1. EXT PARK -- DAY Ari and Elinor are sitting together working on a project we can't yet see. Sr. Tapir approaches them. SR. TAPIR Hey kids, what are you doing? We see that they are holding some folded paper. ELINOR We are making animals out of paper. SR. TAPIR Excellent! You know, this reminds me of a story I heard about the invention of paper. ARI What? Paper was INVENTED? SR. TAPIR Yes! And you'll never guess where the idea came from! Sr Tapir starts to strum his guitar and sings. We TRANSITION to a simpler style of animation that describes what he is singing. 2. INT CHINESE HOUSE -- DAY We see Cai Lun sitting at his desk, writing on sticks of bamboo. Ref: https: // en.wikipedia.org / wiki / Bamboo_and_wooden_slips SR. TAPIR Long, long ago and far, far away. People didn't have paper like we use today People would write on plants and sticks but it was rough and kind of thick Cai Lun has trouble, his drawings and letters look choppy. They say an inventor named Cai Lun [ spoken:TS-EYE LOON] wanted to write on something smooth He tosses his work out, looks frustrated. He decides to go for a walk. [Chorus] Sometimes the best ideas can be found When you go outside and search around While walking outside, he sees some wasps. Lun saw some wasps Make their nest by chewing up plants then getting them wet He watches them closely, gets an idea. Ref:https: // upload.wikimedia.org / wikipedia /commons/thumb/1/ 1a / Wasp_colony.jpg / 1024px-Wasp_colony.jpg When the nest dried it was very smooth Was this an idea he could use? He gathers pieces of plants from a mulberry bush or hemp plants. Ref:https: // cdn.shopify.com /s/files/1/1008/4432/products/ Black_Mulberry_3.jpg?v =1543343770 He chopped some plants and poured water in Squeezed it, dried it To make paper, smooth and thin! He makes paper. Ref: SEE PAGE 4. [Chorus] Sometimes the best ideas can be found When you go for a walk and search around He writes happily as a wasp flies in and lands next to his paper. 3. EXT PARK -- DAY ELINOR Wow, that's amazing! I didn't realize wasps made paper nests. Ari shows his handiwork: an origami wasp. ARI And check this out: a paper wasp! SR. TAPIR Haha ! Bravo! The end.

ELINOR WONDERS WHY EWW INTERSTITIAL 115: SENOR TAPIR Cai Lun and the invention of paper Written by Jorge Cham and Daniel Whiteson Follows: the “Paper Trail” in which kids learn how paper is made. Curriculum: the kids learn about how paper was invented by Cai Lun 2000 years ago, inspired by watching how paper wasps build their nests. ND3 . ( RTL Crosscutting concept ‘Structure and Function’): Understand that structures and materials in the natural world can be used or can inspire the engineering of structures with similar function in the designed world. Background info: Before paper, people wrote on papyrus, sticks, bone, bamboo, etc Papyrus is different from paper (despite the word "paper" being derived from "papyrus") because papyrus is woven, while paper has been disintegrated and reformed. Cai Lun (202 BCE-220 CE), a Chinese official working in the Imperial court during the Han Dynasty, is attributed with the invention of paper. However, earlier examples have been found, and he may have simply improved upon a known process. Legend states that he was inspired by the nests of paper wasps. Paper wasps are vespid wasps that gather fibers from dead wood and plant stems, which they mix with saliva, and use to construct water-resistant nests made of gray or brown papery material. Cai Lun’s paper was made using mulberry and other bast fibers along with fishnets, old rags, and hemp waste. The bark of the Paper Mulberry and Sandalwood were often used and highly valued during the period. His basic process of creating felted sheets of fiber suspended in water, then draining the water and allowing the fibers to dry in a thin matted sheet is still followed today.
