A collection of four activities for science outreach events was developed to teach middle school students about the temperature dependence of scientific phenomena. Procedures are described for four interactive demonstrations on phase changes, fluorescence, viscosity effects on diffusion, and conductivity. Each hands-on activity helps students…

A versatile and portable apparatus was developed to demonstrate exciting visual displays of catalytic phenomena that introduce basic concepts in catalysis, renewable energy, and chemical safety, in order to pique scientific curiosity in a variety of audiences including middle and high school students, undergraduate and graduate students, and the…

This STEM research project asks middle school or high school students to work towards creating ecologically friendly packaging. Packaging that can be composted instead of thrown away and collected in landfills and oceans like plastics. This inquiry uses nanocellulose and focuses on water permeability. The fibers of nanocellulose can be dried to…

A simple inquiry-based activity called "Fruit Puzzle" was designed to investigate high school students' understanding of the relationship between the concepts of density and solution concentration at a submicroscopic level. The first activity allowed students to predict whether five types of fruit would sink or float in water and asked…

Hydrogel is an interesting topic in polymer chemistry, which is closely related to daily life and advanced technology. In this paper, we report an activity to deliver hydrogel chemistry into middle school classrooms by undergraduates as a bridge between professors and students. During the activity, undergraduates act as a bridge to receive…

Germinating a seed is presumably the first experiment made by a child in his life. So, it has an important place both in child's scientific experience and understanding. Despite the significance of the experiment, the literature indicates that students possess various misconceptions related to the concepts of seed and seed germination. So, it is…

This article develops an emergentist theory of children's agency. To make this claim, it first identifies the following two predicaments that scholars have faced in children's agency research: (1) social ambiguity in distinguishing children's learning from adults' guidance; and (2) causal uncertainty between children's cognitive development and…

Laboratory activity is closely related and yet is essential in the process of science teaching-learning. The hands-on laboratory experiment is the one normally used in school. Particularly with the state of online schooling, it is quite challenging to perform a hands-on laboratory activity. The combination of inquiry-based learning with virtual…

The goal of this study is to present and evaluate a different way of teaching concepts related to the reflection of light (incident beam, reflecting beam, angle of incidence, angle of reflection, surface, regular reflection, and diffuse reflection). The participants were 42 sixth-grade students (between the ages of 11 and 12) attending a public…

The aim of the study was to examine parents' and their children's experiences of science experimentation in terms of parents' roles, science process skills assessed during the experiment and academic successes regarding science lessons. Realization of science activities by students and their parents is at the centre of this study. That is why its…

The Teacher as Partner is an approach to inquiry-based science teaching, where the teacher works as the students' partner. Prior research suggests that it offers an opportunity to model inquiry actions and voice their often tacit rationale. It also enables learners to witness the difficulties and fallibility that even experts can experience, which…

In recent years, the integration of science and mathematics has become popular among educators because of its potential benefits for student learning. The purpose of this study is to introduce a two-day interdisciplinary lesson that brings science and mathematics concepts together, actively engaging students in working with percentages of the…

The ability to design and interpret controlled experiments is an important scientific process skill and a common objective of science standards. Numerous intervention studies have investigated how the control-of-variables-strategy (CVS) can be introduced to students. However, a meta-analysis of 72 intervention studies found that the opportunity to…

Why does a balloon deflate when it is left in a cold car; or why does one have to pump up his or her bike tires in the spring after leaving them in the garage all winter? To answer these questions, students must understand the relationships among temperature, pressure, and volume of a gas. The purpose of the Predict, Share, Observe, and Explain…

Elementary, middle-level, and high school science teachers commonly find their students have misconceptions about heat and temperature. Unfortunately, student misconceptions are difficult to modify or change and can prevent students from learning the accurate scientific explanation. In order to improve our students' understanding of heat and…
