LO: SWBATdemonstrate that small units can be
combined or reassembled to form new objects for
different purposes and explain the materials chosen
based on their physical properties.

DOL: Given scenarios, SW correctly explain that small
units can be combined or reassembled to form new
objects in at least 3 of 4 questions.

2.6C Demonstrate that small units such as building blocks can be combined or reassembled to form new objects for different purposes and explain
the materials chosen based on their physical properties.

Building New Objects with
Small Units and Physical

Properties

Exploring How We Use Different Materials

E NGA GE

What can we make from smaller
pieces?

Have you ever used blocks or

LEGOs to build something new?

Can you guess what larger objects
these could create.?

I think we can build ___ from these
pieces.

Can you think of something
at home that is made from
smaller parts?

A playground might have
swings, a slide, monkey bars,
and a bench. It might use
metal, plastic, wood, and
rubber. The materials are
chosen based on their
properties. The properties fit
how the parts are used.

1. Look at each part of the playground. Tell about the

materials that make up each part. What is each part
made of?

2. Design your own playground. Think about the best

materials for each part. Draw your playground. Label
the parts and write what the parts are made of.

3. Explain the materials you chose based on their physical

properties.

4. Compare your playground design/playground with

others.

12

How can you make a model of a playground?

Materials
craft sticks

rubber bands

clay

chenille stems

small cups

blocks

foam sheets

construction paper

aluminum foil
tape or glue

1. Use your design plan and the

materials provided to create a
model of your playground.

2. Why did you use each material

for your model? Explain why you
used each material for your model.

We used the ______ for the _____ because it is _______.
_______ is a good material for a______ because _____.

13

How can matter be combined?

What problem does the engineer in the
text need to solve?

EXPLAIN

15

Engineers use different materials to make
objects to serve a purpose. They use the
physical properties of materials to decide which
materials to use.

When small pieces come together,
they can form new objects. This is
called combining.

Small pieces come together to form ________.

Wood

Bricks

Why do we choose certain

materials for different purposes?

We choose certain materials because ______.

ELABORATE

19

How can you reassemble pieces to make
something new?

An artist reassembled pieces of dishes to make a
wall. Reassemble means to put pieces together
again or in a different way to create something new.

Why do you think we use
wood for building houses

instead of rubber?

We use wood for because _______.

21

Think about the object that is made of smaller
pieces or more than one material in the
classroom or your house.
Write about the properties of the object’s
pieces.

DOL: Given
scenarios, SW
correctly explain that
small units can be
combined or
reassembled to form
new objects for
different purposes in
at least 3 of 4
questions.
