Today year 2 conducted a science experiment about gravity. We wanted to find out how far a vehicle would travel on certain surfaces using a ramp and the pull of gravity. We positioned our classroom tables in rows of 3 tables with each one having a different surface. The 5 surfaces we tested were sand, thick fabric, bubble wrap, thin netting and a plain wooden table. We found out that the plain table and thin netting allowed the vehicle to travel the furthest.
