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…

This paper reports on a study aiming at examining the development of science process skills through the implementation of experiments in a science course which was performed in flipped classroom design. Flipped classroom model was implemented for a series of experimentation activities in a science classroom in which 38 science teacher candidates…

This mixed methods research explored the autonomous experiences of South African school students when participating in a science fair. A prominent global goal for school science education is for students to partake in scientific inquiry in order to acquire understanding of science concepts, the processes and skills of science, and the nature of…

The use of ICT in science education offers many opportunities to promote students' learning and experimenting comprehensively. Considering that, it is important not simply to replace traditional media, but to explicitly identify the added value of ICT tools for students and teachers. Especially alternative forms of documenting experiments,…

The following article presents a concept of a science club which was developed by two master's students as a part of their thesis and which has been developed and improved ever since. The extra-curricular concept emphasises pupils' individuality through focusing on problem based leaning, station learning, and mixed age groups. Having joined the…

Teaching Science can only be successful if we are able to answer the challenges of the 21st century. Teaching Physics, Chemistry and Biology with the traditional methods is unintelligible and considered unnecessary for most students. This situation needs to be changed. Students can only develop their abilities and skills to the full extent and can…

This book for high school students presents 20 different science fair projects that provide an opportunity to learn how plants are affected by natural and man-made influences on their environments. Many experiments in the book were adapted from original International Science and Engineering Fair projects. Each project includes in-depth background…

Presents a set of experiments that explore variables within the steps of the filtration process. (CS)
