Exploration of making and changing sounds is part of the first-grade performance expectation 1-PS4-1, "Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate" (NGSS Lead States 2013, p. 10; see Internet Resource). Early learning experiences build toward…

The "Next Generation Science Standards (NGSS)" for K-12 have three dimensions--science and engineering practices, disciplinary core ideas, and crosscutting concepts (NGSS Lead States 2013). "A Framework for K-12 Science Education" states, "Crosscutting concepts have value because they provide students with connections and…

Children may not be aware of the origin of much of their food, especially if they eat mostly processed foods. Schools that operate a garden are able to teach children how common foods are parts of plants. This column discusses resources and science topics related to students in grades preK to 2. In this month's issue students focus on…

Understanding the needs of plants, the function of their structures, and plant reproduction, is part of the National Science Education Content Standard C: Life science (NRC 1996). "A Framework for K-12 Science Education" (NRC 2012) states that by the end of grade 2, students should understand that plants have external parts, used to help…

This article reports on the wonders of winter weather, as it often inspires teachers' and students' interest in collecting weather data, especially if snow falls. Beginning weather data collection in preschool will introduce children to the concepts of making regular observations of natural phenomena, recording the observations (data),…

Talking about death as part of a life cycle is often ignored or spoken about in hushed tones in early childhood. Books with "life cycle" in the title often do not include the death of the living organism in the information about the cycle. The concept of a complete life cycle does not appear in "A Framework for K-12 Science…

Spotting the Moon in the sky is like finding a treasure--unexpected and beautiful. When children look for the Moon in the sky, they don't know where to look. The Moon is far away and most easily observed at a time when most young children are sleeping. Because direct contact isn't possible, adults have to be creative in how they help children…

Early childhood educators contribute to the good health of their students every day. By telling students, "Wash your hands" and "Eat your healthy food first," and providing them time to develop gross motor skills through active play outdoors, teachers hope that students will take the advice with them on the way to a healthy and active lifestyle.…

This column discusses resources and science topics related to students in grades preK to 2. The author discusses teachers using technology to help students develop a science inquiry. Teachers can use technology to help students develop a science inquiry--express ideas, document observations, research information, discuss results, and relate…

An in-depth science inquiry is an ongoing investigation in which children are introduced to materials through hands-on experiences and, with teacher guidance, begin to investigate a question that they can answer through their own actions, observations, and with teacher-assisted research. Qualities that make an experience appropriate to include in…

It is exciting to see children display an interest in discovering the world through their actions. Those actions are the beginning of science inquiry, the process children use to develop knowledge and understanding of scientific ideas, including an understanding of how scientists study the natural world. This month's column features an activity…

There are many ways to share a collection of data and students' thinking about that data. Explaining the results of science inquiry is important--working scientists and amateurs both contribute information to the body of scientific knowledge. Students can collect data about an activity that is already happening in a classroom (e.g., the qualities…

Teachers assess children's learning to understand how to make their instruction more effective. Early childhood assessment must take into account the typically uneven development of children and their cultural contexts. The author assessed what a group of four-year-olds knew about measurement as she talked about how much water had filled a rain…

It's an empowering feeling to be in a room full of people who know the lingo of teaching, who understand the demands of teaching young children, and who want to learn more to be able to put best practices in place in their classrooms. Professional development (PD) can put you there and lead to new ways of teaching, deeper understanding of…

Dinosaurs are one of those science topics that draw children in and teach them about concepts like measuring and using descriptive language. Learning about dinosaurs, although not hands-on like observing and recording caterpillar growth, develops critical thinking and introduces animal diversity and the relations between body form and function.…
