The Daring Disasters of Ethan Flask and Professor Von Offel
(The fourth book in the Mad Science series)
A Chapter Book by Kathy Burkett and Anne Capeci
There's stormy weather at Einstein Elementary! Outside the school, thunder and lightning are raging. Seems like the perfect time for Mr. Flask's science class to study about natural disasters. But while his sixth-graders are doing experiments about tornadoes and earthquakes, an even bigger storm is brewing down the hall! Looks like the awful Professor von Offel is up to something. And lab assistants Alberta, Luis, and Prescott are determined to find out about the mysterious winds swirling around the professor!
