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…

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.

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…

Taking objects apart including old electronics, product packing, and living plants, helps children understand how things work. Documenting this "unbuilding" or "deconstructing" encourages children to first consider the entire object, then the parts, and finally, the purpose of the parts. This article provides a lesson based on…

By observing an organism over time, children can identify patterns in their observations, note growth or other changes, learn about the needs of the organism, and see how the organism creates the next generation of its species; all of these skills are science and engineering practices noted in "A Framework for K-12 Science Education"…

Blowing bubbles is not only a favorite summer activity for young children. Studying bubbles that are grouped together, or "foam," is fun for children and fascinating to many real-world scientists. Foam is widely used--from the bedroom (mattresses) to outer space (insulating panels on spacecraft). Bubble foam can provide children a…

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…

The importance of biodiversity to human life and the benefits of a diverse ecosystem are not often obvious to young children. This column discusses resources and science topics related to students in grades preK to 2. The objective in this month's issue is to introduce children to the diversity of plant life in a given area through a plant…

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…

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…

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.

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),…

This column discusses resources and science topics related to students in grades preK to 2. Articles and lesson ideas for science learning often suggest that teachers have children "document" their observations, but these resources may not offer guidance on "why" teachers should help children document their work,…

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.…

Engineering is such a common part of children's work in early childhood programs that teachers can simply look around the room to identify examples where students have engaged in engineering practices. This article presents a classroom activity that integrates engineering design by building on the everyday problems that young children encounter in…
