Students (along with their families) were challenged to create a contraption that would protect a raw egg dropped from the top of our gymnasium, about 25 feet high. Families were charged to experiment with density, velocity, inertia, and gravity, using their knowledge of the scientific method. Without using any technology intervention, students had to design a contraption using materials that were already on hand at home. Students documented the process through notetaking and illustrations of their design, and explanations of why they believed their egg contraption would work. Twenty-three students tested their designs at various heights at their homes and made necessary modifications. Scientists are not always successful on their first attempt; just ask Thomas Edison.
In addition to the design and testing process, students had to develop a marketing flyer or advertisement about their egg contraption.
At 1 p.m., more than one hundred students and approximately 40 parents and grandparents cheered on the budding third grade scientists. With the help of Dr. Fry on the gymnasium roof, the third grade students had 30 seconds to open their contraption and reveal their raw egg. Students and families cheered louder on every egg drop success. About 81 percent of the eggs survived the impact.
In a group discussion afterwards, students analyzed what materials were most successful in reducing force, and transferring the kinetic energy into potential energy. Students concluded that bubble wrap, rice krispies, popcorn, and marshmallows provided great cushion for the egg. Students will re-analyze their paperwork and discuss what modifications they would make in the future.
We are so proud of our egg-cellant third grade scientists!
For the 2016-17 school year, Good Shepherd School is planning to invest in a new K-8 science curriculum to bring even more hands on learning experiences like this to our students. Contributions to the Good Shepherd School Fund and grant funding will be used to purchase this new program that will benefit all of our students beginning next year.
