Characteristics of Science Read the following experiment to answer questions #1-4. Jane finished a book report on plants. She knew that plants grew best in an environment full of light and much water. To prove what she had learned Jane wanted to test the growth of plants according to different biomes. She planted 10 bean plant seeds in each of the 6 different land biomes. Each bean plant seed was planted 8 centimeters from the surface and equally spaced from each other. For 10 days she and her experiment partners would record the height of the plants at the same time of the day. 1. Name the controlled variable(s): 2. Name the manipulated variable(s): 3. Name the responding variable(s): 4. Write a hypothesis using the above experiment. Using the above statement pick out the following types of observations for #5-6. Jane studied the growth of plants in different biomes. She noticed that the plants in the wet tropical rainforest environment on average grew to be 10 meters long and had many green leaves on there stem. When she observed the plants from the dry desert environment she noticed that the plants on average grew only ½ meter tall and had only a few leaves that were brownish yellow in color on there stem. 5.

Write what step of the scientific method each statement represents. Parts of the Scientific Process: Problem, Research, Hypothesis, Experiment, Results, Conclusion Search the library for information on water temperature and fish survival. Do fish react to water temperature? If fish are put in water of 67 C, then they will die within 30 days. Take two groups of equal number of fish and put them in two tanks of the same size and the same kind of water, but different temperatures. Observe their behavior. My hypothesis was correct because the fish in 67 C water died within 30 days. Fish in 67 C water died within 30 days.
Read the passage and answer the questions below. A researcher wants to determine if a certain type of energy drink makes athletes run faster. The researcher will time the athletes in a 40-yard dash before and after drinking the energy drink. The researcher gives the drink to 3 basketball players, 3 football players, 2 baseball players and 2 tennis players, for a total of 10 athletes. When he times the athletes, he finds that 6 of the 10 athletes run faster in the second 40-yard dash. The researcher reports to the drink company that the energy drink makes most athletes run faster. 14a) What was the hypothesis being tested by this researcher? 14b) The researcher reported that the energy drink makes most athletes run faster. Is that an accurate claim for the researcher to make? Give two (2) reasons why the claim is or is not accurate. 14c) What might be the next step for this researcher, if he wanted to strengthen his claim that the energy drink makes most athletes run faster? Read the passage and answer the questions below. A gardener wants to find out what type of fertilizer grows the largest tomatoes. She plants 4 tomato plants in the same size container, gives them the same amount of water, and each plant receives the same amount of light each day. Each of the 3 containers has a different type of fertilizer and the fourth gets no fertilizer. After 4 weeks, the tomatoes are ready to be picked. The gardener finds the mass of each tomato from each container. Brand A container: 200g, 219g, 217g, and 130g Brand B container: 122g, 110g, 145g, and 111g Brand C container: 167g, 214g, 220g, and 143g No fertilizer container: 98g, 123g, 130g, and 102g 15a) What is a possible hypothesis that the gardener could have for this experiment? 15b) Find the average mass of the tomatoes grown in each container.

Match the Biomes with the following Characteristics: Taiga Tundra Freshwater Temperate Deciduous Forest Savanna Marine Estuary Tropical Rainforest Desert Biome Characteristics 12. Found in regions close to the equator. Receive a lot of rain & warm temperatures throughout the year with constant sunlight. Many diverse animals & tall trees form a canopy. 13. Receives less than 25 cm. of rain per year. Very dry and warm climate. Animals & plants store water to adapt to the lack of rain. Animals are active at night & plants have a thick & waxy covering. 14. Sometimes called a prairie, the temperature here is comfortable because it is located in the middle latitudes. Receives 25-75 cm. of rain per year, not enough for trees to grow. Typically populated by grasses & home of the largest animals such as bison, antelopes, giraffes, & rhinoceros. 15. Lots of trees that shed their leaves & grow new ones each year are found here. Receives 50 cm. of rain per year, enough to support the growth of trees & plants. Temperatures vary during the year with all the seasons. Many birds, opossums, bears, & porcupines are found here & may migrate or hibernate in the winter. Found in the eastern part of the United States. 16. Here in northern Canada you will find many trees that have needle like leaves & produce seeds in cones such as pine, fir, & spruce trees. Winters are very cold with much snow & summers are warm enough to melt the snow and bring much rain. Trees have a waxy covering, a necessary adaptation to keep water from evaporating since much of the year the water is frozen. Many herbivores live here such as deer, elk, moose, & beavers that attract large predators such as wolves, bears, & lynxes. 17. Most animals here have gills to take in oxygen & fins to swim. Consist of still (ponds & lakes) and running (streams & rivers) water. Algae out numbers plants because they can float & don t need to be rooted. 18. Largest of all biomes because it covers 70% of the earth s surface. Many animals that are adapted to live in saltwater live here. 19. Extremely cold & dry biome located in the artic regions. Receives little precipitation like the desert but here most of the soil is permanently frozen. No trees grow here because of the permafrost not allowing for roots to grow. The top layer of soil thaws for grass to grow. Herbivores graze on the grass or lichen & have thick fur to withstand the freezing climate. 20. This is a very productive, very diverse, and wet biome. It is the place where a river meets the ocean, producing a salt/fresh water mix. Large amounts of nutrients carried by the river and lots of sunlight make it a good habitat. Producers include marsh grass and algae. Consumers include crabs, worms, clams, oysters, and fish. Used as a breeding ground by many ocean animals. 21. Name an adaptation that enables the musk ox to survive in its environment. Musk Ox 22. If the climate changed to become much warmer in the environment where the musk ox lived, how might this affect the musk ox?

An organism with no nucleus is discovered living in high temperature hot springs. It most likely belongs to the kingdom.
Evolution 1. In Manchester, England the Peppered Moth come in both gray and black varieties. Under normal conditions, the moths are mostly grey, allowing them to blend into the tree bark of their habitat. Using the concept of natural selection, explain what happened to the grey peppered moth population after the Industrial Revolution occurred in Manchester. 2. What are the four parts of natural selection? a) b) c) d) 3. Animals have many adaptations for survival. Describe each adaptation below, and explain how it could help an organism better survive in its environment. a) camouflage b) mimicry c) venom

In the Galapagos Islands, Charles Darwin found many different species of finches (a type of bird) that seemed closely related. He proposed that the birds had all evolved from a common ancestor. Match the bird beaks below to the most likely food source. 6. Each of the 5 different finch species shown above are evolutionary descendents of one species of finch that is extinct. Explain how the five finches pictured above most likely came to have different beaks.
