Background of the Study!

• Hot and cold therapy is one of the best methods to relieve any kind of pains.

• Historically, heat has been a natural remedy used both to relieve pain and enhance the recovery process. By increasing the temperature of the skin surface and underlying tissues, heat stimulates the thermo receptors – sensory receptors that respond to heat and cold – which then help block transmissions of pain signals to the brain. This translates into a significant decrease of discomfort.

Objectives

• The general objective of the study is to give information to others on how a heat can be stored and produced; to give information about the characteristic of Sodium Acetate and how it store heat. The objective of this project is to make our own heating pad to be able to save money.

Significance:

• The super cooling phenomenon intrigued us because of its ability to store heat for long periods of time and release it when desired. And importantly, this research will educate the people in promoting business in the community. Lastly, this project can be very convenient for those people who always experience pain due to the different daily activities that they exercise.

Observation• When the researchers poured the vinegar in

the baking soda the solution started to make bubbles.

• A chemical reaction took place while are doing the said experiment. The researchers have knowledge this because a gas was created. We know a gas was created because foam was formed as soon as you added the baking soda and vinegar together. We also know that a chemical reaction happened because a solid was formed after the solution was heated.

• The researchers also observed that while we are mixing the vinegar and baking soda, the solution began to react and crystallization already took place.

Enhancement• Since our group observed that the

crystallization of the main product has not been completed. The researchers decided that in our second try in doing our experiment; we will make sure that we will add more baking soda and vinegar so that the process will be completed.

ALTERNATIVE RESOURCES

• Natron(alternative for baking soda)• Natron is a naturally occurring mixture of

sodium carbonate decahydrate (Na2CO3·10H2O, a kind of soda ash) and about 17% sodium bicarbonate (also called nahcolite or baking soda, NaHCO3) along with small quantities of sodium chloride and sodium sulfate. Natron is white to colourless when pure, varying to gray or yellow with impurities. Natron deposits are sometimes found in saline lake beds which arose in arid environments. Throughout history natron has had many practical applications which continue in the wide range of modern uses of its constituent mineral components.

• In modern mineralogy the term natron has come to mean only the sodium carbonate decahydrate (hydrated soda ash) which makes up most of the historical salt.(Wikipedia,2010)

Summary• After finishing a series of experiments, the

researchers therefore conclude that vinegar and baking soda are very effective substitutes for home made hot and cold packs. The researchers also learned that our project is as effective as the commercialized packs that can be bought from the leading drugstores in our country. In connection with our research, this project can help mostly of our fellowmen that is in the field of construction and agriculture who doesn’t have enough money to buy fast remedies for their muscle pains and injuries.

Insights• The researchers learned that using

vinegar and baking soda as a substitute to the usual materials that is used in making hot/cold packs can be very effective in a way that there is no change in its quality and effectiveness. The researcher’s also learned that the product that we adapted is a very helpful remedy for most of the people that is in the field of sports and recreation because they don’t have to buy the expensive not-so-effective commercial product to cure their injuries.

Recommendation• The following are the recommendation that

you can do with the project:• The product can surely help the Filipino

household. You can use the product in terms of home based purpose; it can serve as a part of your first aid kit.

• It can also be used as a quick remedy for tooth ache and head aches.

• The researchers highly recommend this as for medical purpose only.

• The researchers also recommend this product to be sold in a very low price since the materials used in this project is very much cheaper than the usual sodium acetate.
