Presents the Chem-E-Car competition in which students build a small car powered by a chemical reaction. Focuses on a controlled chemical reaction in which the car travels a required specific distance and stops. Requires participants to prepare poster presentations. (YDS)

Introduces land snails for use in inquiry-based science activities. Describes common characteristics and safety considerations while introducing students to land snails. Explains procedures for inquiry-based use of land snails in classrooms. (YDS)

Presents a simple everyday science activity concerning fingerprints for children and their families to do together. Includes a description and the procedure for the activity. (KHR)

Presents a scenario that helps students guess the site and purpose of a field trip while at the same time learning about matter and energy. (Author/KHR)

Given is a rationale for using science demonstrations. The development and characteristics of successful demonstrations are presented. An illustration is given in the area of microbiology. A rating sheet is included. (CW)

Presents an activity in which college chemistry students collaboratively identify chemical substances. (MKR)

Presents activities that use marine organisms with plant-like appearances to help students build classification skills and illustrate some of the less obvious differences between plants and animals. Compares mechanisms by which sessile plants and animals deal with common problems such as obtaining energy, defending themselves, successfully…

Presents activities that allow students in grades three to five to study sound by using children's tradebooks during exploration and experimentation. (JRH)

Presents hands-on science activities that help young children learn about the five senses and connect different aspects of the early childhood curriculum. (JRH)

Uses a diode array spectrometer to explain why blue objects appear red when viewed through the yellowish amber lens of "blue blocking" sunglasses. (JRH)

Teachers can use the movement of a tricycle's wheels to demonstrate ratios, and the movement of an automobile's wheels can be used to explain how a differential works. Additional concepts can be taught using trains, which negotiate turns through the flanges on their wheels, allowing the outer wheels to turn more slowly than the inner wheels…

Presents a project in which one science class, curious about large numbers, created one million marks on paper. Discusses other concrete representations of one million and other large numbers. (MKR)

Describes the use of light-emitting diodes (LED) instead of incandescent bulbs in experiments that generally use battery and bulbs to enable students to explore and understand fundamental electrical phenomena. Presents the following examples: Faraday's Law demonstration, conductors and insulators, and rectifying action of a diode. (JRH)

Presents activities to teach the concept of projectile motion to high school students using a spring-loaded dart gun, carbon paper, meterstick, ruler, white paper, tape, and a student's desk. (JRH)

Discusses the need for multicultural dialog as a meaningful exchange of ideas and emotions among stakeholders in a culturally diverse society. Presents strategies for incorporating multicultural dialog in specific science activities. (JRH)
