Reading:
Suggestion for Introductory Science Courses
In most introductory-level science courses, the only reading students are required to do comes from a textbook. However, I think students taking introductory science courses should also be required to read recent articles from academic research journals. Reading journal articles would benefit introductory science students by making them familiar with some of the newest and most up-to-date research in their field, something that textbooks don’t always have. Also, the professors of these introductory courses could teach students how to locate journal articles and other online academic resources in class, which would provide students with useful skills for when they eventually take more advanced courses.

Task3
Reading:
Indirect Mimicry
Over time, animal species have developed many different ways to protect themselves from predators. Some animals use indirect rather than direct means to do this-for example, an animal might create an object that looks like it to attract the attention of potential predators. This defensive strategy is known as indirect mimicry. Animals that use this strategy take material from the surrounding environment and use it to create copies of themselves. As a result, predators that see the mimicked or copied object-the imitation of the real animal-may become confused and attack the imitation instead of the animal. This gives the real animal an opportunity to escape.
Explain how the example from the professor’s lecture illustrates how animals use indirect mimicry to avoid predators.
Task4
Summarize the lecture about locating archaeological sites. Be sure to include the professor’s points and examples.
