There are several 'cool' mechanisms that result in materials luminescing or emitting light. Artificial luminescence has often been created by mimicking nature and there are many examples of applications in society. It is very likely that most of your students will have observed luminescence in one form or another, such as glow sticks,…

The Scalable, Interactive Model of an Off-World Community (SIMOC) is a computer simulation of a human habitat on Mars. Built upon decades of NASA research and authentic science processes, SIMOC is both a research-grade simulation and an engaging web-based tool for science education. Users access an intuitive web interface to select mission…

Learning media is a tool that makes it easier for educators to convey material to students effectively and efficiently to improve the quality of learning. Biology subjects in the essential enzymes and cell metabolism competencies require precision and accuracy, so appropriate learning media are needed. Booklets are a medium that can make it easier…

Climate change is a critical scientific and social issue of our time, yet the topic is not frequently discussed by the general public. Additionally, misconceptions about the topic persist. One important aspect of climate change is the greenhouse effect. This activity adds a greenhouse gas discussion to an existing module about molecular shape and…

A Finderscope is a low-power telescope with a relatively large field of view. It has the same line of sight as the main telescope, helping the main telescope easily find the target. One of the differences between a telescope and a finder is that the finder has crosshairs to aid in accurately pointing at a target. You can see the crosshairs and the…

Scientific knowledge is a primary resource that scientists use to shape their activities to make sense of natural phenomena. Support for students' adaptation of scientific knowledge can enhance their ability to make sense of the natural world. This study aims to examine how ecological concepts are used when students plan field-based modeling of…

Electrophilic aromatic substitution (EAS) represents an important class of reactions taught in the undergraduate organic chemistry curriculum. The EAS reaction of benzene and its substituted derivatives is generally described as proceeding through a carbocation (arenium cation) intermediate, and the regiochemistry of the product is heavily…

In conventional physics teaching, acceleration measurement is demonstrated using motion sensors and carts on inclined tracks, and relevant data are collected using specific professional software. This approach entails the connection of computers and interface boxes, and requires high cost and large space. Air-track carts can be used to perform…

The "Next Generation Science Standards" (NGSS) encourages educators to help kindergarteners formalize a big idea in physics: A push or pull can cause an object to begin moving, speed up, slow down, stop, or change the direction it is going (NGSS Lead States 2013). In this article, the authors share an exciting, classroom-tested…

The aim of this study was to examine the effects of STEM activities on students' attitudes towards STEM and problem-solving skills by taking their components into account. An experimental design with pretest-posttest control group was applied in the study. Quantitative and qualitative data collection tools were used. The participants of the study…

An inexpensive at-home quantitative analysis activity was developed for the determination of glucose in unknown samples using paper-based microfluidic devices. All of the materials and reagents for the activity fit in a small kit that was mailed to students. The only items students needed to supply were water and a smartphone. Microgram quantities…

This quasi-experimental design study was conducted to examine the effect of the Science Activities Education Program for Parents (SAEPP) on parents' ability to create opportunities for their children to develop basic scientific process skills at home. The study group consisted of 108 parents (54 experimental, 54 control) whose children attended…

The article presents simple outdoor experiments for measuring illuminance on inclined surfaces with a luxmeter. A hill model is used to investigate the difference in illuminance between a sunny side and a shady side of a hill, with up to a fivefold difference found between the two sides on a sunny day. The illuminance of the sunny side of the hill…

Junior high school is pivotal for developing skills and fostering a lasting interest in science subjects. Understanding the components that either lead to or hinder academic engagement is essential. This research investigates an indicator of the learning environment that significantly influences academic engagement in science of junior high school…

Investigating stars can be difficult. The five-day unit presented in this article is designed for fifth graders to work toward Next Generation Science Standard (NGSS) performance expectation 5-ESS1-1, with each lesson lasting about 30 minutes. Students investigate the relationship between the brightness of light and distance, apply their…
