Book Chapter
“Horsing Around”: Curriculum-Instruction-Assessment Problems
The nature of science (NOS) involves actively seeking (rather than avoiding) challenging problems that may require looking at situations differently and thinking outside of artificially imposed constraints. Science, like art, is a creative endeavo...
Book Chapter
Magical Signs of Science: “Basic Indicators” for Student Inquiry
Advertisements capture consumers’ attention and motivate them to buy certain products. Similarly, teachers need to sell science to students by walking the talk of research-informed best practices. Magic signs with (dis)appearing messages (or col...
Book Chapter
Verifying Vexing Volumes: “Can Be as Easy as Pi” Mathematics
Mathematics is both a key to unlocking the secrets of nature and, for many students, a stumbling block to conceptual understanding in science. In this activity, two sheets of 8.5 in. × 11 in. paper are used to construct two cylinders with surprising...
Book Chapter
Bottle Band Basics: A Pitch for Sound Science
In this activity, three identical-size glass soft drink bottles with varying amounts of water are used to make sounds of various pitches. Upon initial consideration, the pattern established when using the bottles as wind instruments seems to suggest ...
Book Chapter
Metric Measurements, Magnitudes, and Mathematics: Connections Matter in Science
This model-building activity helps learners visualize SI’s base-ten relationships; the connections between the meter, liter, and gram; the real-world relevance of mathematics to science; and the somewhat abstract concept of powers of ten that is so...
Book Chapter
Cookie Mining: A Food-for-Thought Simulation
In this activity, various brands, sizes, and textures of chocolate chip cookies are “mined” as an edible analogy for natural resource management and conservation....
Book Chapter
Teachers (or students) are asked to generate and discuss a list of the Top 10 Crazy Ideas in Science and a related list of Top 10 Challenges of Learning Science. This brainstorming activity focuses on science as a school subject that can be mindless...
Book Chapter
In this activity, the wording and validity of the scientific and economic claims for compact fluorescent lightbulbs (CFLs) are critically examined. Their environmental impact relative to standard incandescent lightbulbs is also discussed....
Book Chapter
A Terrible Test That Teaches: Curriculum-Embedded Assessment
In this activity, a “terrible test” appears to be impossible to pass. However, it is intentionally designed to include common errors in item construction that, if noticed, allow the test-wise learner to ace the test without any prior knowledge of...
Book Chapter
Diagnostic Assessment: Discrepant Event or Essential Educational Experiment?
In this activity, learners are asked to complete sample diagnostic assessments that model how nongraded, preinstructional “tests” support learner-centered curriculum and instruction. These kinds of tests, the specific questions asked, and the mis...
Book Chapter
Dual-Density Discrepancies: Ice Is Nice and Sugar Is Sweet
Seemingly identical crystalline cubes (ice versus halite crystals) are observed to either sink or float in two seemingly identical clear, colorless liquids (ethanol and water). Also, a handful of sugar cubes are observed to sink in a container of ...
Book Chapter
Inferences, Inquiry, and Insight: Meaningful “Miss-takes”
The Nature of Science (NOS) includes making scientific inferences based on available empirical evidence (observation) and logical arguments (e.g., prediction based on pattern recognition). Making and learning from “miss-takes” uncovered via sk...
Book Chapter
Pseudoscience in the News: Preposterous Propositions and Media Mayhem Matters
The nature of science (NOS) is to rely on empirical evidence, logical argument, and skeptical review, versus pseudoscience (e.g., astrology), which falsely claims scientific validity and credibility despite the weight of contradictory evidence. Both...
Book Chapter
Scientific Reasoning: Inside, Outside, On, and Beyond the Box
Direct observation, measurement, indirect evidence, and inferential reasoning are used to uncover nature’s patterns and their underlying logic. Scientists use both data interpolation and extrapolation, as well as new technologies, to find ways to p...
Book Chapter
Magic Bus of School Science: “Seeing” What Can’t Be Seen
Scientists use direct empirical and inferential evidence, logical argument, and skeptical review to formulate and evaluate hypotheses and tentative, provisionally accepted theories. In this activity, a simple line-sketch drawing of a school bus cues ...
Book Chapter
Reading Between the Lines of the Daily Newspaper: Molecular Magic
Although there is no single scientific method, scientists use the triple tests of empirical evidence, logical argument, and skeptical review to discover patterns in nature and explain their underlying reasons in terms of naturalistic theories that re...
Book Chapter
Pondering Puzzling Patterns and a Parable Poem
Students and teachers need playful experiences where they can develop the scientific inquiry skills of observation, pattern recognition, and inferential reasoning and prediction, as well as discover some of the perceptual and conceptual biases of hum...
Book Chapter
Astronomical rules are not always correct, especially when they use the word “always.” Students should learn that unless they live on or very near the equator, there are only two days in the year that the Sun rises directly in the east—the sp...
