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…

In a remarkably brief period of time, humans have developed technology that allows space travel to become a reality. Rockets have been built, energy systems designed, and planetary forces understood. In the activities described in this article, students investigate space travel by designing their own rockets and manipulating variables to determine…

To capture students' excitement and engage their interest in rocketships and visiting planets in the solar system, the author designed lessons that give students the opportunity to experience the joys and challenges of developing straw rockets, and then observing which design can travel the longest distance. The lessons are appropriate for…

Oranges, flying disks, pool noodles, and polyvinyl chloride (PVC) pipe may seem like items discarded after a Rube Goldberg experiment, but in fact, these objects were used in teaching science, technology, engineering, and math (STEM). This article describes a project in which The Center of Ocean Sciences Education Excellence SouthEast (COSEE SE)…

Describes how to construct a safe, inexpensive rocket for use with young children. (MKR)

Illustrates the concept of phototropism and the development of root systems using a classroom-constructed clinostat. Provides instructions to construct the clinostat and tips to promote plant growth. (MDH)

Presents a teacher-made instructional material that can be used to help students understand and retain the concepts of magnet and magnetic field. Doughnut-shaped magnets levitate above each other when placed over a post with like poles facing each other. Instructions are provided to make the device. (MDH)

Describes the construction of a variety of inexpensive, escape-proof, and safe insect homes--each complete with window, ventilation screen, and cover--so students can observe firsthand the intriguing world of insects. (PR)
