Poinsettia ("Euphorbia pulcherrima") contains anthocyanins that dissolve in water and exhibit color changes due to changing pH. This property makes the poinsettia extract a useful acid-base indicator for pH demonstrations. When combined with common household materials, this experiment can be used as an alternative low-cost tool in…

The COVID-19 pandemic posed significant challenges for practical teaching within the sciences. While many instructors adopted innovative alternatives to conventional practicals, many relied on digital approaches that did not give students hands-on experience. In this study we evaluate the use of 'at home' practical kits used in first year physics…

Describes a pilot project for the home-study component of a first-year general chemistry course at Athabasca University that uses microscaled experiments. Presents four experiments and discusses home-study versus in-lab experience. (JRH)

Presents an inexpensive take-home laboratory activity designed to enhance students understanding of atmospheric pressure by allowing them to engage in a hands-on, discovery approach to physics. (ZWH)

Describes a take-home experiment in which students measure the diffusion of acid through acid-filled capillary tubes immersed into base solutions and vice versa. Students represent and analyze the effects of ambient temperature, molecular weight, and concentrations of the solutions on that movement. (MDH)

Suggests seven take-home experiments geared toward the topic of energy that can be utilized in large, general-education physics classes that do not include laboratory sessions. An appendix provides details for the experiment to measure the heat of fusion of water. (MDH)

Many educators feel that elementary school science programs should concentrate on phenomena and concepts that are literally tangible. This document serves as the teaching manual which accompanies the Capsela modular system of manipulative and motorized models. The experiments in the manual are intended to provide a structured approach to using the…

This book addresses some of the methods by which science can be made accessible to children, both in school and non-school settings. It contains information on effective science education for elementary school age children, and includes a catalog of books and other materials. Topics discussed in the book include: (1) planning; (2) approaches to…
