This article introduces a flexible and easy-to-implement open-ended scientific inquiry activity called the Paper Towels Challenge. After experimentally determining which of three unbranded paper towels is the most absorbent, students discuss their results and methods. The teacher facilitates the discussion of epistemological issues. This activity…

Mosquitoes (Culicidae) are disease vectors, which are responsible for an estimated one million deaths per year. Female mosquitoes, which need blood for survival and reproduction, collect blood with a disease present from a host, and will transmit that disease from one host to another as it feeds on additional food sources. This continuous feeding…

Gamified-integrated STEM is a technique that combines integrated STEM stages with gamification elements and can engage individuals in climate change communication. This paper presents a gamified-integrated STEM activity focused on global climate change. The activity includes gamified-integrated STEM instructional stages implemented in 6 lesson…

School science is often very different from "real world" science. One important difference, and possibly the main one, is that in school science the relationships between variables have often been sanitized -- essentially "cleaned up" -- so that there is very little (and often no) variation in the data from the relationship…

It may be asserted that there is no more effective deterrent to crime than the certainty of detection. Equally true is that there is no surer way to establishing identity than by fingerprints. The detection of fingerprints at the scene of crime is therefore one of the most powerful tools available in casework investigations. However, if the crime…

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…

Kids are drawn to dolls and dump trucks, and crashing the two together might just be a child's favorite pastime. Who knew such a simple pleasure could serve as an accessible, compelling phenomenon for instigating investigations of force and motion. With a few inexpensive materials straight out of the toy box (literally, a doll, a dump truck, a…

This paper explores the use of comics as an integrated tool for introducing socioscientific issues (SSI) in elementary school classrooms. To illustrate this, we provide implementation examples from two teachers who facilitated introducing SSI to students using comics. These case studies depict how teachers integrated comics into their classroom…

This study presents a rollercoaster activity including virtual reality and following the six-steps engineering design process. In the study, a real-life problem involving a rollercoaster accident was given to 12 pre-service science teachers first. The participants were then asked to imagine, plan, create, and test a rollercoaster without an…

In this article, simple models of optical computing circuits (1 x 4 demultiplexer (DEMUX), 4 x 1 multiplexer (MUX), Boolean logic, and half-adder (HA)) are shown with mechanically controlled plane mirrors. Photographs of the proposed computational circuits are also shown. It is very useful for the school student to understand optical logic and…

Our 4th grade year has become known as "the field trip year", with over 10 trips carefully aligned with learning units across the year. This article describes the first trip of the year, which in many ways sets the stage for students' effective use of field trips as engaging extensions and applications of classroom learning. The Pike's…

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…

To foster students' meaningful learning of science, we designed and implemented a unit for five third-grade students that allowed them to understand Carbon Footprint (CF) in a public school in North Texas. The unit lasted seven weeks, where students identified the effects of distance traveled and packaging on the CF of certain consumable products.…

Below the surface of the ocean, currents, eddies, and other physical processes redistribute energy and biologically important elements. Measuring this transport can be challenging, and scientists must address a wide spectrum of oceanographic and engineering concepts when designing instruments to observe these processes. In this activity,…

Oftentimes, due to the involute nature of the issues involved, society leaves it up to the experts to tackle the environmental problems currently facing society. However, a more wholistic approach is needed to address these environmental issues in the timely fashion necessary. With a reductionist treatment of sustainable development issues, the…
