1. What type of change is the Statue of Liberty an example of?
1. Chemical Change
4. Does a brick or a sponge have more gravitational pull acting on it?
4. A brick
3. Give an example of a substance that has the physical property of malleability.
3. Aluminum foil
2. Do a sponge and a brick have the same mass?

Which has more?
2. No, a brick has more mass.
7. Do a sponge and a brick that are the same dimensions have the same volume?
7. Yes, they are about the same size.

V= L X W X H The answer would be the same for both if they have the same dimensions.
6. Give four examples of physical properties.
#6
1. Color
2. Volume (Size)
3. Odor
4. Malleability
5. Taste
6. Texture
7. Shape
5. After a substance has gone through a chemical change is there any way it can be undone? How?
5. Yes, it can be undone by another chemical change.
10. Give an example of something that is not matter.
#10
1. Thoughts
2. Sunlight
9. Is a "state" a physical or chemical property?
9. Physical
8. Define meniscus.
8. The meniscus is the curved line of a liquid where you read the volume on the lowest part of the curve.
13. Are weight and mass the same thing?
13. No, weight changes with gravity.
12.What is the ability to burn called?
12. Flammability
11. What type of change occurs when a popsicle melts?
11. Physical change
16. Give three examples of chemical properties.
#16
1. Flammability
2. Ability to Rust
3. Ability to Corrode (Reactivity with oxygen)
15. Which has the most gravitational pull on it--an elephant or a ping pong ball?
15. An elephant has the most gravitational pull because it has the most mass.
14. Which has the least amount of matter---an elephant or a ping pong ball?
14. A ping pong ball has less mass so it has less matter.
19. What type of change is butter melting on toast?
19. Physical change
18. What type of change is it when you break your pencil in half?
18. Physical Change
17. Define mass.
17. Mass is the amount of matter something is made of.
22. Define chemical change.
22. A chemical change occurs when one or more substances are changed into entirely new substances with different properties.
21. Define malleability.
21. Malleability is the ability of a substance to be pounded into thin sheets.
20. Define matter. (Short Answer)
20. Matter is anything that has mass and volume.
25. What is the difference between mass amd weight? (Short Answer)
25. Mass is the amount of matter in something and it does not change. Weight is a measure of gravitational force and it changes when gravity does.
24. What would be harder to carry in a sack on your back--- 10kg of books or 10kg of feathers?
24. The feathers would be harder to carry. They both are the same weight but 10kg of feathers would be very large and bulky.
23. Give an example of something that could happen to a can that would be a chemical change. (Short Answer)
23. A chemical change would occur if the can rusted, or oxidized.
28. List three physical properties of a can that has been crushed. (Short Answer)
28. Three physical properties are silver color, crushed shape, malleable.
27. What does matter always retain during a physical change?
27. Its identity.
26. When a can is crushed, it is a physical change or chemical change? (Short Answer)
26. Physical Change
