Tour de France with Stella and TI CalculatorThe main purpose of this challenge project was to incorporate the modeling technology that we used in the CMST program at the summer academy. This also served to teach us the modeling software in a solid, more meaningful way. The main purpose of this challenge project was to teach the students to gather, organize, and display data. Throughout this project we also had the opportunity to use technology in order to solve realworld problems. This allowed the students to relate the information to their own personal lives and activate their prior knowledge. The modeling software and technology was a wonderful medium to engage and motivate the students. Using various forms of software and models, our students were able to concretely visualize the effects that data has on tables and graphs. The software allowed the students to instantly see changes and follow specific pieces of information over periods of time. It became very simple and fun for the students to compare and contrast the various forms of data. Not only did we have the opportunity to develop a deeper appreciation for technology, but we also had the chance to pass this knowledge on to our students. We taught the students how to use models and technology such as Stella, the TI83 graphing calculator, Excel, PowerPoint, the Internet, a digital camera, and the Promethean Board. In order to incorporate and utilize the many forms of technology and modeling software, we created the ‘Tour De Technology’. As part of this project, the students were asked to research the Tour De France and properly organize and label their data. The students were then instructed to represent their data using graphs and in Stella. As a result of the tables and graphs, the students were able to visualize the effects that terrain, speed, and distance has on the rider’s finish time.

Mathematics of Bungee JumpingUpon completion of this lesson, students will: create their own model of bungee jumping analyze graphs comparing acceleration, distance, and speed versus time

African Population Modelling Using StellaAt the end of this lesson, the student will be able to identify factors that hinder or enhance population growth. The student will be able hypothesize a plan that will provide population control for Africa. The student will then test their hypothesis on the model.

How to Manage your MoneyThis lesson will teach students how to manage the money earned from a summer business. Students will have a lemonade stand, offering lemonade, ice tea, cookies, and twinkies. They will use Microsoft Excel to calculate the amount they need to start up the business, and to keep track of their expenses and revenue each week. They only need Microsoft Excel to do this lesson. They will also have to create their own spreadsheet according to their needs and vision.

Gravity Influence on Flight PathsThis activity models the height of a projectile with the TI83+ graphing calculator. The topics covered are gravity, acceleration due to gravity, rate of change, and height in a real world situation that students might one day have to solve. This presentation would fit into the physics or math curriculum best, but it could be used to teach students how to interpret graphs from the calculator in a different course that isn’t worried about the equations behind it.

NY State Standard :Key Idea 7 Patterns/functionsBy the end of this lesson, all students will be able to calculate the amount of monthly payments at a given interest rate for a specific loan using Excel. They will also calculate the total cost of the loan.

Ecological EquilibriumUpon completion of this lesson, students will: · Have been introduced to computer modeling. Have a better understanding of setting up and utilizing the functions of Microsoft Excel. Have a better understanding of the complexities of the ecological equilibrium time and evolution have created

Marble Motion LabIn this lab you will be recording the distance a marble travels over a period of time with a TI83 CBR and TI83 Plus Silver. Upon completion of this lab and analysis of the data, you will be able to determine the average speed of the marble over a given time interval and the average distance the marble traveled during the time period.

Graphing Quadratics Using TI CalculatorUpon Completion of this lesson the student will be able to: Recognize a, b, and c in quadratic equations Understand the role of a Understand the role of –a

Plant Growth RateThe lesson is intended to address the different in growth rates exhibited by plants by the amount of water they receive and the amount of sunshine they receive. The lesson will incorporate observation, writing, use of technology, group work and individual work. Standard 4.

Population Dynamics Using Stella for ModelingTo…Introduce students to Stella modeling software by having students develop a simple population model and have students experiment with parameters on a more complicated food chain model.Students will be able to…? Build a basic Stella model of a population incorporating birth and mortality rates.? Use a prebuilt Stella model to represent relationships, make conjectures, and model the dynamics of a food chain.

Graphing Linear Equations Using TICalculatorStudents will be able to represent and analyze using verbal descriptions, tables, equations, and graphs working in groups of two within a given block period.

Toothpickase Activity1. Enzyme activity 2. Enzyme reaction rates/slopes 3. Use of the TI83 4. Use of Excel 5. Regents Living Environment Standard 1 and 4

How Does a Little Add Up to a Lot?Students find the amount of water wasted due to a leaky faucet as a result of designing and carrying out their own experiments that model this common, realworld situation. Graphing their data, students are then able to write an equation for the line of best fit. This equation, in turn, allows them to make predictions concerning the amount of water wasted over a long period of time or the amount wasted by multiple leaks.

Unit on Volume and Surface AreaTo solidify computation of volume and surface area of rectangular prisms and cylinders using a technology tool, and comparing volumes and surface areas between objects. Students will be able to… • setup an Excel spreadsheet for the calculation of volume and surface area of any two rectangular prisms and any two cylinders, • check their setup to assure accuracy of their model, • compare volume between rectangular prisms of different dimensions, • compare surface area between rectangular prisms of similar volume, • generalize minimizing surface area of a rectangular prism, • compare volume between cylinders of different dimensions, • compare surface area between cylinders of similar volume, • compare volume between rectangular prisms and cylinders of similar dimensions

What is Temperature?Upon completion of this lesson student will:  Choose a scale and graph data in tables.  Identify the independent and dependent variables.

Oh, Deer (population dynamics using Excel)The learner will be able to identify the carrying capacity, and population trends of an animal population. The learner will be able to understand the interaction of one population is dependent upon another in an ecosystem and see how non living factors play a vital role in that ecosystem. The learner will demonstrate their proficiency in their understanding in these things by participating in and completing the “Oh Deer” lab.

Population Simulation with M&MsThis activity involves two simulations with M&M`s® to explore population growth and decay. The followup activity, Population Simulations with Calculators introduces NOWNEXT or recursive equations as an accessible way to model this behavior and expand to other population models.

Ice Cream Graphing LabGuided data collection through graphing with provided example. Student survey will be conducted in the classroom, focusing on the (3) favorite flavors of ice cream, frequency of eating ice cream, soft versus hard and preference for brand of ice cream.

Does Exercise Affect a Person’s Heart?1. Students will count off 17 forming 7 groups of 4. 2. Assign each group an exercise: situps, jump rope, running in place, hand weights, walking and jumping jacks. One group will be a control at rest. 3. Each student in the group will perform the exercise for a total of 20 minutes, taking a pulse rate every 2 minutes and record. 4. Students are to enter the data onto an EXEL Spreadsheet. A summation of the “20 minute” data for the 4 students is then averaged. 5. A class data is added to spreadsheet by having the students post their averages on the board. 6. A bar graph is constructed and used to help in answering the Exploration Questions.
