what it has come to. Therefore‚ the government needs to impose a soda tax. The soda tax debate has garnered big headlines in newspapers. It ’s only fitting that the attention surrounding America ’s obesity epidemic might come to rest on sugar-sweetened beverages (SSBs.) The nation ’s penchant for soft drinks is on the rise; we now drink on average 50 gallons per person per year‚ about double the amount we drank in 1977.

Experiment #1: Introduction to Experimentation Submitted by: Neann Klara M. De Jesus BS Psychology II Submitted to: Dr. Geraldine E. Tria ABSTRACT SUMMARY The first experiment done by the class was called “Introduction to Experimentation”. Its main objective is to give basic knowledge about some of the logic of experimentation. The class was divided into groups of 2. In each group there was an experimenter (E) and a subject (S). The experimenter instructed

fastest way to cool a soda deals a lot with heat transfer. Heat is a measure of the average molecular motion of matter and can be transferred from one piece of matter to another in four different ways which are conduction‚ convection‚ evaporation‚ and radiation. (Tania Dakka) In the experiment the different levels of the independent variable include a cooler with ice‚ another with ice and water‚ one with water ice and salt‚ the refrigerator‚ and the freezer. Prior research has been done on this

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

doing “What is the fastest ways to cool soda?”. I believe‚ that the salted ice water bath will be the most effective one and cool the sodas the fastest. The salted ice bath with water can lower the temperature of the soda to 44 degrees in 5 minutes. There are several ways that I could cool soda. Some of the most popular methods to cool are in a salted ice bath with water‚ ice bath no water‚ and the freezer. I will be testing these ways with different types of soda each time with 3 trials.

Here are some eco-friendly ways to get rid of mold. Baking soda offers amazing results Baking soda is one of the most popular eco-friendly ways to get rid of mold. You can either use it mixed with water or vinegar. Spray it onto surfaces and leave it sit for about a day. Then scrub it and wipe it using a damp cloth. The results

Our objective for the Sherlock Holmes Experiment was to illustrate that some chemicals can be identified or differentiated by simple chemical tests‚ such as solubility‚ pH‚ or color tests. In our group we had to test come common powders such as Alka-Seltzer‚ baking soda‚ flour‚ Vitamin C (ascorbic acid)‚ and salt. Other chemicals that were used to do this experiment were vinegar‚ and Iodine 2 Solution. The equipment used to do this experiment was red litmus paper‚ and 5 test tubes per group. After
