Wind Power

In this activity, students will discuss the differences between the Bear Creek Wind Park and Bergey Windpower turbines. Students will learn the basic parts of a wind turbine and then build their own model wind turbine out of recyclable materials. Students will test their model wind turbines using three different-sized blades to determine which size harnesses the most wind.

Colorful Chromosomes

In this activity, students review how human physical traits, such as eye color, are determined by specific segments of genes. Students will use basic crafts materials to build a simplified model of a pair of chromosomes that represents some of their own physical traits. Then students will compare and contrast their models, to determine which traits are most frequently found among their classmates and therefore can be called high frequency traits.

Make a Speaker

In this activity, students will learn how an electromagnet works by making a simple one. Using this knowledge, students will design a diagram to make a working speaker using household materials. Then students will follow instructions on one method of making a speaker, and test their own designs to compare results.
