The Effect of Medications on Daphnia 

Medications are being found in our rivers and lakes. Will these chemicals affect the plants and animals that live in our waterways? This activity looks at the effect of these medication levels on the fresh water animals, daphnia.

Biology Description
The Effect of Medications on Daphnia Medications are being found in our rivers and lakes. Will these chemicals affect the plants and animals that live in our waterways? This activity looks at the effect of these medication levels on the fresh water animals, daphnia. The Stella model simulates the research conducted by Colleen Flaherty of the University of Wisconsin-Madison.

How Does a Hair Know, How Long to Grow Students use a Stella model and measurements of their own hairs (scalp, eyebrows etc.) to discover how hairs regulate their length and also the growth rate of their own hairs.

Physics Description
Ohm's Law Using a computer model of a circuit board the students construct simulated series and parallel circuits to discover Ohm's Law.

Mathematics Description
Sieve of Eratosthenes This computer model of the Sieve of Eratosthenes helps the students find prime numbers by systematically eliminating multiples from a range of numbers.

RSA Cryptology This computer model allows students use prime numbers to encrypt and decrypt messages using the RSA method. The internet uses RSA encryption to make your online credit card purchases safe.

Modular Mathematics 14 divided by 4 = 3 with a remainder of 2. In modular arithemetic this is expressed as 14 mod 4 = 2. This activity allows the student to explore and practice modular arithemetic.

Environmental Science Description

Will Global Warming Push Trees to Extinction? The EPA estimates that for each 1 degree of global warming the average temperature for an area will move north 100 miles over the next 100 years. Deer can walk north to stay in their prefered temperature range. People can adjust their thermostates. What will happen to trees? Using this lesson's computer models and information from the internet the students can predict which trees of your area will be threatened by extention.

Surface Water Runoff Modeling Using an Excel spreadsheet model the students are able to calculate the runoff from a field or neighborhood. The model allows the students to adjust rainfall, soil type, and ground cover.

Rain Gardens When we develop a field from forest or farmland to urban or industrial use we change the storm water runoff. Using an extention of the Excel model used in the Surface water runoff lesson the students are able to calculate the "rain garden" area needed to sequester and absorb the additional runoff.

How to Weigh a Tree and Calculate its Carbon Using an Excel spreadsheet and measurements of at tree outside your window the students are able to calculate the trees weight. Through a series of calculations the Excel model also calculates the CO2 that our tree has sequestered. The model also equates this sequestered CO2 to gallons of gasoline burned, kilowatts of electricity...

Forests, Mining Carbon from the Air Using a University forestry model, the students simulate the growth and management of a forest. The model monitors the movement of carbon into and out of many different parts of the forest: branches, trunks, roots, soil, air, wood products, etc. By adjusting the management and recycling variables the students are able to discover the forest's role in atmospheric CO2 levels.

Forests Fire Students read a report that explores forest fires using the "Fire!" model. They then conduct their own experiments using the model to build on the work of others.

Peppered Moths Using Excel spreadsheet, Stella and NetLogo models, the students examine the last 100 years of research by scientists to explain why Peppered moths have changed from white to black and then back to white again.

Astronomy Description
Predicting lunar eclipses The students create a spreadsheet to predict lunar eclipses. In the process they discover the Saros Cycle which the ancient Babalonians used to predice lunar eclipese thousands of years ago.

Calculating Orbital Speeds Create a spreadsheet that calculates the fastest and slowest speeds of the moon or any other body that orbits the Earth or sun.

Medicine and Biosciences Description
Flu Using a Stella model of a flu epidemic the students devise a sick leave policy for a company in a small town. Thier task is to reduce the company's expenses for lost productivity and/or sick leave pay.

Calories The students calculate the base calories they need and also the calories they need because of the activities they engage in. Then they compare the calories they use with the calories they consume.
