Estimation is an important skill that we rely on every day for simple tasks, such as providing food for a dinner party or arriving at an appointment on time. Despite its importance, most people have never been formally taught how to estimate. Estimation can also be a vital tool for scientific inquiry. We have created an activity designed to teach…

A two-part demonstration was conducted in our first-semester organic chemistry course designed to introduce students to the formation of alcohols, regioselective reactions, and analysis of organic products by NMR analysis. This demonstration utilized the oxymercuration-demercuration sequence to prepare an alcohol from an alkene in a Markovnikov…

Why are there only crumbs left at the bottom of the cereal box? Many factors, such as package handling, have caused the cereal pieces to break down into crumbs. This explanation is also related to the process of creating sediment from rocks. Sediment is created by weathering over millions of years, and it is deposited all over the world by…

This study examines ideas of pre-service teachers on goals of biology practical in three purposely selected Colleges of Education. To this end, A researcher designed questionnaire which was adapted titled "views of preservice teachers on biology practical" to elicit information, and findings of a survey administered to 405 preservice…

The power of 3D printing technology has grown exponentially in just the past few years--people around the world are using 3D printers to prepare food, create tailored clothing, build cars and homes, and advance the medical field in ways that never seemed possible. In classrooms across the nation, 3D printers have become increasingly common because…

Neo magnets are neodymium magnet beads that have been marketed as a desktop toy. We proposed using neo magnets as an alternative building block to traditional ball-and-stick models to construct carbon allotropes, such as fullerene and various nanocone structures. Due to the lack of predetermined physical connections, the versatility of carbon…

Most high school and introductory college physics classes study simple harmonic motion and various wave phenomena. With the majority of states adopting the Next Generation Science Standards and pushing students to explore the scientific process for themselves, there is a growing demand for hands-on inquiry activities that involve and develop more…

Seeking a historical-philosophical approach to science teaching, narrative texts have been used as pedagogical tools to improve the learning experience of students. A review of the literature of different types of narrative texts and their different rates of effectiveness in science education is presented. This study was developed using the…

Within the past 10 years severe weather has been responsible for an annual average of 278 fatalities in the United States (National Weather Service, 2013). During severe weather special populations are populations of high concentrations of people that cannot respond quickly. Schools show both of these characteristics. The average lead time for…

Considerable anecdotal evidence indicates that some of the most difficult concepts that both high school and undergraduate elementary-education students struggle with are those surrounding evolutionary principles, especially speciation. It's no wonder that entry-level biology students are confused, when biologists have multiple definitions of…

For students in biology, chemistry, or environmental science, diatoms offer excellent insight into watershed health and human impact on the environment. Diatoms are found globally in virtually every habitat that has sunlight and moisture, including polar seas, tropical streams, and on moist soils and mosses. Studying diatoms as biological…

This comparative study examines the way in which preschool teachers support children's science learning in a Chinese and a Norwegian kindergarten. The study takes an ethnographic approach. Preschool teachers from one kindergarten in Shanghai and one in Bergen were asked to videotape educational activities that focused on science in their…

Surveillance cameras are prevalent in various public and private areas, and they can also be coupled to optical microscopes and telescopes with excellent results. They are relatively simple cameras without sophisticated technological features and are much less expensive and more accessible to many people. These features enable them to be used in…

Educational stakeholders across the globe are demanding science education reform that attends simultaneously to culturally diverse students' needs and promotes academic excellence. Although professional development programs can foster science teachers' growth as culturally responsive educators, effective supports to this end are not well…

The acquisition of everyday scientific concepts by 3-6-year-old children attending early childhood institutions has been widely studied. In contrast, research on science learning processes among younger children is less extensive. This paper reports on findings from an exploratory empirical study undertaken in a "stay and play" service…
