The author discusses the different meanings of the words "prediction" and "hypothesis". Recognizing the difference can help students approach the inquiry experience in a way that teaches them to communicate their reasoning and rationales. Better understanding of these two terms can also help teachers create more effective assessments of process…

Misconceptions about sinking and floating phenomena are some of the most challenging to overcome (Yin 2005), possibly because explaining sinking and floating requires students to understand challenging topics such as density, force, and motion. Two scientific principles are typically used in U.S. science curricula to explain sinking and floating:…

Instructional inquiry models are curricular and instructional practices that can promote, facilitate, and engage students in scientific inquiry and science content. However, current, existing learning-cycle models do not specifically incorporate essential instructional teaching strategies that promote or document strong conceptual understanding…

Cookbook labs have been a part of science programs for years, even though they serve little purpose other than to verify phenomena that have been previously presented by means other than through investigations. Cookbook science activities follow a linear path to a known outcome, telling students what procedures to follow, which materials to use,…

In this article, the authors present an inquiry-based approach to facilitate student understanding of the differences among common cloud descriptive characteristics through the use of a semi-dichotomous key developed by a former West Virginia state climatologist. The authors also demonstrate how students can analyze common class data sets that…

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 Next Generation Science Standards (NGSS)--now in development--will be based on "A Framework for K-12 Science Education" released by the National Research Council last summer. The "Framework" identifies seven scientific and engineering practices that should be used in science classrooms. These practices reflect the multiple ways in which…

The pitcher throws the ball and the batter takes a mighty swing. Crack! The ball is hit on the sweet spot and soars to the outfield. Or, you hear a thud! This time, the ball dribbles along the infield ground and the batter's hands sting. Everyone who has played baseball or softball has probably experienced both of these outcomes. This may not seem…

As any contemporary teacher knows, credit and credibility are showered on those who engage in research-based practices. And not just any research. It must be tied to a study with a large enough number of participants; a clear intervention; control and experimental groups; results that can be scaled up and replicated... Wait! Is this the only kind…

Students come to class with diverse experiences and backgrounds, and the author tries to take advantage of that diversity in the plant unit. Every year the author secures the help of the two or three green thumbs or green-thumb wannabes to help take care of the collection of plants she brings from home in the fall. The author also invites students…

Schools are under increasing pressure to meet accountability requirements and show growth in student achievement across tested content areas. As a result, throughout the school year, student achievement data are analyzed to discover data trends that highlight both student gains and gaps in learning. Achievement gaps are identified and addressed…

Chia seeds will sprout on almost any moist surface, and they respond quickly to experimental variables. Furthermore, the newly recognized nutritional value and rich cultural history of chia seeds offer the possibility of highly motivating and educational interdisciplinary extensions, especially appropriate to students in the middle grades.…

Having students design their own methods regarding data collection during a lab may help them formulate appropriate investigative procedures. The authors use a modified gallery walk to develop science skills. (Contains 3 figures.)

The activity described here uses the creative natures of visual art and music to enhance students' potential for creativity while increasing their understanding of the science associated with force and motion. Students design, test, and redesign a sailboat vehicle; collect data; make interpretations; and then defend their design. Music is used to…

Visuals play an important role in the teaching and learning of science and should be embedded within and supportive of authentic science inquiry. Both researchers and teachers believe that visuals have a great deal of potential to help students understand science, but in practice, these visuals do not always live up to their promise. Teachers need…
