Topic:
2.Structure and Properties of Matter
Performance Expectation:
2-PS1-2. Analyze data obtained from testing different materials to determine which materials have the properties that are best suited for an intended
purpose.
Disciplinary Core Idea:
Science and Engineering Practice: Cross Cutting Concept:
Literacy:
Different properties are
suited to different purposes.
(2- PS1-2)
Analyze data from tests of an
object or tool to determine if it
works as intended. (2-PS1-2)
RI.2.8 Describe how reasons support specific
points the author makes in a text.
Simple tests can be designed to
gather evidence to support or
refute student ideas about causes.
(2-PS1-2)
W.2.7 Participate in shared research and
writing projects (e.g., read a number of
books on a single topic to produce a report;
record science observations)
W.2.8 Recall information from experiences
or gather information from provided sources
to answer a question
HOT Questions
1. How do properties affect the intended purpose of an object?
Math:
MP.2 Reason abstractly and quantitatively.
MP.4 Model with mathematics.
MP.5 Use appropriate tools strategically.
2.MD.10 Draw a picture graph and a bar
graph (with single-unit scale) to represent a
data set with up to four categories. Solve
simple put-together, take-apart, and
compare problems using information
presented in a bar graph.
Learning Target: “I Can”

At the end of the investigation, students will choose one property and write
how the property affects the intended purpose.
Activities:
Investigation (Teacher Planned, students will test, analyze data, & discuss intended purposes of objects)


Have paper & metal to simulate bridge, which would be stronger?
Have shoes with different type soles, or different sports balls, which is more flexible?



Paper & sponge, which is more absorbent?
Construction paper & sand paper, to discuss texture.
Writing on a pillow or table, to discuss hardness.
Website for students to investigate materials and their intended purpose.

In small groups students can work together to create posters to show why objects are made of intended materials. For example, on one side of the
paper a water bottle is made of plastic because … On the other half of the paper, It is not made of cloth because … (to show why, with
illustrations)
