Lesson/Unit Plan

Overview:

In this lesson, students will be able to explain that the parts of an object can be rearranged to create a new object. Students will also get a sense of the number of different objects that can be created from a small number of parts and will apply this to modeling atoms and molecules.

Student groups are given four snap cubes and guided to use the four cubes to make eight different objects. Each student is given a picture of one of the possible 29 different objects that can be built from five snap cubes and students build their object. After students build their objects, all 29 are displayed for the class to see. Students do an anagram activity to see that letters can be rearranged to make different words, just like atoms can be rearranged to make different molecules.

Content Standard(s):

Science
SC2015 (2015)
Grade: 2

3 ) Demonstrate and explain how structures made from small pieces (e.g., linking cubes, blocks, building bricks, creative construction toys) can be disassembled and then rearranged to make new and different structures.

NAEP Framework

NAEP Statement::
E4.6: Some Earth materials have properties either in their present form or after design and modification that make them useful in solving human problems and enhancing the quality of life, as in the case of materials used for building or fuels used for heating and transportation.

NAEP Statement::
P4.4: Some objects are composed of a single substance; others are composed of more than one substance.

Unpacked Content

Scientific And Engineering Practices:

Constructing Explanations and Designing Solutions

Crosscutting Concepts: Energy and Matter

Disciplinary Core Idea: Matter and Its Interactions

Evidence Of Student Attainment:

Students:

Demonstrate the disassembling of a structure into small pieces.
Demonstrate the rearranging of the same small pieces into a new and different structure.
Explain orally or in writing how the structure was disassembled and reassembled into a new and different structure.

Teacher Vocabulary:

Demonstrate
Explain
Structure
Pieces
Disassemble
Rearrange
Different

Knowledge:

Students know:

Different properties are suited for different purposes.
A great variety of objects can be built up from a small set of pieces.
Structures can be disassembled and rearranged into new and different structures.

Skills:

Students are able to:

Disassemble a structure into small pieces.
Assemble a new structure using the same small pieces.
Provide a written and/or oral explanation that correlates with a demonstration detailing the characteristics of the new object or objects.

Understanding:

Students understand that:

Structures may be broken into smaller pieces and a new structure, that is different in size or shape, can be formed from the same pieces.
