I am linking up with a great blog, 4mula Fun, for a linky of great secondary ideas and products!  Check out the rest of the links by clicking here. 

I added the link to my blogpost about the Blowing Big Bubbles Monthly STEM Challenge!  This is a great activity that can be made into a school-wide competition.  Who doesn't love bubbles once the weather gets hot and the school year is coming to a close...

We read the book, The Big Wave, by Pearl S. Buck during our weather unit and I never thought it would lead us into a quick mini-unit on clams, but the kids were fascinated by the fact that during some tsunamis the ocean pulls back from the beach and exposes all this sea like, including clams.

We researched the clam using the Internet and wrote information about them to start.  We have actually dissected quite a few different specimens this year, so the kids not only wanted to know about the external features of the clam, but also of the internal.  We colored the diagrams of the internal anatomy and then the kids had to make a clay model of the internal anatomy and this was quite a challenge!  They turned out great, though!

Once we learned all we could about the clam, we began our dissection of the clam.  It was really amazing!

This dissection was pretty simple.  I cut the abductor muscles (the muscles that make the shell stay closed) and the kids worked on finding all of the parts from the diagram.  The kids generated tons of wonderful questions as we worked through the mini-unit!

Who knew an unexpected topic could be such a great way to spend a week?  This is one reason why letting the kids' interests guide some of your plans is always a great idea!   We read, researched, wrote, diagrammed, measured, observed, questioned and more!

My students completed this STEM challenge this past week.  Building a geodesic dome with a bag of jelly beans and toothpicks is not that difficult, so I added a few more rules to up the challenge factor!

Question:  Can your group build the strongest geodesic dome using toothpicks and all of the jelly beans in the bag?

The kids found it really challenging to use all of the jelly beans.  I got the toothpicks and jelly beans (one bag per group) at the Dollar Tree.  Super cheap, super fun, and super challenging!

Here are some of our geodesic domes prior to testing them for strength:

As you can see, we had a wide variety of designs!  Some of these domes were able to hold five textbooks before collapsing!

You can use many different types of candy to build geodesic domes.  Why not try these with your class? Here is the link to the STEM Challenge pack, if you are interested!

Our school-wide monthly challenge for March is Gold Coin Catapults!  We have made catapults before, so the kids are getting pretty good at it.  We are also including a home project making Leprechaun Traps.  You can click here to get the Leprechaun Trap STEM Challenge FREEBIE!

We decided to pair this challenge with these two books:

This STEM Challenge needs very few materials!  You only need craft sticks, plastic gold coins, and rubber bands.  Click here for the link to this monthly STEM challenge.

Here are some of our catapult designs for this challenge!  Even though the kids come up with such different solutions, they all still work!   It is so amazing to see their thinking as they complete the different STEM challenges!

I just recently found this book and I am IN LOVE with it!  It is such a kid-friendly and educational book!  I can only hope that the author will continue to write these books for other regions of the United States!  I am currently working on a STEM pack to go with the book!  If you haven't already found this book, you can order it on Amazon!  You may want to check out the engineering challenge pack!

Here is the link to the STEM Engineering Challenge Pack for this book!  If you are looking for a pack with lots of bridge projects, this is a great one!

I stumbled upon one of the coolest things I have seen in a long time...INDOOR SNOWBALLS!  I just knew I had to create something STEM related in order to get to play with these in my classroom!  They come in 20 and 40 packs.  Click on the picture for the link to these on Amazon!

The students had to complete the following STEM Engineering Challenge:

Can you design and build a snowball catapult that launches the snowball the farthest distance?

Materials: (per group)

One indoor snowball (homemade or premade)
Variety of building materials (cardboard, paper, popsicle sticks, rubber bands, tongue depressor sticks, etc.)
Plastic spoons
Tape, scissors and glue
Tape measure

There were some pretty simple rules to follow as well, and the kids had a blast constructing their own catapults!  Here are some of their designs:

Students got to test their snowball catapults at their tables as they built them and then in the hallway when we were testing them.  They had a blast!  Click on the picture below for the link to the $2 lab pack.
