1st-2nd Grades Science
Currently in science, the 1st-2nd graders are learning about muscles. This week we did an experiment to see if their muscles would get tired with continued use. They squeezed a small ball as fast as they could for one minute and recorded their results in their journal. They then repeated the experiment two more times. They found that the amount of times that they could squeeze the ball decreased with each minute that they did the experiment.
