Properties and Structure of Matter Review Puzzles NGSS MS-PS-1 Chemistry

Type a

A set of 8 puzzles that have students practice critical thinking skills and apply concepts related to the physical and chemical properties of substances. Identifying models of molecules using a key, identification of elements, compounds, mixtures, and extended structures. Includes two different puzzles related to density calculations and using density to identify the type of matter and reviews vocabulary related to the structure of matter. The puzzles are designed to align with the NGSS physical science standards.

Usage Recommendations: These worksheets are versatile and can be utilized for independent practice, in stations, as homework assignments, or as part of emergency substitute teacher plans for unexpected schedule changes.

NGSS Standards Addressed:

• MS-PS-1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
• MS-PS-1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

3. How does a bird with a broken wing land safely? NGSS MS-PS-1-1. Students practice identifying the models as elements, molecules, extended structures, compounds, or mixtures.
4. Rabbit Hidden Message NGSS MS-PS-1-1 Students are asked to determine if the statements are true or false. These represent common misconceptions about the structure of atoms and substances. Explanation for False Statements is included in teacher notes
5. What is an alien’s favorite treat? NGSS MS-SP1-2. Students practice calculating density and determine if the material would sink or float in water
6. Alien Hidden Message NGSS MS-SP1-2. Students practice calculating density and determine if the material would sink or float in water
7. Fish Hidden Message NGSS MS-PS-1-1. Students practice identifying the models of molecules and compounds using the key.
8. What would you get if you crossed Christmas with St. Patrick’s Day NGSS PS-1-1 This puzzle requires students to use data about the mass and volume of 8 different coins and a data table to determine the letter code for solving the riddle.

• Students can be expected to know the formula for density and fill it in the provided space or you can give students the formula in advance.
• Coin 4 requires students to use deduction skills to determine the correct volume of the coin.
