Pictures are Worth Thousands of Words, Simulations are Worth Millions! Science and math topics come to life, and student depth of understanding soars when using online simulations to introduce, develop and expand conceptual understanding. In classrooms that resemble mathematics and science laboratories, students manipulate key variables, generate and test hypotheses, and engage in extensive “what-if†experimentation. Come experiment with seasons, genetics, density, gravity, fractions, functions, slope and more. Simulate them!
