In this article, the author describes an activity using physical models -- each a clear plastic box enclosing a miniature coastal town, complete with real water in the "ocean." This activity shows students a natural cause-and-effect relationship that is scientifically simple, yet even many adults don't grasp the worldwide implications:…

In a series of 12 project-based learning lessons, a group of seven fifth-grade students who live 200 miles from the coast explored their personal connections to the ocean. After completing a unit on the role of water in Earth's surface processes, the students investigated ocean acidification and how this pervasive ocean problem impacts their local…

Both children and adults struggle to explain the cause of the day/night cycle and the seasons (Schoon 1995). Early elementary students may not be developmentally ready to explain that patterns of day and night are caused by Earth's rotation on its axis, or that the seasons are caused by Earth's tilted axis as the planet revolves around the Sun.…

What does a scientist do? What is an engineer? What is technology? What do mathematicians do? Questions about the nature of STEM are fundamental to help elementary students gain a deep understanding of the STEM disciplines. Yet, starting a lesson with such abstract questions can be difficult for any learner. Instead, teachers can use concrete STEM…

This article is a presentation of a three-day sequence of lessons that engaged fifth-grade students in an exploration following the activities of scientists. From asking questions and analyzing data, to engaging in scientific modeling, to defending their theories to the scientific (classroom) community, these fifth graders were mirroring how…

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…

Children enjoy water play, and kindergarten children can learn about the water cycle. Teachers are already introducing elements of the water cycle when discussing weather and bodies of water. The water cycle also can be a springboard for teaching children about plants and animals and the importance of water for sustaining life and shaping our…

This column includes activities inspired by children's literature. This month's issue shows that allowing students to use both photographs and information presented through technology helps them begin to construct an understanding of landforms and bodies of water and use models to describe these concepts. This months trade books are: (1) "Our…

The water cycle is a large, complex system that encompasses ideas across the K-12 science curriculum. By the time students leave fifth grade, they should understand "that a system is a group of related parts that make up a whole and can carry out functions its individual parts cannot" and be able to describe both components and processes…

This column focuses on promoting learning through assessment. This month's issue describes using formative assessment probes to uncover several ways of thinking about the puzzling discovery of a marine fossil on top of a mountain.

This column provides background science information for elementary teachers. This month's issue discusses electromagnetic waves.

Where does one single drop of water come from, and what can we do to reduce our water usage? These are important questions that need to be discussed in today's classroom. Helping young children understand the water cycle, the importance of water, and where and how they use water will allow them to be more informed users of this precious resource.…

Picture a wet towel or a puddle of water on a hot, sunny day. An hour later, the towel is dry and the puddle no longer exists. What happened to the water? Where did it go? These are questions that reveal myriad interesting student ideas about evaporation and the water cycle--ideas that provide teachers with a treasure trove of data they can use to…

This column includes activities inspired by children's literature. Elementary students are beginning to understand the Earth's natural processes and humans' impact on the Earth. Humans need the natural resources that the Earth produces, use these resources to develop civilizations, and make decisions to offset the damage they cause, as well as…

We all experience firsthand many of the phenomena caused by Earth's Place in the Universe (Next Generation Science Standard 5-ESS1; NGSS Lead States 2013) and the relative motion of the Earth, Sun, and Moon. Young children can investigate phenomena such as changes in times of sunrise and sunset (number of daylight hours), Moon phases, seasonal…
