Thermometer Procedure: Fill the three beaker with water. - Beaker #1 will be filled with ice cold water (4c). - Beaker #2 will be filled with water at a room temperature (20c). - Beaker #3 will be filled with hot water (75c). Place a magnetic stirrer in each beaker.
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.
For this I needed to first obtain deionized water. I cleaned my large graduated cylinder and got 20 + or - 2 mL of deionized water. I then added this water to the beaker that contained the mixture I created from the last step of the experiment. I also gathered 2 boiling stones and added them to the mixture of the last step. I placed the beaker on a hot plate and heated it up to 130 degrees Celsius.
The scientists will conduct the experiment by taking four cups of water one that is just salt mixed with water, another that is just water, a third cup that is just ice water and finally a forth cup that is vinegar and water mixed. After that the scientists will drop one Alka-Seltzer tablet into each cup and see how long it takes for it to completely dissolve. The scientists will conduct these three times for
Investigative Question: Which temperature does a bath bomb dissolve in the fastest, 120°F, 100°F, 80°F, or 60°F? Purpose The real life application of the experiment is so people will know the optimal temperature to use when using a bath bomb for the most effervescence. Hypothesis: If a bath bomb is put in 120°F water, then it will dissolve the fastest, because
We started by putting 100 mL of water into a coffee cup calorimeter (a polystyrene cup inside another polystyrene cup as an insulator), a magnetic stir bar was added and using the program LabProTM the
When the gummy bear was placed in roughly 40 mL of water for an estimated three days, it dissolved. The results did not support the hypothesis written, as due to the gummy bear dissolving before measurements took place, it could not be concluded for certain
The purpose of this lab was to determine whether sugar can dissolve in certain solvents. We observed the dissolving rate of 2g of sugar in 50 mL of water, 50 mL of rubbing alcohol, and 50 mL of vegetable oil. It was hypothesized that if the sugar was put in water, it would dissolve faster than if it was put in rubbing alcohol. It was observed that the sugar dissolved in water, but did not in rubbing alcohol or vegetable oil. Therefore, the hypothesis was correct.
First, they collected the materials, then they poured water into each cup in even amounts, next they poured 1/8 of sugar in one, then they poured 1/8 of salt into another. They left one cup with just regular water and sat them in the freezer. They regularly checked to see which one froze the fastest. The sugar water ended up freezing first, before the plain and salt water. The plain water froze second, and in the last place was the salt water.
In this experiment the scientist will be testing different liquids to see if all liquids evaporate at the same rate. The scientist will have water, orange juice, nail polish remover, Coke, a small cooking pot, and a stove. The scientist will boil all of the liquids and measure which liquids evaporated the fastest. The science behind evaporation is when all of the molecules are rapidly in motion. Liquids evaporate due to heat, which makes the molecules in a liquid to move faster.
Being, if hot and cold water were combined, then the cold water would move beneath the hot water because cold water is denser than hot water. Methods Materials: - Small glass bowl - Ice - Cold water - Food coloring - Spoon - Clear glass cup - Hot water - Clear medicine dropper Procedure: 1. First, in the glass bowl, mix the ice, cold water, and food coloring with the spoon 2. Next, fill the glass cup with hot water 3.
For this lab I will be using water and sucrose to demonstrate the rate of osmosis. In this lab I will be exploring how temperature impacts the rate of osmosis by placing pieces of potato of equal size in solutions of different temperatures and observing the change in mass of potato after a given period of time. The change in mass will indicate the rate of osmosis.
The hypothesis that me and Edgar came up with was that one sugar cube was that the sugar cube after being continually shaken in a glass mason jar for 3 minutes would have become a fine sugar powder. After seeing how the first experiment went we assumed that two sugar cubes after being shaken for 3 minutes would make 3 balls of sugar ,and we hypothesized that the 3 sugar cubes after being shake for 3 minutes would make 5 small sugar balls. After shaking the sugar cube we emptied the jar to find two balls of sugar one much smaller than the other and we also found sugar powder. After we shook up the other sugar cubes the size and amount of sugar balls increased , but strangely enough the amount of powder increased as well with the amount of sugar
The experiment began by gathering the materials. The materials consisted of a ring stand, test tube clamp, 600 mL beaker, 10 cm watch glass, Vernier temperature probe, alcohol thermometer, 11 dram vial, cork with a slit cut in side, spatula, powder funnel, rubber band, 20 cm wire, top-loading balance, analytical
Materials 1 calibrated thermometer, 1 scale that reads mass, 2 Styrofoam cups, 1 small lead sinker, boiling water in a beaker, 1 pair of kitchen tongs, 1 small cooking pot, stove top, distilled water, and 1 pair of safety goggles (I did not use a cork stopper). III. Procedure First, the beaker
