Question 16
Shari was in the kitchen when she heard a crash. She went into her bedroom and found her window broken and a baseball lying on the ground. Shari said "this baseball broke my window.” This statement is an

inference because she is blaming someone else for the broken window.
inference because she drew a conclusion based on evidence.
observation because she heard the crash before she came into the room.
observation because she can see the evidence

Question 17
Which of the following is an example of a scientific inference?

The insect probably released a sticky liquid because it is upset and trying to defend itself.
The butterfly has bright colors that make it easy for me to see when it lands on a plant.
The ants live in colonies and they follow trails to find possible food sources.
The bee stung me on the arm after I waved my hands trying to scare it away.

Question 18
Scientists often investigate alternative explanations for the data and observations presented, even once a hypothesis has been tested and supported through an experiment. This investigation of alternative explanations

keeps the scientific community competitive and motivated.
strengthens the evidence and support for a scientific theory.
demonstrates that scientific theories are based on opinions.
proves that scientific theories are not able to be disproven.

Question 19
A scientist working in the rainforest is investigating the use of tree frog toxins as medicine by the natives. Why is it important for the scientist to keep accurate notes about his investigation?

Accurate notes are required to prove that he is the one who discovered the toxins.
Accurate notes are necessary in case he gets sick from the experiment.
Accurate notes will help to ensure that no one copies his experimental methods.
Accurate notes will help other scientists test his finding to see if they are valid.

Question 20
After analyzing rock core samples in an area with frequent earthquakes, many geologists believe a severe earthquake will occur in the area in the next 50 to 80 years. Other geologists, however, believe that such a prediction cannot be determined from the data collected. If these two groups of scientists have access to the same data, how can they form such different hypotheses?

a Geologists manipulate data to fit their hypotheses, which results in different conclusions.
b Scientific predictions must list every possible outcome to make sure that they are never incorrect.
c Geologists have different specialties that can cause them to interpret data differently.
d Scientific hypotheses need to be proven many times, so predictions of earthquakes are probably incorrect.
