Hypothesis A testable prediction Control Group that receives the "normal" conditions Independent/ Manipulated Variable The variable that the scientist changes Dependent Variable The variable that is measured Constant A condition during the experiment that stays the same for all groups being tested Observation Using your five senses to determine information Inference Drawing a conclusion using the evidence at hand Multiple Choice Read the questions carefully. Choose the letter of the best answer. Which of the following puts the steps of a scientific experiment in the correct order?I. Make a predictionII. Ask a question.III. Make a conclusionIV. Gather data. II, III, I, IV II, I, IV, III II, I, III, IV IV, II, III, I What is the purpose of an experiment? To communicate data To test a hypothesis To prove a scientific law None of the above Global Warming Experiment Iker is worried about global warming. He believes that much of the problem is caused by the intense heat that comes from the surfaces of streets and the roofs of buildings. Iker convinces his teacher to do an experiment. With the help of other students, Iker builds a rooftop garden to cover one half of his school building. For one semester, Iker records the air temperature on the half of the building with the rooftop garden and the half of the building without the garden. He finds that the average temperature near the rooftop garden is 23°C. The average temperature away from the garden is 29°C. What is the manipulated variable for the Global Warming Experiment? Air Temperature Location Global Warming Time of Day What is the dependent variable for the Global Warming Experiment? Air Temperature Location Global Warming Time of Day What is a constant in order for the Global Warming Experiment to be valid? Air Temperature Location Global Warming Time of Day According to the data shown in the graph, the hypothesis is only correct for latitudes- up to 40 degrees from the equator from the poles to 40 degrees from the equator between 20 degrees and 60 degrees from the equator farthest from the equator There is a greater average humidity in the _. north south The largest number of male sea turtles will develop at 28∘ degreesC. Female sea turtles develop at higher temperatures. Most of the sea turtle eggs hatched if incubated at 26∘ degreesC. The sex of sea turtle babies depends on the incubation temperature. How much limestone was worn away between Day 1 and Day 2? 0.2 gram 0.5 gram 1 gram 2 grams According to this graph, which rock or mineral erodes the slowest? Granite Limestone Quartz Sandstone According to this graph, which rock or mineral erodes the fastest? Granite Limestone Quartz Sandstone Algal Bloom Put the steps of the scientific method in the correct order in the column on the left. Match the example with each of the steps in the right column. Click the box on the right to choose your answer from the Word Bank. Observation Mrs. Sandberg noticed that a lake was completely green from algae blooms (excessive growth). Hypothesis Mrs. Sandberg thinks the algae are thriving off nitrogen fertilizer running off from nearby farms. Experiment Mrs. Sandberg uses unique plants to absorb extra nitrogen to see if it prevents the nitrogen runoff. Gathering Data She counts the algae growth in the lake and finds that the algae growth has declined. Conclusion Her research shows that the unique plants likely absorbed the algae and can prevent blooms. Turtles lay eggs in holes that they dig in the ground. The temperature that eggs are incubated at determines whether the offspring are male or female. Warmer temperatures lead to more females. The normal soil temperature is 35C.Use the data table to identify the Constant, Control group, Experimental group, Independent Variable, and Dependent Variable. Constant Sand color Wind Speed pH of water Control Group Eggs incubated at 35o C Experimental Group Eggs incubated at 25o, 30o, 40o, and 45o C Independent Variable Temperature eggs are incubated at Dependent Variable Number of females hatched ASSIGNMENT: Make an individual self-introduction video answering the question: "Why is Physics important to me?"The video must include the following information.1.
