4. A. Using water displacement (Figure 2), calculate the volume of the rock. Show your work & correct unit!
B. If the mass of the rock = 60 grams, what is the density of the rock? Show your work & correct unit!
5. Compare and contrast the 3 states of matter. Include information about each one’s shape, volume, the
arrangement and motion of particles.
6. In an atom:
A proton is:
A neutron is:
An electron is:
The atomic number equals:
The mass number equals:
7. Given a periodic table:
How do you find the number of protons in an element?
How do you find the number of neutrons?
How do you find the number of electrons?
8. What is the difference between an element, a compound and a mixture? Give an example of each.
9. What is the difference between a chemical and physical change? Give an example of each.
10. List and describe the six phase changes and whether energy is gained or lost to cause each one.
11. Density of Liquid A = 1.98 g/mL
Density of Liquid B = 0.75 g/mL
Density of Liquid C = 1.14 g/mL
Density of Liquid D = 0.50 g/mL
If the liquids were poured into a beaker, they create a density column.
Using the densities, label the beaker.
12. Write the formula to calculate density. What is the density of the object if the mass is 250 grams and has a
volume of 500 ml? Will this object sink or float when placed in water? Explain your answer.
Below is a scenario. Read it carefully and answer Questions #13 - 18.
A. Shara wanted to find out if flowers grew faster with sugar in the water.
B. She believed the sugar would make the flower grow faster.
C. Shara filled 4 jars with 200 ml of water. Jar A had 10 ml of sugar added; Jar B had 20 ml. of sugar
added and Jar C had 30 ml. of sugar added.
D. Jar D had no sugar in it.
E. The flowers in the sugar water all died. The more sugar in the water, the faster the flowers died.
F. The flower in Jar D ( no sugar) lasted for 10 days.
13. Which letter represents the problem? _______________
14. In which statement does Shara state her hypothesis? ____________________
15. What is the control in the experiment? _______________________________________________________
16. What is the independent variable in this experiment? ___________________________________________
17. What is the dependent variable in this experiment? ____________________________________________

24. List the two classifications of igneous rocks. Define and give an example of each.
25. List the three classifications of sedimentary rocks. Define and give an example of each.
26. Name and describe the 5 agents of physical weathering
27. Explain why fossils are usually found in sedimentary rocks rather than igneous or metamorphic rocks.
28. How are rocks and minerals similar? How are they different?
29. How do animals aid in soil formation?
30. Bedrock has been exposed at the surface, what are the steps/processes involved to create a developed soil
profile?
31. Draw and explain the processes within the rock cycle.
