In this essay from a teacher in Argentina, Valeria Vincent describes how she employed Multiple Literacies in Project-based Learning (MLPBL) (Krajcik, Palincsar, and Miller 2015). ML-PBL, an open education free resource, has three design principles that support teacher and student learning and satisfaction. ML-PBL builds on teacher ingenuity and…

At a time when changes in standards and curriculum compound the pressures of fifth-grade state testing, the authors wanted to find an engaging way to involve students in authentic science and engineering. Rather than put their efforts into a traditional science fair that would inevitably lead to inequitable input by parents and students alike,…

This article describes a second grade science enrichment unit with a focus on human impact, both positive and negative, on the living and nonliving components of the local watershed. Investigating the local watershed gave the unit a personal and pragmatic connection to students' lives because they depend on the local watershed for what they need…

How can an engineer design a bird feeder that attracts many birds? This question resulted from kindergarten students' observations of the bird feeders in their school's bird sanctuary. The challenging question is the heart of project-based learning (PBL), a teaching strategy in which students tackle real-world problems and design projects to solve…

It is common to see word walls displaying the vocabulary that students have learned in class. Word walls serve as visual scaffolds and are a classroom strategy used to reinforce reading and language arts instruction. Research shows a strong relationship between student word knowledge and academic achievement (Stahl and Fairbanks 1986). As a…

Engaging elementary students in evidence-based reasoning is an essential aspect of science and engineering education. Evidence-based reasoning involves students making claims (i.e., answers to questions, or solutions to problems), providing evidence to support those claims, and articulating their reasoning to connect the evidence to the claim. In…

Can students build a house that is cost effective and strong enough to survive strong winds, heavy rains, and earthquakes? First graders in Ms. Peter's classroom worked like engineers to answer this question. They participated in a design challenge that required them to plan like engineers and build strong and cost-effective houses that would fit…

Presented is an idea for combining popular hobby interest with the big ideas of science. Suggestions are presented and detailed directions given for terrarium building. (EB)

Describes a science fair designed as a teaching tool rather than as a contest. Includes the fair's objectives and lists of possible science fair topics. Topics are organized under these areas: human body; animals and plants; earth and universe; physical principles, machines, and technology; and miscellaneous topics. (JN)

Relates how a classroom can support and house a mini-museum of natural science. Describes the various types of exhibits and the range of activities that can be developed from them. Explains student involvement in exhibit design and use. (ML)

Commercial advertisements in publications can suggest numerous topics for student investigations. Students can gain research experience by devising experiments for testing products. (PS)

In the activity described, elementary school children each adopt a tree and make monthly observations which are recorded in their log books. (JR)

To develop scientific literacy in today's global era, however, it is important that students learn about interactions within the Earth's systems worldwide. A unit exploring El Nino and La Nina-phenomena that can result in extreme weather events in locations all around the world-can help bridge this gap and broaden students awareness of global…

For the sake of grade school entrants in particular, nonexperimental science fair projects should be encouraged and accepted for science fairs. Support for this approach is given along with several suggestions for projects. Guidelines for judging nonexperimental projects are also included. (DH)
