Unit Plan Overview Unit Topic: __[SCIENCE] - Structures_(Approx. 11 Lessons)____ Name:_____Stephanie Kwok_____ PLOs Objectives (SWBAT) Introduction Development Grade Level: ___3______ Lesson # ___1___ -Describe shapes that are part of natural and humanbuilt structures (eg., domes, arches, pyramids, triangles, cylinders) -Understand what a structure is -Differentiate & recognize natural & man-made structures -Be able to identify different shapes seen in -Brainstorm examples of natural & man-made structures. (bee hives, beaver dams, spider webs VS. buildings, cars, storage units) -What forces do structures have to withstand? Describe static & dynamic forces (eg., weight vs. wind) Lesson # __2____ -Compare effects of different materials, shapes and forces on the strength and stability of different structures. Lesson # ___3___ -Compare effects of different materials, shapes and forces on the strength and stability of different structures. -Shape properties; relative strengths, and strengths/weaknesses -Different purposes of different material usage. *-Explore layering. -Understand properties of different shapes. -Understand how these shapes provide different types of strength, stability, and balance. *-Explore folding. -Review 2D vs. 3D shapes. -Review & list different shape types (2D: triangles and squares; 3D: domes, arches, pyramids, triangles, cylinders) -Stability & balance are also dependent on foundation *-Explore what happens with folding Activity: Imagine you are a pioneer. There is not enough room for you and your family to sleep in the wagon, so you have to build yourself a place to sleep for one night. How would you build your shelter? What materials would you use? Would you change anything if you had to sleep there for more than one night? Draw a picture and write an explanatory journal entry. Experiment: Compare the usage of different materials (tissue, paper, cardboard) to withstand forces of weight and wind. Create a hypothesis, and then test results. -Explore what happens with layering these materials. -Describe properties of some common materials and evaluate their suitability for use in building structures. -Discuss why similar structures may be made of different materials? (eg., running shoe vs. rain boot) -Discuss how some materials are better than others. -Story of 3 Little Pigs -Hypothesize: How will a bag’s strength change if you place another bag inside? -What about if a tissue is soaked in water? Activity: - Use a piece of paper to create different types of columns (rectangular, triangular, circular). Standing it up, place a second piece of paper on the top surface. Hypothesize how many [small object weight]s will the column hold. Test and record results. *Additional Activity: Have students try balancing on 1 leg, then balancing with 2, 3, and 4 points of their body touching the ground. Closure Assessment Formative: Summative: Tools: Materials -Discuss reasoning behind different materials and structure shapes. For what purpose(s) are the structures to be created? What forces/factors must the structures be able to withstand/take into account? -Science Journal/Booklet (will contain worksheets & assignments to be completed throughout unit) -Be able to list examples of natural & man-made structures. -Demonstrate reasoning behind creating a structure. -Discuss how layering materials makes structures stronger. Layering also serves other purposes also (eg., layers within quilts increases warmth) -Discuss which shapes the students found to be the strongest/sturdiest. Perform comparison test as a class between triangular prism and cube. -Science Journal/Booklet: -Be able to list materials in order of strength. -What are some properties of some of these materials? (eg., plastic is waterproof) - Science Journal/Booklet: -Compare 2 pictures of simple bridge structures, 1 made with triangles, 1 made with squares. Hypothesize which is stronger. -Science Journals -> drawing sheet, pencil crayons. -Tissue, paper, cardboard, weights (such as pennies/small blocks) -Toothpicks, gumdrops (or marshmallows). For students who finish early: -Puzzle sheets that draw upon knowledge of material properties. -Can color title page -Optional free design activity pages (to inspire creativity): eg., Can you design a home for a mermaid? A sailor?) -Students requiring extra assistance may work with a partner. Extensions/ For students who finish Modifications early: Additional Questions: -How will you adapt your pioneer shelter design if: a) It is raining out b) The ground is muddy and your shelter needs to be elevated. -Can also color title page --For ELL students: -vocabulary sheet with visual aids. -Graphic organizers for worksheets. Additional Resources Extra Notes -Concept of pioneers should have been introduced by this time as it will be a major integrated unit stemming from Social Studies, thus also carrying over into Science. -3 Little Pigs book for any students who have not read it Extension Activity: Build structures with toothpicks and gumdrops. Experiment. Unit Plan Overview Unit Topic: __[SCIENCE] - Structures_(Approx. 11 Lessons)____ Name:____Stephanie Kwok_____ PLOs Objectives (SWBAT) Introduction Development Grade Level: ____3______ Lesson # ___4___ -Compare effects of different materials, shapes and forces on the strength and stability of different structures. -Observe what they have been learning about in the environment around them. -Observe different geometrical shapes in the structures within their community -Compare and hypothesize about the different materials used for the structures they observe, and speculate about the different forces they may have been built to withstand/support -Take class out into the community to observe interesting structures. Lesson # __5____ -Compare effects of different materials, shapes and forces on the strength and stability of different structures. -Integrate what has been learned about shapes to build a bridge. -Explore joint construction. Lesson # ___6___ -Conduct investigations into ways to improve the strength and stability of structures -Bridges -Compare/read about two examples of bridges, one successful, and one unsuccessful. -Compare/read/discuss about examples of successful and unsuccessful structures. eg.) Leaning tower of Pisa -Students required to make a sketch on a structure of their choice, then make notes about it. Questions: a)What materials do you think this structure is made of? b) What do you think the purpose of this structure is? c) What shapes can you see in this structure? Activity: Design a bridge that can hold a minimum weight based on what has been learned. Activity: Given an assortment of materials, design and then build a “sturdy structure”. Design based on what has been learnt, then build structure to test results. Record findings and reflect. Be able to justify design choices. -Integrate what they have learned about materials and shapes to create a sturdy structure. Closure -Group students together who observed the same structures to discuss and share answers and thoughts. -Peer feedback/observations -Discuss pros/cons of the different models -Peer feedback/observations -Discuss pros/cons of the different models -Reinforce main concepts that help in building strong/sturdy structures.

Some Key Concepts: -Structure strength dependent on materials used. (eg., brick > wood) -Forces that must be considered when building a structure (eg., wind & weather conditions, weight) -Particular shapes are stronger than others (triangles, arches and domes over rectangular prisms)
