2. To conserve energy, a college student wants to find out the lowest water temperature and the shortest length of time that is needed to wash his clothes and get them clean.
First he tests the effect of time. He washes one shirt for 10 minutes, one shirt for 20 minutes, and one shirt for 30 minutes. The shirts are identical and have identical stains. He uses the same detergent and washes the shirts at the same temperature water.
Why is it important to wash the shirts in the same temperature water?
1. Nothing can be determined about washing clothes from this experimental set up.
2. If he does not wash the shirts in the same temperature water the student cannot find the shortest amount of time that is needed.
3. By washing the shirts in the same temperature water, the student can find out both the lowest temperature and the shortest length of time that is needed.
4. It is NOT important to wash each shirt in the same temperature water because the student is not testing the temperature of water that is needed.
3. A farmer wants to find out which type of fertilizer is best for growing his wheat. He also wants to find out which type of soil is best for growing his wheat.
He does the following experiment using two different types of fertilizer and two different types of soil:
What can the farmer conclude from this experiment?
It is NOT possible to conclude from this experiment which soil is best for growing his wheat or which fertilizer is best for growing his wheat.
He can conclude that Soil B is the best soil for growing his wheat corn and that Fertilizer Y is the best fertilizer for growing his wheat.
He can conclude that Fertilizer Y is the best fertilizer for growing his wheat.
He can conclude that Soil B is the best soil for growing his wheat.

6. Much knowledge gathered by the scientific method is durable. However, scientists still characterize scientific theories as tentative, that is, they are subject to change. Select the best answer that explains why.
New opinions may change scientific theories without evidence
Scientific theories never change.
A scientific theory is just an educated guess without enough proof that it is true.
Science is constantly obtaining new knowledge through new technologies and a scientific theory may change based on new information.
7. In the case study of Alvarez and the KT boundary, how is the scientific process described?
It is a linear process following each step in order ending with more questions
It is a non lenear process, where results often lead to more questions or new hypotheses
It is a linear process following each step in order ending with conclusions.
It is a disordered process, with no method or reasoning behind it
8. In the case study of Alvarez and the KT boundary, the evidence points to many different culprits for mass extinction. Which was the true cause?
None of these causes could be true
All causes could be true
Volcanism
Asteroid impact
Climate change
9. Whether or not oil drilling should be pursued in the Everglades here in Florida is often debated by politicians. Understanding the implications if this is an example of what type of scientific literacy?
