An easily constructed and inexpensive polarimeter with an optical rotation angle resolution of about 0.5° is presented. It is made from small pieces of polarizing film, 2 LEDs, a protractor, and a few wires, all held in place with plastic interlocking toy bricks, such as Lego bricks. The instrument was used to demonstrate the optical rotation of…

Students often need to obtain, organize, clean, and analyze data in order to draw conclusions about a particular phenomenon (e.g., why tidal heights change). When conducting a science investigation in biology, chemistry, physics, or Earth science, data can be collected by the student or can be provided to them via secondary data sets. This article…

Space is a key area of science that is often taught in year 5 (ages 9-10) in English schools and related to this is gravitational force. Almost without exception children enjoy learning about the solar system and beyond. This article introduces a series of activities for children to explore the formation of impact craters in the solar system. The…

Dedicated science learning spaces such as science museums, science cafes, or science media attract mostly those who seek out science learning experiences. This self-selection represents a major challenge for broadening participation in informal science learning (ISL). In this study, we examine an approach to ISL that aims at reaching audiences who…

Verbal and nonverbal forms of thinking exhibit widespread dissociation at neural and behavioral level. The importance of this for children's causal thinking and its implications for school science are largely unknown. Assessing 5- to 10-year-olds' responses (N = 231), verbal ability predicted causal reasoning, but only at lower levels, while…

The focus of this study is the co-actings of a 5-year-old girl, a swing, and physical phenomena. The study explores how the swing and physical phenomena worked as co-creators of the girl's scientific explorations as well as her bodily capacities and identity construction. Empirically, the study makes use of a video sequence generated during a…

Background: In England, practical work is a major part of secondary school science and yet little research has examined students' attitudes specifically to practical work. Purpose: To examine students' attitudes to practical work in biology chemistry and physics in secondary schools in England. Sample: The study involved 607 students from Year 7…

Knowing the volume of evolved gases is helpful to select an optimal leavening agent for a particular application. The comparison of leavening agents, their reactions through the baking process in the modern and attractive way, is presented here. A gas pressure sensor probe was used to monitor the pressure change due to the carbon dioxide produced…

In the present study, an experimental teaching material using a soundcard oscilloscope developed for science, technology, engineering, and mathematics (STEM) education considering the engineering viewpoint was applied to address student's misconceptions in the alternating current (AC) circuit topic in high school physics. Four experiments were…

In 1919, Eddington and Dyson led two famous expeditions to measure the bending of light during a total solar eclipse. The results of this effort led to the first experimental confirmation of Einstein's General Relativity and contributed to create its unique and enduring fame. Since then, similar experiments have been carried out all around the…

This paper is about "augmented reality" (AR) and its potentials to support students in handling scientific representations. For this purpose, first representations are examined from a science educational and instructional psychology perspective. After giving a short overview of AR in general and how it can be delineated from…

Research shows that keeping animals in classrooms can have profound effects on student well-being and success. With this practical guide, you will discover how to select a classroom pet, introduce it to students, and design carefully thought-out lessons centered around the animal.

We suggest an activity for measuring the speed of a bicycle going in circular motion by measuring the bicycle's lean angle. In this activity students will be able to feel the strength that is being activated on their bodies while they are moving in circular motion. They will also understand that it is impossible to ride in a circle without the…

This sixth-form chemistry activity describes how students can use acid-base titrimetry to investigate how adding salt to the aqueous phase may change the value of the partition coefficient of an organic acid between water and 2-methylpropan-1-ol. While the presence of lithium chloride and sodium chloride increases the value of the partition…

The aim of this study is to reveal preschool teachers' views on science education, science activities they carry out, methods and techniques they use as well as problems they encounter while performing science activities. This study was carried out according to the case study which frequently used in qualitative research methodology. The study…
