Today in science we are continuing to work on the forces push and pull.  We pushed and pulled a light and heavy box through a tape obstacle course.

"When you pushed the box your arms were straight.  When you pulled the box your arms bent." Jacob
"The lighter the box was the easier it was to push and pull." Emma
"It was harder to push and pull the box when it was full of books because the mass was greater."Bailee
"Your back was straighter when you were pushing."Levi
"When the box was full it was hard to steer the box around the curves."Jude
