2nd Graders Test Eggshell Strength in Science Experiment
Julian Corbett

How many dictionaries can four eggshells hold? Second-graders in Grammar School science teacher Claire Rose’s class put that question to the test in an exciting experiment last week. While their teacher set up the experiment remotely via Zoom, Ms. Rose’s young scientists used their previous knowledge and best guesses to estimate how many books the eggs would hold. Some students hypothesized the shells would break under the weight of just one dictionary, while others guessed it could hold as many as four without any problem. 

After comparing hypotheses, Ms. Rose began the experiment. One by one, she stacked the dictionaries on top of the eggshells. In the end, the class found the eggshells could hold a lot more dictionaries than they had imagined.
