Economy Force Table
Make multiple trials of force/vector problems easy. Hang the force lines over the table edge, establish a mechanical equilibrium in the center, and read the force angles and masses to mathematically verifiy equilibrium. Reverse the process for lab practical exams. Includes top markings in 1o increments, four weight hangers with glass guides, center post pin, cord, 20 equal masses and instructions.

Marble Down—
Centripetal Force—
Flinn STEM Design ChallengeTM
Student Laboratory Kit
This activity familiarizes students with engineer- ing design. In the design process, students ask questions, define problems, plan, create, test, evaluate and more! They investigate variables to determine how each affects the marble’s speed on a rubber band track. Student engagement increases as concepts from the introductory activity are applied to build a marble maze with the longest run time.
AP8315 | $74.95
Demonstrate the relationship between angular velocity and centripetal accelera- tion. The low cost and simple construction of the centripetal force apparatus make it a must for every classroom. The experiment uses the weight of 20 washers hanging from one end of a nylon thread to balance the pull of a rubber stopper swinging overhead. Complete instructions provided.

Mousetrap Cars—Super Value Guided-Inquiry Kit
Integrate content and reasoning through science and engineering practices as students investigate the parts of a mousetrap car (wheel and hub diameter, length of lever arm) to determine how each affects its performance. Students analyze their quantitative data to design a solution and develop communication skills presenting their evidence-based designs. Kit complete for six student groups.

Second Law of Motion Apparatus
An ingenious and entertaining way to demonstrate Newton’s second law of motion. Have students predict which ball will hit the floor first. Then have them close their eyes and listen. Much to their surprise, both balls hit the floor at precisely the same instant! This is amazing since one ball falls straight down while the other is propelled horizontally first. The spring-loaded release arm ensures simultaneous release of the balls for predictable and repeatable results.
