Students in the intermediate grades love to talk--but not necessarily about making sense of what they are learning. How do teachers design classrooms that cultivate productive discourse? How do they get out of the way and teach children to learn? First, let's give them something to talk about. Second, teachers need to teach them how to engage in…

The "Next Generation Science Standards" ("NGSS") have placed an emphasis on the incorporation of engineering practices into K-12 science instruction. This article details a sequence of physical science lessons that would be part of teaching matter in the second-grade classroom. The goals of these lessons are: (1) to be hands-on…

Cooking is a common experience in preschool classrooms, where teachers provide hands-on opportunities with ingredients in the process of following standard recipes. What sets this story apart is the way that the teacher supports the children in designing their own cookie recipe in an authentic way, using experimentation and manipulation of cookies…

In this article, second graders learn the basics of engineering through an exploration of magnetic levitation (maglev) technology. The author designed and taught the lessons to a class of 26 students enrolled in a month-long summer science program. The maglev lessons took place over three mornings (15 minutes for the first lesson and 40 minutes…

Many preschool classrooms explore plant growth. However, because many plants take a long time to grow, it is often hard to facilitate engagement in some practices (i.e., since change is typically not observable from one day to another, children often forget their prior predictions or cannot recall what plants looked like days or weeks earlier).…

After completing a science unit on transfer of energy, including how chemical energy from a battery is converted to electrical energy; electrical circuits; and transformation of energy into sound, light, or heat; the students in Mrs. Finlay's fourth-grade science class were challenged to use what they learned to solve a problem. The students…

The authors describes their experiences incorporating the virtual lab into a simple circuit lesson during an energy unit in a sixth-grade class. The lesson included a hands-on group experiment using wire, batteries, and light bulbs to make a circuit and an online simulation, using a virtual lab. Class discussions, student inquiries, and the study…

Teaching science with an inquiry-based approach can seem like an impossible challenge. However, it is achievable. One way to begin is by converting a cookbook-style lab (from the internet or a textbook) into an inquiry-based science experience. To convert a cookbook lab into an inquiry-based science experience, the authors propose the following…

This article introduces students to the world of digital microscopy. Looking at small objects through a digital microscope is like traveling through a foreign country for the first time. The experience is new, engaging, and exciting. A handheld digital microscope is an essential tool in a 21st century teacher's toolkit and the perfect tool to…

In order to demonstrate how plants remove water from the soil and release it to the atmosphere, students compared open- and closed-growing systems using drought-tolerant and higher water requirement plants. Then, students designed a drought-tolerant garden demonstrating what they had learned. Through this experience, students not only learned…

For several years, the author's fifth-grade students raised and observed plants, kept journals, and analyzed the functions of the parts of a plant. But this year, a near disaster taught her a lesson and increased the value of the activity for her students. Not only did students learn about plants, they now understand what a variable is and how…

Many recipes for elementary science activities suggest making carbon dioxide from baking soda and vinegar; however, they often do not give exact measurements of the ingredients. The author was able to turn this "drawback" into a plus by challenging her fifth-grade students to find the "ultimate fizz"--i.,e., "What amount of baking soda added to a…

What would your students say if you told them they could lift you off the ground using a block and a board? Using a simple machine, they'll find out they can, and they'll learn about work, energy, and motion in the process! In addition, this integrated lesson gives students the opportunity to investigate variables while practicing measurement…

Have you ever heard of a Maglev train? Who would be crazy enough to think that exploring how a high-tech train little known in the United States works with a group of fourth-grade students would yield understandings about the properties of magnetism, force and motion, and inquiry science? Fortunately, the authors--a college methods professor and…

In this article, the authors describe steps on how to develop a high-impact activity in which students build, test, and improve their own "coffee can" speakers to observe firsthand how loudspeakers work to convert electrical energy to sound. The activity is appropriate for students in grades three to six and lends itself best to students…
