Bentley's Bones: The Natural History Museum is receiving its first exhibit, a full sized Tyrannosaurus rex skeleton, and Bob and the team are finishing off the new extension. However, Leo discovers that Mr. Bentley provided the incorrect dimensions of the doors for the new extension. The dinosaur skeleton will not fit through them! Per Lofty's suggestion, the team dismantles the skeleton. They have difficulty reassembling it, but the photo on Leo's phone acts as an adequate guide and the team is able to successfully complete the job. Learning Goals: To explore size comparisons. To explore following a plan/guide for building or rebuilding. To appreciate the consequences of one's decisions and actions. Bear's Mountain: The zoo is preparing for a bear's arrival and needs Bob and the team to finish building the new bear enclosure. Bob plans a three-tiered natural habitat that resembles a rocky mountain, but Scoop is thinking bigger. With the other machines to help him, Scoop builds the structure higher--too high--and it collapses. Bob considers Scoop's attempt and redesigns the mountain to be four levels. The crate arrives and two bears, a mother and her cub, are set to enjoy their new enclosure. Learning Goals: To explore animal habitats and animal needs. To learn about taking apologizing and taking responsibility for one's actions. To recognize the value of learning from mistakes. To understand creative problem solving.
