Forensics can serve as the perfect vehicle for science exploration and learning. As part of a professional development workshop, teachers participated in various forensic activities. This article describes an archaeological dig simulation that provides the catalyst for an inquiry-based activity. In this activity, teachers make crime scene…

In a survey of almost 600 high school chemistry teachers, it was found that almost half of them did not use inquiry in their classroom. For the survey, inquiry was defined as any lab in which students write the procedure themselves--the question/purpose/problem could be of the students' own design or provided for them. Many teachers indicated that…

Art provides students a way to visually represent their scientific knowledge and at the same time helps teachers assess student understanding. Examining a drawing allows teachers to scrutinize students' mental model of a science concept. Science can be described as a continuing process of discovering the order and recurring patterns in nature;…

We have developed an introductory bioinformatics exercise for sophomore biology and biochemistry students that reinforces the understanding of the structure of a gene and the principles and events involved in its expression. In addition, the activity illustrates the severe effect mutations in a gene sequence can have on the protein product.…

In this study we investigate students' learning during their interaction with two exhibits at a science center. Specifically, we analyze both students' procedures when interacting with exhibits and their understanding of the scientific concepts presented therein. Bernstein's theory of pedagogic discourse (1990, 2000) provided the sociological…

Humans have long pondered the question of life's origins on Earth and sought to understand their place in the vast expanse of the Universe. Are they alone, in which case the inception of life is a phenomenon unique to planet Earth, or will they find signs of life on other terrestrial bodies? Today, technology allows space probes and rovers to…

Trypsin and soybean trypsin inhibitor (Kunitz inhibitor) can be used in a relatively simple and inexpensive student exercise to demonstrate the usefulness of enzyme kinetics. The study of enzyme kinetics is essential to biology because enzymes play such a crucial role in the biochemical pathways of all living organisms. The data from enzyme…

The best place for students to begin to understand complex environmental relationships is in their own back yards. Doing investigations of ants allows students to establish a baseline survey of ant fauna, test the importance of ants in nutrient cycling and soil structure maintenance, and increase their understanding of the environment and their…

This paper examines what is important about talk between learners during school science and, having identified this, suggests how we can ensure that what we consider important happens. By looking at the interaction between teachers and learners talking about science, it is possible to indicate ways in which learners can be helped to continue this…

Investigates the nature of coaching a high school science olympiad team. The author interviewed nine science teachers about the rewards and challenges of coaching, competition and cooperation, and the relationship between coaching and teaching. Findings include the importance of the social interactions between students and the emphasis on…

Children in South Africa learned to do fascinating activities when they were introduced to the "Spider's Place" materials and, in the process, learned valuable science skills and knowledge. "Spider's Place" was initially a series of 13 science programmes for primary-age children from the South African Broadcasting Corporation…

This article discusses how a regular walk in the wind or the rain can help develop science knowledge and skills. The author describes one "welly-walk" and links it to National Curriculum for England requirements so that readers can see how easy it is. (Contains 1 figure and 1 box.)

The Primary National Strategy for England argues that teachers need use the QCA units of work (or whichever scheme their school follows) only as a baseline or fallback: drawing on their "own" expertise as storytellers, creative thinkers, problem-solvers and as experts on their own pupils, to design activities that are engaging, motivating and…

At home, children often have pets that they take care of and play with; even in the classroom it is not uncommon to find a wormery, an aquarium or an ant farm. However, children rarely have the opportunity to own and care for a plant over a lengthy period of time, let alone a tree. The authors describe a project in Portugal aimed at improving…

These series of lessons uses the process of student inquiry to teach the concepts of force and motion identified in the National Science Education Standards for grades 5-8. The lesson plan also uses technology as a teaching tool through the use of interactive Web sites. The lessons are built on the 5-E format and feature imbedded assessments.
