Defines approaches to inquiry-based science teaching and describes many ways in which to conduct this kind of science instruction. Argues that with science reform underway, opportunities exist to transform classrooms into environments with active learners engaged in inquiry. (DDR)

Provides an in-depth look at what it means to be scientifically literate. Argues that if teachers are going to help students achieve true scientific literacy, they must agree upon a definition and reach a common understanding of the nature of scientific literacy. (DDR)

Explores the issue of how to make chemistry more personally meaningful to students who have no interest in continuing the study of science. Describes two projects that each have an interview, research, and presentation format. (DDR)

Presents the topic of linking the presence of life on Earth with the chemical evolution of the universe as a whole. The approach involves examining issues related to the biochemical unity of living matter and the chemical evolution of the galaxy. (DDR)

Describes a method that students can use to build portable planetariums. After building the models, students are familiar with the names of constellations and major stars and are able to share their projects with other students. (DDR)

Describes a paper-and-pencil activity that helps students understand DNA sequencing and expands student understanding of DNA structure, replication, and gel electrophoresis. Appropriate for advanced biology students who are familiar with the Sanger method. (DDR)

Describes how students use paper-strip molecules in hands-on activities to show the synthesis of larger organic molecules from smaller molecules. Focuses initially on condensation molecules involving the functional groups in alcohol and carboxylic acids. (DDR)

Criticizes the National Science Education Standards for using an example lesson that contradicts support for students engaging in scientific inquiry. Suggests a multiculturally inclusive approach engaging students in a role-playing activity as members of the University of Alexandria. Students are involved in scientific inquiry with Eratosthenes,…

Describes a curriculum designed around a series of investigative, macroscopic problems that enable students to learn the big picture of modern biology for themselves. Presents a hands-on investigative activity that gives students an accurate, easily grasped analogy for DNA expression. (JRH)

Discusses the use of toys in teaching science. Describes toys that model concepts including Playful Penguins and Blaster Balls; toys in demonstrations such as the Heat Solution, Rainbow Glasses, and Energy Ball; toys as mnemonic devices including Stackable Rings and Color Racers; and toys illustrating science and technology integration such as…

Presents numismatic experiments that cover a range of topics that tie physical science and chemistry to society and history. Discusses measuring length; measuring mass; metals, alloys, and amalgams; reactivity of metals and electrochemistry; reactions of metals with acids; money to burn; magnetic properties of coins; inertia; refraction;…

Describes an approach that challenges students to construct illustrations of chemical reactions by using colorful Bingo card paint markers. Enables them to visually demonstrate their understanding of chemical notations and the law of conservation of mass. Also discusses teaching chemical formulas, a modeling lab, illustrating chemical reactions,…

Describes a learning game called The Business of Life that demonstrates the cellular processes of photosynthesis and respiration as business transactions. Incorporates the ideas that energy flows through ecosystems as well as through cells of individual organisms. Demonstrates the interdependence of living things and that processes at the cellular…

Describes a week-long activity for general to honors-level students that addresses Hubble's law and the universal expansion theory. Uses a discrepant event-type activity to lead up to the abstract principles of the universal expansion theory. (JRH)

Discusses the importance of involving students in assessing the risks versus the benefits of specific laboratory activities, completing accident/incident reports, and performing periodic safety inspections. Concludes that involving students enhances their awareness of both hazards and precautions that must be taken. Provides them another avenue…
