Young Engineers

This year we are excited to "elevate" our science knowledge as we dig in to our new Science curriculum (Elevate Science) from the Savvas Learning Company.  We are so happy to continue partnering with Mr. Pytleski once a month again this year with a connecting STEM activity as well. The first topic we've been learning about in 2nd grade is Physical Science: Properties of Matter.  Last Tuesday, we started working through our first Investigative Lab.  To build the anticipation of our first project, we discussed how beavers can teach engineers to help design dams to change the flow of water. Then we drew "lucky duck" sticks to determine our partners and spent a few minutes brainstorming ideas and even drawing our model designs.  On Wednesday, each team set to work to see if they could build a dam that would change the way water flows and hopefully hold most of the water back.  Each group was given a tub of supplies which included popsicle sticks, pipe cleaners, a glue stick, modeling clay, and scissors.  Everyone had amazing conversations and ideas and some learned to remain persistent and keep adjusting their plans.  We looked at pictures of real dams, like the Gavins Point Dam in Yankton, SD and even found a picture online of our local dam at Island Park here in Rock Rapids.  On Thursday, we tested our models and it was so fun to hear all of the excitement and anticipation.  After testing 7 dams, we only had one model that held the water back completely.  However, we learned that if given the chance to repair our dams, we would have sealed the sides and the bottom better as water is able to sneak through even the tiniest of spaces, especially when pressure and gravity are forcing the liquid downhill.  Be sure to check out our pictures below as we take you through our building and testing process. Science sure is FUN!

We are engineers!
