How Scientists Work: What is Scientific Inquiry?

From the beginning of human history, natural phenomena have puzzled people and caused them to ask questions. Scientific Inquiry is about answering these questions through investigation. Scientific inquiry is not a precise set of procedure, but rather a broad approach to investigation that ranges from very open-ended to very controlled investigations. Scientific Inquiry begins with questions: “Why? What’s going on? How is this explained?” In this program, we will follow Sherlock Holmes-type investigations in the everyday and natural worlds, leading to some surprising and fun discoveries.

How Scientists Work: What is the Scientific Method?

Scientific method is a time-tested set of procedures used to create an accurate view or representation of the world. Using these procedures, anyone can repeat the experiments that lead a scientist to a result or group of results. In this program, junior scientists show how anybody can find new laws of science through perseverance and careful recording of data.

El método científico y las medidas

This is the Spanish version of "Scientific Method and Measurement."

Lección uno: El método científico, cubre la historia de la investigación científica y los experimentos de Galileo Galilei para probar sus ideas sobre la naturaleza. Los estudiantes verán como Galileo refutó las enseñanzas de Aristóteles quien decía que los objetos más pesados caen más rápido que los livianos. Ellos también aprenderán cómo conducir un experimento propio. Lección dos: Mediciones científicas. Muestra a los estudiantes cómo desarrollar y entender el sistema métrico y la forma en que se utiliza para investigación científica. Se demuestra la utilización de medidas métricas para medir longitud, masa, volúmen, temperatura y densidad. Tambien se demuestra la utilización de equipo común de laboratorio tal como probetas, balanzas métricas, termómetros y reglas métricas.

Lesson One: The Scientific Method covers the history of scientific research and Galileo Galilei's experiments to test ideas about nature. Students will see how Galileo disproved the teachings of Aristotle, who claimed that heavy objects fall faster than lighter ones. The student will also learn how to conduct an experiment of their own. Lesson Two: Scientific Measurement shows students how to develop an understanding of the metric system and how it is used in scientific investigation. The use of metric measurements to measure length, mass, volume, temperature, and density is demonstrated. Common lab equipment is demonstrated, including such instruments as graduated cylinders, metric balances, thermometers, and metric rulers.

How to Use a Microscope

This unit of study has been created to provide students with a knowledge of the history of microscopes and the proper handling and use of these valuable tools. Upon completion of the unit, students should feel comfortable using a miscroscope and preparing slides. They should also have gained an appreciation for the development of different kinds of microscopes and a knowledge of how they are used.

Incredible World of the Microscope, The

Magnifiers and microscopes open a fascinating miniature world where common objects take on awesome, beautiful and, at times, grotesque forms. Viewers will marvel at the multi-faceted eye of a dragonfly, the piercing mouthparts of a tiny flea, the elegant symmetry of growing crystals, blood pulsing through the tail of a goldfish, the frenetic world in a drop of water, and many other specimens as well. Students will not only be captivated by the video’s remarkable imagery, but they will learn how to use magnifiers and microscopes themselves, and discover why the microscope is such an important research tool.
