Let"s store it simple!In this project, student must develop a contraption the can defend an egg from being crushed. The only materials they are enabled to job-related with are level wooden toothpicks and also wood glue. The force being applied to the egg contraption is in the form of a 5 gallon bucket falling from above. If you"re a teacher friend, continue reading below. If not... Don"t bother v the reasons for the experiment and skip to the funny part.You can examine out the videos on step 4 for a far better idea of what happens to the last product!Objectives: Student will certainly demonstrate capability to...1. Plan and also build a an equipment to safeguard an egg from pressures acting on it.2. Identify the pressures acting on your egg contraption and also build accordingly.3. Compare and contrast what worked vs. What didn"t work.4. Reflect top top what they would do differently.5. Collaborate in tiny groups transparent the process.6. Calculate the forces acting on their egg (momentum, force, acceleration, speed, velocity)7. Determine where Newton"s 3 legislations of motion have the right to be it was observed in the schematic of the experiment. This lesson can be easily differentiated. (less toothpicks, much less time to build, enhanced mass in the bucket, greater drop height... You obtain it) Students deserve to work in bag or go at it alone. I carry out not recommend bigger groupings.
You are watching: How to drop an egg without breaking it using toothpicks
The materials for this job are cheap and also easy come acquire. Because that the construct you will need...a. 200 flat wooden toothpicks. (I found the mass of 200 toothpicks is 11.3 grams. I measured the end 11.5 due to the fact that some toothpicks space bound to it is in bent / damaged / as well skinny... You can have the kids count them the end after you hand them the end if castle think friend shorted them. This method you don"t need to take time come exchange bad toothpicks)b. Lumber gluec. Wax paperd. Graph papere. 3.5 oz bathroom cup (I prefer plastic far better because they hold up because that multiple uses)Optionalplastic Easter egg, ruler, scissorsFor the check you will need...a. 5 gallon bucket (1)b. Egg (One because that each task built)c. A wheel (optional... Simply helps diminish friction)d. Rope (length depends on just how high her ceiling is)e. Massive to add to the bucket (I offered textbooks)f. A meter pole or garden stick come measure how high the bucket is when you drop it.
Here space the very first three points I tell my students.1. Imagine wherein the pressure is comes from. Where will you require the many support? Hint: A roof will NOT assist protect your egg.2. This is a 3 dimensional project. (You require to arrangement out the walls, build the walls laying level on the table, allow the walls dry, and also then stand the wall surfaces up and glue lock together. Make sure you check out the photo that shows what no to do.)3. Don"t waste your time and wait because that toothpicks to dry. There is constantly something you deserve to work on. I start course with a heat up (do now) on one of Newton"s Laws and also how it relates come the project. After ~ reviewing student generated responses, they can get their project and start / continue building. They will need a refill on glue at the begin of course each day.
When structure it is necessary to execute the following...Work on top of the wax paper.Glue toothpicks together.Let toothpicks dry.Protect egg at every costs!Below are some concepts my students come up with.

This is how I perform it. Friend are cost-free to modify.1. Place the egg contraption beneath a 5 gallon bucket through a predetermined fixed (I use 2 textbooks in the bucket).2, add some construction record beneath the contraption to make clean-up easier.3. Gently location the bucket on peak of the contraption. 4. Advanced the bucket 6 inches and drop that on the contraption.5. If the egg is still in tact, raise the bucket 12 inches and also drop the on the contraption.6. If the egg is tho unscrambled, progressive the bucket 18 inches and drop again. 7. Ns usually stop at 18 inches. If the egg survives from this distance, the project in mine mind is a success.
