called a rule or line gauge, is an instrument used in geometry, technical drawing, printing, engineering and building to measure distances or to rule straight lines. The ruler is a straightedge which may also contain calibrated lines to measure distances.[1]

Scissors
Scissors are hand-operated shearing tools. They consist of a pair of metal blades pivoted so that the sharpened edges slide against each other when the handles (bows) opposite to the pivot are closed. Scissors are used for cutting various thin materials, such as paper,cardboard, metal foil, cloth, rope, and wire. https://en.wikipedia.org/wiki/Scissors

Round nose pliers
Round nose pliers, rosary pliers or snub-nose pliers are a specialized plier characterized by their rounded, tapering jaws and most commonly used for creating loops in pieces of wire by electricians and jewellers.[1]
Some round nose pliers have insulated handles for safeelectrical work, a spring-fitted joint and comfortable grips on the handles.https://en.wikipedia.org/wiki/Round-nose_pliers

Clear Nail Polish
You can use clear nail polish to prevent the conductive thread from fraying.

A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode, which emits light when activated.[4]When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.

Conductive Thread
A conductive textile is a fabric which can conduct electricity. Conductive textiles can be made with metal strands woven into the construction of the textile. There is also an interest in semiconducting textiles, made by impregnating normal textiles with carbon- or metal-based powders.[1]
Conductive fibers consist of a non-conductive or less conductive substrate, which is then either coated or embedded with electrically conductive elements, often carbon, nickel,copper, gold, silver, or titanium. Substrates typically include cotton, polyester, nylon, and stainless steel to high performance fibers such as aramids and PBO. Straddling the worlds of textiles and wires, conductive fibers are sold either by weight or length, and measured in denier or AWG.
Because of the rapid growth in the kinds of conductive fibers and the uses of these fibers, a trade association--the Conductive Fiber Manufacturers Council[2]--was formed to increase awareness, utilization, and possibly standardize terminology. https://en.wikipedia.org/wiki/Conductive_textile

Hand needle
A sewing needle for hand-sewing is a long slender tool with a pointed tip at one end and a hole or eye at the other. The earliest needles were made of bone or wood; modern ones are manufactured from high carbon steel wire and are nickel- or 18K gold-plated for corrosion resistance. The highest quality embroidery needles are plated with two-thirds platinum and one-third titanium alloy.https://en.wikipedia.org/wiki/Sewing_needle

Coin Cell Battery
A watch battery or button cell is a small single cell battery shaped as a squat cylinder typically 5 to 25 mm in diameter and 1 to 6 mm high—like a button on a garment, hence the name. Button cells are used to power small portable electronicsdevices such as wrist watches, pocket calculators, artificial cardiac pacemakers, implantable cardiac defibrillators, and hearing aids.
Devices using button cells are usually designed to use a cell giving a long service life, typically well over a year in continuous use in a wristwatch. Most button cells have low self-discharge and hold their charge for a long time if not used
A metal can forms the bottom body and positive terminal of the cell. The insulated top cap is the negative terminal.https://en.wikipedia.org/wiki/Button_cell Angela DeHart, 5/2016
Battery Holder A battery holder is one or more
compartments or chambers for holding a battery.https://en.wikipedia.org/wiki/Battery_holder

Prepare for Step 2: What tools do I need to explain why I choose my design?
Angela DeHart, 5/2016
Step 2: Choose the design you want to make. Explain why you choose that design.
I complete this design because it allows me to demonstrate many sewing techniques. 1. I can sew on the sewing machine when I sew on the earth 2. I can hand sew when I put on the buttons 3. I can show off my ability to cut when I cut the windows for the space ship 4. I think it shows off my personality because I have always interested in space 5. I think the design is creative because it puts all of these technical elements together and makes them look nice 6. This will be a nice keepsake for my time in this class 7. It will look good when I hang it in my room. I can’t wait to see it when I cut the lights in my room off and leave the LEDs in my spaceship on!

Prepare for Step 3: What tools do I need to make each component of my design?
Angela DeHart, 5/2016
Step 3: Determine how each component of your design is going to actually be made.
a. Determine how many buttons I need and can affordb. Choose “STAR” buttons from lab’s button collection c. Pay Ms. DeHart for the buttons (write a check)d. Determine where the buttons go, estimate how long it is going to take me to sew them on and then and sew them on my design
a. Find a photo of earth I want to useb. Determine how large my earth needs to be to work with my designc. Purchase a sheet of fabric print paperd. Print the picture, estimate how long it is going to take for me to process and sew the earth on, and then sew the earth on my design
a. Determine the number of colors and types of fabric I will need to create my designb. Create a pattern for each component of my rocket that I need to cut it out of a different color fabricc. Purchase the fabric from Ms. DeHartd. Cut out my patterns. Pin and cut the parts out of my fabrics and then sew my rocket onto my design
a. Determine where your LEDs are going to be in your designb. Determine where your battery holder is going to be in your designc. Draw an electrical schematic of the circuit you are going to sew to make your LEDs light upd. Purchase the LEDs, battery, battery holder, any other electrical components you need for your design from Ms. DeHarte. Create your circuit Angela DeHart, 5/2016
Step 4: Create your designs based on the information and supplies you gathered in Step #3
Step 5: Turn your work in for grading
IF there is time left in the semester: a. Is there anything you can redo & turn in to improve your grade? b. Verify with Ms. DeHart that you are authorized to help other students, and help c. Look at completing the extra credit project d. Help clean the room for the end of the semester/year Angela DeHart, 5/2016

Appendix A: Polarity (That means there is a positive (+) and negative (-) side to each component.)
Battery Holder• Positive (+, "E"): The positive end of the battery holder looks like an
"E" shape.
• Negative (-, with slot): The negative end of the battery holder has a slot.
Battery • Positive (+): The top side of the battery has
writing on it.
• Negative (-): The bottom side of the battery is blank.
LED • Positive (+): The positive leg of the LED is
longer.
• Negative (-): The negative leg of the LED is shorter.

Appendix A: Polarity
To test the LED and battery: 1. Touch the LED positive leg to the battery positive side.
IF the LED and the battery are “good” the LED will light up!
Problem solving: IF the LED does not light up: a) Check to see if the battery good? b) Check to see if the LED good? c) Check to see if you have the (+) part of the battery & the LED touching?
(That means there is a positive (+) and negative (-) side to each component.)
