4. Skills Unit Review
1. Scientific Method
Students want to test if guinea pigs grow larger if kept in warmer cages. They decided to measure the temperature of the cages in Celsius and the size of the guinea pigs in grams. During the experiment, they fed the guinea pigs the same type and amount of food each day, housed the pigs in the same types of cages with the same type of exercise equipment and shelter, and gave the pigs the same amount of water. The students measured the size of the guinea pigs each day in the evening for thirty days. a. What is the Independent Variable? b. What is the Dependent Variable?

5. 2. Scientific Method
Students want to test if guinea pigs grow larger if kept in warmer cages. They decided to measure the temperature of the cages in Celsius and the size of the guinea pigs in grams. During the experiment, they fed the guinea pigs the same type and amount of food each day, housed the pigs in the same types of cages with the same type of exercise equipment and shelter, and gave the pigs the same amount of water. The students measured the size of the guinea pigs each day in the evening for thirty days. What are 5 constants the students controlled during the experiment? (There are more than 5 if your imagination is working hard!)

6. 3. Scientific Method
Students want to test if guinea pigs grow larger if kept in warmer cages. They decided to measure the temperature of the cages in Celsius and the size of the guinea pigs in grams. During the experiment, they fed the guinea pigs the same type and amount of food each day, housed the pigs in the same types of cages with the same type of exercise equipment and shelter, and gave the pigs the same amount of water. The students measured the size of the guinea pigs each day in the evening for thirty days. Write a hypothesis for this experiment. (If… then… because… )

7. 4. Interpreting Data
Some business savvy kids set up a lemonade stand on their corner and tracked their sales according to the temperature outside. The data they collected is shown on the right.
What temperature resulted in the best sales?
If the temperature outside were 50 degrees F, predict what how much money they could make in sales?
Predict how much they could make if the temperature were 78 degrees F.

8. 5. Interpreting Data
Students conducted an experiment to test how the acidity of soil affects plant growth. The students measured the acidity by taking the pH of the soil and they measured the height of the plants in cm. The results they collected are shown on the right.
What pH resulted in the tallest plants?
If the pH rose to 7.4, how tall would you expect those plants to grow?
How tall would you expect the plants to grow if the pH were 6.5?

Write the following numbers in scientific notation:
0.0006
340
6.7
71 x 103

10. 7. Scientific Notation A x 10B
Explain why the following number is NOT in scientific notation: 44.4 x 104
Write the following number in Standard Notation (the long way):
2 x 103
5.6 x 10-3
8.001 x 100

17. 14. Hypothesis
Ms. Bankoff’s cat, Fluffy, wasn’t eating enough. Ms. Bankoff went to the pet store and bought many different kinds of food and fed Fluffy a different type every day for 15 days. Each day she measured how much Fluffy ate out of his dish. Fluffy is the best worst cat ever. Write a hypothesis for the experiment.

18. Power (W) = Mass x Acceleration of Gravity x Height ÷ Time
This windmill is used to pump water from an underground well. Using the following information, calculate the power of the windmill. Height water is raised: 25 m Acceleration of gravity: 9.8 m/s2 Time to raise the water: 15 sec. Mass of water raised: 50kg
Power (W) = Mass x Acceleration of Gravity x Height ÷ Time
