Aquarium Calculus Grade Level: Duration: Grade 11/12 6x50 min Subject: Calculus Prepared By: Mike Borowczak Materials Needed Req: Graphing Paper, Rulers. Optional: Foam Board, Graphing Calculators Analyze Learners Overview & Purpose (STEMcinnati theme) Students will enhance & apply knowledge of both integration and differentiation in calculus. Students will discover how engineers must use calculus in creating large-scale attractions (e.g. walk-through aquariums). Education Standards Addressed AP Calculus Key Concepts II. Derivatives E. Applications of Derivatives Applications: Large Scale Attractions, Design of Vehicles/Suits Under Unique Stresses (Aircrafts, Space Vehicles, Deep Sea Explorers etc). Careers: Civil Engineers (and Environmental Engineers), Material Engineers, Architects, Mechanical Engineers, Aerospace Society: Entertainment, Exploration Analysis of curves, including the notions of monotonicity and concavity. Optimization, both absolute (global) and relative (local) extrema. Modeling rates of change, including related rates problems. III. Integrals A. Interpretations and Properties of Definite Integrals Definite integral as a limit of Riemann sums. Definite integral of the rate of change of a quantity over an interval interpreted as the change of the quantity over the interval: Basic properties of definite integrals. (Examples include additivity and linearity.) B. Applications of Integrals Appropriate integrals are used in a variety of applications to model physical, biological, or economic situations. Although only a sampling of applications can be included in any specific course, students should be able to adapt their knowledge and techniques to solve other similar application problems. Whatever applications are chosen, the emphasis is on using the integral of a rate of change to give accumulated change or using the method of setting up an approximating Riemann sum and representing its limit as a definite integral. To provide a common foundation, specific applications should include finding the area of a region, the volume of a solid with known cross sections, the average value of a function, and the distance traveled by a particle along a line. Goals & Objectives Teacher Guide Student Guide Assessment Goals and Objectives (Specify skills/information that will be learned.) Goals: Students will understand: 1.How to construct a solid by revolving functions around x & y axis 2.How to find the volumes of the solids listed in #1 as well as volumes constructed by the intersection of functions 3.How to rates of change are used in everyday settings 4.Students will see how calculus is used by engineers in the development of large scale attraction & theme parks Objectives: 1.Students will design a multi-room aquarium using their knowledge of integration 2.Students will compute 3 volumes for each room they design – 2 Areas below the curve, and the Area between 3.Students will draw and construct crosssections of each room 4.Students will compute & explain the rate of change of customers within their aquarium during the day 1. List at least five (5) ways that calculus applications exist in theme park / large scale attractions (such as Kings Island, Sea World, The Newport Aquarium, Cedar Point): 2. Write an equation for balance(t), the ratio between the rate of visitors entering an attraction and the rate of visitors leaving an attraction. Assume you are given enter(t), exit(t), functions describing the total number of visitors which have entered and exited from the attraction. 3. Using your answer for number 2, find the rate of change of balance(t). 4. Using your answers for 2 & 3; assume that enter(t) = 2t2+50 and exit(t) = 25 –(t-5)2 find balance(t) and the rate of change of balance(t): Balance(t) = Balance’(t) = 5. Given a building with width and length of 94 ft, and height 30 ft, a) Find the Volume of the building. b) Assume that we fill the Select Instructional Strategies – Information (Catch, give and/or demonstrate necessary information, misconceptions, etc…) Utilize Technology Day 1 Pre-assessment (10 minutes) Questions to the right Catch (n = 10 min) Discussion of Local Theme Parks Leading Questions: how do they design: o coaster loops so that people don’t fall o tunnels so that a Million Gallons of water don’t implode on visitors o how large a concession area is needed in the middle of an attraction Lesson (continuous during activity) o Reinforce integration of volumes and solids around axis o Reinforcement of Rates-ofChange Discussion (n = 5 min) Discuss Key Observations Homework (Student Determined) Students may work on their projects outside of school hours (e.g. added features, visual appeal) Wolfram Alpha can be used for free visualization Catch Students should notice that calculus is required to perform computations that would otherwise would be determined by trial and error. Other Resources (e.g. Web, books, etc.) Require Learner Participation Activity (Describe the independent activity to reinforce this lesson) Day 2-5 Overview (n = 5 minutes) Handout Aquarium Calculus Instructions Students Paired Review Expectations & Deliverables Activity (4 days) Overview The XYZ Economic Development Council has determined, using market analysis and surveys, that in order to bring in local revenue and long-term jobs to the area – the creation of a large-scale attraction style aquarium is a viable investment project. Request The council is soliciting initial proposal bids from a minimum of 5 Engineering & Design firms. The top 3 bids will be partially funded for further analysis & forwarded to the architectural bidding phase. Constraints 1][An area of land has already been set aside for the project, and due to zoning regulations, the maximum size of the building is set at 94 ft wide, 94 ft long and 30 ft tall. 2][In order to be competitive with other comparable local attractions (The Newport Aquarium) your bid must include an aquarium with contains at least 1 Million Gallons of water (preferable more). Write the function the shows the amount of water in your aquarium water = total volume of building – volume of aquarium rooms 3][You must design a minimum of 4 separate rooms. The rooms must have the following characteristics: The rooms must be formed by rotating a 2-D shape around a line At least 3 of the rooms must be created by the intersection of two lines 4][You must draw out the three views of you aquarium layout to scale Sagittal View (Y-Plane) Coronal View (X-Plane) Transversal View (Z-Plane) 5][Each member must each also create the cross-sections for at Evaluate (Assessment) Day 5 Standard Post-Assessment Additional Notes (Steps to check for student understanding) – See Objectives above Important Attachments: 1. Pre-Post Assessment 2. Worksheets 3. PowerPoint 4. Reflection after lesson Reflection: What worked: Student’s enjoyed a hands on application to calculus – e.g. sketching an aquarium, defining equations to form the walls, transferring the forms to foam and cutting it out. Concept to Implementations they could see how calculus gets used to engineers & designers. Students also enjoyed the re-enforcement of seeing a large scale attraction and being able to compute the volume & surface areas of not only the aquarium walls, but the visitor occupation volume. What needs more polishing: Student groups were split on designing their tanks – some groups wanted more direction – they didn’t understand that it was freeform- they were too worried about the calculus than enjoying the fact that they were free to create anything. In order to combat this a prize mechanism – e.g. group able to have the closest balance between water volume and guest volume get prize XYZ, the group with the most complex shape get ABC, and so forth. Additionally, as expected, this activity brought out fundamental misunderstands on the students part for computation of volumes by revolving areas. As such, our timing slipped and we ended up taking 7 classes + 1 day for a field trip.
