Legos and Simple Machines

Legos and Simple Machines We followed the directions in the book to make each simple machine.	Does this machine really work?
Joaquin, a classroom volunteer, helped us figure out how to put the Lego models together. Sometimes we don't think simple machines are very simple!	If we work as a team, we can rebuild it.
Making a rubberband powered car How does this work?	We made a racetrack on the floor of the classroom. How far will each of the team's cars go?
Let's try this again.	Teamwork: one person holds the string while the other one tries out the coat hanger daredevil.
Georgia, a classroom volunteer, helps a student try out the coathanger daredevil he made.	A student holds the solar panel in the sun and watches her car roll around the playground.
Joaquin, a classroom volunteer, holds the "track" while students watch a coathanger daredevil roll down it.
Solar Powered Lego Cars	Students prepare their solar powered cars for the race. Which car will win?
