Student worksheets included with every lab! Force & Motion Two-Dimensional Motion — Horizontal Projectile Lab Challenge students to predict the range of a projectile launched from the ramp! Accurate measurements make it possible! Free Fall and Acceleration — Gravity Lab Students can measure the acceleration due to gravity in three different ways with these two simple pieces. Students can achieve increasing levels of accuracy by measuring acceleration with a stopwatch, photogate, and Go! Motion sensor. 4 5 Kit includes one 2" ball, one Picket Fence, and complete instructions. Also required but not included: Stopwatch, Timer, Photogate. Recommended: Go! Motion sensor. P4-1380 Gravity Lab $12 Marbles can be released from any point on the ramp, and the launch point can be adjusted to any height above the table or floor. An integrated bubble level assures you that the launch is truly horizontal. Mount a photogate (or two for pinpoint accuracy) to the lower end, and measure the launch velocity. Use that velocity to predict the range, and place a can at the predicted point. Release the marble again, and hit the target! Includes Ramp and one 3/4" steel marble. Required but not included: Workshop Stand, Timer and Photogates. “Seatbelt” keeps masses securely fastened to car. P4-1390 Horizontal Projectile Lab $89 es gat o t Pho Workshop Stand Photogate clamps right to the side of the ramp. No extra stands required. Ramp Simple Harmonic Motion, Conservation of Energy — The Pendulum A perfect example of how new technology can be used to enhance traditional labs. First, experiment with different weights, lengths, and amplitudes to find out which affects the period. Then use a photogate to measure the bob’s maximum speed and a Go! Motion sensor to see how the speed changes throughout the swing. We’ve included a whiteboard where students can record the bob’s vertical displacement and predict the maximum velocity using conservation of energy. Includes pendulum face, string, bob, grid, and bolts. 6 Requires Workshop Stand, Timer and Photogates. P4-1700 Pendulum Lab $59 arborsci.com Digital Timer and Photogates The Arbor Scientific Timer lets students focus on learning the science at hand instead of mastering complicated technology. They will be collecting data within seconds of turning it on, in one of six different timing modes. Times can be collected at one photogate at a time, both gates or get the time between the photogates. 8 Visit us online to download Motion, Forces, Newton’s a free sample lesson from Laws — Car & Ramp the Physics Workshop Experiment with distance, time, velocity and Teacher’s Guide. acceleration, Newton’s laws, and simple machines. The 120 cm ramp attaches to the Workshop Stand at angles up to 65° . A pulley at the top allows students to measure force with a spring scale or force sensor. Attach photogates to the side and capture data points during the car’s trip, or place a Go! Motion sensor at the bottom of the ramp. The car has low-friction ball bearing wheels and room for added mass. 7 PC-7500 Digital Timer and Photogates Go!® Motion sensor Mounting Rods (pair) $229 $99 $8 Requires Workshop Stand, Hooked Masses, Timer and Photogates.
