DO NOT WRITE ON THIS PAPER!!
This is a test grade!!!! This is due on Fri. You can use any resource you would like to answer these
questions. Internet, textbook, tutoring, class-time and my website through KISD are all good options.
Section 1
1. Show electrical charges and location of Protons, Neutrons, and Electrons.
2. What do protons tell you about the atom, what do the number of valence electrons tell you about the
atom?
3. In the periodic table, where are metals, nonmetals, and metalloids? Where are groups and Periods
and what do they tell you?
4. In 2Ca2SO4 How many: Ca atoms? Elements? Compounds?
5. Put in the coefficients to balance this chemical equation. __Al + __Fe3N2  __AlN + __Fe
6. Fe + O  FeO (rust). How do the properties of the reactants differ from the products?
Section 2
1. Show two objects pushing on a 3rd object. Give the net force and direction of that object.
2. How is speed different from velocity. How is acceleration different from speed?
3. Give an example of how Newton’s law of inertia would affect the car and the no seatbelt wearing
driver in a car crash.
4. Newton’s law of force and acceleration says: F=mass x acceleration. Show or answer a and b below.
a. If an object has a high mass, how does that affect acceleration and force
b. If an object has a low acceleration and high mass, how is the force different from an object with low
acceleration and low mass?
5. The law of action and reaction can be applied to a sling shot. How?
Section 3
1. How long does it take Earth to rotate through day and night?
2. Draw the tilted earth rotating around the sun and label the 4 seasons in the Northern hemisphere
above each Earth drawing.
3. Draw and label all 8 phases of the moon around earth.
4. Draw both neap and spring tides showing the Sun, Earth, and Moon in the correct positions. Label
where the ocean’s water level is the highest and the lowest.
5. Draw out a map of a stars life cycle from nebula to returning to a nebula.
6. Quick sketch! Draw and label the three types of galaxies. What is a galaxy?
7. Where on an H-R diagram would you find:
a. White dwarf
b. Main sequence star
c. Red Supergiant
8. What do we use to measure far distances across space?
9. Alfred Wegener discovered early contents (pangea) fit together like a puzzle. How is it thought they
moved apart over time?
10. Describe the process of moving plates that explain how these are made:
a. Earthquakes
b. New sea floor
c. Valleys
d. Trenches
11. Draw a simple topographic map of some land structure. Then after it eroded, draw a new
topographic map that would represent its new state.
12. How is wind created? Deep ocean currents?
13. High pressure air masses are ____ air while low pressure air masses are ____ air. When these two
collide, it is called a _____?
14. Warm water provides enough energy to heat the air above it. These conditions can start a spinning
motion causing what?
Section 4:
1. Give an example of 4 organisms. One from each tropic level. Give one example of a parasite/host
relationship.
2. Show a food web with 5 organisms. Label one predator and one prey.
3. Give 2 examples of competition. One between producers and one between consumers. What are they
competing for? Are your examples competing for biotic or abiotic factors?
4. Give an example of a long term environmental change and how it can affect traits seen in a
population.
