Lab 1: Introduction to Science Exercise 1: Data Interpretation 1. What patterns do you observe based on the information in Table 1? - The more dissolved oxygen in the water the more fish they observed. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. - Having more dissolved oxygen increases the number of fish observed in the body of water. 3. What would your experimental approach be to test this hypothesis? - To test this hypothesis my experimental approach would be testing different bodies of water or testing one and just testing different areas while tracking the fish. 4. What would be the independent and dependent variables? …show more content…
5.6 hours = ________ seconds 3. 13.5 cm= ________ inches 4. 47 °C = _______ °F Exercise 4: Accuracy and Precision 1. During gym class, four students decided to see if they could beat the norm of 45 sit‐ups in a minute. The first student did 64 sit‐ups, the second did 69, the third did 65, and the fourth did 67. 2. The average score for the 5th grade math test is 89.5. The top 4th graders took the test and scored 89, 93, 91 and 87. 3. Yesterday the temperature was 89 °F, tomorrow it’s supposed to be 88°F and the next day it’s supposed to be 90°F, even though the average for September is only 75°F degrees! 4. Four friends decided to go out and play horseshoes. They took a picture of their results shown to the right: 5. A local grocery store was holding a contest to see who could most closely guess the number of pennies that they had inside a large jar. The first six people guessed the numbers 735, 209, 390, 300, 1005 and 689. The grocery clerk said the jar actually contains 568 pennies.

The protein molecules in many foods provide the amino acid building blocks required by our own cells to produce new proteins. To determine whether a sample contains protein, a reagent called Biuret solution is used. Biuret solution contains copper ions. However, the chemical state of the copper ions in Biuret solution causes them to form a chemical complex with the peptide bonds between amino acids (when present), changing the color of the solution. Biuret solution is normally blue, but changes to pink when short peptides are present and to violet when long polypeptides are present.
You can store them on the domain itself and I would say that this is the same as a PKI server because a PKI server has more of a hierarchal ladder of trust to verify users.
The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel, which leaves a clean test tube. Incomplete combustion is the reaction of an element or compound with oxygen to produce some oxides with less oxygen than the most common oxides. Incomplete combustion occurs when there is not enough oxygen to react
designing an experiment, we have to design an experiment and we need to confirm the
Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.
