Problem Independent Variable Scientific Method Dependent Variable Control Variable Hypothesis Part 2: Label the Layers ↑ Part 3: Complete the paragraph below by filling in the correct word for each sentence. Mark has to do an experiment for his schools science fair. He decided to experiment with milk and plants. His ____________ was “What is the effect of milk on plant growth?” He begins his ______________ by using the internet to identify the ingredients in milk. He then creates a _________________ that states: “If milk is used instead of water, then the plants will stop growing.” Part 4: Underline the independent variable and circle the dependent variable. 1. If the snow is soft, then the skier will go faster. 2. If the speed of the aircraft is slower, then there will be more air resistance. 3. If the string is tight, then the ant will walk across the string faster. 4. If a glue stick is left out in the sun, then the glue will melt faster. 5. If the temperature of the room decreases, then the fruit will last longer. Part 5: Answer the following questions: 1. What is the correct format for a hypothesis? a. I think the football will travel faster when the wind speed is decreased. b. If you move the wind chime to the left, it will make a louder noise. c. If the basketball has more air in it, it will bounce higher. d. If the sky diver jumps from a higher altitude, then velocity will increase. 2. When you are researching a topic, is it ok to just use one source and not cite it? Explain! 3. In the scientific method, the problem is: a. always a statement. b. never a question. c. always a question. d. an exclamation. 4. A hypothesis is: a. never a correct guess. b. always a prediction based on your research. c. sometimes a question. d. always happy. Part 6: Put the following layers of the Earth in order from MOST dense to LEAST dense Outer core Asthenosphere Lithosphere Lower Mantle Inner Core Crust Part 7: Answer the following question: How many types of variables are found in an experiment? Name and describe all of them. Part 8: In the space below, sketch and label the layers of the Earth involved in Convection Currents. THEN draw in the currents. FINALLY, describe what a convection current is and how it affects the planet (one or two sentences)!
