In fact, he couldn’t even look.įor our second trial, we traveled next door to our neighbors higher porch. Bones was not so sure about the next fall. After close inspection, they boys found their eggs survived the short fall. They measured the height of the step (which in hindsight we now realize we should have measured the height of our hands) and then Ready, Set, DROP!īoth boys were successful. So off we went to the front porch for our first experiment. The boys decided they wanted to test their contraption by dropping their eggs from 3 different heights. You can read more about it by clicking on the picture below. The boys (ages 6 & 8) set out to create their perfect contraption. The challenge was given to create a structure for a raw egg, that protect the egg from cracking at any height of a fall. Engineering The Perfect Contraptions for an Egg Drop This project was just the motivation we needed. I have always wanted to do an egg drop project with the boys, but all of our other projects seem to get in the way. The Creative Challenges are designed to encourage children to think independently through self-directed projects that encourage problem solving and creative thinking. In case you missed Part One of our Egg Drop Project, I will explain a little more about the Creative Challenges from Tinkerlab. Today I will share the science side of the project, but be sure to check out Hands On Play Party where I shared the invitation and the creations the boys made. You might not be surprised to find out that we turned this challenge into a Creative and Scientific Egg Drop Project. If you are a regular here, you know how much we love science around here. We love everything Tinkerlab does, so when Rachelle put out a call for participants to create with eggs, I got excited. (Example: When a jumbo egg was dropped from 5 meters onto a 1-inch foam surface, it fractured.Its time for another Saturday Science! This week is a special week here at Lemon Lime Adventures because we are taking part in Tinkerlab’s exciting Creative Challenge Project. In the supplementary exercise, questions are posed that require students to interpret the data from the simulation to make valid conclusions. They are given the task of defining the parameters necessary to reduce the force of impact on a dropped egg.Īnalyzing and Interpreting Data – Grades 9-12: Analyze data using computational models in order to make valid and reliable scientific claims. The NGSS calls for high school students to evaluate design problems using models and simulations, which is exactly what this activity lets them do. The accompanying multiple choice exercise asks students to analyze which experimental conditions result in optimal outcomes and why.įorce and Motion (HS-PS2-3): Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.Īsking Questions and Defining Problems – Grades 9-12: Ask questions that arise from examining models to clarify relationships. This conceptual exercise is designed to promote scientific reasoning as students examine the importance of controlling variables in experimentation. Set the initial conditions and watch the simulation – will the egg break, crack, or land safely? The Impulse-Momentum Change Theorem is used to automatically calculate the amount of force on the egg at impact. Select an egg size (small, large, jumbo), a drop height from 1-10 meters, and a landing surface (hard floor, 1-inch foam, or foam box). This simulated egg drop provides an engaging way for learners to mimic the iterative modeling process used by engineers in designing a product as they explore impulse and momentum.
