Air Cannons!

Posted March 6, 2021

We experience the movement of air every day, from our home heating system all the way to wind and tornadoes. To learn more about how air can move and affect us, Mrs. Riggin worked with her Fifth Grade students to design and build an air cannon. The students built the cannons at home and tested and modified in class to measure their success. #STEMatSLS

Paper Challenge!

Posted January 27, 2021

In Mrs. Cabreara's Science class, middle school students were presented with a variety of paper challenges after completing their Science test. What a creative, hands-on way to engage after a test!


bird's nest using the weaving method.
You do not have to build a nest like the
one in the picture. The requirements
are just that you use paper to create a
weave nest that can hold a small
stuffed-animal bird.
can you get your frog to leap the
farthest? When you are measuring, be
sure to maintain social distancing at all
times - just take turns!!!
example shown is of a butterfly, which is
symmetric. Your challenge is to make a
non-symmetrical real-life object (using
only paper) that can be balanced.

What Can you do with a Cardboard Box?

Posted March 22, 2020

Nothing sparks a child's imagination quite like a cardboard box! Recently Mrs. Schell’s Kindergarten students put this theory to the test. For inspiration, they read the book “"What to do With a Box" by Jane Yolen and Chris Sheban and then the kids took it from there and were off and running!

Using the 4 C’s of STEM: Creativity, Communication, Collaboration, and Critical Thinking, the kids talked about what they might create with their boxes, planning and assembling supplies and brainstorming about how to make their creations. They spread out across the classroom and came up with the most amazing projects. Everything from a doll castle to the solar system, a race car to a spacesuit, and a bat cave to a buddy bench – the kids did a magnificent job! Oh, what fun!
