This work reports the development and application of an analytical tool for the analysis of the formation of the scientific mind of students who took part in inquiry activities, based on the philosophy of Gaston Bachelard, in a Chemistry Club. For the construction of the analytical instrument, an extracurricular course was offered to first-year…

Techniques from the branch of artificial intelligence known as machine learning (ML) have been applied to a wide range of problems in chemistry. Nonetheless, there are very few examples of pedagogical activities to introduce ML to chemistry students in the chemistry education literature. Here we report a computational activity that introduces…

The topic 'Animals including humans' runs through the primary science National Curriculum in England (DfE, 2013). Ideally, topics such as inheritance will lead onto adaptation, natural selection and evolution across key stages 1 to 2 (ages 5-11). This article provides nine engaging activities to support the teaching of adaptation and improve…

This study analyses the effectiveness of ethnobotanic activities on learning performance of pre-service teachers about plants' classification. The research design was a quasi-experimental model. The results of the study revealed that the experimental group in which ethnobotanical activities were carried out was more successful for answers given to…

The present research aims to analyze the publications related to astronomy education that discusses the interface between formal education (FE) and non-FE (NFE) at scientific events and a journal in the Brazilian context. These events were the National Symposium on Astronomy Education, the National Meeting on Research in Science Education (ENPEC),…

The Periodic Table of Elements is a valuable resource for chemists and all kinds of STEM professionals. However, it can be initially overwhelming and intimidating to some students. This hands-on lesson introduces abstract concepts in the periodic table through a tangible experience with simple toys and household objects. Students collaborate and…

Classroom implementation of the "Next Generation Science Standards" (NGSS Lead States 2013) does not necessarily require complete curricular overhaul. In many cases, teachers can review previously used lessons with respect to the "NGSS," evaluate alignment, and make subsequent modifications. One science activity the author has…

The unique organism project was designed as a culminating assessment for a biological classification unit in a middle school setting. Students developed a model to represent their unique organism. Using the model, students were required to demonstrate how their unique organism interacts with its environment, and how its internal and external…
