Present research aims to determine the effect of science activities on concept development of preschool period age 5-6 children groups. Parallel to research objective, qualitative research pattern has been the selected method. Study group comprises of collectively 48 children from 5-6 age group attending to a private education institution in city…

Sustainable, or "green," manufacturing and its practices are becoming more and more a part of today's industry, including wood product manufacturing. This article provides introductory information on green manufacturing in wood technology and a crossword puzzle based on green manufacturing terms. The authors use the puzzle at the college level to…

As a primary teacher in a large junior school the author would spend many Sunday afternoons planning exciting science lessons only to find they did not include sufficient mathematical knowledge and skills. At the time, the Numeracy Strategy was spreading through classrooms like wildfire. Meanwhile, science lessons were progressing under the…

This article presents an engineering challenge that the authors have used for a number of years to kick off the science program. It immediately involves all the children, while setting the tone for inquiry and increased levels of student responsibility. The activity, entitled Construction Conundrum, is a lesson written in the design brief format…

Many teachers have taught their share of science lessons that needed improvements. For the past eight years, the authors have been working with elementary teachers to implement quick and easy strategies to modify existing science lessons to make them more inquiry-based. Elementary teachers can use these strategies to adapt existing science lessons…

Primary science has been a major success story over the past 20 years in the UK. Children like science, and teachers, who may not have thought of themselves as "science-trained", have taken to the subject with gusto. Part of this enthusiasm is because of the practical nature of the subject. Science in UK schools makes good use of…

During 2011, a team from the Centre for Science Education (CSE) worked with four local schools and five Sheffield city region engineering organisations on a project to identify ways to increase the input into young people's awareness of engineering that comes from activities they do in school science. The project also tested an hypothesis that…

Nanoporous zeolite foam is an interesting crystalline material with an open-cell microcellular structure, similar to polyurethane foam (PUF). The aluminosilicate structure of this material has a large surface area, extended porosity, and mechanical strength. Owing to these properties, this material is suitable for industrial applications such as…

Inquiry-based instruction in the sciences has been demonstrated as a successful educational strategy to use for both high school and college science classrooms. As participants in the NSF Graduate STEM Fellows in K-12 Education (GK-12) Program, we were tasked with creating novel inquiry-based activities for high school classrooms. As a way to…

As classroom science teachers, we are all often reminded of the inevitable and sometimes not small challenges that face us in captivating and keeping the interest of our students. To give additional relevance and life to my teaching of physics, I decided to integrate global, hands-on projects into my approach. I decided from the onset that the…

The International Olympiad on Astronomy and Astrophysics, an annual astronomy and astrophysics competition for high school students, is described. Examples of problems and solutions from the competition are also given. (Contains 3 figures.)

An undergraduate first-semester general chemistry laboratory experiment introducing face-centered, body-centered, and simple cubic unit cells is presented. Emphasis is placed on the stacking arrangement of solid spheres used to produce a particular unit cell. Marbles and spherical magnets are employed to prepare each stacking arrangement. Packing…

In this exercise, students apply a combination of techniques to investigate the impact of metal identity and ligand field strength on the spin states of three d[superscript 5] transition-metal complexes: Fe(acac)[subscript 3], K[subscript 3][Fe(CN)[subscript 6]], and Ru(acac)[subscript 3], where acac[superscript -] is acetylacetonate. Students…

One of the author's biggest challenges as a preschool teacher is helping children in a group see and touch and do. Hands-on explorations are important for everyone, but essential for young children. How can young children do hands-on explorations of spiders and their webs? Teachers do not want children handling all sorts of spiders. They worry…

For most materials, the solid at and near the triple-point temperature is denser than the liquid with which it is in equilibrium. However, for water and certain other materials, the densities of the phases are reversed, with the solid being less dense. The profound consequences for the appearance of the "pVT" diagram of one-component materials…
