Classical phenylketonuria (PKU) is caused by a lack activity in the enzyme phenylalanine hydroxylase, leading to elevated concentrations of phenylalanine in the blood. A simple demonstration and three advanced demonstrations of a spot test for phenylpyruvic acid and its relationship to phenylketonuria are given.

Modern low-cost data acquisition systems enable pupils to study the voltage-current characteristics of a wide range of different materials and devices in a quick and convenient way. In particular, it is possible to study materials, such as meat and vegetables, not normally associated with school physics experiments.

In September 2005, Beaumont Leys Secondary School gained Specialist Science status. As part of this new role the secondary school decided to support its ten feeder primary schools, which were close enough geographically to allow both daytime and twilight activities. Having gathered information about their in-service needs, Beaumont Leys offered a…

Few European countries have developed a broad strategic framework to raise the profile of science in education and wider society. However, a wide range of initiatives have been implemented in many countries. The impact of these various activities is nevertheless difficult to measure. School partnerships with science-related organisations are…

Academics preparing students for experiential placements within professional programs require considerable curriculum planning and pedagogical expertise. Communities of practice involving workshops and online processes provide opportunities for collaborative work in developing quality curriculum materials and also in supporting widespread…

This module provides a set of quantitative snapshots of the Community Science Workshops (CSWs) to complement the other reports that comprise the CSW Evaluation Portfolio--the Description of CSWs, the Benefits to Youth, and the Evaluation Brief modules--and to build a solid representation of the scope and scale of the CSW's work and…

Where does cellular respiration take place? How does a plant make food and in turn use the food to produce its own energy? Do animals carry on this process also? To help students answer these and other questions, have them build a model leaf, plant cell, and animal cell. This hands-on project allows students to see and manipulate the reactants and…

Inspiring students to learn about birds can be a daunting task--students see birds just about every day and often don't think twice about them. The activity described here is designed to excite students to "become" birds. Students are asked to create a model and tell the life story of a bird by mapping its migration pattern. (Contains 6 figures, 6…

Opaque film canisters are readily available, cheap, and useful for scientific inquiry in the classroom. They can also be surprisingly versatile and useful as a tool for stimulating scientific inquiry. In this article, the authors describe inquiry activities using film canisters for preservice teachers, including a "black box" activity and several…

Today there are little more of 3 million chemist all over the world producing about 800,000 papers a year. They produce new substances--from some hundreds in 1800 to about 20 million now--the vast majority artificial. This rate is growing quite fast. Once the majority of chemistry teachers all over the world used textbooks as the main (sometimes…

The purpose of this activity is for students to build a rainstick out of materials in their own environment and imitate the sound of rain while investigating the physical principles of sound. Students will be able to relate the sound produced by an instrument to the type and quantity of materials used in its construction.

To help students develop an understanding of the proper use and function of spectrographs and monochromators we describe a student-assembled spectrograph using a "webcam" detector. The apparatus also works well as a low-cost demonstration, helping students make connections between an atomic spectrum observed by eye and a plot of the relative…

Students with disabilities (SWDs), students at risk, and even honors students can have a hard time relating to traditional science instruction and often disengage. However, research has shown that when science teachers use inquiry or activities-based approaches to teaching science, students' achievement is significantly higher, compared to those…

The kids in today's classrooms spend lots of time playing video games, surfing the net, listening to iPods, and text messaging on cell phones. Known as Digital Kids and the Net Generation, they have grown up surrounded by digital media of all types (Tapscott 1999). Because they are already knowledgeable, why not use digital technologies to capture…

CCD spectrometers available at Stockholm House of Science allow students to measure the radiation from the Sun. Students are fascinated by the information that can be gathered from the spectrum, including the temperature of the solar surface and the presence of certain elements in both the Sun's atmosphere and the Earth's.
