In recent years, the integration of science and mathematics has become popular among educators because of its potential benefits for student learning. The purpose of this study is to introduce a two-day interdisciplinary lesson that brings science and mathematics concepts together, actively engaging students in working with percentages of the…

More than 60 years have passed since the work of Rosalind Franklin, James Watson, and Francis Crick led to the discovery of the 3D-DNA double-helix structure. Nowadays, due to the simple and elegant architecture of its double helix, the structure of DNA is widely known. The biological role of the DNA molecule (e.g., genetic information), however,…

Elementary, middle-level, and high school science teachers commonly find their students have misconceptions about heat and temperature. Unfortunately, student misconceptions are difficult to modify or change and can prevent students from learning the accurate scientific explanation. In order to improve our students' understanding of heat and…

This investigation-based lesson is geared toward third through fifth grade students. The lesson presented in this article was the first of three lessons designed and taught by us for our first preservice teaching course. UTeach is a teacher preparation program for undergraduate STEM majors, which originated at the University of Austin, Texas. The…

In this article, we describe a fourth-grade inquiry unit on soil. The unit was designed and taught by preservice elementary teachers as part of a university science methods course. Using a student-driven inquiry approach to designing curriculum, the unit engaged fourth graders in learning about the physical properties soil, erosion, worms, and…

This standards-based science lesson introduces young learners to scientific inquiry and critical thinking by using activities to demonstrate three phases of matter (solid, liquid, and gas). By learning about the states of matter through a 5E instructional approach, students are encouraged to observe changes in the states of matter and to discuss…

This article describes the use of project-based instruction in activities and labs intended to develop higher-order thinking skills with high school students and pre-service teachers through the use of soap making.

Scientific modeling along with hands-on inquiry can lead to a deeper understanding of scientific concepts among students in upper elementary grades. Even though scientific modeling involves abstract-thinking processes, can students in younger elementary grades successfully participate in scientific modeling? Scientific modeling, like all other…

This effective technique has third- and fourth-grade students explore potential and kinetic energy and explain their discoveries. Students investigate what it takes to make a paint can roll forward and come right back, without seeing inside. Students experience science as an inquiry and develop their critical thinking skills. Students can also…

In contemporary science education, the trend is to engage students in hands-on activities in which they must manipulate equipment and gather data in an effort to answer questions. Hands-on experiences may turn out to be meaningless unless the experiences are well designed, planned, and focused so that students are guided to construct accurate…

To successfully generate student excitement in science, teachers need to be flexible regarding their curriculums. Students also need to be open to novel, hands-on experiences. This article describes a student teacher (ST) who taught a science unit on "Our Environment." She had already prepared her lesson and unit thoroughly but she changed the…

Science requires active learning--it is something that children do, rather than something that is done to them. The learning process involves students' thinking and doing to develop higher-order thinking skills, strengthen their reading and mathematical skills, and attain scientific knowledge. In the elementary grades, children learn biological…
