The project described in this article took place in fall 2019 and lasted for seven months in a preschool classroom consisting of a master teacher, teacher and assistants, and 21 children (ages 3-5) within a university-based early childhood education center that serves children from birth through six years old. The teachers began the inquiry,…

STEM (Science, Technology, Engineering, and Mathematics) has been at the center of a national conversation around the necessity to strengthen the STEM workforce starting with STEM education in K-12 schools. "The Next Generation Science Standards" (NGSS Lead States 2013) incorporate a prominent engineering component in both disciplinary…

Having high-quality early childhood education programs that prepare children for success in school and later years continues to be an ever increasing national priority. While the "Next Generation Science Standards" ("NGSS") do not provide standards for preschool, there are ample opportunities to use the Standards as a guide to…

The Next Generation Science Standards (NGSS) bring new attention to the role of STEM (science, technology, engineering, and math) in the preK-3 curriculum. However, research indicates that early-childhood preservice teachers feel ill-prepared to teach STEM due to a lack of content knowledge and pedagogical content knowledge. The goal of teacher…

We all "do"--that is, participate in--science in some way. Everyone participates in science as part of their activities of daily living, such as using soap to make hand-washing more effective, using heat to cook food, and closing windows and doors to slow the movement of heat. We may not always identify our actions as a part of…

The "Next Generation Science Standards" ("NGSS") challenge prevalent beliefs that young children are "not ready" to understand natural selection, introducing core aspects in grades 1, 2, and 3 (NGSS Lead States 2013). The authors' research and teaching team engaged in a multiyear project to understand how early grades…

Engaging children's interest, inspiring active exploration of materials, and fostering cooperation between children and adults is the best way to promote the construction of knowledge. Some popular early childhood activities can be expanded to provide experiences and time for children to build on their prior knowledge. This column discusses…

This column discusses resources and science topics related to students in grades preK to 2. In this month's issue students study landscape surfaces to recognize changes due to human impacts or natural phenomena.

In this article, a class of preschool children completed a week of lessons on worms in preparation for a visit by real worms. Prior to the real worm visit, the students learned about the bodies of worms. They also learned vocabulary words such as "segments." They documented thoughts and predictions about worms using drawings. Preparing…

Young children are full citizens. They have full rights to use their "hundred languages," hands, and thoughts to contribute to the field of science. The founder of the Reggio Emilia approach, Loris Malaguzzi, emphasizes in his famous poem that every child has a hundred ways of discovering the world and a hundred worlds to invent. Today's…

"Composting" is a way to purposefully use the process of decay to break down organic materials in a location where the resulting mixture can be harvested for enriching garden soil. The large body of literature about the science of composting provides many options for early childhood educators to choose from to incorporate into their…

This article describes the kindergarten unit on environmental awareness, "Who Wants to Live and Grow in a Garbage Dump?," which integrated life science, health and nutrition concepts, and relationships around the topic of "soil." Science Technology Education and Mathematics (STEM) activities used in the lesson plans were…

Play areas contain objects that fascinate young children. This column discusses resources and science topics related to students in grades preK to 2. This month's issue uses children's interest in collecting outdoor objects to develop their number sense and to build their understanding of math concepts.

During early childhood, children interact with objects around them. During these interactions, they develop their own concepts about matter, even before encountering the word matter in school. When they encounter the concept of matter in school, they develop a beginning notion of matter as the "stuff" that makes up the things around…

Role-play has been shown to increase student engagement and improve the overall classroom environment. When used effectively, role-play can transform a task or assignment to appear more like play than work. In this four-part lesson, role-play was used as a teaching strategy to engage students in learning the science and application of several…
