EXT CAMPSITE -- DAY It's a sunny afternoon in the forest, and ARI, ELINOR and OLIVE are on a camping trip with Ari's family. We open as Elinor and Olive are finishing setting up their tents at a campsite (we can reuse the ones from the Light The Way episode). ELINOR There. All done. OLIVE Me too. How's your tent going, Ari? We pan over to Ari as he puts on the finishing touches on his tent. ARI All set! I think I'm finally getting the hang of camping. At that moment, we hear a bit of chaotic noise. Next to Ari, we see MR. BAT having some trouble setting up the family tent from inside <SFX: OOF / URK /HMM>. ARI (O.S.) (CONT'D) Uh, Dad, do you need help? Mr. Bat's head emerges from the tent, which is a jumbled mess. MR. BAT Thanks, Ari. That would be great. I haven't quite figured this out yet. The tent collapses around him. MIRI (Ari's baby sister), in MRS. BAT's arms, <SFX: GIGGLES>. The kids go over and hold down the corners of the tent while Mr. Bat continues to try to prop up the poles. MR. BAT (CONT'D) Thanks, kids. You know, at home we bats usually sleep hanging from the ceiling, so setting up tents and sleeping on the ground is all very new to us. As he talks, we see a THOUGHT BUBBLE of Mr. and Mrs. Bat sleeping upside down at their house. ELINOR That's what makes camping an adventure! MR. BAT You're exactly right, Elinor. Camping is all about being out in Nature and doing things differently. ARI And, let's not forget, having tasty camping snacks! OLIVE (giggles) Ari liking snacks is not very different. They all <SFX: LAUGH>. ELINOR My favorite part of camping is to go exploring in a new place, so I can see and hear new things. MR. BAT Well, we'll go for a nice walk soon, just as soon as I (struggling with tent pole) finish... setting... up... this... tent! The tent collapses again. Miri <SFX: GIGGLES> again. MR. BAT (CONT'D) (poking his head out) I think we know what Miri's favorite part of camping is: watching her dad try to set up the tent. Miri continues to <SFX: GIGGLE> and the kids join in. MRS. BAT (setting Miri down and rolling up her sleeves) Oh dear. Why don't you kids go play? I'll help Mr. Bat. The kids look at each other smiling and run off. ARI Thanks, Mom! EXT. FIELD -- DAY The kids walk a few feet away to a field (within eyesight of the camp) as they talk about what to do. OLIVE What should we do? ELINOR I just learned a really fun game, want to play it? Ari and Olive are game <SFX: WALLA YEAH!/SURE!>. ELINOR (CONT'D) It's called "Marco Polo." It's kind of like tag, but you play with your eyes closed. ARI With your eyes closed? Elinor pulls out a blindfold she brought along. ELINOR Yeah, here's how it works. If you're "it" you wear this blindfold so you can't see. OLIVE Wait... if you can't see, how do you tag anyone else? Olive pantomimes randomly tagging the air. ELINOR That's the fun part. If I'm "it" and I say " marco ", then everyone else has to say "polo." ARI Oh, I get it. So when you HEAR them say "polo", you can tell where they are, without SEEING them. OLIVE Sounds fun. Can I be "It" first? Elinor puts the blindfold on Olive. From Olive's POV , we see the blindfold go over her eyes. Everything is dark for a moment. Back to the outside view, Olive has her arms out in front of her. OLIVE (CONT'D) Wow, I can't see anything! Ari does a silly dance. [Note for animation: make sure the kids' acting is respectful, and not seen as taunting] ARI Did you see that? Olive shakes her head <SFX: WALLA NOPE/UH-UH>. Ari does a sillier dance. ARI (CONT'D) How about that? Olive shakes her head again <SFX: WALLA NOTHING/NO>. ARI (CONT'D) Wow, that's a good blindfold. ELINOR Ok , but can you HEAR us? Olive points to Elinor. OLIVE Yes! I can HEAR that you are right there. Ari is flying off to the side. ARI Ooh ! Can you hear me? Olive perks her ears up and points to Ari with her trunk. OLIVE Yes! I can hear you way up there! Hey, no flying! Ari lands. They all <SFX: GIGGLE>. ARI Cool, I like this game. ELINOR Let's play! Elinor and Ari walk to new places. Olive takes a few tentative steps, and walks around with her hands (and trunk) in front of her. OLIVE Ok , here I come! Marco! ELINOR/ARI Polo! Olive moves in the direction of Ari, who scrambles out of the way. Ari and Elinor <SFX: GIGGLE>. The kids play for a few beats, calling and responding <SFX: MARCO! POLO!