Many elementary teachers encounter science lessons with a hands-on component that requires very little engaged thinking by the students. The good news is that any teacher can create successful minds-on inquiry opportunities by adding key instructional strategies to a typical "cookbook" activity. The authors discuss some of these strategies using a…

Students love learning outdoors, but how do you ensure they are absorbing the science and gaining skills as they do so? The authors found a way--a fourth-grade classroom teacher, a gifted/science resource teacher, and a group of fourth graders--embarked on a yearlong study of birds and the plants they depend on. They used their school yard as the…

Students of all ages are fascinated by the ups, downs, loops, and twists of roller coaster rides! What they may not realize is that there is a lot of science involved in making a roller coaster work. This month's column puts students in the shoes of a roller coaster designer as they work in teams to create their own roller coasters. (Contains 1…

The author's most meaningful professional development (PD) experience was not a workshop or institute; nor did it result from a course or professional reading. Rather, it came in the form of Betsy--the second-grade teacher down the hall. This article describes the role of a mentor in professional development--and why everybody needs a Betsy!

Portugal has long been touted as a popular destination for savvy travelers, but now educators are touting it as something else--a professional development (PD) powerhouse for inquiry-based science! This article describes Portugal's ongoing efforts to reform its country's elementary science education program through a project known as the…

Electronic spreadsheets and online weather databases are excellent tools for making real-world comparisons of local, national, and global climate trends. The activities described in this article incorporate these tools to help familiarize students with electronic spreadsheets and how to use authentic data sets available from the internet to answer…

How many of our students come to the classroom with little background knowledge about the world around them and how things work? To help students develop conceptual understanding and explore the design process, the author brought the NASA "Engineering Design Challenges" program to his school district, redeveloped for elementary students. In this…

The "Needs of Seeds" formative assessment probe can be used to find out whether students recognize that seeds have needs both similar to and different from plants and other living organisms (Keeley, Eberle, and Tugel 2007). The probe reveals whether students overgeneralize the needs of seeds by assuming they have the same needs as the adult plants…

When learning about plants, elementary students are typically given set directions on how to plant seeds and make their plants grow. To enable their class of first-grade students to build their own knowledge and encourage constructivism, the authors decided to take this set of prescribe activities and make them more inquiry-based. In traditional…

There are many ways to share a collection of data and students' thinking about that data. Explaining the results of science inquiry is important--working scientists and amateurs both contribute information to the body of scientific knowledge. Students can collect data about an activity that is already happening in a classroom (e.g., the qualities…

Hopscotch, basketball, or hide-and-seek? Children have many choices at recess, and while making these choices they must consider and make trade-offs. The way they make these decisions is not that different from the thought processes engineers use when making design trade-offs. Engineers have to make trade-offs because a design that meets all…

Dinosaurs are one of those science topics that draw children in and teach them about concepts like measuring and using descriptive language. Learning about dinosaurs, although not hands-on like observing and recording caterpillar growth, develops critical thinking and introduces animal diversity and the relations between body form and function.…

As calls for science, technology, engineering, and mathematics (STEM) education at the elementary level become more vociferous, elementary teachers may be wondering whether engineering is meant for "all" students. However, the authors assert that engineering can be taught in inclusive environments. It may be especially empowering for those who…

Insects are fascinating creatures--especially when you and your students get up close and personal with them! To that end, the authors facilitated an inquiry-based investigation with an emphasis on identification of the different types of insects found in the school yard, their characteristics, their habitat, and what they eat, while engaging the…

Is light a ray, a wave, or a particle? Yes, yes, and yes. An article in this issue ("The Benefits of Scientific Modeling," p. 40) discusses the process of scientific modeling, and light is a great example of how modeling works. There are three viable models for light, each appropriate for different situations. The author will discuss the…
