Internet Lesons
|
| Are You a Square? |
Students will measure their arm span and height, collect data from the rest of the class and draw lines of best fit (trend lines) first by hand and then with the use of Excel. They will calculate the equations of the lines and use these equations to predict conclusions. They will look at trend lines for two other sets of data given in a spreadsheet. Meets Arizona State Technology Standards 1 and 3. |
| Bringing the office into the 21st Century |
Studens will design the system for an office of six people and then write a report, defending why they used or did not use networking. Meets Arizona State Technology Standard 2 and 5. |
| Desert Island Dilemma!-Who's at Fault? |
Students will solve a problem by using trigonometry. They will graph and obtain the equation of a wave. They will calculate amplitude, period, frequency, and phase-shift to determine if the wave is within certain parameters. This will determine if the skipper and first mate are responsible for the shipwreck during a storm. Meets Arizona State Technology Standards 3 and 6 |
| Fact or Fiction? |
This activity helps students evaluate the Internet. They take a pre- and post- test to see how much they know and learn from the lesson. The students produce an article about an obscure town that contains facts and believable fiction. Peers will try to determine which parts of the article are fictions. Meets Arizona State Technology Standard 2. |
| Internet Safety |
Students will take a pre and post quiz on Internet safety. After discussion through a Power Point presentation, the class will come up with a workable contract for using the computer and Internet safely. Meets Arizona State Technology Standard 2. |
| Quadratic Equations |
Students will identify quadratic expressions and equations. They will solve quadratic equations using 3 methods. They will determine the nature of the roots using the discriminant. Students will produce a document/pamphlet explaining how to solve a quadratic equation, for another student. Meets Arizona State Technology Standards 1 and 3. |
| Stack of Cups |
Students use their mathematical skills to create a linear regression in Excel using everyday data. They will determine rate of change and present their findings. Meets Arizona State Technology Standard 1, 3, and 6. |
| The Great Egg Roll X2 |
This is an on-line project sponsored by Crossroads Christian School. The students will roll a hard-boiled egg, measuring the distance rolled. They will find the average length of a roll. The data from several schools will be used to do data analysis. The students will also roll a plastic egg (optional), the challenge is to make it roll the same distance as the hard-boiled egg. Project runs from March 8-April 26, 2002. It is done every year around this time. |
| Theorem Investigation |
Students will investigate whether they can expand Hero’s Theorem and Brahmagupta’s Formula to find the area of any convex pentagon/hexagon. They will present their findings in a professional document. Meets Arizona State Technology Standard 6 |
| Walking The Square |
You will need to have access to Cox Ed Net to do this lesson. |
| What is a Vector? |
Students will use the Internet to find out about vectors. They will investigate how to add vectors in two and three dimensions, using several methods. They will learn how to do the inner (dot) product and cross product and know what the solution means. Meets Arizona State Technology Standard 5. |
| When the Cookie Tumbles |
This is an on-line project sponsored by Crossroads Christian School. It is done during September / October of each year. Students around the world will stack Oreo cookies until the stack falls. Each group will have 3 attempts. The highest number from each group is sent to the coordinator to be tallied. Students will access the data for data analysis. Each group will make a Web Page about the project and data collected. Look for “Loop de Loo” with Fruit Loops in January. Meets Arizona State Technology Standards 3 and 4. |
