Materials and Methods:
Independent Variable- Length of the rubber band.
Dependent Variable- Rate of stretch when weight is added.
• Same person measures rate of change- Avoids any miscalculations from other persons.
• Same washer size- Different size washers could tamper with the weight and rate of stretch.
• Stationary ring stand- By having the ring stand taped to the table, avoids the ring stand from shifting and avoiding faulty calculations.
• Unused rubber bands- If a stretched rubber band is used, it could alter the rate of stretch.
• All materials are quality controlled.
• Different size rubber bands are the same material.
• Rubber bands are unstretched and unused.
1. One 7.62 cm x 0.3175 cm rubber band
2. One 8.89 cm x 0.3175 cm rubber band
3. One 17.78 cm x 0.3175 cm rubber band
4. Four paper clips
5. Dixie Cup
6. Ring Stand
7. Meter Stick
8. 20 Same Size Washers
9. Scotch Tape
1. With a hole puncher, make two holes in the cup. One on each side. Clip three paper clips together, with the two end paper clips through the holes. This makes an accurate weight basket.
2. Attach a paper clip to the ring stand, tape with 5 cm piece of tape to reinforce paper clip. Put 7.62 cm x 0.31745 cm rubber band on the paper clip.
3. Attach basket to the rubber band on the ring stand.
4. Position the ring stand so it hangs over the table. Attach meter stick to the table, and make sure the meter stick flush with the rubber band,
5. Add two washers and wait until there is no movement with the basket. Then record the date and the units. Repeat steps until all washers are used (ten total data points).
6. Repeat with the next two sized rubber bands.
It was hypothesized that the stretch of the rubber band when weight is added is effected by the original length of the rubber band.

Effect of Leaching Treatment on Mechanical Properties of Natural Rubber Latex (NRL) Products Filled Modified With Kaolin
- Introduction Natural rubber latex or commonly abbreviated as NRL is a liquid milky sap which was tapped from Hevea brasiliensis, trees which were originally from region of South America. It has rubber content of 33% which was suspended in 65% of water and contained 2% of protein. NRL is chemically known as 1,4-cis-polyisoprene. Production of NRL has grown rapidly and its main used was as manufacturing of gloves . In order to improve mechanical properties of these products, several studies had been done using silica, calcium carbonate, montmorillonite (MMT), kaolin as fillers to reinforce vulcanizates [2-5]....

- Synthetic and Natural Rubber Abstract Rubber is an important resource with a wide variety of applications. It can be obtained naturally from the rubber tree, Hevea brasiliensis. It can also be synthesized from petroleum and natural gas. Both natural and synthetic rubbers have their own advantages and disadvantages. Natural rubber is made up the linear chain polymer, cis-l,4-polyisoprene. Styrene-butadiene rubber (SBR) is the most common synthetic rubber. It is a random copolymer of styrene and butadiene and has good physical properties once it has been strengthened through vulcanization.... [tags: Comparison Material Rubber]

- Rubber Tires: Rubber Tires play crucial role in enabling better performance for the vehicles. These are important parts in automobiles, trucks, buses, aircrafts, tractors, industrial machines, shopping carts, bicycles, motorbikes and baby carriages. There are many applications of rubber tires and over the years the demand for this product has been increasing since many new vehicles are launched every day and also there are many number of vehicles which are already in use. Tires are the only point of contact of the vehicles on the road and the intentions of the driver who is driving the vehicles.... [tags: Tire, Tires, Wheel, Synthetic rubber]

- Polytetrafluroethylene, previously listed above, can be used here again for utensil coatings and electric insulators, just as polystyrene may be utilized for insulating materials. For interior and automotive design, polyvinyl acetate is used in adhesives and latex paints. Fiber products such as indoor-outdoor carpeting, textiles, car and truck parts, packaging, and toys can all be made from polypropylene. Other commercial applications of chain-growth polymers include break resistant containers (polyethylene), glass substitutes (polymethyl methacrylate), synthetic rubber (isoprene rubber), and CDs/DVDsPolymethyl methacrylate, or Plexiglas and Lucite are very popular glass substitutes for obj...

- “We live in a toxic environment where we are almost guaranteed to get sick.” Morgan Spurlock states in the documentary Super Size Me. One possible cause of our sickness is in part due to what we consume. Americans have become adapted to a fast paced lifestyle that effected was the way we eat. Which eventually led to Americans becoming accustomed to eating unhealthy fast food. Corporations saw this growing culture and took advantage of this in order to make a profit. Eventually they began to completely disregard the consumer 's health in order to keep making their money.... [tags: McDonald's, Super Size Me, Fast food restaurant]

- Preface In this research I am going to investigate the effects of class size on student achievement. The debate over class size is an age-old debate in American education. The debate concentrates on whether class size is factor that could affect student performance. Currently, many moved to very large or small classes. As a student I am interested to see how the class size might affect my academic performance. The research has been contacted on March 1, 2015. I am using five sources, 3 peer reviewed journal articles, 1 newspaper article, and 1 magazine article.... [tags: Education, Higher education, University, Gymnasium]

- In recent years, many researchers have carried out a series of studies aiming at the MEPCM. Alkan et al. [ ] prepared a series of MEPCM with polymethylmethacrylate (PMMA) shell and characterized their properties. Wang et al. [ ] prepared the paraffin/PMMA MEPCM by polymerization catalyzed by UV light. In order to further study the effect of preparation methods on the size of microcapsule, Wang et al. [ ] prepared a variety of MEPCM with PMMA shell and analyzed the effects of various factors on the size of microcapsule.... [tags: Heat, Heat transfer, Temperature]

- Body image disturbance is a core feature of anorexia nervosa. Often people who suffer from anorexia refuse to eat more than is absolutely necessary to maintain a minimal weight for their height. Øverås, M., Kapstad, H., Brunborg, C., Landrø, N. I., and Lask, B. (2014) experiment analyzed body size estimation on perception and memory, in patients with anorexia nervosa by comparing results with a healthy control group. They had a particular interest on how anxiety may have influence on anorexia nervosa patient’s perception of their body image.... [tags: body image, anorexia, body size]

- As Steven Spielberg once said, "documentaries are the greatest way to educate an entire generation" (Azevedo, 2013). In Morgan Spurlock's documentary Super Size Me, audiences are informed and shown the dangers of consuming fast food everyday. Spurlock has a camera follow him for one month as he consumes McDonalds for each meal thus exposing one to the unhealthy affects of the lifestyle. Relying on images, interviews, and statistics the viewers are informed of how processed fast foods begin to affect people starting from a young age.... [tags: Film Analysis, Super Size Me]

- The Effect of Light on the Size of Ivy Leaves Aim --- Design an experiment to investigate if light affects the size of Ivy leaves Plan ---- In this experiment I will explore how light affects the size of Ivy leaves. I will use the common Ivy called Hedera helix. I will take two stems of Ivy, one from the part of the garden that is exposed to lots of light, and one which exposed to little light. The Ivy leaves that are facing the south of the garden will have been exposed to high light intensities, whereas the leaves facing the North of the garden will have been exposed to low light intensities....
