Experiment 1: Materials: • Alka-Seltzer tablets • Empty and clean water or soda bottles (12 oz to 24 oz) • Balloons • Water • Clock • Stove top Procedure: 1. Pour a sufficient amount of water (about 16 oz) into a small pot and place on the stove at high heat. 2. Watch the clock and after 30 seconds take the water off the heat.
Our dependant variable in this experiment was the dissolved oxygen parts per million in each sample. We recorded this data on the white board back in our classroom, writing down the specific parts per million that we found in the water. The variables that were the same for all

The methods used in this lab experiment consisted of having four different drinking categories. These categories were non-drinkers, Coke, Gatorade, and water; the subjects will be chosen randomly to drink one of the drinks and then void 30 minutes after. After voiding, the subjects will have measured their urine temperature, urine volume, calculate specific density, urine pH and urine flow rate. After the calculations are done, the subjects will use the Labstix strips to measure if their urine tests positive or negative for blood, ketones, glucose, and protein. In my hypothesis I will expect water to have the greatest urine volume and flow rate, then all other drinks (Gatorade, Coke, and non-drinkers).
In this experiment, the hypothesis of having planaria to grow with the living conditions of Powerade or Gatorade was not supported. When going through and reading the statics all the planaria died with each experiment that I decided to do. I decided to put 10 drops and 20 drops of Powerade into a petri dish with 10 planaria in each petri dish along with 40 mL of spring water. With the results given it appeared that it was too much Powerade so, I decided to reduce the amount of dosage given with Powerade and only give them 1 drop in each petri dish.

Mika Nijhawan 9/29- 10/10 2 MENTOS AND SODA LAB REPORT State the Problem Does the type of soda affect the size of the explosion, after mentos are added? Develop a Hypothesis If seven mentos to a 2L bottle of Diet Pepsi, then it will create the biggest geyser out of Coke, Fanta, & Root Beer because Diet Pepsi has potassium benzoate, aspartame, and the carbonation which react to mentos. Design an Experiment Materials List: 1 clear test tube 35 original flavored Mentos candies (2 1/2 rolls) 1 3x5 index card 4 2L bottles of soda (all different flavors/types) 1 2L bottle of soda water 1 100 mL graduated cylinder 1 400 mL beaker 1 pair of tweezers (preferably large) 1 small container Procedure: Stack seven mentos in the test tube When given permission take the test tube, soda bottles, index cards, and the remaining 25 mentos, to the designated area Place one of the four soda bottles on a flat area Open the soda bottle and place the 3x5 index card over it With the index card over the soda bottle, flip the test tube over and place it on the index card, so the test tube is lined with
Five hundred years ago, European explores landed in North America. After trying to locate a new route to Asia across the Atlantic Ocean, they found a continent they did not know existed. Three different groups traveled to the New World, starting in 1584 (Basu, Tanya). The last group included Governor John White, whom had to return to England to submit his report to the Queen. John White tried several times to return to Virginia, it wasn’t until a few years later he was finally able to returned to his new home.
Introduction: In this lab, of water in a hydrate, or a substance whose crystalline structure is bound to water molecules by weak bonds, is determined by heating up a small sample of it. By heating, the water of hydration, or bound water, is removed, leaving only what is called an anhydrous compound. Based on the percent water in the hydrate, it can be classified as one of three types: BaCl2O ⋅ 2H20, with a percent water of about 14.57%, CuSO4
