Less than a century ago, astronomers began to unlock the cosmic distances within and beyond the Milky Way. Understanding the size and scale of the universe is a continuing, step-by-step process that began with the remarkably accurate measurement of the distance to the Moon made by early Greeks. In part, the authors have ITEAMS (Innovative…

What do paleontologists, dinosaur tracks, and the nature of science have in common? They're combined here in an inquiry activity where students use methods of observation and inference to devise evidence-based explanations for the data they collect about dinosaur tracks, much like the methods used by paleontologists. Students then debate the…

The modified Mercalli (MM) intensity scale is composed of 12 increasing levels of intensity that range from imperceptible shaking to catastrophic destruction and is designated by Roman numerals I through XII. Although qualitative in nature, it can provide a more concrete model for middle and high school students striving to understand the dynamics…

Although inquiry is more engaging and results in more meaningful learning (Minner, Levy, and Century 2010) than traditional science classroom instruction, actually involving students in the process is difficult. Furthermore, many students have misconceptions about Earth's seasons, which are supported by students' prior knowledge of heat sources.…

Encouraging students with learning challenges to actively participate in the learning process can be difficult, especially when they are tentative about their knowledge level as compared to their peers. This article outlines three steps teachers can take to incorporate cooperative learning strategies that ensure active participation by all…

If we want our students to become capable practitioners of scientific inquiry, we should not stop at providing opportunities to do inquiry. We need to be intentional about assessing and teaching the competencies necessary for inquiry. However, the ability to conduct scientific inquiry can be difficult to assess. Therefore, the author created The…

One of the largest challenges of teaching astronomy is bringing the infinite scale of the universe into the four walls of a classroom. However, concepts of astronomy are often the most interesting to students. This article focuses on an alternative method for learning about stars by exploring visible characteristics of the constellation Orion and…

To teach scientific literacy to eighth graders, the authors created a yearlong project that emphasizes the various components and skills required to be a scientifically literate citizen. This project is broken into four separate components: skeptical thinking (pseudoscience), current-event article analysis, fiction and nonfiction literature, and…

This investigation was part of a multi-lesson unit that gave students direct experience using increasingly sophisticated tools to make more detailed observations and measurements of light. Through these lessons, students experienced a key aspect of the nature of science (McComas 2004), namely how scientists constantly refine and modify theories as…

To introduce students to rocks and their characteristics, teacher can begin rock units with the activities described in this article. Students need the ability to make simple observations using their senses and simple tools.

By virtue of its connection with scientific literacy, the nature of science has been considered essential subject matter for the science curriculum. With this in mind, seventh-grade students were introduced to three aspects of the nature of science: (1) the distinction between observation and inference, (2) the subjective, and (3) the tentative…

It is often said that a dog is a best friend. In fact, after cattle, dogs are the oldest domesticated animals. Dogs have lived with humans for over 10,000 years and have been selectively bred for various types of domestication. Domesticated dogs have performed many roles in society throughout history-rescue dogs, hunting dogs, guide dogs, and…

Discusses the importance of observation in science education, how to foster students' observation skills in the classroom, and how to facilitate what they observe when learning. Includes a list of components of good scientific observing. (KHR)

The author's favorite way to start the new school year is to perform a science demo for students. At the beginning of the period, he discusses the importance of making accurate observations. He tells them that he will perform a short demonstration that they are to carefully watch and then record their observations. They each have a sheet of paper…

In the introductory assignment, each randomly assigned group spends about 10 to 15 minutes at each station. The author incorporates as much sensory stimulation in the activity as possible. At the first station, students view a PowerPoint show from a geology class the author participated in at the Grand Canyon. At station two, students look at a…
