Water is critical to our health and well-being, yet one in three people do not have access to safe drinking water. Earth's water is threatened by pollution, deforestation, urban growth, and climate changes. This article describes a unit for kindergarten children called The Water We Drink.

By hosting a college students' laboratory skills contest, we provide an interesting activity for students to cultivate good laboratory practices and thereby improve their laboratory skills. The substance of this contest is the detection of the hardness of water, which involves numerous laboratory skills such as solution preparation, weight by…

As the use of plastics expands, microplastic concentrations increase in aquatic environments and negatively impact water, soil, and animals inhabiting these areas. Microplastic research frequently incorporates citizen science to assist in data collection and environmental education. These projects provide opportunities for greater societal…

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…

Recently, smart sensing/actuation paper has attracted significant interest due to its potential usage as a sustainable component in future electronics, robotics, and intelligent sensing devices. In acknowledging the importance of this topic for the engagement of students at the university level in conjunction with Industrial Revolution 4.0, it is…

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…

Preventing impairments in athletic performance is an important concept for students that are preparing for careers that involve working with athletes. Gaining hands on, laboratory-based experience in measuring exercise induced dehydration can help students understand how to help athletes prevent dehydration induced impairment in performance. This…

This study aimed to evaluate the effectiveness of a design thinking teaching and learning model on students' design thinking skills in science class. The study utilised two projects, 'Making a Simple Solar Water Heater' and 'Drawing a 3D Topographic Map of Zhejiang Province,' based on the 5th-grade science curriculum in China, and involved 45…

Throughout the country, there are many bodies of fresh water affected by algal blooms. By focusing on a water source near their school, students can become scientists, too. Situating science content in real and meaningful learning experiences encourages students to be invested in their own learning, construct deeper understandings, and apply those…

Groundwater contamination is a serious environmental problem, given that all living things depend on this essential resource. Groundwater represents less than 1% of all water found on Earth, but nearly 90% of the freshwater used comes from groundwater (USGS 2016). The problem-based activity described in this article actively engages students in…

In the current study, an engineering design-based STEM activity was designed and implemented for 5th graders. The current activity is expected to provide guidance and perspective to teachers (practitioners) in designing and implementing an activity based on design-based learning, STEM activity, and engineering design process (EDP). At the same…

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…

Water is a meaningful context for children to engage in inquiry, and to acquire and use science and engineering practices, such as developing spatial thinking and early concepts of water dynamics. This book shows teachers how to provide children with opportunities to engineer water movement through pouring and filling containers of various kinds…

This article describes how fifth grade students participated in a place-based environmental education initiative in West Michigan that supports teachers who want to involve their students in citizen science by protecting local water resources. Every year, Groundswell works with about 100 teachers at 30 schools to engage students in citizen science…

Refraction is a foundational concept within introductory physics. Physics students need a deep understanding of refraction, including Snell's Law, in order to progress towards more complex optics topics such as lenses and images. Unfortunately, many physics students obtain only a superficial understanding of refraction. Although many students can…
