A possible error that could have been made was not doing at least three experiments. If more experiments were done, the information would have been more accurate. Another possible error was only using two liquids. If more than two liquids were used in this experiment, then the information would have also been more accurate. A major error in this experiment was using a different starting temperature for each trial.…
As well, I noticed that once a pill bug wandered into the colder chamber, they would tend to stay. One thing we could do to further improve the experiment is to add more pill bugs to the chamber, in order to help prove the test's reliability.…
All data and observations were recorded in the lab notebook. Pages from the lab notebook are attached to the lab. Results…
We thought if the light was dim in a single chamber, the pill bug would go to that chamber. In this experiment, there are two variables: the independent and dependent. The independent variable, the one that is manipulated, is the lighting. In this case, there are four different degrees of lighting: light, barely dark, medium dark, and very dark.…
In conclusion, in this lab, we are trying to find how different beak types influence the amount of seeds they collect and how different seed types influence the amount of seeds the beak collects. My hypothesize is that the largest beak (binder clip) will collect the most amount of seeds because there would be more space. The data doesn’t support/support my hypothesis since the relationship between the variables is inconclusive. For instance, the data shows that the clothespin “beak” from the insula maxima region and the binder clip “beak” from the insula minima region collected the most amount of seeds in their respective regions. Since the most number of seeds isn’t from one specific “beak”, my hypothesis is inconclusive.…
The question I investigated is if organisms are more attracted to a strawberry then nothing. My hypothesis was "If one cup has a raspberry and the other doesn't" Then The cup with the raspberry will catch more organisms because They want to eat the raspberry so they go into trap number 2. " My hypothesis was correct because I caught ten more organisms the the one with out a lure. After all this research I could come to the conclusion that organisms like raspberry compared to nothing at all. Some evidence from my expire ment that supports the conclusion is that the raspberry caught about 10 organisms while the empty one caught only 1.…
The goal of the experiment was to determine how the rate of photosynthesis responded to the amount of light wattage the plant was exposed to. My groups hypothesis was that an increase in light wattage would cause an increase in the rate of photosynthesis. The independent variable of this experiment was the amount of light wattage the spinach chards were exposed to. The dependent variable of this experiment, or the variable that changed in response to the independent variable, was the rate of photosynthesis experienced by the chards. We measured this variable by observing the amount of spinach chards floating in water and baking soda.…
The purpose of this experiment was to find the affect of salt on the temperature of boiling water. Each time I added more salt the temperature was higher than the last one. From the data I collected it shows that the more salt you add the higher the temperature. If you add salt to boiling water the temperature will increase. The data collected shows that my hypothesis was correct because the average number of the different amounts of salt was higher than the last one.…
The English Peppered Moth and Natural Selection Lab By: Justin Pascual Partners: Nathan Magbitang, Rudy Keyes-Krysakowski, and Glenn Tipold Teacher: Ms. Coopman Date Performed: November 16, 2015 The English Peppered Moth and Natural Selection Lab Purpose The purpose of this lab is to determine how variation in a population can favour survival of a certain trait over multiple generations. Hypothesis It is believed that if there are more speckled moths remaining in the tray at the end of the experiment, it will represent the fact that the conditions of the surrounding environment have favoured their colour.…
My hypothesis didn’t support my experiment, but overall I had fun doing this experiment. My experiment was done so I could prove that red potatoes could also grow slips. So, what I did was that I fill my cup with water then I put my potato in and waited. Each day I recorded my data and nothing happened. What happened was one morning when I was going to check on the potato I found it with white blotches around it.…
Our hypothesis was that, if the potatoes were placed in the water then the potatoes would expand because the potato would soak the distilled water if they were placed in other solutions than the potato will lose mass. The Independent Variable is the Types of Solution and, The Dependent Variable is the size of the potatoes.…
Slime is made by mixing together borax, glue, and water. Depending on the amount of borax added to the mixture will determine the density of the slime. For our experiment in class the independent variable was the borax. The dependent variable was slime. The control group was glue.…
Data Analysis The scientific question for this experiment is:” Does the amount of baking soda added to vinegar affect the amount of CO2 produced?” “If more baking soda is added to 50mL of vinegar, then more CO2 gas will be produced,” was the hypothesis. The independent variable was the different amounts of baking soda. Therefore, the dependent variable was the amount of CO2 produced.…
The control was the first row for both amylases. At 0 min. neither one had synthesized anything so this served as the starting point. The independent variable was the temperature; this is what was being changed. The dependent variable was the amylase activity; this is what (should have) changed because of the temperature.…
The results of the experiment was that the worm went toward the water all 3 times. I accept my hypothesis because I correctly predicted that the worm would go to the water. Two possible errors in the experiment is that the paper towels with the substances were not completely flat, and that the saltwater might not have been as salty as water you would find in the ocean. Two improvements would have been to flatten the paper towels, and to get water from the ocean. The final hypothesis is that if worms are placed in an area with rough sandpaper and smooth plastic the worm will move to the smooth plastic.…
