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…

Making and recording scientific observations is a fundamental activity of the scientific community. Scientists use their senses and tools (e.g., magnifying glasses, rulers, colored pencils) to make records of the phenomena (e.g., light energy, ecosystems) they are investigating. These observations often serve as evidence in the scientific…

Every high school graduate should be able to use data analysis and statistical reasoning to draw conclusions about the world. Two core statistical concepts for students to understand are the role of variability in measures and evaluating the effect of a variable. In the activity presented in this article, students investigate a scientific question…

The theory of "immaculate insulation" is prevalent among students. Research indicates that students often believe that some materials and objects, such as blankets or mittens, are intrinsically warm. Likewise, they believe that some objects and materials, such as metals, are cold. One effective way to gain insight into how students understand…

Continental margins are an important part of the ocean floor. They separate the land above sea level from the deep ocean basins below and occupy about 11% of Earth's surface. They are also economically important, as they harbor both mineral resources and some of the most valuable fisheries in the world. In this article students investigate North…

Having taught K-12 students and preservice teachers for almost 20 years, the author knows the problems that arise when students are asked to generate an investigation of their own design. Therefore, she developed some lessons that significantly increased the diversity and quality of the investigations students generated. This article describes…

Richard Louv's "Last Child in the Woods" (2008) added to a growing consensus to get children outside and experiencing nature. Using ideas from place-based education, the authors present a simple year-long project that brings science, nature, and other curriculum standards to life right in your school yard. With a focus on journaling, this project…

By focusing on one student, this case study illustrated ways that successful teachers invited success and may help other teachers create connections with students. This study chronicled one student's responses to her teachers' efforts to engage her during a teaching activity. Data from interviews, observations, and work samples showed how the…

As educators, we are always deciding what experiences we want to give students in order to achieve our goals of developing science process skills. One of the best ways of teaching about observation is described here. Using a hand lens and an illuminated pocket microscope, students observe an object at three different levels of…

Often children's questions are about the things they observe. The beauty of using children's questions about life to inspire discussions is that it invites children to work collectively toward a common goal. This article describes the process of using children's questions to facilitate great group time interactions. The process starts where the…

This article describes a twist on the basic "Science 101" investigation of having students observe a birthday candle before, during, and after burning. It engages students in exploring the attributes of a candle, introduces them to the concepts of empirical observation and investigation, and involves them in developing and conducting a burning…

While it is generally acknowledged that the first years of teaching are the most difficult, little is known about the development of subject matter specialists during this period. In order to add to the knowledge in this area, the present study explores the first year of 114 secondary science teachers as they participate in one of four different…

Fieldwork provides an opportunity to reinforce previous class-based learning and presents students with an opportunity to encounter new ideas and practice new skills. In the K-12 classroom, however, the rhetoric-reality gap between the declared need for fieldwork and doing fieldwork is striking. This project seeks to narrow the gap between…

Insects can be useful for investigations because they are numerous, relatively easy to find, and fascinating to students. Most elementary students have limited understandings of what exactly becomes of insects during the winter, often guessing that insects must "go to sleep" or "they just die." In this winter activity, students learn about insect…

The slime trails of snails lead the author's students to a better understanding of science as inquiry and the processes of science. During this five-day activity, students get up close and personal with one of her favorite creatures, the land snail. Students begin by observing the organism and recording their observations. After making initial…
