Name of 90s children's PC game... scientific, educational game? - 90s educational games

I only know that we tried to move through the gears, to cross the closed doors to solve puzzles to open doors. Puzzles with scientific and technical matters .. so that the disc drag to the right place or a power outlet to run a light bulb. It was the third person style platform games. I think they would consider parts of the game, and finally, he used the parts that came together to create a vehicle for a career? Something like that! Please help! Thank you!
