This column provides ideas and techniques to enhance your science teaching. This month's issue discusses how children think about the small-particle model of matter. What Richard Feynman referred to as the "atomic hypothesis" is perhaps more familiar to us as the small-particle model of matter. In its most basic form, the model states…

The authors share a sequence of lessons that teachers thought were especially useful to produce effective science discourse and promote student understanding. The first lessons teach social and emotional skills. The later lessons focus on energy sources and systems, requiring students to apply their social and emotional skills to conversations…

Using cross-grade peer mentoring as an integral component to field trip experiences can help educators realize the learning potential of nature-based experiences. When young students are paired with older students, Socratic peer dialogue deepens interest, investment, and ultimately ownership of new learning. Using peer-supported inquiry…

Inspired by a song to be sung by her daughter's first-grade class in an upcoming musical, a parent volunteer teacher used fireflies as the focus of a science lesson to build on the children's interest and experiences. She developed a 5E lesson (Bybee et al. 2006) using the backwards-design approach (Wiggins and McTighe 2005) to ensure meaningful…

This article describes a group of second and third graders who began the school year 83% below reading proficiency. On surveys given at the beginning of the year, parents/guardians stated reading was the biggest concern for their child, and students stated they enjoyed hands-on activities, especially during science. To increase comprehension and…

In their role as careful observers of nature, citizen scientists are helping to "answer the most challenging ecological and environmental questions, addressing issues that affect everyday lives" (McKinley et al. 2015). They help answer these questions by providing scientists with a large pool of data that can be analyzed (National…

The mechanics by which unique individuals are built from the instructions encoded in DNA is too advanced for elementary-age children. However, students can easily understand that organisms have observable traits and that each individual has a unique combination of traits, ideas that are included in the "Next Generation Science Standards"…

Insects are extremely important for maintaining the natural environment, performing such essential ecosystem services as decomposition, dung burial, and soil aeration, as well as providing food for other wildlife. Insects are also important for human interests such as crop pollination. Though the advantages of using insects as teaching tools are…

This article describes a force and motion unit that spanned four weeks (50 minutes a day) in a fifth-grade classroom. The inquiry-based learning progression mirrors Piaget's Theory of Cognitive Development (1952) because it allowed students to manipulate materials and ideas as they actively constructed and reconstructed their knowledge of motion…

On Monday, August 21, 2017 there will be a Total Solar Eclipse. This will be the first time the Moon's umbra has touched the continental United States since 1979 and the first totality to span the country coast-to-coast since 1918. From within parts of Oregon and through 14 states to South Carolina, the Moon will completely hide the Sun for a few…

The authors describe how grade 4 students carried out an investigation about growing cucumbers (members of the curcurbit or gourd family) where they read information sources about seed variety; germinated seeds under different conditions; measured and partitioned growing spaces; collected and analyzed data on germination, true leaf growth, and…

Units on static electricity and electrical charges are always a third-grade favorite, with students finding the inquiry and hands-on activities, well, electrifying. However, teachers planning a unit on static electricity may find it difficult to navigate around latex bans. While latex allergy is a serious issue, removing balloons from the…

This article describes one participating teacher's reflections on the generalizable strategies and structures from the professional development (PD) sessions that enabled her sensemaking, and how she translated these generalizations into her own second-grade classroom. Readers will be able to make their own useful generalizations from these…

This column provides ideas and techniques to enhance your science teaching. This month's issue discusses using the 5E learning cycle to create coherent storylines. The 5E learning cycle provides an important framework to help teachers organize activities. To realize the full potential of the 5E framework for student learning, lessons must also…

Having written columns dealing with science fairs before, Bill Robertson notes that it's been a long time since he has tackled the subject of what passes for a "science fair" in schools these days. Because science fairs have changed over the years, Robertson revisits the topic and explains the scientific method. The main focus of the…
