Pendulums: Grades 4-9 - Paperback
Details
by Peg Marson (Illustrator), Ronald Jay Marson (Author)
Time pendulums, count cycles, measure lengths, graph data, predict frequency, calculate ratios, and even discover the square root of two. Couple pendulums with a rubber band to watch the energy flow back and forth. Join four pendulums with a raft of heavy books and watch the complex harmonic motion draw a seashell pattern. Great science, great math, great art, all done with simple materials.
