WEBVTT 00:00:00.000 --> 00:00:06.914 The hare brings his finish sign onto the little stage and notices another pair of ears on the 00:00:06.914 --> 00:00:07.435 ground. 00:00:07.435 --> 00:00:10.409 He steps forward, and the shape follows. 00:00:10.409 --> 00:00:11.822 “Who is copying me? 00:00:11.822 --> 00:00:12.565 ” he asks. 00:00:12.565 --> 00:00:15.242 Look for the light before answering. 00:00:15.242 --> 00:00:21.264 The hare blocks some light, and a darker region appears on the ground behind him. 00:00:21.264 --> 00:00:25.799 The shadow is not a second character living inside the floor. 00:00:25.799 --> 00:00:32.416 We can still imagine it as a companion in a story, while keeping our explanation of light 00:00:32.416 --> 00:00:34.721 separate from that imagination. 00:00:34.721 --> 00:00:40.000 Find the light marker, the hare and the surface where the shadow falls. 00:00:40.000 --> 00:00:45.315 Place the light to one side of the hare and notice where the dark ears fall. 00:00:45.315 --> 00:00:50.350 Move the direction control to the opposite side, keeping the hare still. 00:00:50.350 --> 00:00:55.245 The shadow changes position too, falling away from the incoming light. 00:00:55.245 --> 00:00:59.161 Watch the marker, the character and the ground together. 00:00:59.161 --> 00:01:02.028 Our simplified stage uses parallel light. 00:01:02.028 --> 00:01:08.671 A household flashlight close to a toy also changes the shadow with its distance, so its results 00:01:08.671 --> 00:01:11.189 need not match this diagram exactly. 00:01:11.189 --> 00:01:16.643 Turn the direction slowly and try to point the shadow towards the finish sign. 00:01:16.643 --> 00:01:20.000 Predict its direction before moving the control. 00:01:20.000 --> 00:01:24.791 Keep the light coming from the same direction and raise it higher. 00:01:24.791 --> 00:01:29.728 The shadow becomes shorter, drawing the ears nearer the hare’s feet. 00:01:29.728 --> 00:01:33.575 Lower the light and the shape stretches farther away. 00:01:33.575 --> 00:01:40.109 The toy’s size and position stay fixed; the height angle of the light is the condition you 00:01:40.109 --> 00:01:40.617 change. 00:01:40.617 --> 00:01:45.699 This is a simple illustration, not a precise measurement of your room. 00:01:45.699 --> 00:01:51.869 Make a prediction, move the slider, then compare the shape against the base markings. 00:01:51.869 --> 00:01:56.878 Reverse the change and check that you can recover the earlier shadow. 00:01:56.878 --> 00:02:00.000 Which position makes the ears look longest? 00:02:00.000 --> 00:02:06.196 The hare tries to put the shadow in his pocket, but turning around changes where it falls. 00:02:06.196 --> 00:02:09.294 “You cannot come along on your own,” he says. 00:02:09.294 --> 00:02:15.146 Arrange the light direction and height, then compare the result with your prediction. 00:02:15.146 --> 00:02:19.484 A real opaque prop placed in a light path can also block light. 00:02:19.484 --> 00:02:25.473 This virtual stage illustrates the main character’s shadow; it does not calculate every 00:02:25.473 --> 00:02:28.571 possible household lamp and prop arrangement. 00:02:28.571 --> 00:02:34.836 Explain which part of the scene is the hare’s imaginative story and which part describes an 00:02:34.836 --> 00:02:36.489 observation about light. 00:02:36.489 --> 00:02:40.000 Both can belong in your telling, with clear labels. 00:02:40.000 --> 00:02:42.968 Ask an adult for an ordinary flashlight. 00:02:42.968 --> 00:02:49.351 Keep the toy and marked base steady on a table, and compare light from two directions. 00:02:49.351 --> 00:02:53.803 Keep the beam away from eyes and do not use a laser pointer. 00:02:53.803 --> 00:02:59.072 The printed light marker only marks a position; it does not emit light. 00:02:59.072 --> 00:03:03.302 The opaque prop lets you continue exploring at the table. 00:03:03.302 --> 00:03:09.610 Take turns being lighting designer and narrator, giving the shadow an imaginary walk. 00:03:09.610 --> 00:03:15.473 The shadow cannot be packed away, but you can keep the hare and your questions. 00:03:15.473 --> 00:03:20.000 Next time, invite the tortoise and compare a different shape.
