Engineering in Elementary Science: Designing with FOSS

Transcription

1 Engineering in Elementary Science: Designing with FOSS FOSS Presenters: Erica Beck Spencer, Diana Velez, and Brian Campbell FOSS Program The Regents of the University of California Can be used with permission.

2 Goals Explore the ways FOSS provides students with regular engineering experiences within the context of a science program. Examine how engineering is presented throughout NGSS as both disciplinary core ideas as well as practices.

3 Agenda Today we will Engage in an investigation from a new third grade module called Motion and Matter Discuss how engineering is integrated into the NGSS Consider the multiple ways engineering is integrated into the FOSS program

4 Full Option Science System FOSS is a complete, modular, research-based curriculum developed at the Lawrence Hall of Science with support from the National Science Foundation.

5 Overview of FOSS Next Generation All FOSS 2012 Complete Kits Include: 1 Teacher Toolkit 32 FOSS Science Resources books 1 FOSS Science Resources big book (K-2) Equipment kit for 32 students; 2 class uses Measurement tools included in kits!

7 Appendix I Engineering Design The Next Generation Science Standards (NGSS) represent a commitment to integrate engineering design into the structure of science education by raising engineering design to the same level as scientific inquiry when teaching science disciplines at all levels, from kindergarten to grade 12. There are both practical and inspirational reasons for including engineering design as an essential element of science education. From NGSS Appendix I

8 Grades 3-5: Engineering Design Process From NGSS Appendix I

9 Spectrum of FOSS Engineering Activities FOSS has 1 Whole investigations or instructional sequences that are explicitly about engineering and design. (MM) 2 Activities that are explicitly engineering experiences. (EE solar cells) 3 Engineering related experiences such as making models to demonstrate or explain scientific principles. (LS heart model) 4 Several (and we are developing more) extensions that are engineering related projects. (MIOW boxes) 5 Readings or multimedia about engineering (BM roller coaster)

10 Motion and Matter Investigation 1 Forces Magnets Investigation 2 Patterns of Motion Students explore the motion of wheel and axle systems, cups, twirly birds, and tops Investigation 3 Engineering Investigation 4 Mixtures Mixing solids, mixing solids and liquids, reactions, and Metric Field Day

11 Investigation 3--Engineering Part 1 From Here to There Part 2 Distance Challenge Part 3 Investigating Start Position Part 4 Cart Tricks

12 Part 1: From Here to There Design challenge: Make a cart that rolls from here to there with a small push or pull. Constraints (materials and time) Available materials Shafts, green (2) Disks (4 red and 4 yellow) Tongue depressors (2) Craft sticks (4) Binder clips (4) Straws (2) Index cards(3) Tape/scissors Time 10 minutes

13 Making Carts Design challenge: Make a cart that rolls from here to there with a small push or pull. Criteria: The success of a designed solution is determined by considering the desired features of a solution. In other words, engineers need to specify how they will determine if they have successfully met a design challenge.

14 Part 1: From Here to There Name the challenge Name the constraints Name the criteria that will determine if your design is a success

15 Name the challenge Make a cart that rolls from here to there with a small push or pull Name the constraints Name the criteria that will determine if your design is a success

16 Name the challenge Make a cart that rolls from here to there with a small push or pull Name the constraints Time and materials Name the criteria that will determine if your design is a success

17 Name the challenge Make a cart that rolls from here to there with a small push or pull Name the constraints Time and materials Name the criteria that will determine if your design is a success The cart must roll from here to there with a small push or pull.

18 Solve a Common Problem What do you have in your bag of materials that would help you to solve this problem? What will allow the wheels to rotate freely?

19 Solve a Common Problem Axle: a rod that supports wheels Bearing: A part in a machine that supports or guides a rotating part. A bearing reduces friction so the part can rotate freely. Bearings Axle

25 Hmmm Focus Question: What are some important features of a cart?

26 Focus Question: What are some important features of a cart? Please answer the FQ using drawings and words and make note of any problems and solutions

27 Part 2: Distance Challenge Use a ramp and measure how far the car travels from the base of the ramp Additional Available materials Meter tape (1) Ramps (1) Clothes pins (4) Record 3-5 measurements in notebooks

28 Part 2: Distance Challenge FQ: How can you improve the design of your cart? Design challenge: Make a cart that travels 15 cm farther than the longest run Constraints Available materials Meter tape (1) Ramps (1) Clothes pins (4) Time (of course!)

29 A bit about failure To experience failure does not mean you ve failed It is part of the process.

30 From NGSS 3-5-ETS1 Engineering Design 3-5-ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

33 Part 3: Investigating Start Position Today you are going to work with your team to determine how the starting position on the ramp affects how far the car travels. It will be up to you to design an investigation and then carry it out. Please write a focus question before you begin. But wait

34 Part 3: Investigating Start Position Available materials Same as for Part 1 and 2 and Sticky notes (three each of three different colors) Start Position sheet Data table

35

36 Part 3: Investigating Start Position Work with your team to determine how the starting position on the ramp affects how far the car travels. It will be up to you to design an investigation and then carry it out. Please write a focus question before you begin.
