The End

You have done it!! Congratulations! You are done with all of the assignments. (If you are not done with all of the assignments, please go back and finish them BEFORE you do this assignment.) You have nearly earned your .25 first quarter credit.


All that remains is a final course evaluation, a practice exam, and the final itself. Please complete the final course evaluation and the practice exam below. DO NOT DO THIS UNTIL YOU HAVE COMPLETED ALL OF THE PREVIOUS ASSIGNMENTS 1.1-1.14.


  1. What things (if any) did you like about the course?
  2. What things (if any) need to be changed?

Please complete the practice exam below. I will correct it and send you the results. This practice exam will be very helpful for you in taking the final.

Practice Exam

a. cat

b. wood

c. daisy

d. sunshine

a. control

b. procedure

c. hypothesis

d. variable

3. In a lake organisms die and decompose. Decomposition uses large amounts of oxygen that was dissolved in the lake’s water. The reduced level of oxygen in the lake would determine which of the following?

a. the number of trees living around the lake

b. the amount of rain water reaching the lake

c. the amount of clouds covering the lake

d. the kinds of water beetles living in the lake

4. You want to design an experiment that tests the influence of biotic factors on plant growth. Which biotic factor could you test?

a. types of insects infecting the plant

b. amount of water the plant gets

c. intensity of sunlight reaching the plant

d. amounts of nitrogen that fertilizer the plant.

a. The conclusion is invalid because James did not examine every city and every forest in the world.

b. The statement is invalid because it is difficult to determine the exact number of humming birds in an area.

c. The statement is valid because James did not find very many humming birds in the forest.

d. The statement is valid because James had a large sample size.

e. The statement is valid because James’ hypothesis matched his conclusion.

a. The relationship between amount of cloud cover and daytime temperatures.

b. The relationship between soil moisture and types of grasses present.

c. The relationship between the number of hawks and number of rabbits.

d. The relationship between number of grass plants and gopher holes.

e. The relationship between rainfall and stream volume.

In an investigation on potato bug habitat sites, Juan’s hypothesis was “There will be more salamanders found under rocks than on the bottom of the pond in the water.” Juan lifted up all the rocks in a pond and found 13 salamanders. In the water, on the bottom of the pond, he found 33 salamanders.

a. The location salamanders prefer.

b. the relative water temperature of the pond.

c. Salamander eating preferences.

d. The relationship between light levels and rock types at the bottom of a pond.

a. The conclusion is invalid because it disagrees with the hypothesis.

b. The conclusion is invalid because salamanders prefer hiding under rocks.

c. The conclusion is valid because there were significantly more salamanders found on the pond bottom than found under rocks.

d. The conclusion is valid because amphibians prefer hidden areas.

e. The experiment is a failure because the hypothesis was wrong.

Use the diagram below to answer the following questions.

rabbits foxes

grasses mice snakes bacteria

pea plants grasshoppers gulls

a. The whole food web would collapse.

b. There would be less grass for the mice.

c. The gull population would get smaller.

d. The fox population would get smaller.

e. The fox population would increase.

a. Foxes would over populate and kill off the rabbits.

b. Dead plants and animals would not decompose.

c. The number of gulls would increase.

d. Snakes and foxes would eat all of the mice.

e. Snakes would get sick and die.

A farmer wants to know how to get more ears of corn from his land. You are going to conduct an experiment to help him. You decide to plant 10 corn seeds in 10 different pots. You fertilize 5 plants with a 100 ml of a 5% fertilizer solution once weekly and 5 plants with 100 ml of a 25% fertilizer solution once weekly.

a. How do you keep the deer from eating the corn?

b. How tall can a corn stalk grow?

c. How can you get more ears of corn?

d. How can you get more plants on his land?

a. If you water the plant more then you will get more corn.

b. If you fertilize the plant more than you will get more corn.

c. If you spread out the plants more you will get more corn.

d. If you give the plant more light you will get more corn.

13. Consider the claim “All life is interdependent.” What would be at least one thing that would have to happen for this claim to be called a theory?

a. It would have to be supported by a lot of data that had been tested repeatedly.

b. The claim would have to be proven to be true by the scientific community.

c. Ecosystems would have to depend on biodiversity.

d. Science would have to start accepting new theories.

a. Tropical rainforest

b. Desert

c. Deciduous forest

d. Grassland

a. matching fossil records

b. similar rock layers

c. distribution of earthquakes and volcanoes

d. the way the continental coastlines fit together like a puzzle.

a. Convergent movement

b. Divergent movement

c. Transform movement

d. Biome movement

a. Sea floor spreading in the Atlantic Ocean.

b. Sea floor spreading in the Pacific Ocean

c. The coastlines of Africa and South America have similar fossils.

d. Volcanic activity in the Hawaiian islands.

a. They are spread evenly around the globe.

b. On plate boundaries.

c. On continents.

d. On the sea floor.

e. In mountains.

  1. How does energy flow through an ecosystem?
a. The sun’s energy is captured by plants during photosynthesis and eventually returns to space as heat.

b. Energy from the sun is used in the ecosystem and then it returns to the sun.

c. Energy from the sun is captured by animals to make sugars and fats.

d. The sun’s energy is captured by oxygen molecules, which causes respiration.

a. The design was valid because Tess measured the absorption of solar energy.

b. The design is valid because she used two variables; different materials as well as different types of cups.

c. The design is flawed because she used two variables; different materials as well as different types of cups.

d. The design is flawed because water temperature cannot be used as an indicator of the absorption of solar energy.

e. The design is flawed because 60 minutes is not long enough to measure the absorption of solar energy

21. Explain how the energy you use to dance at the Prom originally came from the sun. Be specific in describing how the energy flows from the sun to you on the dance floor. Use at least four steps.

Once I have received the above information, I will correct your practice exam and will give you feedback. Then I will submit your name to the EHS proctor manager. At that point, you will be done with me. The proctor manager will contact you and will make arrangments for you to take the final. If you do not hear from the proctor manager in a timely manner, contact the EHS office. Once you are done with the final exam, the proctor manager will correct your exam and will assign your final grade.
