See inside. Understand more.
Crawford Group Holdings launched How It Works on October 22, 2026, with 50 free interactive explanations. The platform helps visitors understand the parts, processes, and connections behind familiar things, from bicycle gears and hydraulic brakes to generators, GPS, and the heart.
The collection spans five subject areas. Each experience has its own address, so a learner can go directly to a topic or return to it later. Access does not require an account.
Watch, try, and explore the explanation
Show me follows the mechanism through guided stages. Visitors can play the explanation, pause, restart, or move one step at a time. Let me try offers an activity built around the specific mechanism, making the relationship between a choice and its outcome easier to see.
Explain more adds terminology, common misconceptions, source links, and model limitations. Start with a familiar system, follow one complete cycle, then change an activity setting and compare the explanation.
Two paths into free learning
How It Works explains the mechanism. Its companion What If lets visitors explore how outcomes change when conditions change. Direct links in the learning menus connect the two platforms, and the CGH corporate menu brings them together under Free Learning.
The diagrams are simplified teaching models. Some activities use predefined states or illustrative calculations, and the pages explain those limits. The launch does not claim independent scientific calibration or accessibility certification.
