Transforming a Circle

You can find the areas of different polygons by dissecting the polygons and rearranging the pieces into a recognizable simpler shape. Cut a circle into wedges and fit them together to form a crude parallelogram.

Trigonomic Functions

Use a trigonometry calculator to explore the ratios of sides of a right triangle. Do the sine, cosine and tangent have maximum or minimum values?

Tulip Gardens

Track tulip growth as the season changes from winter to spring. See how temperature, rainfall and sunshine affect growth and help scientists look for patterns of climate change.

Units and Prefixes

Explore some common units and prefixes in the metric system. Then decide which metric units you would use to measure several displayed objects.

Unity and Diversity