>. Olive moves towards Elinor, who dodges, and Olive grabs a bush instead. OLIVE Got you! But you don't feel like Elinor... (lifting the blindfold) Oops, it's a bush! They all <SFX: LAUGH>. OLIVE (CONT'D) Wow, that's hard! ARI Oooh , I want to try! Olive hands him the blindfold. He ties it on as the girls find their places. ARI (CONT'D) Get ready, here I come. The girls smile and suppress their <SFX: GIGGLES> as Ari holds his arms out. As he starts walking, he moves much more confidently than Olive did. ARI (CONT'D) Let's see... where are you... Got you! He walks straight to Elinor and tags her. [Note for animation: show Ari smiling when he walks, with his mouth open and making barely perceptible vocalization movements] OLIVE Wow! You didn't even say Marco. ELINOR Yeah, how did you find me so fast, Ari? Ari shrugs. ARI I just kind of... heard you were over here? ELINOR But I was totally quiet! I never said Polo. ARI Hmm, you're right. I'm not sure. Let's try again? He puts the blindfold back on and the girls find their places. They start playing again, calling and responding <SFX: WALLA MARCO! POLO!>. Ari heads right for Olive, who dodges out of the way and goes around a bush. Ari looks momentarily confused, then takes a few steps until Olive is in his line of sight, then easily goes to her and tags her. ARI (CONT'D) Got you! OLIVE But... how? How did you know I went around the bush? ELINOR Is the blindfold working? They check and it looks good. ARI I couldn't see anything! ELINOR Wow. I wonder how you were able to find us so well. OLIVE Yeah, even when we were super quiet? ELINOR Hmmm , we need more observations. Ari, do you have an extra eye somewhere? They check his head and forehead for a third eyeball, but don't find one. OLIVE Nope. So how did you do it? ARI (shrugging) I dunno . I can just... hear where things are? Just then, Mr. Bat comes over. MR. BAT Good news kids! The tent is all set up, so it's time to go for a walk! The kids <SFX: YAY! AWESOME!> and follow Mr. Bat, except for Elinor, who hangs back a little, still a bit puzzled. EXT CLIFFS -- LATE AFTERNOON A cross-fade later, Mr. and Mrs. Bat lead the kids on a walk with Miri in a baby carrier strapped to Mrs. Bat. Mrs. Bat takes out some baggies of trail mix from Mr. Bat's backpack. MRS. BAT Here, pass these out to your friends, Ari. OLIVE Looks good. What is it? Ari passes them around. ARI It's called "trail mix." It's got chocolate chips and other stuff. Elinor What other stuff? ARI I dunno . I only eat the chocolate chips. The kids <SFX: GIGGLE> as they munch on the trail mix. ELINOR I love going for a walk in a new place. MR. BAT Well, I'm excited to show you all something REALLY extra cool. They come around a bend and up to a lookout spot (with wooden guard rails) at the edge of a modest canyon. It's a nice view, and they can see pretty far down the canyon as the sun is low on the horizon. Across the canyon and to the right is a tall flat cliff face. OLIVE Wow, what a nice spot. It's SO beautiful here. MR. BAT Look at those smooth, tall rocks. ELINOR Wow, I've never seen rocks like that before. Ari goes to pop a chocolate chip in his mouth, but misses. He scrambles <SFX: WH-WHOA> , but the chip falls on the floor. ARI Oh NOOOO ! He goes to pick it up when, a moment later, his echo returns <SFX: (ECHO) OH NOOOOO...> . The kids are all really surprised. ARI (CONT'D) (finishing picking up the chip) Who said that? Mr. Bat smiles. MR. BAT Listen to this, and you'll figure it out for yourself. He cups his hands towards the cliff. MR. BAT (CONT'D) HELLO! A moment later his <SFX: (ECHO) HELLO...> returns. Olive and Elinor are amazed, and try it themselves by shouting out to the canyon. ELINOR HELLO I'm Elinor! A moment later, her <SFX: (ECHO) HELLO I'M ELINOR...> comes back from the cliffs to the right. The kids <SFX: LAUGH>. Olive <SFX: TRUMPETS> towards the cliff and it <SFX: (ECHO) TRUMPETS> back to her! ELINOR (CONT'D) How is that happening? ARI It's like the rocks are talking back to us. MR. BAT Haha , in a way, Ari. What you're hearing is the sound of your voice bouncing off those rock over there and coming back to us. That sound is called an 'echo'. We see a THOUGHT BUBBLE with a top view that illustrates sound as wiggly waves being emitted from the kids in all directions. One of the wiggly lines bounces off the cliff to the right and comes back. The visualizations are supported by sound mix effects when the waves are emitted. OLIVE Echo. I like that word. ARI That's so neat! ( to the canyon) ARI IS SO COOL! The cliff echoes back <SFX: ECHO ARI IS SO COOL>. ARI (CONT'D) Hey, the rocks agree with me. The kids <SFX: GIGGLE>. Elinor tries again. This time, she closes her eye in her effort to make it louder. ELINOR EXPLORING IS FUN! The cliffs echo back <SFX: (ECHO) EXPLORING IS FUN...