Introduces a hands-on science project in which groups of students design machines. Recommends dividing the class into groups and provides a rubric for student assessment. (YDS)

Presents hands on science activities using toys on the topics of average speed, acceleration, wavelength, and bouncing balls. (YDS)

Describes an activity in which the story of "Frosty the Snowman" is reviewed and students are challenged to come up with ways to save Frosty. In cooperative groups, students brainstorm, share ideas, and write a prelaboratory report. After the approval of plans by the teacher students construct the snowmen and begin the three-day experiment. (DDR)

Presents an activity on the study, collection, and analysis of snow. Provides students with opportunities to conduct fieldwork in a collaborative team fashion and develop skills in formulating and testing hypotheses. (DDR)

Presents a set of hands-on electrostatics experiments in the form of an activity guide and worksheet through which students discover the different types of electric charge, Coulomb's Law, induced charge separation, and grounding. (DDR)

Announces the theme for National Science and Technology Week (NSTW) 1998 and offers a rationale for the choice of the topic of polar connections. Suggests that the poles offer a glimpse of science as high adventure. The poles are often seen as pristine, nearly lablike environments that provide a platform for animal studies. (DDR)

Introduces a group activity in which students build a catapult. Includes a list of materials required for catapult construction and directions for testing. (YDS)

Presents an activity on the electrostatic phenomenon known as induction. Reviews the principles illustrated by each of the activities described in this series. (DDR)

Model rocketry is one of the best ways to get students interested in the physical sciences. Following safety guidelines, rocketry can really turn students on to science and also help them understand the applications of theories and scientific principles (Newton's laws of motion, force, mass, projectile motion, etc.) they are learning. The study…

Describes a guided inquiry activity that addresses the law of reflection. Laboratory experiment is included. (DKM)

Presents a modification of a procedure for making and launching hot air balloons made out of garbage bags. Student instructions for balloon construction, launching instructions, and scale diagrams are included. (DDR)

Describes an activity that focuses on the question: How hard is it to break spaghetti noodles? Students design their own experiment that involves hanging a cup of pennies from a piece of spaghetti by a paper clip and investigate how many pennies the noodle can support without breaking. (DDR)

Presents a unit on motion that allows students to apply what they learn from doing hands-on, minds-on activities, a key component of the National Science Education Standards. Also includes examples of the assessment instrument. (DDR)

Presents worksheet activities that enable students to explore the concept of electrostatic induction and learn the meaning of grounding. Students build two classic devices, the electrophorus and the leaf electroscope. (DDR)

Provides construction and operation details for a tornado machine. Includes suggestions for investigations and information about tornado warnings. (DDR)
