Parachutes
Each
group plans how to redesign the activity to meet more of
the criteria.
Then
they try out their plans.
This
group decided to test the variable of how different materials
would effect how well a parachute floats. They made one out
of crepe paper.
Then
they dropped them both parachutes from a balconey to compare
them.
Groups
go back and forth between planning
and
testing their plans
