Jacob, one of the Treehouse Detectives, has broken his foot. He is eager to get back into the treehouse and join his friends, but the cast on his foot prevents him from climbing the ladder. Using problem-based learning, the rest of the gang investigates the world of simple machines and physical science and "pulls" together to get everyone into the treehouse.

Follow the Treehouse Detectives in four video segments as they learn about simple machines, force, energy, work and the world of engineering to discover that "pulling" Jacob up into the treehouse is not as simple as they thought. Use the lessons and the questions in the videos to reinforce the concepts discussed in each segment.
