Representation in science is anything that stands for something else--drawings, pictures, graphs, or other representational forms (Danish et al. 2020). Representations serve as public displays of phenomena that make aspects of those phenomena explicit (Gilbert 2008). They can serve to make the invisible visible, communicate ideas, display…

As an introduction to sound and vibration, the authors wanted their first-grade students to plan and conduct their own investigations. In this article, the authors share a series of investigations to help students explore the relationship between sound and vibration. By planning, creating, testing, adapting, and reflecting on the outcomes of the…

Science and engineering practices (SEPs) and crosscutting concepts (CCs) constitute a significant part of "A Framework for K-12 Science Education" (NRC 2012). As teachers, the role of the authors is to highlight the pivotal role that both scientific knowledge and the practices used to generate knowledge play in learning. This article…

The inclusion of engineering in the Next Generation Science Standards (NGSS) as a key component of K-12 science learning has provided both opportunities and challenges for elementary teachers. One challenge is integrating the design thinking processes that undergird engineering with core science concepts and current issues facing scientists and…

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.

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…

Using cross-grade peer mentoring as an integral component to field trip experiences can help educators realize the learning potential of nature-based experiences. When young students are paired with older students, Socratic peer dialogue deepens interest, investment, and ultimately ownership of new learning. Using peer-supported inquiry…

Engineering has led the way in responding to the COVID-19 pandemic, including developing masks that reduce transmission, digital tools that allow contact tracing, and vaccines that show promise to put an end to the pandemic and allow a more normal way of life. Society is not only "following the science," but is also applying principles…

Although the "Next Generation Science Standards" (NGSS) have three dimensions, the crosscutting concepts are often the forgotten dimension. One reason teachers may not emphasize the crosscutting concepts might be because they are broad, domain-general constructs that can be difficult to conceptualize in a meaningful way. Yet, when taught…

In this article, the authors highlight how a preschool teacher nurtured children's natural curiosity by inviting an expert visitor into the classroom, resulting in many possible investigations. The setting of this activity was an early learning facility at a university with a volcanologist on faculty who was able to share his expertise with…

Children can see the Moon with the naked eye and often are curious about the Moon and other objects in the sky, like the Sun and the stars. However, there is sometimes disagreement in early childhood about whether studying space is appropriate for young children. This activities described in this article engaged children who had different learning…

Visual data--or visual sources of information--are a crucial part of helping students understand STEM concepts, improve their reading skills, and engage in science and engineering practices (Finson and Pedersen 2011). Indeed, many science and engineering practices require students to make meaning from visual data. When students are developing and…

In this essay from a teacher in Argentina, Valeria Vincent describes how she employed Multiple Literacies in Project-based Learning (MLPBL) (Krajcik, Palincsar, and Miller 2015). ML-PBL, an open education free resource, has three design principles that support teacher and student learning and satisfaction. ML-PBL builds on teacher ingenuity and…

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…

Lung cancer is the second most common cancer diagnosis and is the leading cause of cancer-related death in the United States for both men and women. The etiologies of many different types of lung cancer can be linked to risk factors that can be prevented, such as chronic tobacco smoking. Lung cancer is significantly more prevalent among…
