Fold it!

Science this week? We learned that materials are stronger when folded or twisted!

We were asked to make a bridge using paper balanced on two cups. Only a few blocks and our bridge began to sag.

As scientists, we first listed our materials and checked them off as we collected them.

Getting Organized

Then we folded the same paper like a fan and tried balancing cubes again.

What a difference a few folds make!

Some of us were determined to balance 100 cubes? No way?! Well, Raymond had the record at 87!

So what did we conclude? We figured that the folds made little triangles (like you see in corrugated paper) and that triangles are the strongest shape. We learned this last week (see here)!

Strength of triangles!

Marshmallows, tooth picks and a challenge! Make a cube. How many blocks can you balance on a single card?

Step one: Make the cube

Step two: Start balancing

Step three: Detect a problem? Yes, definite leaning!

Step four: Get four more toothpicks and . . .

Step five: Give credit to the triangle! It is the strongest structure!

Our week in pictures

Life has been busy at Seymour School! But lots of great learning and working together has been going on. Some highlights of the past week!

Buddy reading with our little buddies in Division 7 (K/1) is always a highlight of our week. This week we broke out the rhyme and repetition bin and enjoyed the repeating parts of stories we could share together.

Sometimes books call to you, "Come into the story!"

In math we have been working on skip counting. We find that physically moving numbers into sequence helps us practice the patterns really well. With 25s, we chanted “25, 50, 75, double zero!”

Follow the pattern!

Our reading group shared a fantastic book called Clever Beatrice written by Margaret Willey and illustrated by Heather Solomon.

Clever Beatrice

As we read, we charted the character traits we noticed in Beatrice and at the end of the story, took turns sharing examples from the text that illustrated each point. Soon, we will be doing this with a partner and then eventually, on our own,  as we read a picture book.

Character Web

In Science, we have been studying structures. Today we learned some new vocabulary to help us talk about bridges: approaches, foundation, supports and span. The task was then to build a bridge using just blocks and rulers.

This group attempted to make the longest bridge possible and even test drove matchbox cars up the approaches and along the bridge.

Straight and long!

Another group wasn’t interested in the longest bridge, they were all about interesting! This bridge had multiple approaches and reinforced supports. (And options for multilane traffic)

All over the classroom, bridge construction and team work could be observed. The adults loved listening to small group presentations about bridge design and how the groups worked together. One self assessment: “Next time, I will work harder at team work.” We really do depend on each other!

Bridges everywhere you look!
