Describes two experiments in physics, using the same inexpensive apparatus, that may be performed as projects by high ability secondary science students. (JR)

Briefly described are 25 "hands on" classroom activities which require live, freshly killed, or preserved grasshoppers. Topics of activities include predator-prey relationships, feeding habits, locomotion, dissection, anatomy, and population estimates. (DS)

A multidiscovery, open-ended, sciencing experience appears to have implemented nearly the full spectrum of cognitive, affective, and psychomotor objective domains.'' (Author/DF)

Describes student activities with mercuric oxide and mercury that help them to form models of the solar system and its creation. (JR)

Describes a few activities designed to give students an opportunity to investigate man-made meteorites.'' (Author/DF)

Presented is an activity in which students use a microscope to do a forensic hair comparative study and a medullary classification. Mounting methods, medulla types, hair photographs, and activities are described. (DS)

Experiences and experiments with mirrors will spark pupils' imaginations while providing insights into the nature and behavior of light. (Author/DF)

Several activities related to color are discussed. These include placing different colors on a disk which, while spinning, appears to be white. Also discusses complementary and primary colors. (JN)

Describes a lab investigation designed to introduce students to soil compaction and help them to learn to design and adapt procedures that scientists use when they plan and conduct controlled investigations. Provided are objectives, a list of materials, procedures, and a sample student handout. (CW)

The use of 10cc. syringes in high school chemistry experiments can reduce the expense of equipment and lead to imaginative experimental designs. Describes the equipment and experimental procedures for four experiments utilizing syringes. (JR)
