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?
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.
