Last year was such a huge success that the Fairbanks School District has asked for an encore! This year's projects are:

**Atmospheric Science**

Presenter: Derek Starkenburg

How fast will the temperature change? Will I need a coat today? Learn how meteorologists calculate the rate of change of temperature as a cold front blows through your neighborhood!**Walrus and Sea Ice**

Presenter: Olivia Lee

What can you tell about sea ice from its shape and size? Learn how to estimate the size of ice floes using simple geometry and calculate how many walrus can safely float on an ice floe.**Just How Big Were Ancient Predators?**

Presenter: Danielle Serratos

Learn how Paleontologists use clues from the past like teeth and footprints of dinosaurs and extinct sharks to figure out how large these predators were!**Wind Power**

Presenter: Patrick Wade

The power that can be captured from the wind is directly proportional to the area of the device that is capturing the wind. There is a limit to the amount of energy that can be captured, known as the Betz limit. We will be demonstrating how much energy can be realistically captured from the wind.**Economics of a Lemonade Stand/Wealth Creation**

Presenter: Howard Sparks

How can math be useful for planning and operating a lemon stand? Well math turns out to be very important for figuring out how much lemonade you'll need to sell. How do economists figure out the value of things? This experiment will show you one way that you and your classmates value bags of goodies.**(Hour of Code)/2**

Presenter: Samantha Wuttig

Learn about the basics of computer programming and the importance of computer science. Bring your iPad to learn how to make Angry Birds and Plants vs. Zombies move on your screen.**Measurements and Estimations**

Presenter: Denise Thorsen

What happens when 70 students measure the same object? Do they all get the same measurement? What does it mean if they don't? If I take a sample measurement of the number of caribou in a herd or the number of stars in the sky can I estimate the total number of caribou or starts?

On April 23, the Fairbanks North Star Borough School District in collaboration with the Alaska Space Grant Program presented "Math Day on Campus" at the University of Alaska Fairbanks for 6th grade students who are in a pilot program for highly advanced math. Approximately sixty students from six different schools participated in this all day event focusing on the application of mathematics in different fields of study. Four different colleges and schools at the university showcased how they use math through the following projects:

**School of Management (SOM):**

Will a lemonade stand make money? Using special techniques we will show you how to predict how much lemonade you will have to sell to make a profit!**College of Natural Science and Mathematics (CNSM): **

How big were ancient sharks and dinosaurs? Learn how to calculate body size of ancient creatures from clues like fossilized teeth and tracks.**School of Natural Resource and Agricultural Science (SNRAS): **

Fractals in Nature: What are fractals? How are fractals used in science and industry?**College of Engineering and Mines (CEM): **

How does a robotic mouse figure out how to get through a maze without being able to see the entire maze at once? How much does it cost to make yourself toast in the morning, make a smoothy after school, or blow dry your hair?
