Using the movie Star Wars as inspiration, an activity is presented to introduce students to water's cohesiveness and how the surface tension of water can be disrupted. (MKR)

Presents a fun-filled activity in which students create the perfect Kool-Aid recipe. Incorporates chemistry, cooperative group skills, experimentation, and recording of results. (JRH)

Presents six middle school science notes for British science teachers. Some of these notes are: (1) fingerprints; (2) the floating magnet; and (3) the production of electricity using a lemon. (HM)

Presents a three-week interdisciplinary unit for starting the school year that focuses on the concept of flight. Enables students to acquire knowledge and develop process skills that they need later in the semester. (JRH)

Describes activities for starting the school year that allow students to begin learning laboratory skills and also gives them a chance to meet and interact with classmates in a relaxed atmosphere. (JRH)

This teaching guide introduces a relativity gyroscope experiment aiming to test two unverified predictions of Albert Einstein's general theory of relativity. An introduction to the theory includes the following sections: (1) "Spacetime, Curved Spacetime, and Frame-Dragging"; (2) "'Seeing' Spacetime with Gyroscopes"; (3)…

Describes a format for experiments where students not only conduct their own experiments but also become part of a model scientific community by writing research proposals, applying for grants, submitting their work to colleagues for scrutiny, participating in a symposium to present their findings, and creating a scientific journal to publish…

Objectives, materials needed, procedures, discussion questions, and follow-up activities are provided for five experiments. They include (1) testing for sugars; (2) comparing sugar to artificial sweeteners; (3) chewing gum scientifically; (4) soap making; and (5) making toothpaste. (JN)

Presents authentic assessment laboratory activities in which students measure the amount of sugar in bubble gum and test the lasting power of soap bubbles. Includes scoring rubrics. (MKR)

Describes an investigation in which students predict and verify the effect that the number of clicks of a toy copter gun has on the height that the copter will attain. Provides follow-up questions for the students. (MDH)

Students explore three-dimensional properties by creating red and green wall decorations related to Christmas. Students examine why images seem to vibrate when red and green pieces are small and close together. Instructions to conduct the activity and construct 3-D glasses are given. (MDH)

Suggests the use of simple testable problems to motivate middle school students to plan and carry out their own experiments, thus reinforcing integrated process skills. Lists several sample problems. (DS)

Describes an activity for helping students understand and use data tables. (PR)

Describes making a magnetic pendulum similar to those seen in novelty shops. Presents an open-ended activity and a more structured activity using this pendulum. (PR)

Summarizes comparisons of self-reported interest by gender and experimental condition for middle school students (n=101) who performed scientific experiments under conditions designed to vary across difficulty levels, social contexts, and scenarios of fantasy to realism. Findings indicate that boys were more attentive to aspects of experimental…
