We're Engineers!

 We had a lot of fun in science last week being "engineers" and building and testing cube designs for strength and stability. We tested the strength of three different "joiners". (marshmallows, puffed cereal and plasticine).  

Building and Testing

 This week we did a science experiment to test the strength of the Arch structure versus the Square shaped structure!

The arch held the most weight!

Building and Testing

We have started our new science unit: Building & Testing.  This week we tested the square shape vs the arch shape to see which shape held the most mass.  The square shape won!

Building & Testing

We've moved on to our Building & Testing unit.  Here are the students completing their first building challenge.  They were testing the strength of the arch design shape versus the square design shape.

Alberta Science Network & Building

We were lucky to have the Alberta Science Network back again.  This time Ms. Natallia talked to us about her career as an Engineer and all about building and testing materials.  She had an awesome hands-on activity for us too.  Each group built a crane out of popsicle sticks as well as a few other supplies, and at the end, we tested the cranes for strength and stability.
