WPS Pre-K Egg-cellent Experiments

3/26/2026

Berlin, MD – Leading up to the Easter holiday, Worcester Preparatory School's (WPS) pre-kindergarten class conducted two experiments using eggs as the key ingredient. Both experiments led to a day of fun as students learned about the force of gravity.

In the "Inertia Egg Drop Experiment,” the Law of Inertia was tested. In this case, the egg remains at rest until the plate is moved, allowing gravity to take effect. This causes the egg to drop straight down into the cup, as there is no force to change its direction. Next, in the "Humpty Dumpty Egg Drop Challenge," students, with help from their parents, created parachutes from household supplies to protect a hard-boiled egg during a fall and landing. The students dropped their parachutes from the top of the playground equipment to find out if the egg stayed intact.

Founded in 1970, WPS is a private, independent school serving pre-kindergarten through Grade 12, located in Berlin, Maryland. Approximately 500 students attend from Maryland, Delaware, and Virginia. For more information about WPS, please visit www.worcesterprep.org or call 410.641.3575.
