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…

Design activities can serve as a concrete experience to address the similarities and differences between science and engineering, and also demarcate engineering from tinkering. They can lay the foundation for concept development of targeted disciplinary ideas. Minor, but crucial, changes to classroom tinkering activities along with targeting and…

The article presents a 5E environmental science lesson to help students understand the major environmental factors that lead to acid rain. Students are supported to ask scientific questions to solve the mystery of how acid rain might impact historical buildings. This lesson can be used in a variety of settings both in person and online modalities.…

Water and an immiscible organic liquid are placed in a small plastic bottle. Ten small pieces of a notecard which is shaded on one side by crayon or pencil (graphite or colored) are cut out and placed inside the bottle. After capping and shaking, the notecard pieces float at the liquid-liquid interface with the shaded side facing the nonpolar…

This paper describes the application of an accessible, benchtop mass spectrometer using an Atmospheric Solids Analysis Probe (ASAP) for easy sample introduction, coupled with Atmospheric Pressure Chemical Ionization (APCI) as a soft ionization technique, to the inquiry-based identification of the metal composition of alloys, including coins.…

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…

This meta-analysis explores the impact of informal science education experiences (such as after-school programs, enrichment activities, etc.) on students' attitudes towards, and interest in, STEM disciplines (Science, Technology, Engineering, and Mathematics). The research addresses two primary questions: (1) What is the overall effect size of…

Molecular Cell Biology (MCB) should be taught according to the scientific practices, avoiding cumulative and memory knowledge construction, but favoring scientific thinking. A way to achieve this goal is to apply activities involving scientific news, which construct knowledge through significant learning and the development of critical thinking.…

The aim of this study is to determine the effect of sustainable environmental activities aimed at preschool children on raising environmental awareness. The research was conducted at Baglarbasi Kindergarten in the Haliliye district of Sanliurfa Province, Turkey. A total of 101 children aged 4-5 years participated in the study. Sustainable…

Although there is a push to provide more student agency in science classrooms, teachers and students may become frustrated when inquiry activities and equipment do not work as planned--teachers because of the time crunch to "cover" topics and students because of the perceived lack of value in activities that are "off task." In…

At the end of the 1915 Gallipoli campaign during World War 1, Lance Corporal William Scurry saved thousands of lives with his one simple invention. As the ANZAC soldiers prepared to withdraw from the disastrous 9-monthlong Gallipoli campaign, Scurry came up with the idea of setting up a large battery of rifles that would discharge automatically…

This article describes the NASA-Funded Space Grant Project BOREALIS: "Balloon Outreach, Research, Exploration, and Landscape Imaging System." BOREALIS conducts high-altitude balloon flights to the "edge of space" with flights typically reaching 100,000 feet and a current record flight in the summer of 2020 that reached 126,000…

The standing vertical jump (SVJ) is a classical topic in Newtonian mechanics (Fig. 1). Although the topic has also been treated by others (other terms used are "standing high jump" or "squat jump"), the present paper shows how a smartphone can be used to capture video of a jump and determine the jump height. A crucial…

The purpose of this article is to describe a modeling sequence about the digestive system. "What happens in your body when you have lactose intolerance?" is the initial question that will guide the activities. Students will build a 3D plaster cast of the digestive system as part of a modeling cycle through which they are expected to…

This study adds to the growing body of research on laboratory work. The study involves four pairs of students in a university introductory calorimetry lab of which two pairs, the IR-pairs (infrared camerapairs), were given access to infrared cameras to use however they liked during their course lab work. Two other pairs, the T-pairs…
