Description
“You will soon be in the lab at the Charles Darwin Research Station on the island of Santa Cruz, in the archipelago known as the Galapagos. You are about to take a virtual field trip to these remote islands. The purpose is to conduct scientific investigations of organisms living there. At the same time you will be exploring biological evolution and the change in populations and species across time.”
These intriguing words introduce students to the virtual fieldwork of this new set, consisting of three multimedia CDs and a spiral-bound Student Field Log. Just as exploring the Galapagos Islands generated questions in Darwin’s mind about how differences and similarities among species came to be, this set acts as a guided inquiry for high school students. It will help them think and act like a scientist—asking questions, making observations, collecting data, and formulating logical explanations for what they observe about the process of biological evolution. The CDs feature vivid activities that simulate fieldwork with the giant tortoise, finch, and iguana in the Galapagos. The Student Field Log provides everything fledgling scientists need—including step-by-step explanations, sheets for recording observations, and background readings—to emulate the process Darwin himself used to develop an explanation for how evolution occurs.
Ideas For Use
Before and since Charles Darwin’s time, scientists have asked many questions about life. Why are there so many different types of living things? Why do all living things share certain basic features? How did each type become adapted to its particular environment? Such curiosity and questioning are the start of any scientific investigation. The nature of the questions asked will determine how an investigation is planned and carried out—that is, how experiments are designed, what kinds of data are collected, and the techniques that are employed.
