Warm days, cold nights, melting snow-signs winter is waning and spring is nearing. Though winter may just be getting started in some areas, it's always fun to appreciate the good things about winter, including the special time at the end of winter in New England known as "sugaring time." The sap starts flowing in the sugar maples, and…

Presents a 4-week set of activities to engage 5th grade students in real-life applications of chemistry. Students solve a crime of theft through the use of mystery powders, chromatography, scientific analysis of cloth, and fingerprinting. (NB)

Discusses ideas for water rocket investigations. Highlights safety precautions that should be considered when using water rockets with soda bottles. (JRH)

Describes the experiences of children in a program that highlights the process of inquiry by allowing and encouraging children to raise questions, develop investigation strategies, formulate theories, and report findings in a variety of ways. Discusses the teacher's role in observing, respecting, and supporting children's work. (JRH)

Described is a third-grade science unit using feathers. Children use the feathers to learn about measurement, observation, and inference. Procedures and results are discussed. (CW)

Engaging fourth-grade students in hands-on science was easy when a container of mealworms arrived the second week of school. The author's naturally curious students immediately began asking questions, and soon they were eagerly investigating animal characteristics and behavior. But, the journey did not stop there. After students tested mealworms…

In this article, the author relates how a hands-on chemistry investigation provided her the inspiration to develop an effective safety lesson for her third grade chemistry class. She began the lesson by demonstrating the use of pH indicator paper to show that ordinary household (white) vinegar was an acid. With the students, she wondered aloud…

Describes an exploration of how light-up shoes work in which students become a community of scientists through debating, questioning, experimenting, formulating ideas, researching, collaborating, and communicating their understandings. (JRH)

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…

Proposes the use of metal cans to create science experiments that motivate students to investigate the scientific concepts of electricity, magnetism, heat, inertia, and sound transmission. Describes several experiments using cans in which students explore the properties of metal. (MDH)

Describes the EQUALS Family Science Program, a national program designed to promote equity in mathematics, science, and technology, in which the goal is to make children and parents more scientifically literate by doing science investigations together. Presents activities that teachers can use to promote scientific literacy and cultural diversity.…

Through an interactive partnership, fifth-grade students collected data on plants and joined an active scientific community of working scientists. This Web-based Integrated Science Environment (WISE) project involved asking questions about plants, growing plants in the classroom, and discussing their data with scientists online. (Contains 5…

The Experimental Reflection Portal, or "XRePort" is an online system that pairs students and teachers from different schools and allows them to "talk" about their common science investigations. In this way, students communicate their science knowledge "and" experience firsthand the benefits of the collaborative nature…