> from her right. Elinor turns her head and opens her eyes. ELINOR (CONT'D) Hmmm . That is SO interesting. ARI What is it Elinor? ELINOR I shouted with my eyes closed, and from the echo I could tell where the rocks are. OLIVE That makes sense. When the shout comes back, it comes from the rock. So you can hear where it is, even if you have your eyes closed. ELINOR (excited) The echo lets you hear where the rocks are. In a repeat THOUGHT BUBBLE, we see another top view in which Elinor shouts, sending wiggly lines in all directions. The ones on the right bounce off the cliff and come back. OLIVE Ooohh . If we were playing Marco-Polo with the rocks, that would help. (closing her eyes) MARCO! (then) POLO! The cliffs <SFX: (ECHO) MARCO!... POLO!>. OLIVE (CONT'D) (pointing with her trunk) The rocks are that way! Elinor makes a connection. ELINOR Wait, is THAT how Ari found us when we played Marco Polo and we didn't make any sounds? Were you using echoes, Ari? ARI Was I? OLIVE I didn't hear him making any echoes. He found us without even saying "Marco". ARI I just... heard where you were. Maybe I have a special bat-sense? Mr. and Mrs. Bat look at each other knowingly. MR. BAT Actually, Ari, you do. You have a special bat echo. ARI Really? I do? I mean, of course I do. Uh, how does it work? MR. BAT Bats can make a special noise that bounces off of things to make echoes. ARI A special noise? Like this? <nonsense sound> MR. BAT Haha . That's a funny noise. I mean a special noise that most animals can't hear. ELINOR Wow, really? MR. BAT Yes! Only bats can hear it (he wiggles his ears), and we use it to tell what is around us. By listening to the echoes, we can tell where things are. We see a THOUGHT BUBBLE that shows Mr. Bat walking in the forest, emitting sound wiggles that bounce off trees and rocks (similar to the echo visualization earlier). His ears twitch as he registers the wiggles coming back from objects. The kids are <SFX: AMAZED WALLA>. ELINOR Why can bats do that? MR. BAT Well, lots of bats like to fly at night. Can you guess why this special echo would be helpful? The kids think for a bit <SFX: HMMM> . OLIVE I know! Because it's night and you can't see in the dark! It's like closing your eyes or wearing a blindfold. MR. BAT That's right. This special echo helps bats find things in the dark, like food. ARI Ooh , night snacks! They <SFX: LAUGH> and then kids sing to recap. ELINOR/OLIVE/ARI We say Echo! Echo! The rock says "Echo!" "Echo!" ( softer ) We say Hello! Hello! The rocks say "Hello!" "Hello!" ( softer ) ELINOR: I can use my eyes to see what is right in front of me. OLIVE: But bats can make a special sound To help them know What's all around. ALL: Bats use echos And special ears So they can tell What's far and near We say Echo! Echo! The rock says "Echo"! "Echo!" ( softer ) We say Hello! Hello! The rocks say "Hello!" "Hello!" ( softer ) During the sections about bats, we illustrate how echolocation is useful in the dark. As the kids finish the song, we see and hear Ari's stomach <SFX: GRUMBLE>. MR. BAT You don't have to echo that Ari, I know what that means: it's time for dinner! Over <SFX: LAUGHTER/AWESOME> merriment, they head back to camp. EXT CAMPSITE -- EVENING It's later, and everyone is sitting around a nice campfire, roasting veggie dogs on their long sticks. OLIVE I think mine is ready. ARI Hmm, mine needs another minute. I like it extra cooked. MR. BAT You mean extra burnt? ARI No, I like it burnt just right. They <SFX: LAUGH>. Ari takes his food off the fire and Mrs Bat puts it on plates to cool. MRS. BAT It's so nice to have a cozy campfire dinner. OLIVE That reminds me! I want to read my book by the cozy campfire. But... I left my book in my tent. She looks over into the darkness. OLIVE (CONT'D) And.. It's pretty dark over there. ARI I'll get it for you. Bats are great at getting around in the dark. He navigates confidently to Olive's tent, humming the tune from the ditty. Elinor looks at him and we see in a THOUGHT BUBBLE what she's thinking: she imagines Ari walking and the sound waves bouncing off the things around him. Ari then comes back, with an extra bag of trail mix in hand. ARI (CONT'D) Here you go, Olive. He gives Olive her book. MR. BAT And what else did you find? ARI An extra bag of trail mix. Like you said dad, bats are good at finding food in the dark! MR. BAT I'll echo that! Bats are good at finding food in the dark! They all <SFX: LAUGH> as the view pulls up into the starry night sky and we... FADE OUT. Segment 2. 