Physical and Chemical Properties Data Analysis
Written by Adi Ackerman, Head Teacher
"Physical and Chemical Properties Data Analysis" is written for 7th Grade (Ages 12-13), and it covers NGSS MS-PS1-2. A 6th grader who is already steady on matter can use it too, and an older student can use it as a short review.

7th grade science worksheet: sort properties like density and rusting, then use before and after values to spot a reaction. Answer key included. Part of our states and properties of matter collection. Aligned to NGSS standards.
How do I use this worksheet?
Assign the water reading sheets together, then use the properties sheet as a data task. Students can use the printed tables and diagrams for every answer.
What students will practice
- Students will sort properties into physical and chemical groups.
- Students will compare before and after values to decide whether a reaction happened.
- Students will name each sample from a reference table and give one reason.

FAQ
How do I use this states and properties of matter worksheet?
⌄
Assign the water reading sheets together, then use the properties sheet as a data task. Students can use the printed tables and diagrams for every answer.
What does this worksheet teach?
⌄
Sort properties like density and rusting, then use before and after values to spot a reaction. The directions on the page read: Part A. Read the text. Write each bank item in the box where it belongs. An answer key is included.
Can I use this states and properties of matter worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade matter, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
What is cohesion?
⌄
Cohesion is the attraction between particles of the same substance. In water it causes surface tension, which lets a water strider stand on a pond.
Why does water dissolve so many substances?
⌄
A water molecule is bent and polar, so its oxygen end is partly negative and its hydrogen ends are partly positive. Those ends crowd around the ions of a substance such as table salt.
How do students tell a physical property from a chemical property?
⌄
A physical property can be observed without making a new substance, and a chemical property describes how a substance changes into new ones. Students sort ten properties, such as density and rusts, into the two groups.
Do students use data on these sheets?
⌄
Yes. One sheet uses before and after density and melting point values, and another uses a table of specific heat with the energy formula.
