This unit is a different and fun way to engage students with an extremely important topic, climate change, which cuts across scientific and nonscientific disciplines. While climate change itself may not be listed in the curriculum of every science class, the authors contend that such a unit is appropriate for virtually any science curriculum.…

This article discusses an instructional strategy which explores eventual similarities and/or analogies between familiar problems and more sophisticated systems. In this context, the Atwood's machine problem is used to introduce students to more complex problems involving ropes and chains. The methodology proposed helps students to develop the…

The Association for Science Education's "schoolscience.co.uk" and Martin Rapley, presenter of "The Big Bug Experience," are again running the Great Bug Hunt in 2012. Simply identify a habitat, explore and discover the bugs that live there, photograph or draw them and record findings--it's that simple. The winner will be the…

We describe a technique for removing and growing chick embryos in culture that utilizes relatively inexpensive materials and requires little space. It can be readily performed in class by university, high school, or junior high students, and teachers of any grade level should be able to set it up for their students. Students will be able to…

The cycle of duplication and division, known as the "cell cycle," is the essential mechanism by which all living organisms reproduce. This activity allows students to develop an understanding of the main events that occur during the typical eukaryotic cell cycle mostly in the process of mitotic phase that divides the duplicated genetic material…

An easy-to-complete, microwave-assisted, green chemistry, electrophilic nitration method for phenol using Cu(NO[subscript 3])[subscript 2] in acetic acid is discussed. With this experiment, students clearly understand the mechanism underlying the nitration reaction in one laboratory session. (Contains 4 schemes.)

The growth of pollen tubes is one of the most characteristic events in angiosperm reproduction. This article describes an activity for visualizing the journey and guidance of pollen tubes in the reproductive structures of a flowering plant. The activity uses a semi-in vivo system with rapid-cycling "Brassica rapa," also known as Fast Plants.…

This article provides an example of an innovative science activity applied in a science methods course for future elementary teachers at a small university in northeastern Turkey. The aim of the activity is to help prospective elementary teachers understand the density concept in a simple way and see an innovative teaching example. The instructor…

While increasing evidence points to a critical role for the motor system in language processing, the focus of previous work has been on the linguistic category of verbs. Here we tested whether nouns are effective in modulating the motor system and further whether different kinds of nouns--those referring to artifacts or natural items, and items…

In the current study, we focus on teacher-student discourse in Pre-K science activities, with particular attention to teacher questioning. Videotaped classroom observations and teacher interviews served as the corpus of data. Overall, teachers asked mostly closed-ended questions, but used more open-ended questions when experiments were being…

With the increased focus on both inquiry and 21st-century skills such as collaboration and problem-solving, teachers at all levels are looking for engaging ways to create more student-centered classrooms in which students can learn more than "just" science content. Discovering and developing creative science activities designed to accomplish…

Making ice cream! Dissecting a cow's eye! Spinning glasses of water without spilling a drop! Investigating fingerprints! These are just samples of what elementary children did at the Jersey City Public Schools very first districtwide "Family Science Night." Although there was some stress in preparing for the evening, it turned out to be a…

Thermal cameras are useful tools for use in scientific investigation and for teaching scientific concepts to students in the classroom. Demonstrations of scientific phenomena can be greatly enhanced visually by the use of this cutting-edge technology. (Contains 7 figures.)

Google Earth is an exciting way to engage students in scientific inquiry--the foundation of science education standards and reforms. The National Science Education Standards identify inquiry as an active process that incorporates questioning, gathering and analyzing data, and thinking critically about the interplay of evidence and explanations.…

Grounded in theory and best-practices research, this practical text provides elementary and middle school teachers with 40 place-based activities that will help them to make science learning relevant to their students. This text provides teachers with both a rationale and a set of strategies and activities for teaching science in a local context…
