Full of color and sound, this problem-solving program features challenging searches for space ships. Its core function is to develop skills in indirect observation, hypothesis formation and testing, and use of coordinate grids.

Students locate a hidden space ship by firing “phasers” into a grid. Some beams bounce back, some rebound at angles, and some go straight through. Using the results, students determine the cloked ship’s size, geometric shape and location. Can be played by one or two students. Includes scoring and record-keeping options.