1. Ext. forest -- summer Day Elinor and Olive are on a walk through the forest with Mz . Mole. As they pass a rocky slope, five small birds suddenly fly past and into a cave where they disappear into the darkness. The kids are amazed. ELINOR Whoa! Why did those birds go into that cave? Mz . Mole They’re flying home. They live in that cave. Perspective from inside the cave looking out at Elinor, Olive and Mz . Mole as they peer in. oliVE But it’s so dark in there. How do they know where to fly? ARI Helloooo ! Ari’s voice <SFX: ECHOES HELLO> around the cave. MZ . MOLE Some animals are really good at getting around in the dark. Instead of using their eyes, they use their ears. ELINOR How do they do that? MZ . MOLE I'll show you! Mz . Mole takes out her storybook and opens the front cover. CLOSE ON the storybook which shows a small bird called a swiftlet flying through the air. 2. THE STORYBOOK The storybook comes to life in a pop-up book style of animation and the swiftlet flies through the air <SFX: CHIRPING>. MZ . MOLE (v.O.) This little bird is a swiftlet . It is a very special bird that builds its nest inside a dark cave. Looking into the mouth of a dark cave, the swiftlet flies in. Then from a profile point of view, the swiftlet flies through the cave tunnels deeper into the dark. The scene suddenly becomes monochromatic or dark blue to indicate the darkness of the cave. The bird flies along and appears to be on a collision course with a low hanging part of the cave ceiling. Olive (V.O.) Watch out, little bird! The swiftlet suddenly swoops down and flies under the low hanging rocky projections from the ceiling and then up onto a nest stuck to the side of the cave wall. Close on the bird sitting on the nest. Elinor (V.O.) How does the swiftlet know where to go? MZ. MOLE (V.O.) Because it’s dark, a swiftlet can’t use its eyes to see. It uses its ears to find its way. ARI Can it SEE with its EARS? The swiftlet flies out of the nest and around the cave. As it flies, it <SFX: CHIRPS REPEATEDLY> and navigates around the rocky walls and ceilings, twists and turns of the cave. MZ. MOLE (V.O.) Ha! Not quite. As it flies, it makes chirps and then hears the chirps bouncing off the walls of the cave. ARI That's called an echo. MZ . MOLE That’s right. The echo bouncing back tells the swiftlet where the walls are, and that's how it gets around. Simple animation illustrates the sound of the bird’s chirps bouncing back to the bird as it flies. The swiftlet makes its way back to its nest where it perches once again. Elinor Wow, it HEARS where to go! A pair of little baby swiftlets pop their heads up with their beaks open. oliVE (v.O.) Look! It has babies! MZ . MOLE (V.O.) And soon these baby swiftlets will learn how to use their ears to fly safely in the dark cave. 3. EXT. FOREST -- SUMMEr Day The birds fly back out of the cave past Mz . Mole, Elinor and Olive. eliNOR and olive ( together ) Swiftlets are cool! The kids’ voices <SFX: ECHOES Swiftlets are cool... Swiftlets are cool...> around the cave. End

ELINOR WONDERS WHY EWW130A: ECHO LOCATION Written by Jorge Cham and Daniel Whiteson Question: How does Ari know where things are when he’s blindfolded? Logline: The kids learn about echo-location Curriculum Goals: LS2 . Understand that animals have different body parts that are used in different ways to meet their needs. a. Identify body parts of animals and their function c. Compare how the external body parts of animals and plants are the same and/or different d. Explore how different external features of an animal help it survive in its environment. (Elinor and Olive learn that Ari’s ability to make high-pitched sounds and his sensitive ears give him a special skill – echolocation). SEP1 . Asking questions (science) and defining problems (engineering) a. Demonstrate curiosity about the greater world outside of their local environment b. Ask more complex questions about observable phenomena c. Ask and/or identify cause and effect questions that can be answered by an investigation (Ari, Elinor and Olive wonder about how their voices are bouncing back near a cliff face. so they do an investigation that leads them to the idea of echoes). SEP3 . Planning and carrying out investigations b. Compare and contrast objects and events by describing similarities and differences in detail c. Demonstrate an ability to make and test predictions based on background knowledge and experiences. (Elinor and her friend contrast the echoes they all can hear with Ari’s echolocation abilities). SEP6 . Constructing explanations (science) and Designing Solutions (engineering) a. Use background knowledge experiences, and data to construct reasonable explanations and theories of natural phenomena (science) b. Look for and describe patterns and relationships in natural phenomena (science) (Elinor, Ari and Olive use their knowledge they’ve gained experimenting with echoes to understand Ari’s echolocation) FIRST DRAFT: January 13, 2020 SECOND DRAFT: January 29, 2020 POLISH DRAFT: February 26, 2020 RECORD DRAFT: March 02, 2020 ELINOR OLIVE ARI MR.
