Roller Coasters

We had the privelage of visitng the middle school this week and learning all about how they made their roller coasters.  When I asked the students what they learned about they said:

Mass

Gravity

Energy

Velocity

an so much more!  

They have been creating roller coasters in the classroom ever since this day.  They talk about the mass of the marbles and the weight to make sure the energy created will be right for the track!  I love how students learn from eachother!!
