Bullseye Models Using Excel And Geometer's Sketchpad, Heather Hoad

#### Bullseye Models Using Excel And Geometer's Sketchpad, Heather Hoad

*Lesson Plans*

Throughout this problem students explored the concepts of probability, percentage, and graphic representations of data. Students began by discussing the variables involved in playing a game of darts including: player skill level, strength, accuracy, coordination, gravity, etc. They then made hypothesized the number of darts out of 100 attempts that would land in each of the point value areas. During the remainder of the project, the class tested their hypothesis through a real life dart board model and an online dartboard simulation model. Students used a real-life magnetic dartboard to collectively gather data on 100 darts thrown and an online ...

Modeling Traffic Patterns Using Java, Kim Meek

#### Modeling Traffic Patterns Using Java, Kim Meek

*Lesson Plans*

The students plan to create a program that models the traffic during the day at Twelve Corners. Like the Marine Biology Simulation, the cars will be able to move forward and make turns according to the traffic patterns. They will use the MBS as a guide to develop their own program, which will enable an analysis of various traffic patterns. If it turns out that this is too lofty a goal, the students will be able to make modifications to the MBS to enhance its capabilities. Either way the students will learn the MBS by applying it to a real-world ...

Freshman Class Analysis Using Agentsheets, Kristen Frank, Brian Bizzigotti

#### Freshman Class Analysis Using Agentsheets, Kristen Frank, Brian Bizzigotti

*Lesson Plans*

The 2005 CMST Challenge Project is to survey the ninth grade class at East High School to see how many of their lives are affected by: pregnancy, drug use, crime arrests, family structure, student employment, and value of education. It was very hard to find the percentages of these factors for the United States. Therefore only certain questions will be used in the simulation. The results of the survey will be run through an agent sheet simulation to estimate the number of students that will successfully graduate using the data collected from the 2004/2005 freshman class.

In order to ...

Potential And Kinetic Energy - What's It All About?, Fayne Winter, Larry Bedgood, Susan Cooper

#### Potential And Kinetic Energy - What's It All About?, Fayne Winter, Larry Bedgood, Susan Cooper

*Lesson Plans*

Our investigation deals with the difference between kinetic and potential energy, and different situations that model those energies. Students needed to define kinetic and potential energy. In addition they needed to discover what the equations are to calculate these energies. Students were to investigate different situations where these energies are evident using various modeling technologies and design a tangible model they could use to assist in explaining the difference between the two energies. Once students designed these models, they needed to be able to explain where these energies exist in these situations using verbal explanations, mathematical equations, physical displays, and ...

Newton`S Law Of Cooling, Carneathea Melson

#### Newton`S Law Of Cooling, Carneathea Melson

Radioactive Decay Using Stella And Agentsheets, Annette Pennella, Dorothy Java

#### Radioactive Decay Using Stella And Agentsheets, Annette Pennella, Dorothy Java

*Lesson Plans*

The topic of our Challenge Project is the half-life of radioactive elements. We chose this topic for several reasons. The 8th grade curriculum includes the investigation of fossils and radioactive elements. Students often have difficulty understanding and relating to this natural event since it cannot be observed. They do not see how it affects their lives today. Mrs. Java and I decided to have at least two of the investigated elements be related to medical procedures. The students are able to relate what they have learned and see how this information has an impact on peoples’ everyday lives. The radioactive ...

Students will discover that math calculations such as surface volume, volume and shrinking and stretching concepts have a lot to do with how biological systems function. Students will participate in a lab that models the diffusion of molecules through cubes of different shapes. They will take measurements to see how far a substance diffuses into different sizes of cubes (ie cell). Students will then use Geometer's Sketch pad to manipulate sizes of different objects and be able to relate how size changes surface area & volume (shrinking & stretching).
