Solar and Auroral Events
In this solar and auroral events worksheet, students answer 5 questions about a coronal mass ejection that traveled to the Earth. They find the time it took to arrive and they determine the speed of the coronal mass ejection in...
Project SMART
Exploring the History of Mathematics
Students research six different mathematicians using Internet resources. They examine the contributions of different cultures, women, and one that made a significant to geometry. They present their research to the class.
