What's Happening?
The blocks did not change. You did not add any new blocks. You did not throw any blocks away. But you made something completely different!
Big Ideas About Matter
Everything around you is made of matter (that means "stuff"). A block is matter. A LEGO brick is matter. A stick is matter. When you put pieces of matter together, you make an object — like a tower, a house, or a necklace.
Here is the really cool part: you can take apart your object and use the same pieces to build something brand new!
The Pieces Stay the Same
The Arrangement Changes
Let's Try It!
What You Need:
- 10 small blocks (LEGOs, wooden blocks, or even sugar cubes)
- A flat surface like a table or the floor
What To Do:
After you finish, ask yourself: Did the pieces change? Or did the way I put them together change?
What We Found Out
When you did the investigation, you probably noticed something important. The pieces stayed exactly the same. You had the same number of blocks. They were the same colors and shapes.
But the object you made was totally different! A wall looks nothing like a house. That is because you changed the arrangement — the way the pieces were put together.
This is true for lots of things in the real world. Let's look at some examples:
| PIECES | OBJECT #1 | OBJECT #2 |
|---|---|---|
| 🧱 Building blocks | Tall tower | Long bridge |
| 📎 Paper clips | A long chain | A flat star shape |
| 🧶 Yarn pieces | A braided bracelet | A woven mat |
| 🪵 Lincoln Logs | A cabin | A fence |
In every example, the pieces are the same. The arrangement is different. And the new object looks and works differently!
Do You See the Pattern?
Scientists always look for patterns. A pattern is something that happens the same way again and again. Let's see if we can spot a pattern here!
| WHAT HAPPENS | WHAT STAYS THE SAME | WHAT CHANGES |
|---|---|---|
| Break apart blocks, rebuild | The blocks | What you build |
| Take apart a bead necklace, make a bracelet | The beads | How beads are arranged |
| Unstack cups, make a new design | The cups | The design you make |
Do you see it? Every single time, the small pieces stay the same, but the object changes because the arrangement changes. That is the pattern!
This pattern shows up in nature too. Water can be a puddle, a river, or a lake. The water is the same stuff, but it fills different shapes!
People Use This Idea Every Day!

Words to Know
- Matter — Anything that takes up space. Blocks, water, and air are all matter.
- Object — A thing you can see or touch, like a tower, a chair, or a necklace.
- Pieces — The small parts that make up an object. Blocks are the pieces of a tower.
- Arrangement — The way pieces are put together. A different arrangement makes a different object.
- Reassemble — To take something apart and put the same pieces back together in a new way.
