Madagascar hissing cockroaches (MHC) are amazing insects that can be an integral part of an effective science learning and teaching environment. MHCs have a fascinating social structure. They make excellent pets, teach students how to properly care for animals, and their large size adds to their "wow" factor. These characteristics make them unique…

In a flexible multisession laboratory, students investigate concepts of phylogenetic analysis at both the molecular and the morphological level. Students finish by conducting their own analysis on a collection of skeletons representing the major phyla of vertebrates, a collection of primate skulls, or a collection of hominid skulls.

Children playing in damp sand invariably try to make a tower or a tunnel. By providing experiences with a variety of materials, alone and together, teachers set up the conditions for children to learn through their senses and ensure that a class approaches a topic with a common set of experiences to build on. Learning about the properties of…

In the western half of the United States, fire bombers are not an uncommon sight. During the "fire season," which can extend from June through November, these specially modified aircraft are used to drop fire retardant chemicals or water on wildfires. It can be an entertaining and instructive classroom exercise to use pictures of these…

The Lawrence Hall of Science, a science center, seeks to replicate real-world engineering at the "Ingenuity in Action" exhibit, which consists of three open-ended challenges. These problems encourage children to engage in engineering design processes and problem-solving techniques through tinkering. We observed and interviewed 112…

Current studies have reported that secondary students are highly engaged while playing mobile augmented reality (AR) learning games. Some researchers have posited that players' engagement may indicate a flow experience, but no research results have confirmed this hypothesis with vision-based AR learning games. This study investigated factors…

Context-aware ubiquitous learning has been recognized as being a promising approach that enables students to interact with real-world learning targets with supports from the digital world. Several researchers have indicated the importance of providing learning guidance or hints to individual students during the context-aware ubiquitous learning…

This study has been created as a qualitative search related the given homeworks in the science and technology courses in order to examine the students' views. The sample consists of 1,539 7th- and 8th- grade students in the city centre of Osmaniye. The search data is obtained from by using five open-ended questions. In the analysis of the data,…

The educational video game Mission Biotech provides a virtual experience for students in learning biotechnology materials and tools. This study explores the use of Mission Biotech and the associated curriculum by three high school teachers and their students. All three classes demonstrated gains on a curriculum-aligned test of science content.…

Primary-aged children's decreasing enthusiasm for science is worrying. The author explores why children are often not as excited by science as one would expect. She found that the best way to counter this is to be enthusiastic about the subject herself, have interesting activities for the children to carry out, and give them a choice about what to…

What are children trying to tell when they can't find the words that they need? Children's gestures are valuable in informing teaching practice and how one goes about assessing children's work in science. These children's gestures may have more meaning attached to it than is at first apparent. Use such gesturing to learn what children know and can…

The natural world fascinates young children. Treasured leaves, shells, stones, and twigs always find their way into the kindergarten classroom. A kindergarten study of collections channels and deepens children's innate impulse to explore and collect. It also lays the foundation for understanding how scientists approach the study of objects in…

We developed a predator-prey activity with eighth-grade students in which they used wolf spiders ("Lycosa carolinensis"), house crickets ("Acheta domestica"), and abiotic factors to address how (1) adaptations in predators and prey shape their interaction and (2) abiotic factors modify the interaction between predators and…

This activity explores the cycling of carbon between the atmosphere (primarily as CO[subscript 2]) and biomass in plants, animals, and microscopic organisms. Students design soil respiration experiments using a protocol that resembles current practice in soil ecology. Three methods for measuring soil respiration are presented. Student-derived…

A new group educational activity based on a treasure hunt is described. Students are asked questions and the answers specify a grid on a map. A specified object in the grid location must be found and photographed, and the photograph submitted electronically (through the Learning Management System) for assessment. Once a series of objects in…
