Part Two: Questions
These are general questions that will help you review the needed information for the test. If you can answer these and
understand the topics above, you will be ready for the test.
1. A student wants to see if changing the amount of sugar in Lemonade will alter the amount that is sold at her
lemonade stand.
a. Write a hypothesis for this experiment
b. What the independent and dependent variables. Explain why.
c. Describe 3 controls in this experiment. Why are they controls
d. Make up some sales results and then graph it out.
e. Write a conclusion to the problem based on your results.
2. Explain what matter is. Matter on Earth is found as either a solid, liquid or gas. Make a drawing of the atoms of a
solid, liquid and a gas. List three characteristics of each phase and how it is possible to change from one phase to
another.
3. Density is one property of matter. Explain what density is and how density is calculated. Describe two ways it is
possible to increase an object’s density and why this would increase the density.
4. Explain what the law/rule of density is and how it affects objects that are placed into a liquid. Using this rule. For each
object listed below, state whether they would sink or float in each of the liquids and why.
Object A: Mass = 5g Volume = 10 ml
Liquid 1: Density = 1 g/ml
Object B: Mass = 5 g Volume = 5 ml
Liquid 2: Density = 1.5 g/ml
Object C: Mass =10g Volume = 5 ml
Now imagine you put all of the listed items into one beaker. Make a drawing that would show where each would float.
5. Make two drawing of the earth’s interior. One of the Compositional view of the earth’s layers and one of the physical
structure layers. List one fact about each layer. Finally describe 3 differences between the two views of the earth and
one similarity of the views.
6. List and make a drawing of the different types of plate movement and boundaries that result. Describe what is formed
at each type of boundary and why they form.
7. Explain what sea floor spreading is, what causes it to happen. Give detailed causes of the movement of the sea floor.
8. Heat is able to move from one object to another. Describe the three ways that heat transfers and give one example of
each.
9. Explain what a destructive force is and why weather and erosion are considered destructive forces. Describe three
ways that rocks are weathered and three ways they are eroded. Give specific details
10. List the three types of rocks and how they form. Be sure to describe the different ways that each type of rocks can
possibly form.
11. Make a drawing of the rock cycle. Be sure to label how each part of the rock cycle is connected. Use this drawing to
explain why there is always the same amount of rock on the planet earth.
12. Explain what a fossil is, the difference between a body fossil and a trace fossil, and four different ways that fossils can
form. Then describe the two different ways that scientist could determine the age of the fossil and how these ages are
different from one another.
13. Explain what a mineral is and how it is related to a rock. List and describe 5 tests that a scientist could do to a mineral
to help determine what type of mineral they are looking at.
14. Describe the difference between a renewable and nonrenewable resource. List three renewable resources found in
Nevada and three nonrenewable resources that are found in Nevada. The nonrenewable resources in Nevada are
normally found by mining. Describe 3 dangers associated with mining and three reasons why it is important that we
continue to mine for materials.
15. Explain what a fault is and what causes a fault to form. Make a drawing of how the land moves at the different types
of faults and what type of plate movement and pressure cause them to form. Finally the landscape of the SW of the
US was formed by faults and plate movement. Make a drawing that shows how this formed and why the drive to LA
form Las Vegas is up and down.
