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…

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…

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

Science fairs have the potential to help students develop new ways of solving problems using a scientific approach. This supplemental guide was developed for those teachers involved with science fairs as well as others who work with students in developing a project. Several reasons for holding a science fair are listed, along with some…
