Introduction
We are going to look at different things and see how they are put together. We will observe all the pieces of an item and see how and where they are placed in that item. Once we have a good understanding of how one item is constructed, we will take the whole thing apart. With all the different pieces you have from the original item, I want you to make something new and different! You can only use those same pieces, though. You can't add any additional pieces.
Task
With your partner, you will make several observations of an item. I want you each to sketch the item in your interactive journal. After you've made your sketch, you will take the item apart and construct something completely different and new. You will also draw this in your interactive journal.
Each of you will complete a graphic organizer. This will be a little more in-depth than your interactive journal drawing. On your graphic organizer, I want you to draw each piece of your new item, write what it will be used for in your new item, and what properties make it work effectively in your new item.
Are you ready?
Process
Let's start with this video.
Let's learn a little more about what makes up things.
We want to look at not only constructing a new item, but also effectively constructing a new item out of your existing pieces. When you look at the different pieces that make up your items, I want you to decide how the properties of these things make them perform their "job" well. Then, I want you to think of what else this piece could be used for and why the properties of this this piece would make it a good fit in your new item. For example, we wouldn't want to use marshmallows for the foundation of a house because marshmallows are not strong.
As you're taking your original item apart, draw the different parts or pieces you have and list the property that makes that a good piece for that item in the first box on your graphic organizer. In the other box, I want you to draw those same pieces with those same properties, but tell me how you are going to use them in your new construction.
GRAPHIC ORGANIZER
After you have completed your graphic organizer, you may start on your new construction.
Evaluation
You've all done so well with your graphic organizers! Now, you can start your new construction!! Be sure to construct how you drew your picture. If you make any changes, it needs to be changed on your graphic organizer!
Conclusion
Congratulations! You are all master re-constructors now! You have all done so well today! Talk with your partner and tell them what you've learned today!

Make observations to construct an evidence-based account of how an object made of a small set of pieces can be
disassembled and made into a new object.
Science and Engineering Practices
6. Constructing explanations and designing solutions:
Constructing explanations (science) and designing
solutions (engineering) in K-2 builds on prior
experiences and progresses to the use of evidence
and ideas in constructing evidence-based accounts
of natural phenomena and designing solutions.
• Make observations (firsthand or from media) to construct
an evidence-based account for natural phenomena.
Disciplinary Core Ideas
STRUCTURE AND PROPERTIES OF MATTER
Different properties are suited to different purposes.
(LE.PS1A.a)
A great variety of objects can be built up from a small
set of pieces. (LE.PS1A.b)
Cross-Cutting Concepts
ENERGY AND MATTER
Objects may break into smaller pieces, be put together
into larger pieces, or change shapes.
