Many simple chemical reactions produce an audible fizz due to the formation of gases, such as oxygen, hydrogen, or carbon dioxide. A hands-on activity based on perceiving these audible chemical changes is presented. The relative quality of fizz due to the formation of gases in a chemical reaction was determined by visually impaired middle and high…

Motivational hands-on workshops for grade-school level future scientists are needed to inspire young and receptive minds. Described here is an educational event, titled "Inspiring Future Rocket Chemists", with hands-on laboratory exercises demonstrating the fundamentals of rocket flight and live chemistry demonstrations illustrating the…

This study investigates the challenge faced by eighth-grade students at Southern State Middle School in grasping abstract concepts within the domains of physical science, physics, and chemistry. This difficulty is manifested in their poor performance on summative assessments. A comprehensive analysis of state-provided data, in conjunction with…

The intervention programmes have a direct influence on teachers' knowledge of teaching different topics. This paper focuses on how Grade 8 natural science teachers' knowledge developed during an intervention programme. Eight schools were selected to participate, and 25 Grade 8 Natural Sciences teachers from Gauteng province participated. Data were…

Nearly 14 million species are estimated to exist on Earth, of which 1.8 million have been identified, and new species are being added to the world of science every day. Therefore, scientists are aware that there are still unidentified species living globally. Biodiversity is a wide concept encompassing all living things in our living space. This…

The purpose of this mixed-method action research study was to improve Black students' performance in my sixth-grade science class by improving their ability to use the claim, evidence, and reasoning (CER) framework. Using criterion-based convenient sampling, I enlisted 17 Black participants, all of whom were underperforming in my science class at…

Biology teachers received professional development to effect instructional changes that ensure student cognitive engagement and knowledge acquisition at higher cognitive levels. We asked the following questions: 1) What are the initial needs of teachers to promote active learner engagement and knowledge acquisition at higher cognitive levels? 2)…

This study aimed to investigate the effects of the applications conducted in the science center within the scope of the science lesson "Solar System and Beyond" unit of the 7th-grade students in the secondary school, on the perceptions of the students about the out-of-school learning environments (OSLEs). In the quantitative part of the…

In the present research, the "DNA Model with Clothespins" activity was designed to teach the subjects of nucleotide, DNA, and DNA replication, which are abstract subjects of science. The aim of the research, which was carried out with 20 students in 8th grade, was to examine the effects of the activity on students' achievement on the…

The aim of the study is to examine the relationship between the learning styles of classroom students in the force and energy unit and their scientific process skills. In the study, pre-test and post-test weak experimental design without a control group was used. The research was carried out in 2 different secondary schools in the central district…

Educators have struggled with maintaining student engagement in science, especially as students transition from primary to middle school and upper grades (Vedder-Weiss & Fortus, 2012). A recent push in science education has been the adoption of the Next Generation Science Standards (NGSS), released in 2013, whose development was guided by…

The construction of a concept can be developed from the students' prior knowledge. Regarding deaf students, it is considered their conceptions conceived through vision. Given this, the present research was conducted with a group of deaf students in the 7th year of elementary school with the aim of verifying what ideas these students had about…

A student's middle school science experience strongly impacts their future science, technology, engineering, and mathematics interest. The Japanese lesson study (JLS) model strengthens the student's experience through a research-based, collaborative, multistep, teaching-centered process focused on transforming local instructional practices. The…

This technology report presents the main features of a free digital educational tool which aims to introduce middle school level students to the comprehension of the particulate nature of matter in the three states (i.e., solid, liquid, and gas) and during phase transitions. This digital tool is available and is freely accessible online. Its…
