Week 36- Refraction, Engineering Challenges, & Pentominoes

This week we did a little experiment to see how refraction works. My students put a penny under a cup and then filled the cup with water. 

Refraction makes the penny disappear! 

I divided my students into groups for the House of Cards Engineering Challenge. Smart-Chick on TeachersPayTeachers has several great engineering challenges.

Each group got a deck of cards and a pair of scissors. Their goal was to build the tallest free standing structure. I loved seeing them work to find a solution to make their structure the tallest.

I also think my students really loved doing this! 

The tallest structure of the day was from Skyler, Jared, and Evan. Their tower was 31 inches tall.

Then I had them stretch their brain in math. We pulled out the Pentominoes and had them work to create as many different 3x5 arrays using different combinations of 3 of the pieces. 

We only have one more week of school left before summer break. I can't believe it is coming to an end. I have some more fun activities planned for the last week of school, along with awards day and field day.


  1. I am so glad the kids liked the engineering challenge! They are amazing! The tallest tower is impressive (and so are the others).

  2. Love the engineering challenge! I want to try that with my kids next year. Thanks for sharing!
