January 11, 2011

The kids also learned about the two forms of energy- kinetic and potential.  They were given various materials; ruler, craft sticks, clay, spoon, rubberbands, and marshmallows to create their own catapult. It was interesting to see all the different ways they came up with to build one.  Watch out for the flying marshmallows!!!


      Busy day here!  We have completed another experiment to help our understanding of friction as well as Newton's 1st Law (an object will stay at rest until acted upon by a force (push or pull)).  The kids made a hypothesis about whether a marble would roll further on a hard surface, like our floor, or a rough surface, like our rugs.  They then tested their hyposthesis by creating a ramp and rolling a marble to measure on which surface created the most friction causing the marble to stop.  They discovered that the rugs, by far had more friction.  This is one of the many things we will be doing in our inquiry into forces and motion.  Our final project...{drum roll please} will be to create a roller coaster!! They are super excited about that one!  But to be sure we can create the best roller coaster out there we really need to understand how forces and motion work together.   Sorry those pics are crooked...
