Students work in pairs or small groups to identify and categorize various objects. One student is blindfolded and the other student chooses five objects for his/her partner to identify. The blindfolded student has to describe and try to identify the object based solely on touch. Both students then record their data, describing the objects first as…

Many of today's popular sports are based around the use of a ball yet none are alike. In fact, they are all designed with specific characteristics in mind. In this activity, students investigate different balls' ability to bounce and represent the data they collect graphically. This activity uses a time frame of 100 minutes. (Author/SOE)

Depending upon the climate, the features of a house will be different to satisfy particular needs: hot, cold, windy, and/or rainy weather. In this activity, students investigate different types of roofs found on various houses in different environments throughout the world. Books and photos are used to provide information. Models of the houses are…

In this activity, students conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending, and torsion. In Part One, students play the role of molecules in a beam subject to various loading schemes. In Part Two, students break foam insulation blocks by applying…

After a discussion about what a parachute is and how it works, students create a parachute using different materials that they think will work best. They then test their designs, which is followed by a class discussion to highlight which paper material worked best. This activity requires a 60-minute time period for completion. (Author/SOE)

This brief discusses growing cells in a microgravity environment for grades 9-12. Students are provided with plans for building a classroom bioreactor that can then be used with the included activity on seed growth in a microgravity environment. Additional experimental ideas are also suggested along with a history and background on microgravity…

This CD-ROM contains four astronomy and space science learning center sites individually captured from the World Wide Web in January of 1999. Each site contains its own learning adventure full of facts, fun, music, beautiful images, movies, and excitement. Space science learning sites include: (1) Imagine the Universe! geared for ages 14 and up…

This study was conceived when it was observed that in the laboratory, with few exceptions, college freshmen chemistry students did not know how to make accurate measurements. Once the students were made aware of this, they easily learned how. From this experience and in the interest of breaking the cycle, it was decided to assess the ability of…

In every ecosystem, organisms rely on each other in unique relationships that ensure each other's survival. In Plant & Animal Interdependency, find out how plants and animals interact, cooperate and compete. All living things have basic needs and depend on other living things to meet those needs. Discover why the constant exchange of nutrients and…

This report describes a program for improving scientific literacy at the primary level. The target population consisted of pre-kindergarten and second grade students in an expanding suburban Midwestern community. An intervention which included the identification of scientific skills and their integration into the curriculum, student exposure to…

This paper describes a follow-up to a 1998 study that reexamined several aspects of elementary science students' achievement, attitudes, and journal writing in conjunction with an Alabama Hands-on Activity Science Program (HASP) grant utilizing the Full Option Science System (FOSS) kit. During the four weeks of the study, 20 fourth grade students…

Evaluate effects of an outdoor "hands-on," cooperative science laboratory on seventh- and eighth-grade students' environmental knowledge levels and science-processing skills. Participating students' scores on the Integrated Processes Skills Test were significantly higher than those of nonprogram students. Results support involving…

Provides rich description of the biological diversity found in a 30-mile section of Nebraska known as the "biological crossroads." Argues that the seven major associations of the Niobrara River valley provide a great classroom. Includes a complete listing of plant species. (DDR)

Presents a series of laboratory exercises designed to introduce students to a realistic experience in biological research that is feasible with large numbers of beginning biology majors. The exercises center on the study of alkaline phosphatase. (DDR)

Defines approaches to inquiry-based science teaching and describes many ways in which to conduct this kind of science instruction. Argues that with science reform underway, opportunities exist to transform classrooms into environments with active learners engaged in inquiry. (DDR)
