A scientific approach to amusement park ridesstudents were asked to create roller coaster rides that demonstrate physics principles such as: gravity, Gforces, Newtons, acceleration, velocity and force. Newton’s laws were discussed in preparation for the rides. The students were divided into groups and asked to think about some main objectives for the ride. Examples included: Safety, acceleration, weightlessness (zero gravity), and drastic changes in force. They then created a “blueprint” of the ride with a ride name, length safety features and description of the ride.

Animating Slope and YInterceptIn 8th grade math, we investigate graphing lines from equations for the first time. Students learn about the xy coordinate plane, the table of values, the slope and the x and y intercepts. They begin to understand y = mx + b, the general equation for a line. As a teacher, I have encountered many problems while teaching this content without the benefits of technology. It’s my goal to teach the effects of changing the slope and the yintercept. With traditional methods, we create a table of values and draw a graph by hand, which consumes a lot of instructional time. By the time the graphs are made, if the students are careful, they can draw some conclusions about slope and yintercept. The first graphs that 8th grade students create usually are not usually accurate enough to learn the concepts from. It’s also a challenge to have students stay focused on discovering the effects of slope and yintercept when there are many potential mistakes in the table and graph alone. As my Challenge Project topic, I wanted to create a model that would show a more efficient, visual representation of the effects of slope and the yintercept on the graph of a line. To create models that illustrate this area of the curriculum, we used the TI graphing calculators and the Geometer’s Sketchpad software. The students began to graph lines using the calculator. It addressed the following the New York State Standards. Students will: 8.G.13 Determine the slope of a line from a graph and explain the meaning of slope as a constant rate of change, 8.G.14 Determine the yintercept of a line from a graph and explain the yintercept. 8.G.17 Graph a line from an equation in slopeintercept form (y = mx + b) As they understood the concepts, we worked with Project Interactivate and found that our conclusions were correct. The combination gives the students a variety of different technologies and models to get understanding from.

Architectural Design – Roofs and RampsObjectives: • To have students design and calculate ramps and roofs controlling slope, as a major constraint in the design process. • To impose a grid on a line to quantify the steepness of a line • To introduce slope as the ratio of the vertical change divided by the horizontal change. • To illustrate the slope characteristic of lines a positive, zero, negative, or undefined (no slope) • To associate the terms with the appropriate graph of a line: increasing, horizontal, decreasing, or vertical. • To observe that the slope of a straight line is constant • To apply these mathematical concepts in the solution of roof and ramp design following architectural and anthropometric limitations.

Area CircumferenceStudents will be able to identify and apply formulas for the circumference and area of a circle in the design of a vegetable garden for Science class

Bacteria Growth Lesson PlanIn this lesson’s activities, students will use scientific inquiry, computer modeling, and graphical analysis in order to extend concepts from a specific lesson example to broader general trends and themes in biology. The following criteria are from The Living Environment Core Curriculum, from the University of the State of New York and the New York State Education Department: STANDARD 1 Students will use mathematical analysis, scientific inquiry, and engineering design, as appropriate, to pose questions, seek answers, and develop solutions. STANDARD 4 Students will understand and apply scientific concepts, principles, and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science. Broad Objectives: Students will investigate the basic structure and function of bacterial DNA and how mutations affect bacterial populations. After the activities, students should be able to explain the ways mutations can be both harmful and beneficial. The expected product in this lesson objective is a computersimulated bacterial culture and a graph of the population growth curves. The condition for demonstrating success at this task is activity in studentpairs and small groups. The criterion for success is an example of adaptations in other organisms and an explanation of how the environment determines the efficacy and value of the adaptation. Students are expected to extend and apply the concepts of mutation and adaptation to all organisms in general. Learning Outcomes/Specific Objectives: Students will be able to draw the basic structure of DNA, use computer modeling to show how mutation can result in both adaptation and maladaptation, and graph the population growth curves of simulated bacterial populations. Students will submit a 1 page written summary of the lesson and activities, including the drawing of DNA and the growth curve graph, in order to demonstrate their proficiency. Set Induction and Content: Bacterial population growth. Activities: For these activities, each student will pair with another, review the text section on bacterial genetics, and apply their knowledge to this and later activities. First, students will discuss the textbook section and then answer the following questions. Each studentpair will then join another pair for the simulation activity. Literacy Strategy: This proposed lesson utilizes computer modeling and small group discussion. Closure, Evaluation, and Assignment: After having engaged in classroom activities, students will provide examples of adaptations in other organisms in their write up. In the class discussion, students will talk about why mutations are important in the fields and subfields of biology, especially medicine. The class will discuss how the principles and processes represented in the simulation are explored through laboratory activities, including realtime bacterial culture plate incubation. For the next lesson on bacterial genetics, students can use the textbook chapters and biology websites to investigate the topic of antibiotic resistance and how genetic recombination produces new bacterial strains. The primary file is a lesson plan, accompanied by supplemental files. In the supplemental zipped files, you will find: Student worksheets Lesson plan Powerpoint presentations

Ball And Ramp, How Far Can You Move It?Using Interactive Physics 4 eighth grade students explored the question “What are the best combination of variables to move a 2 kilogram mass 20 meters?” This was the first introduction for these students to this program. As part of the NYS 8th grade Performance Test students must run an experiment using a golf ball and ramp to move a cup. They have to run 3 trials by rolling the golf ball down a ramp from a 25 cm release point. They then record the distance the cup was moved. On the Performance Test they are instructed to use the distance recorded to show a general pattern of movement and explain why this pattern could be observed. They are then asked to extrapolate this data to other variables that may effect movement. This Interactive Physics exercise was used to help students prepare for this Performance Test. It allowed students to explore several variables over a short period of time. It allowed students to manipulate variables of their choice. Interactive Physics allowed students to track and explain the patterns that resulted from their chosen manipulated variable. After participating in this activity these students expressed an interest in sharing this experience with other students. They also indicated they would like to work with Interactive Physics on a more regular basis. As all four students said “When can we do this again?”
