The X-Cal Lab is a Science Computer Assisted Learning Lab. There are learning modules in Life Science, Earth Science, Physical Science, and Scientific Reasoning. Grades 2 - 5 work on modules with a partner in one area at a time.  They go through a lesson on the computer, a hands on experiment, complete work and record data in notebooks, and are assessed on their learning.

Grades K and 1 primarily work with Physical Science. Vocabulary and basic Science concepts are taught and practiced. Students use the Tac Tic building materials to build squares, cubes, balanced structures, simple cars, scooters, strollers, helecopters, airplaines, and more. They begin exploring with verbal instructions, and move to building cards with pictoral instructions. Problem solving is built into the lessons. They conduct simple experiments and collect and graph their data. Cooperation and teamwork is emphasised.
