Students were tasked to support a tower of heavy math books two inches high with only two sheets of paper and a small strip of tape.
The students tried a few methods and discovered the highly effective cylinder supports. While 12 inches was the official record, some creative students (cheaters) built the masterpiece below.
We used the classic "Traveling Trains" problem to learn Systems of Equations.
In a cross curricular lesson of Science and Algebra, students created balloon powered cars and then calculated it's speed or "slope". We then paired up the cars and the students had to use the equations they created for their car to calculate the exact point when the two cars would pass each other or collide (intersection point). In their Science class, the students focused on the laws of energy and motion. Enjoy.
