3. Anything that has mass and takes up space.
Define matter
Row 1, Col 1

4. Give one example of physical changes that matter can
Example: painting a door - changes color
Give one example of physical
changes that matter can
undergo.
1,2

5. Example: water and copper
Give 2 examples of pure
substances.
1,3

6. Give an example of a chemical change.
Example: penny in ketchup- makes the penny cleaner and it causes reactivity.
Give an example of a chemical change.
1,4

7. Made up of 1 or more of the same kind of atom chemically combined
Define element
2,1

8. Give one example of a chemical
Example: burning wood – makes ashes and gases
Give one example of a chemical
change that matter can
undergo.
2,2

9. What is a pure substance?
A pure substance is a substance that has definite physical and chemical properties such as appearance, melting point, and reactivity.
What is a pure substance?
2,3

10. Give an example of a physical change
Example: licking a lollipop – changes size and shape
Give an example of a physical change

11. Define Law of Conservation of mass
States that in ordinary chemical and physical changes, mass is not created or destroyed, but is only transformed into different substances.
Define Law of Conservation of mass
3,1

12. How is mass different than
Example: Mass is how much space an object takes up and weight is the measure of gravitational force on an object.
How is mass different than
weight?
3,2

13. How are elements and compounds different.
Elements are made up of one or more of the same kind of atom chemically combined and a compound is made up of different kinds of atoms chemically combined.
How are elements and
compounds
different.
3,3

14. chemical or physical change?
When water boils, is it a
chemical or physical change?
3,4

15. Define physical change
Is a change that affects 1 or more physical properties of a substance.
Define physical change
4,1

16. Describe the difference between a chemical and physical change.
Example: a chemical change changes into a new substance and a physical change changes either the color, size, shape, or texture, it does not change into a new substance.
Describe the difference between a
chemical and physical change.
4,2

17. Do physical changes such as melting, freezing, or smashing
No, because if you have a penny and you smash it, the material will still be copper but it just looks a little different.
Do physical changes such as
melting, freezing, or smashing
change the identity of a pure
substance?
4,3

18. When you bake a cake, is it a chemical or physical change?
Chemical change
When you bake a cake, is it a
chemical or physical change?
4,4

19. Define chemical change
Occurs when 1 or more substances change into entirely new substances with different properties.
Define chemical change
5,1

20. When ice melts is it a physical
Example: When ice melts, it is a physical change because ice is water. When ice malts, it stays water and does not change into a new substance.
When ice melts is it a physical
or chemical change and why?
5,2

21. Is a mixture a pure substance?
No, because a mixture is not chemically combined.
Is a mixture a pure substance?

22. When you sharpen a pencil, is it a physical or chemical change?
Physical change
When you sharpen a pencil, is it
a physical or chemical change?
