Presents an activity to construct DNA and RNA models consisting of hundreds of nucleotide units. Provides students with insight into the composition and use of the DNA code. (JRH)

Modeling is an important step in the engineering process. In this activity, students create a model of an object of their choice using LEGOs (plastic building blocks), giving them skills and practice in techniques used by professionals. Students sketch as they build their objects. This activity facilitates a discussion on models and their…

Describes three models that provide a concrete experience of abstract concepts such as DNA replication, RNA synthesis, and protein synthesis. Explains their hands-on use and notes their advantages for teaching and learning. (JRH)

This booklet contains information and activities on the life cycle of stars. Materials can be adapted for grade 9 through grade 12 classrooms. Background information about star birth and life, black dwarfs, supernovae, white dwarfs, neutron stars, black holes, and the electromagnetic spectrum is included. The seven activities focus on star mass,…

This publication is a collection of 13 hands-on activities that focus on earth science-related activities and involve students in learning about growing crystals, tectonics, fossils, rock and minerals, modeling Ohio geology, geologic time, determining true north, and constructing scale-models of the Earth-moon system. Each activity contains…

Describes a project where students build a motorized car that can perform well in two distinctly different competitions: traveling 20 meters in the shortest time and pulling a 500-gram mass the farthest distance in 20 seconds. Enables students to apply physics principles to a real problem and to discover the importance of teamwork on large…

This document features descriptions of interactive learning models and presentations in environmental education concerning groundwater, geology, the environment, weather, water activities, and interactive games. Activities include: (1) GW-Standard; (2) GW-w/no Leaky Underground Storage Tank (No UST); (3) GW-Karst; (4) GW-Landfill Models--Standard…

Describes an activity that involves exploring a model cave made out of a two-person tent as a way to add science process to a thematic unit on bats and spiders. This multifunctional learning center provides students with a variety of hands-on experiences, helps students focus on observable things from nature, and emphasizes process skills. Lists…

This book is designed to help students understand the nature of scientific inquiry by involving them in doing science rather than merely reading about it. The content of the text emphasizes science process skills, mathematical skills, and the use of theories and models that are fundamental for learning the various science disciplines. The…

A program for remediating science illiteracy among primary level students is offered in this publication. A practicum was designed to address the lack of science teaching and student science experiences at the Marian Boyd School in Warrentown, North Carolina. Priorities included in-service education for teachers, a science laboratory for students,…

This book is designed to provide elementary science methods teachers with a vehicle that will allow them to help their own students become scientifically literate. Chapters include: (1) "On Understanding Science and Technology"; (2) "Why Teach Science to Children"; (3) "The Process Side of Science"; (4) "The Product Side of Science"; (5) ""Models…

This videotape recording (20 minutes) and print profile illustrate how educators are using technology to help students with disabilities succeed in science. In the first segment of the video, several elementary classrooms in Cambridge, Massachusetts, are visited where students with and without disabilities carry out inquiry-based science with the…

Noting that effective teaching models that emphasize critical thinking in mathematics and science are used less often in early childhood classrooms than in those for older students, this book provides early childhood educators with an explanation of teaching models that promote 3- to 8-year-olds critical thinking, problem solving, decision making,…
