It's Egg Drop Week!

Are you ready for some Egg Drops?!

(This original post was a link up!)
I took out the silly link up rules and just left the good stuff!


So, what have we been doing in our lab?

Let's talk about EGG DROPS!
STEM Egg Drop -Can you build a device to drop a passenger car the length of a five foot pole? Will your passenger survive (and it's an egg)?

I had this great idea about adding to a parachute type drop that we have tried in the past. The original version of this challenge was just to build a braking system for a dropping object.
Well, I added a scenario to the task about building a ride with an egg for the passenger.
Kids had to build the braking system with a way to also slow down the dropping passenger.

They had to use cups for the passenger cars. The team above actually built a parachute out of paper to help slow their dropped passenger.

 The team above used straws as a stopping platform.

Another straw platform!

Maybe just a sheet of paper will slow it down!

Here's a view of the entire device. It was a five foot drop with weight in the passenger car that was eventually replaced with an egg. We only had a few splats!

The one above was my favorite! One of the supplies was a piece of string, but it was too short to tie to the top and just have the passenger bungee jump to the bottom. So, this team connected straws to the string to make a long enough "rope" to use as a connecting cord. It worked!

This STEM challenge was, by far, one of the  best we have done. The kids loved it!

So, what are you doing in your Science class?

    1. We have had a blast dropping eggs. This week was all about parachutes! The one on this blog post was a version using a central pole for the drop. Kids have told me all week how much they loved this! Thanks for visiting and linking up!

  2. We do egg drops when we do space or energy. I take my pick. This week we are doing oobleck with second graders so I added what we are doing there. I wanted to show my cutie kinders trying to make craters on the moon...their footprints were all over my black carpet, just like the first moon landing, but I left that camera at school. Hope you get some linky friends to link up...I love to see other science ideas!

    1. Thanks so much, Renee, for linking up. We have had such fun with our egg drops! I just read your blog post and I am amazed at what you are doing with so many grade levels. It is tons of work, I know, to plan for so many grades! Thanks again!
