Lesson 5: Motion  1 Grades K 2 
Possible Questions What makes the parts of a Rickey sculpture move, and change direction? How are these sculptures similar to and/or different from windmills? Can you make a sculpture that moves in the wind? Teacher help: Beginning/introduction: Ask the children about how things move  discuss everyday items moving  e.g. the students walking, cars, leaves on the trees  some of these items should have regular movements (we say constant or fairly regular pushes/forces), and others should be variable like the wind or water in a stream, etc) Introduce them to Rickey sculptures  need a video of at least one of them moving Middle: children form groups to discuss questions and then write down answers (1, 2, or 3, or assign each group different questions); groups report back to the whole class; each group builds a model  suggest using string, cardboard and paper or other materials? Summing up the experience: assemble sculptures together  discuss these sculptures in terms of the 3 original questions; ask for volunteers to tell you their new ideas about the three original questions; you can challenge them to think about other things that move in the same or different ways. Extensions: The balance   how do kitchen balances work? Knifeedges; where does the wind come from... Some Standards Science K.3.2 Investigate that things move in different ways, such as fast, slow, etc. (Core Standard) 1.3.4 Investigate by observing, and then describe how things move in many different ways, such as straight, zigzag, roundandround, and backandforth. (Core Standard) 1.6 Students begin to understand how things are similar and how they are different. They look for what changes and what does not change and make comparisons. 2.3 Students investigate, describe, and discuss their natural surroundings. They wonder why things move and change. Mathematics K.48.4 Students identify common objects around them and describe their geometric features and position (geometry) {+ more standards  or perhaps put them all in a note at the end }
