Probability How Likely Is It? Page Views: 2987

Throughout our probability unit, we have discussed what it means to determine how likely an event is, based on given parameters. We talked about experimental and theoretical probabilities, and we even acted out some situations to study probabilities, patterns and outcomes. To wrap up this unit, students will be completing a project either individually, or with a partner. This is different from most projects, though, in that STUDENTS get to pick what the topic is! Based on what we have learned so far, what interests students, and interactive tools available online, students will be choosing a situation, its parameters, and a desired outcome, and will ultimately study the probability of that outcome by utilizing some cutting edge technology. Whatever topic students choose to study, they must include ALL of the following: (1) An explanation of their topic, its parameters, and the desired outcome. (2) Students must explore interactive sites online to find a tool to simulate their situation. o Example: If I am studying coin tosses, I would need to find a simulation of a coin toss online. o See below for suggested websites to explore. (3) Students should simulate their experiment a MINIMUM of 30 times online, and record the data in a spreadsheet using Excel. (4) After collecting their data and documenting it in a spreadsheet, students should use the formula tools in Excel to calculate the totals for each possible outcome, AND the averages of each possible outcome. (5) After completing the calculations described above, students will use Excel to create a bar chart AND a circle graph to display their conclusions. (6) To share their findings with the class, students need to create a Glogster poster online. This poster should include… o Their topic and parameters. o The 2 charts from Excel. o Links to the interactive sites used online. o Conclusions about the experiment. (7) When finished with the poster, students need to do 2 things: 1. Email the teacher a link to the poster online. 2. Post a link to the poster on a class wiki. (8) Finally, when all parts of the project are completed, students will share with the class their topic, how they simulated the experiment using cutting edge technology, and conclusions found. If working with a partner, BOTH students must share some information! ***If needed, students should be given short tutorials about how to use Excel functions, Excel charts, and the Glogster website. Students should have class time to work on this project, but some work might be homework. ________________________________________________________________ _________ InteractiveProbability Websites
Below are numerous interactive sites that would be appropriate for this lesson. They are categorized by URL address, and I have included short descriptions of the manipulatives on each site that might be useful.
Students are NOT limited to these websites, but they are a start. If students find a website not listed below, please check with the teacher for approval.

1. Advanced Fire Run a simulation of how a fire might spread through trees, learning about probability and chaos. Track the results of multiple burns and use the data to draw conclusions. 2. Adjustable Spinner Create a spinner with variable sized sectors to look at experimental and theoretical probabilities. Parameters: Sizes of sectors, number of sectors, number of trials. 3. Advanced Monty Hall Choose one of “N” doors to determine the odds of winning the grand prize behind that door, similar to the TV program "Let's Make a Deal." Parameters: Number of doors, number of trials, staying or switching between the two remaining doors. 4. Coin Toss Simulations of a coin toss allowing the user to input the number of flips. Toss results can be viewed as a list of individual outcomes, ratios, or in a table. 5. Crazy Choices Game Compare theoretical and experimental probabilities, using dice, cards, spinners, or coin tosses. Three different probabilities can be compared at once. Parameters: Type of probabilities, number of trials. 6. Dice Table Experiment with the outcome distribution for a roll of two dice by simulating a dice throwing game. Parameters: Which player wins with which total rolled. 7. Experimental Probability Experiment with probability using a fixed size section spinner, a variable section spinner, two regular 6sided dice or customized dice. 8. Marbles Learn about sampling, with and without replacement, by randomly drawing marbles from a bag. Parameters: Number and color of marbles in the bag, replacement rule. 9. Spread of Disease Models how a population of susceptible, infected, and recovered people is affected by a disease.

Comments 
Depending upon student resources at home (i.e. computers, internet, spreadsheet software, etc.), this might need to be an activity completed entirely in school. 
CrossCurriculum Ideas 
This math experiment connects closely with the scientific method. Students are formulating a question, predicting/considering outcomes, experimenting, and drawing conclusions. 
FollowUp 
To continue the topic of probability, students can contribute questions/comments regarding their probability experiment to a class wiki that classmates can respond to, and explore.
