Lesson/Unit Plan

Overview:

In this lesson, students will be able to explain that snap cubes or other objects can be used as models of atoms. Students will also be able to explain that atoms can be rearranged to make different molecules.

Students see an animation showing that the things around them are made of atoms and molecules. Students are given white, red, blue, and black cubes that represent hydrogen, oxygen, nitrogen, and carbon atoms. Students are guided to take atoms apart, rearrange them, and put them together again in different ways to make six different molecules. Students also see a fun molecule-making game that they can try.

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.
