This book contains classroom experiments designed to promote group skills. Each lesson has 4 parts: a 3-minute set-up; 5-minute warm-up, 25-minute experiment, and 5-minute clean-up. During each part, each member of the group is responsible for performing a specific task. Included are 34 labs that cover a range of topics: observations, physical…

Presents a six-step problem-solving process which the author has used to present creative science investigations to fourth, fifth, and sixth graders. (Author/SJL)

Presents a laboratory exercise in which students test the pH of different substances, study the effect of a buffer on acidic solutions by comparing the behavior of buffered and unbuffered solutions upon the addition of acid, and compare common over-the-counter antacid remedies. (MKR)

Presents an activity that is part of the National Science and Technology Week (NSTW) 1993. Students apply principles of biomechanics to find the most effective techniques for performing a standing broad jump and use that analysis to improve their own jumping. Instructions include procedures, materials needed, and possible extensions to the…

For many summers the Radiation Science and Engineering Center at Pennsylvania State University has been the site of a Nuclear Concepts and Technological Issues Institute for secondary school science teachers. As a culminating activity of the institute teachers develop lesson plans, laboratory experiments, demonstrations, or other activities and…

In a hands-on experiment to illustrate the concept of cycles in ecology, students use the Winogradsky column to explore the operation of the sulfur cycle and the interrelatedness of organisms in an environment. Lesson plans include materials needed and class procedures. (MDH)

Presents 2 activities for students aged 8-12 in which students determine (1) whether or not earthworms can see white light; and (2) how an earthworm moves without legs. (MDH)

Eight steps are outlined for presenting a combined science/language experience unit to primary students, in which the children observe and discuss a phenomenon and dictate a group report. Sample projects with fossils, magnets, and air pressure are described. (SJL)

Presents a sequence of activities designed to allow eighth grade students to deal with one of the fundamental relationships that govern energy distribution. Activities guide students to measure light bulb brightness, discover the inverse square law, compare light bulb light to candle light, and measure sun brightness. (two references) (MCO)

Outlines the stages of a cell biology "pulse-chase" experiment in which the students apply autoradiography techniques to learn about the concept of the cell cycle. Includes (1) seed germination and plant growth; (2) radioactive labeling and fixation of root tips; (3) feulgen staining of root tips; (4) preparation of autoradiograms; and…

This packet contains two science learning activities that can be used in agricultural education courses. The first activity, "Using Ethanol as a Solvent," is intended to help students describe the characteristics of a solvent, to enhance student observational skills dealing with physical changes, and to demonstrate the acid or alkaline…

The three units of study presented are designed to promote space-related learning opportunities for gifted students and were prepared by recipients of the Scobee curriculum awards. In "Galactic Colonization for Our Future Astronauts" (Jacqueline Shimonauff), elementary-level students simulate a space experience in which a ship carries materials…

Presents a class activity in which students use trigonometry to calculate the height attained by a water rocket. Provides a lesson plan that includes a list of materials needed, procedures to carry out the experiment, suggestions to extend the activity, and a reproducible worksheet for the students to register their calculations. (MDH)

This packet contains three science learning activities that can be used in agricultural education courses. The activities cover these topics: (1) determining the effects of soil particle size on capillary action; (2) measuring levels of eroded soil particles in streams; and (3) determining the effects of soil cover and texture on surface erosion.…

This course of study is aligned with the California State Science Framework and provides students the chemistry content needed to become scientifically literate and prepared for post-secondary science education. The course of study is divided into four sections. The first section provides an overview of the course and includes a course…
