Speedy Lab: Calculating Speed and Acceleration

1/23/2018

0 Comments

 
           Today we raced! Students ran and race-walked across the gymnasium, while their peers timed them at distances of 20, 40, 60, 80, and 100 feet. 
         Once we had all of our data recorded, we began to analyze it by calculating speed from the distance and time measurements.  
            Tomorrow we will graph and further analyze our data as well as conclude our lab.

As we study what it means to be human, we are looking at different changes and events throughout the 250,000 years of human history. We are starting with the development of tools and technology that resulted from ever increasing collective learning among humans. Students built atlatls and threw darts on the football field to get familiar with an ancient hunting technology that allowed our ancestors to hunt the mega-fauna of the ice-age. Atlatls continue to be use around the world for hunting and fishing. If you want to make your own atlatl with simple materials the directions are below.
