step in the actual experiment is to open the two packages containing the polymer creatures and then placing each of them aside for later. Next‚ fill the the two containers with the two different liquids of choice‚ which in this case is water and vinegar. Finally‚ after filling the containers‚ place one of the two polymer creatures in each of the containers. Also‚ be sure to record the results throughout the day as the creatures soak in each liquid and to observe all of the effects that each liquid

Pickling is the process of preserving food by anaerobic fermentation in brine or vinegar. The resulting food is called a pickle. This procedure gives the food a salty or sour taste. In South Asia‚ edible oils are used as the pickling medium with vinegar.[1] Another distinguishing characteristic is a pH less than 4.6‚[2] which is sufficient to kill most bacteria. Pickling can preserve perishable foods for months. Antimicrobial herbs and spices‚ such as mustard seed‚ garlic‚ cinnamon or cloves‚ are

also releases gases. An exothermic reaction is a reaction that releases energy as heat. Since the energy is released‚ the exothermic reactions feel hot. Methods/Materials I did three experiments. I mixed lemon juice and baking soda‚ammonia and vinegar‚ and finally‚ hydrochloric acid and sodium hydroxide. I did each experiment when the acid was 0‚ 20‚ 40‚ 60‚ and 80;all in degrees Celsius. Therefore‚ I could compare the exothermic reaction with the endothermic reaction at each temperature.
