For Science today we were looking at the amount of "pull" force it would take to set a full water bottle in motion.  We used washers as our pull force.  Then once it had moved we looked at how many more it took to more it more.  We all got very different results.  Then we brainstormed what were the possible differences in our experiment.  You should have heard their amazing insights.

"When my tables water bottle was at the one measurement it only took one more washer to get it to move to the number 4 measurement."Jude
"We used less washer to move bottles that had a little less water."Laura
"The bottles with less water used less washer to pull the bottles."Riley
"If you dropped the washer into the cup from a high height it move quicker than if you carefully put them into the cup."Jacob
"Our tables water bottle did not inch along the measurement page it flew off the table because we were dropping the washers from a high height."Bailee
"The more washers you put in the more distance the bottle moved because the "pull"force was stronger."Ian
